I've run into a frustrating feature of KVO: all notifications are funneled through a single method ( observeValueForKeyPath:.... ), requiring a bunch of IF statements if the object is observing numerous properties. The ideal solution would be to pass a method as an argument to the method that establishes the observing in the first place, but it seems this isn't possible. Does a solution exist to this problem? I initially considered using the keyPath argument ( addObserver:forKeyPath:options:context: ) to call a method via NSSelectorFromString , but then I came across the post KVO Dispatcher pattern with Method as context and the article it linked to which offers a different solution in order to pass arguments along as well (although I haven't gotten that working yet). I know a lot of people have come up against this issue. Has a standard way of handling it emerged?

I have the following code: - (UIImage *) getPublisherLogo { //check the cache if the logo already exists NSString * imageUrl = [NSString stringWithFormat:@"%@/%@&image_type=icon", self.baseUrl, self.imageUrl_]; ASIHTTPRequest * imageRequest = [ASIHTTPRequest requestWithURL:[NSURL URLWithString:imageUrl]]; [imageRequest setTimeOutSeconds:30.0]; [imageRequest setDownloadCache:[ASIDownloadCache sharedCache]]; [imageRequest setCacheStoragePolicy:ASICachePermanentlyCacheStoragePolicy]; [imageRequest setCachePolicy:ASIAskServerIfModifiedWhenStaleCachePolicy|ASIFallbackToCacheIfLoadFailsCachePolicy]; [imageRequest setCompletionBlock:^(void){ UIImage *img = [UIImage imageWithData:[imageRequest responseData] ]; if (img){ return img; } }]; [imageRequest setFailedBlock:^(void){ NSLog(@"Error in pulling image for publisher %@", [[imageReq

Lets say that I add a subView to my view, like this: [[self addSubview:myView]; Then I push a new view onto the navigationController stack, like this: [self.navigationController pushViewController:otherView animated:YES]; What happens to the subView that I added to the original view. Is it removed automatically? Also, if my program calls this line: [[self addSubview:myView]; multiple times without removing the view does that do anything bad like create a memory leak?

I am experiencing either an extremely weird error or a temporary loss of brain function. I have a box2d / cocos project running in XCode. This all works fine but my code is currently a proof of concept "hack". Stage one of cleaning up the code is creating classes for various objects. Now, if I create a brand new Objective C class (inherited off NSObject) as below it all compiles fine. As soon as I attempt to import the "Box2D.h" I receive a gazillion errors originating from the box2d library saying it cannot be built. 201 to be precise and it indicates no issues with the class itself. Can anyone shed any light? I have already tried a clean and rebuild as well as restarting XCode. My super complicated class definition #import "Box2D.h" @interface test : NSObject @end An example compiler error thrown Expected '=', ',', ';', 'asm' or '__attribute__' before 'b2Fixture' in /Users/..../libs/Box2D/Dynamics

My main view controller only supports landscapeleft and landscaperight. This viewcontroller in the viewDidLoad has: if ([self.navigationItem respondsToSelector:@selector(leftItemsSupplementBackButton)]) { self.navigationItem.leftItemsSupplementBackButton = YES; self.navigationItem.leftBarButtonItem = homeBBI; NSArray *rightNavItems = [NSArray arrayWithObjects:searchBBI, allBBI, nil]; self.navigationItem.rightBarButtonItems = rightNavItems; } When I push my ReportViewController onto the stack, it looks fine. This controller also supports landscape only. - (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation { return UIInterfaceOrientationIsLandscape(interfaceOrientation); } When I rotate the iPad 180 degrees, all looks fine. However when I pop to the main view controller, the UINavigationBar gets messed up. It basically has all the items, including the title squished to the left. The search bar I had ends up taking up 75% of

I'm fairly new at iOS development so please forgive my ignorance. I have web view with a search form, sending request to display different pages depending on the search query. When displaying a selected page I want to have a normal html link at the top which will give the user the possibility to display all images available using the very nice MWPhotoBrowser. So somehow I need to tell Xcode to open MWPhotoBrowser using a link and when this link is pressed send a variable to MWPhotoBrowser and in that viewController somehow loop through a my url.com/variable. Is this the best way to do this and is it even possible? I have searched as much as possible but I'm not sure what to look for so I would really appreciate if you could point me in the right direction.

