You can have addInvisibleButtons implementation as

UIButton *button = [UIButton buttonWithType:UIButtonTypeCustom];
[button setBackgroundColor:[UIColor clearColor]];
[button addTarget:self action:@selector(buttonHandler) forControlEvents:UIControlEventAllEvents];
[button setTitle:@"point" forState:UIControlStateNormal];
button.frame = CGRectMake(0.0, 0.0, 40.0, 40.0);
self.imageView.userInteractionEnabled = YES;
[self.imageView addSubview:button];

If you want to have UIButton as completely invisible then you need to remove a line [button setTitle:@"point" forState:UIControlStateNormal]; since it use to show text on UIButton which make it visible.

This may resolve your issue.
