سؤال
I'd like to do an action if someone touches a predeclared UILabel
, something like:
if (label is touched) {
my actions;
}
Is there a method/way to do that?

You could use a gesture recognizer:
- (void)someSetupMethod {
// ...
label.userInteractionEnabled = YES;
UITapGestureRecognizer *tapGesture = \
[[UITapGestureRecognizer alloc]
initWithTarget:self action:@selector(didTapLabelWithGesture:)];
[label addGestureRecognizer:tapGesture];
[tapGesture release];
}
- (void)didTapLabelWithGesture:(UITapGestureRecognizer *)tapGesture {
// ...
}

By default, UILabel
isn't configured to accept touch input. However, if you use a UIButton
instead and set it to have a custom appearance, you can make it look like a (single-line) label and have it respond to touch events.
You can subclass it and override the touch methods. You probably want to override touchesEnded:withEvent:
.
Or just use a UIButton.
You need to make sure userinteractionenabled is set to YES and then you can override the touchesBegan:withEvent:
Just Add A category for UILabel Class and add your method to it.
