You will need to implement openURL: in your delegate.
Now, to have the application start with your new subclass of UIApplication, locate the file main.m in your project. In this small file that bootstraps your app, there is usually this line:
int retVal = UIApplicationMain(argc, argv, nil, nil);
The third parameter is the class name for your application. So, replacing this line for:
int retVal = UIApplicationMain(argc, argv, @"MyApplication", nil);
I haven't tried that myself but you can try to implement application:handleOpenURL: method in your application delegate - it looks like all openURL request pass through this callback.
Not sure how you would intercept the detected data link, or what type of function you need to run. But you may be able to utilize the didBeginEditing TextField method to run a test/scan through the textfield if you know what your looking for..such as comparing text strings that meet ###-###-#### format, or begin with "www." to grab those fields, but you would need to write a little code to sniff through the textfields string, reconize what you need, and then extract it for your function's use. I don't think this would be that difficult, once you narrowed down exactly what it is that you wanted and then focussed your if() statement filters down to very specific matching pattern of what you needed.
Of couse this implies that the user is going to touch the textbox in order to activate the didBeginEditing(). If that is not the type of user interaction you were looking for you could just use a trigger Timer, that starts on ViewDidAppear() or other based on need and runs through the textfields string, then at the end of you run through the textfield string methods that you built, you just turn the Timer back off.
application:handleOpenURL: is called when another app opens your app by opening a URL with a scheme your app supports. It's not called when your app begins opening a URL.
I think the only way to do what Vladimir wants is to use a UIWebView instead of a UITextView. Make your view controller implement UIWebViewDelegate, set the UIWebView's delegate to the view controller, and in the view controller implement webView:shouldStartLoadWithRequest:navigationType: to open [request URL] in a view instead of quitting your app and opening it in Mobile Safari.
I have a 2.67 GHz Celeron processor, 1.21 GB of RAM on a x86 Windows XP Professional machine. My understanding is that the Android emulator should start fairly quickly on such a machine, but for me it does not. I have followed all instructions in setting up the IDE, SDKs, JDKs and such and have had some success in staring the emulator quickly but is very particulary. How can I, if possible, fix this problem?
A nice way to do this is to by subclassing UIApplication and ovewriting the -(BOOL)openURL:(NSURL *)url
ReplyDelete@interface MyApplication : UIApplication {
}
@end
@implementation MyApplication
-(BOOL)openURL:(NSURL *)url{
if ([self.delegate openURL:url])
return YES;
else
return [super openURL:url];
}
@end

This did the trick for me.

Instead of extending UIApplication you can just block the userInteraction of the UITextView
ReplyDeleteThis is working for me.
