Uigesturerecognizer gesture Manipulation

The Uigesturerecognizer class, used to detect and identify gestures used by the user when using the device, defines the basic behavior of all gestures. The following is the Uigesturerecognizer subclass, yo about handling specific user gesture behavior.

Click Gestures

*singletap=[[UITapGestureRecognizer alloc]initwithtarget:self Action: @selector (Singletap:)];    [Self.view Addgesturerecognizer:singletap]; // Click event -(void) Singletap: (UITapGestureRecognizer *) tapgestrue{    NSLog (@ "  Click ");

Double-click Gestures

*doubletap=[[UITapGestureRecognizer alloc]initwithtarget:self Action: @selector (Doubletap:)];    doubletap.numberoftapsrequired=2;    [Self.view Addgesturerecognizer:doubletap];     // Difference Click Double tap gesture     [Singletap Requiregesturerecognizertofail:doubletap]; // Double click on Event -(void) Doubletap: (UITapGestureRecognizer *) taggestrue{    NSLog (@ " Double- click ");}

Swipe gestures

Uiswipegesturerecognizer *swipegesture=[[Uiswipegesturerecognizer alloc]initwithtarget:self Action: @selector ( Swipe:)];     // set swipe direction, default to right    Swipegesture.direction=uiswipegesturerecognizerdirectiondown;     [Self.view addgesturerecognizer:swipegesture]; // Swipe event -(void) Swipe: (Uiswipegesturerecognizer *) swipegesture{    NSLog (@ " Swipe gesture ");}

Translation

Uipangesturerecognizer *pangesture=[[Uipangesturerecognizer alloc]initwithtarget:self Action: @selector (pan:)] ;    [Self.view addgesturerecognizer:pangesture];    // Pan Event -(void) Pan: (Uipangesturerecognizer *) pan{    cgpointpoint =[pan LocationInView:self.view];    NSLog (@ "%@", Nsstringfromcgpoint (point));}

Long-Press gestures

Uilongpressgesturerecognizer *longpressgesture=[[Uilongpressgesturerecognizer alloc]initwithtarget:self Action: @selector (longpress:)]; Longpressgesture.minimumpressduration=2; [Self.view addgesturerecognizer:longpressgesture];//long-press gesture event-(void) Longpress: (Uilongpressgesturerecognizer *) longpress{//Long Press to leave the call once, so you need to set the gesture State    if(longpress.state==uigesturerecognizerstateended) {        return; } NSLog (@"Long press for more than two seconds");} 

Rotate gestures

Uirotationgesturerecognizer *rotation=[[Uirotationgesturerecognizer alloc]initwithtarget:self action:@ Selector (rotation:)];    [Self.view addgesturerecognizer:rotation]; // Rotation Event -(void) Rotation: (Uirotationgesturerecognizer *) rotation{    //  Obtained angle    float degree=rotation.rotation* (m_pi) According    to the rotational radian; NSLog (@ "%f", Degree);}
