pass parameter to UITapGestureRecognizer [duplicate]

Answer 1

Pass the sender,

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

Answer 2

You can extend a UITapGestureRecognizer for holding 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);

}