I'm communicating between an iPhone app and a server using XML. To get around the problem of the user entering any character that might break the XML before I send it to the server i'm using the NSString method: [string stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding]; But I noticed when doing a log of the string that the & symbol is not escaped? I thought that it should be? spaces, quotation marks and hash symbols which I've tested for all encode fine but not the ampersands? What is the most common methods used for encoding/decoding XML sent to/received from a server? Thanks.

Hi folks I have a iPhone 3GS at 4.2.1 and want to upgrade it to 4.3.x for testing. I have read some articles about it but it seems that those are too old and cannot work. Does anyone have some experience in doing this or does apple provide tutorials for developers in this? A lot of thanks.

I have a html page in a server, and load it with phoneGap for iPhone. In my html page, I call a native plugin but dont work. The same html page in local project, work well. I also have the JS plugin file in the server. How can I call a plugin in phonegap from a server page for iOS?

I'm writing my first SIMPLE DB app, basically, an offline db, select a listing of records, and then, click on one of those to display on the detail. I looked at an older book for an example (pre xcode 4) because it had an example very similar to what I needed to do. So the example set up all the methods I'd need to access the database in a member called DBAccess.m AND I can tell from the debugger that the code visits main.m and then MasterViewController.m it executes awakeFromNib and didViewLoad which is awesome... BUT where do I put my first statement that calls the routine I need that's in my DBAccess.m file? The book assumes you KNOW where to put your code and leaves it as an exercise for the user... ugh. I can't find any definitive statement about how you insert your code into the execution cycle. Is there a default execution cycle?

In interface builder there is a control in the struts and springs inspector that is labeled origin. What does this do and why does changing it for one object change it for ALL objects? As far as I can tell it doesn't have any real effect on the frame rectangle origin as the name implies. Let me explain: Selecting a UILabel and changing the origin to be at the top right as in the photo above puts the frame origin at the point (280,11). However, in code, when you actually ask the frame for it's origin it is given as (211,11) which corresponds to the top left corner of the frame. Therefore, changing the frame origin in interface builder appears to do absolutely nothing! What is going on here?!

In my app i am displaying my timeline but all the twitter names (@abcd)are not appearing as a link. Is there a way to do it???? Thanks,

I have been reading though heaps of the ios docs from apple, and almost every bit of code to do with xml on there requiers either creating a file with xml data in it or receiving xml over a connection then altering it. I would like to know if there is a way to just creat some xml.. maybe in a string, then convert it into a NSData object.. I know how to pass a nssting into a nsdata object.. thats not so much of a big deal.. the painfull part at the moment is getting some clear concise examples on how to create my own xml without all the other stuff that apple says you need.. I.e. file or return data. I currently have no code.. what I will likely do is create a method with some parameters that can receive some information and then pass them in to hopefully create a nice xml string/data object.. if you have any example code, suggestions links to decent tutorials that would be hugely helpfull :)

I have tried dozens of configuration settings trying to get this to work, but still to no avail... When I am trying to submit to the app store, the application loader is reporting the following error iPhone/iPod Touch: application executable is missing a required architecture. At least one of the following architecture(s) must be present: armv7. My understanding is that fpc 2.4 can only generate armv6 code anyway. I have tried setting all build settings to only reference armv6, installed the previous version of XCode 3.2.6 and linked with the iOS SDK 4.3, hoping that this will address any references to armv7, but still no joy. According to the XE2 Update 4 release notes, fpc 2.6 supports armv7, but despite the release notes having been available for weeks, there is no sign of the update! Has anyone successfully uploaded an app using current tools (it surely has to be possible), and if so, could you please share your secret! Thank you

I'm trying to set up a menu in my cocos2d game and whenever I import Game.h I end up with over 200 errors. It's a cocos2d app with box2d, I'm not sure why it's throwing all these errors though- the game was running perfectly before I swapped loading the Game scene for the MainMenu scene initially. The line of code I'm running is [[CCDirector sharedDirector] replaceScene: [Game node]]; The import of 'Game' causes the errors. Can anyone give me an idea about this? Some information that may be helpful... I originally created the project loading into Game.m but switched it to MainMenu and then import Game.h into MainMenu to access the object. ANY insight is appreciated! Thank you!

