Pass parameter UITapGestureRecognizer

Question

I created a dynamic view of UIimage and and UITapGestureRecognizer to see how it looks

 UIImageView *image = [[UIImageView alloc ] initWithFrame:CGRectMake(x, 0, 200, 150)]; NSString *ImageURL = [str objectForKey:@"imageLink"]; NSData *imageData = [NSData dataWithContentsOfURL:[NSURL URLWithString:ImageURL]]; image.image = [UIImage imageWithData:imageData]; UITapGestureRecognizer *singleTap = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(tapDetected:)]; singleTap.numberOfTapsRequired = 1; image.userInteractionEnabled = YES; [image addGestureRecognizer:singleTap]; [documentory addSubview:image]; 

and my method of action like this

 -(void)tapDetected:(UIGestureRecognizer *)recognizer{ NSLog(@"single Tap on imageview"); } 

I want to pass tapDetected string parameters, can someone tell me how to do this, thank you very much

Answer 1

You can extend the UITapGestureRecognizer to store more data:

 // MYTapGestureRecognizer.h @interface MYTapGestureRecognizer : UITapGestureRecognizer @property (nonatomic, strong) NSString *data; @end // MYTapGestureRecognizer.m @implementation MYTapGestureRecognizer @end // ===================== .... MYTapGestureRecognizer *singleTap = [[MYTapGestureRecognizer alloc] initWithTarget:self action:@selector(tapDetected:)]; singleTap.data = @"Hello"; ..... // ==================== -(void)tapDetected:(UITapGestureRecognizer *)tapRecognizer { MYTapGestureRecognizer *tap = (MYTapGestureRecognizer *)tapRecognizer; NSLog(@"data : %@", tap.data); } 

Answer 2

Tell the sender

 - (void)tapDetected:(UIGestureRecognizer *)sender { NSLog(@"%@", sender.view); // imageview }
