I am using custom Kal calender view library downloaded from github. I know very well and execute successfully how to create delegate protocol and implement them. But now in my application I have to do, when user click on date that date directly reflect to my UIViewController class. For that scenario I used @protocol delegate method but I got strange problem in it. Please see the following screenshot and suggest me where I am wrong, 
Then i synthesize my protocol 
but I got the below error. Why, where I am wrong?
You need to #import the .h header file where you have declared your KalViewControllerDelegate protocol.
ReplyDeleteFor the custom delegate and protocol for that best example for it
ReplyDeleteRefer the reference link here
Well, I downloaded the Kal from github. After reading the sample it provides, I am curious how you embedded the Kal into your project.
ReplyDeleteAs the sample project inside Kal, it embedded the Kal into project as the following image. And it imports the header named Kal.h in NativeCalAppDelegate.m. So, there may be something wrong about the setting of header search path for Kal inside your project. If you compiler the Kal into a static library, how you reference the header files of Kal ?
Not sure if that will help, but when I used Kal I did it that way:
ReplyDelete#import <UIKit/UIKit.h>
#import "SomeOfMyClasses.h"
#import "Kal.h"
@interface SomeRandomViewController : UIViewController<UITableViewDataSource, UITableViewDelegate, KalViewDelegate>
as you can see, I used KalViewDelegate and not KalViewControllerDelegate. Also don't forget to import "Kal.h".
Update
I did the following in my viewDidLoad method:
self.kvc = [[KalViewController alloc]init];
self.kvc.delegate = self;
self.kvc.view.frame = CGRectMake(0, 0, 320, 340);
and header file:
@property (nonatomic, retain) KalViewController *kvc;
Haha i was very curios about why you couldnt make it, so i decided to download the class myself. Funny thing is i DIDNT get any problems.
ReplyDeleteHere is what i did:
(i assume you want to create a new protocol for the class KalViewController.h)
so you add
Bellow the "@class KalLogic, KalDate;"
@protocol KalViewControllerDelegate <NSObject>
-(void)dateDidSelected:(NSDate *)selectedDate;
@end
then in the SAME header file where the properties are declared you add:
@property (nonatomic, assign) id<KalViewControllerDelegate> delegate2;
Please note that this header already has a delegate implemented
@property (nonatomic, assign) id<UITableViewDelegate> delegate;
so you have to name it something else other than delegate.
then on the implementation file of that class you syntethize that name:
@synthesize dataSource, delegate, initialDate, selectedDate, delegate2;
and then you can implmeneted that delegate whever you want. I have no idea what this kal project does so i picked a random file (in this case SBJSON.h)
and added the (on the header)
@interface SBJSON : SBJsonBase <SBJsonParser, SBJsonWriter, KalViewControllerDelegate> {
and (on the implementation)
- (void)dateDidSelected:(NSDate *)selectedDate
{
}
Hope this helps, Good luck
