Question

I wanted to detect the user touch release and if the user is holding it, the code down below

works, but dont tell me if i’m holding ( touch and hold and not releasing ) the touch…

please help me fix that

[imageview setUserInteractionEnabled:YES];
UITapGestureRecognizer *singleTap =  [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(holdAction:)];
[singleTap setNumberOfTapsRequired:1];
[imageview addGestureRecognizer:singleTap];



- (void)holdAction:(UIGestureRecognizer *)holdRecognizer
{
    if (holdRecognizer.state == UIGestureRecognizerStateBegan) {


       NSLog(@"Holding Correctly. Release when ready.");

    } else if (holdRecognizer.state == UIGestureRecognizerStateEnded)
    {
       NSLog(@"You let go!");
    }
}

Answer 1

Do it with the -touchesBegan:withEvent: and -touchesEnded:withEvent: methods.

-(void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event
{
    self.isHolding = YES;
}

-(void)touchesEnded:(NSSet *)touches withEvent:(UIEvent *)event
{
    self.isHolding = NO;
}

Where self.isHolding is a @property (nonatomic, assign) BOOL isHolding;
Note: In those methods you may need to perform additional check if the touches have started over a particular view and also where they have ended.
UPDATE: Change your code accordingly:

[imageview setUserInteractionEnabled:YES];
UILongPressGestureRecognizer *longPress =  [[UILongPressGestureRecognizer alloc] initWithTarget:self action:@selector(holdAction:)];
[imageview addGestureRecognizer:longPress];



- (void)holdAction:(UILongPressGestureRecognizer *)holdRecognizer
{
    if (holdRecognizer.state == UIGestureRecognizerStateBegan) {


       NSLog(@"Holding Correctly. Release when ready.");

    } else if (holdRecognizer.state == UIGestureRecognizerStateEnded)
    {
       NSLog(@"You let go!");
    }
}
