1. Distinguish between click and double clicking events

-(void) addtaphandler{    //Click Recognizer    uitapgesturerecognizer* singlerecognizer;    Singlerecognizer = [[UITapGestureRecognizer alloc] initwithtarget:self action: @selector (Singletapacton:)];    /**     *  click */    singlerecognizer.numberoftapsrequired = 1;//click        to add a gesture monitor to the view;    Self.feedview Addgesturerecognizer:singlerecognizer];            Double-click the Recognizer    uitapgesturerecognizer* Doublerecognizer;    Doublerecognizer = [[UITapGestureRecognizer alloc] initwithtarget:self action: @selector (Doubletapacton)];                /**     *  Double-click */    doublerecognizer.numberoftapsrequired = 2;               Add a gesture monitor to the view;    [Self.feedview Addgesturerecognizer:doublerecognizer];            [Singlerecognizer Requiregesturerecognizertofail:doublerecognizer];}

2. Uilongpressgesturerecognizer to perform two-time problems

-(void) Handlelongpress: (uilongpressgesturerecognizer*) Sender {     if (sender.state = = uigesturerecognizerstateended) {        NSLog (@ "Long press Ended");    }    else {        NSLog (@ "Long press detected.");}    }
