Solution to uilongpressgesturerecognizer execution twice

Recently, I used ios sdk 3.2 to write the map module more than three years ago. I long pressed the pin on the map and found that two pins were inserted in an inexplicable point. Check whether the current SDK is used to determine uilongpressgesturerecognizer. State in the selector method bound to uilongpressgesturerecognizer. The following is a solution to the problem:

// Long-pressed map event-(void) longpressgesturerecognizeraction :( uilongpressgesturerecognizer *) gesturerecognizer {If (gesturerecognizer. state = uigesturerecognizerstateended) {nslog (@ "Long press ended");} else {nslog (@ "Long press detected. "); // ooxx .....}}