In my web browser, I am trying to load a UIWebView with NSData obtained from an NSURLConnection. When I try to load it into the UIWebView, instead of the site, it comes up with the HTML plain text. Here is my code: in viewDidLoad: NSURLRequest *request = [NSURLRequest requestWithURL: [NSURL URLWithString:@"http://www.msn.com"]]; [NSURLConnection connectionWithRequest: request delegate:self]; later in the code: -(void)connection:(NSURLConnection *)connection didReceiveData:(NSData *)data{ webdata = [NSMutableData dataWithData: data]; } -(void)connectionDidFinishLoading:(NSURLConnection *)connection{ [webview loadData:webdata MIMEType: @"text/html" textEncodingName: @"UTF-8" baseURL:nil]; }

My question is very simple, I would like to know if the method "CGImageSourceCreateWithData" creates a new object copying the data I provide so that that I have to release it when I don't need it anymore, or if it just creates a reference to the data I already have so that if I release it I will lose this data (and possibly have bad access errors). The issue is related to using (__bridge CFDataRef) as the source data. Which let's me use Core Foundation objects as toll-free in ARC mode. Consider the following function (or method, not sure how it's called): - (void)saveImageWithData:(NSData*)jpeg andDictionary:(NSDictionary*)dicRef andName:(NSString*)name { [self setCapturedImageName:name]; CGImageSourceRef source ; // Notice here how I use __bridge source = CGImageSourceCreateWithData((__bridge CFDataRef)jpeg, NULL); CFStringRef UTI = CGImageSourceGetType(source); NSMutableData *dest_data = [NSMutableData data]; // And here I use

I have a rails 3.0.3 website that, in development mode, responds to a HTTP GET by calling didReceiveData and then connectionDidFinishLoading, and photo data is sent from the website to the iPhone and displayed correctly. But when I run the rails 3.0.3 website in production mode, connectionDidFinishLoading is called before didReceiveData. I'm using carrierwave to handle the photos for both the development and production rails sites. Does anyone have any idea what could cause connectionDidFinishLoading to get called before didReceiveData? I've tried checking the following: 1) I made sure the NSURLConnectionDelegate is called for the class' interface. 2) didReceiveResponse gets called before connectionDidFinishLoading and the statusCode = 200. 3) In the rails app I am using send_file to send the photo data, and the path to the file sent in production, is an actual photo. 4) I checked that data was being returned from the production website by using the code below

When I do a Google image search on my iPhone within the Safari mobile browser, it gives me this beautiful interface for flipping through the images. If I swipe left or right, it browses through the images. If I touch and move up or down, I get what appears to be the native Safari scroll function. Can anyone explain how Google does this? I'm only beginning to learn the Safari API for touch events. It seems like either you capture the touch event to attach handlers to swipe left or right or you let Safari handle the touch events natively, in which case you get the beautiful native Safari scrolling. Can anyone explain how Google captures left/right swipe but not scrolling?

I'm writing an Android library and I wish to use a custom Application class, which will be accessible from all of the library's activities (using the getApplication method). The problem is when I call the getApplication method from one of my library's activities, it returns the application class of the app using my library (and not the custom class I declared in the library's Android manifest). My current guess (based on this answer and the official documentation ) is that the application using my library must also declare the custom Application class in their Android manifest - which is a problematic solution, since that application can also have its own custom class (and a single app cannot have more than one custom Application class, right?). Can anyone offer a better solution? (or verify that this solution is accurate) Any help will be appreciated..

How can I run my android junit/robotium tests from the command line on every single emulator? I want to make sure my tests run on many android OS versions and many screen resolutions. I'd like to write a batch file that runs from the windows command line to run my test suite over and over again on each emulator I have installed. To run from the command line I can do this: adb shell am instrument -w com.myapp.client.test/android.test.InstrumentationTestRunner but that just runs it on the default emulator. How can I force that command to run on all of the emulators I have setup? Ideally, the batch file would looking something like: launch emulator1 run tests close emulator1 launch emulator2 run tests close emulator2 ... I don't know how to do the launch and close part. Thanks EDIT: Found solutions. Below is my batch file set PORTRAIT=medium set LANDSCAPE=large :: launch emulator emulator -avd android2.2 :: wait for emulator to l

I looked through tons of articles how to open new Activity from ListView hosted by TabHost. I have a TabHost Activity, one of the tabs has ListView, with clickable list items. On item click, I want new Activity to be opened in the same FrameLayout. My code for calling new Activity looks as following: Intent intent = new Intent(v.getContext(), displayRSS.class); this.startActivity(intent); This opens just new Activity. I want new Activity to be opened instead of current ListActivity. Would appreciate any possible solutions on this.
