Question

I have an UIImageViews with userInteractionEnabled, and i want to know with image i currently tap. What i should do to know that? I have a poster wall and class for that ThumbPosterModel there i have all poster information with i want to pass through.

So my code is:

for (ThumbPosterModel *tPoster in _thumbsPosterStack) {

    UIImageView *imageView = [[UIImageView alloc] initWithImage:tPoster.thumb];
    imageView.userInteractionEnabled = YES;
    imageView.frame = CGRectMake(i, imageView.frame.origin.y, imageView.frame.size.width, imageView.frame.size.height);

    [_posterWallScrollView addSubview:imageView];

    UITapGestureRecognizer *tap =
    [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(imageTapped:)];
    [imageView addGestureRecognizer:tap];
}

And then i have:

-(IBAction)imageTapped:(id)sender {
    //something do here, but know i don't know what.
}

Should i subclass UIImageView that should contains all ThumbPosterModel params? I don’t think it is good idea, but i can’t figure any other solution.

Answer 1

Ok this is very simple just add tag proprty of each image with appropriate and distinct value other then 0 and use that proprty to identify the image 🙂

Happy Coding 🙂
