Question

I am working in phonegap Camera API new to objective c i dont know how to declare method and interface for this function in .h file

if([(NSString *) [components objectAtIndex:1] isEqualToString:@"Take_Photo"])    
  {
            UIImagePickerController *picker = [[UIImagePickerController alloc] init];
            picker.delegate = self; 
            picker.allowsImageEditing = YES; 
            picker.sourceType = UIImagePickerControllerSourceTypePhotoLibrary;
            [self presentModalViewController:picker animated:YES];
    }

I’ve declared UIImagePickerControllerDelegate in .h file but the camera is not opening.
i did not get any error when i debugging the application paused after completed the line

[self presentModalViewController:picker animated:YES];

the application debugger paused in the binary file. i think i missed something in .h file.

 @interface NativeAPI :UIViewController        
  <UIWebViewDelegate,UIImagePickerControllerDelegate,UINavigationControllerDelegate>
   {

        Reachability* internetReachable;
        Reachability* hostReachable; 
         UIImagePickerController* Image_Picker;
    }

any one help me thanks in advance

Answer 1

You will be required to assign the value of the picker to the instance variable like this.

UIImagePickerController *picker = [[UIImagePickerController alloc] init];
self.Image_picker = picker;
[picker release];
Image_picker.delegate = self; 
Image_picker.allowsImageEditing = YES; 
Image_picker.sourceType = UIImagePickerControllerSourceTypePhotoLibrary;
[self presentModalViewController:picker animated:YES];

Try the code above

You can define a method under the implementation which is to be called by the delegate.
