Я делаю фотографию с моим приложением, вызывается метод делегата, изображение сохраняется в библиотеке, но в журнале появляется ошибка сбоя:
*** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '+[NSInvocation invocationWithMethodSignature:]: method signature argument cannot be nil'

terminate called after throwing an instance of 'NSException'
Мой код следующий:
- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info {
UIImage *pickedImage = [[info objectForKey:UIImagePickerControllerOriginalImage] retain];
UIImageWriteToSavedPhotosAlbum (pickedImage, self, @selector(photoSaved:::), nil);
}
-(void)photoSaved:(UIImage*)image didFinishSavingWithError:(NSError*)error contextInfo:(void*)contextInfo {
if(!error){
NSLog(@"Photo saved to library!");
} else{
NSLog(@"Saving failed :(");
}
}
selectedImage не ноль.
Метод photoSaved объявлен в .h
Я также пытался с @selector (photoSaved :) и @selector (photoSaved).
В чем проблема?
