简单delegate（省略版本）

设置delegate

.h文件

#import <UIKit/UIKit.h>

@protocol PauseViewDelegate <NSObject>

- (void) Touchstart;

- (void) Touchprevious;

- (void) Touchnext;

- (void) Touchback;

@end

@interface PauseView : UIView

{

}

@property (nonatomic ,assign)id delegate;

@end

.m文件

- (void)touchesEnded:(NSSet *)touches withEvent:(UIEvent *)event

{

    [super touchesEnded:toucheswithEvent:event];

    UITouch *touch = [touches anyObject];

    CGPoint touchPoint = [touch locationInView:self];

    NSLog(@"end %f==%f",touchPoint.x,touchPoint.y);

    

    [self.delegateTouchpause];

 }

实现delegate

.h文件

没做处理

.m文件

#import "PauseView.h"

@interface ViewController ()

{

   

}

 @property (nonatomic ,strong)PauseView *pauseView;

 @end

 

- (void)viewDidLoad {

    [superviewDidLoad];

    self.pauseView=[[PauseViewalloc]initWithFrame:[UIScreenmainScreen].bounds];

    self.pauseView.backgroundColor=[UIColorclearColor];

    self.pauseView.delegate =self;

    [self.viewaddSubview:self.pauseView];

    

}

//PauseViewDelegate

- (void)Touchpause

{

 NSLog(@"Touchpause");

}
