Programmatically perform an action on UILabel touchUpInside?
I have a bunch of UILabels that I add through code and I want to perform a specific action for each if the user's finger touches up inside (muc开发者_运维问答h like UIButton's touchUpInside in IB). What is the best way of doing this?
The easiest way is probably to use UIButton instead of UILabel. A custom UIButton has no border and can look like a plain label, but handles the event tracking for you.
Otherwise, you must derive from UILabel and implement the UIResponder calls for touch handling.
You can use UITapGestureRecognizer to perform action over the label Fields.
Set the number of taps and touches on the UITapGestureRecognizer object.
[oneFingerTwoTaps setNumberOfTapsRequired:1];
[oneFingerTwoTaps setNumberOfTouchesRequired:1];
set user interaction of label field like
labelField.userInteractionEnabled = YES;
then add target method over the
UITapGestureRecognizer object.
