ios觸屏事件指南

這篇文章主要給大家總結(jié)介紹了2種實現(xiàn)ios觸屏事件的方法，簡單實用，有需要的小伙伴可以參考下。

//在一個函數(shù)里面（初始化等）里面添加要識別觸摸事件的范圍

    infoView=[[UIView alloc] initWithFrame:CGRectMake(20, 100,220, 280)];//范圍，出了這個范圍就檢測不到觸摸了

    infoView.backgroundColor=[UIColor blueColor];

    infoView.alpha=0.6;

    [self.view addSubview:infoView];

    /******************監(jiān)視手勢控制*****************///有上下左右，我只用到了左右，上下注掉了。

    UISwipeGestureRecognizer *recognizer;

    recognizer = [[UISwipeGestureRecognizer alloc] initWithTarget:self action:@selector(handleSwipeFrom:)];

    [recognizer setDirection:(UISwipeGestureRecognizerDirectionRight)];

    [infoView addGestureRecognizer:recognizer];

//    recognizer = [[UISwipeGestureRecognizer alloc] initWithTarget:self action:@selector(handleSwipeFrom:)];

//    [recognizer setDirection:(UISwipeGestureRecognizerDirectionUp)];

//    [self.view addGestureRecognizer:recognizer];

//    recognizer = [[UISwipeGestureRecognizer alloc] initWithTarget:self action:@selector(handleSwipeFrom:)];

//    [recognizer setDirection:(UISwipeGestureRecognizerDirectionDown)];

//    [self.view addGestureRecognizer:recognizer];

    recognizer = [[UISwipeGestureRecognizer alloc] initWithTarget:self action:@selector(handleSwipeFrom:)];

    [recognizer setDirection:(UISwipeGestureRecognizerDirectionLeft)];

    [infoView addGestureRecognizer:recognizer];

//觸摸事件 的實現(xiàn)函數(shù)

//滑動事件1

-(void)handleSwipeFrom:(UISwipeGestureRecognizer *)recognizer{

    //如果往左滑

    if(recognizer.direction==UISwipeGestureRecognizerDirectionLeft) {

        NSLog(@"****************向左滑****************");

    }

    //如果往右滑

    if(recognizer.direction==UISwipeGestureRecognizerDirectionRight) {

        NSLog(@"****************向右滑****************");       

    }

   if (recognizer.direction==UISwipeGestureRecognizerDirectionDown){

       NSLog(@"****************向下滑****************");

    }

    if (recognizer.direction==UISwipeGestureRecognizerDirectionUp){

      NSLog(@"****************向上滑****************");

   }

}

方法二：

復(fù)制代碼代碼如下:

GSEventRecord header;     

GSHardwareKeyInfo key = {0,0,0,0,1,{'a'},1,{'a'},0,0,0,0};     

memset(&header, 0, sizeof(header));     

header.type = kGSEventKeyDown;     

header.infoSize = sizeof(GSHardwareKeyInfo);     

header.timestamp = mach_absolute_time();     

struct     

{     

    GSEventRecord header1;     

    GSHardwareKeyInfo key1;     

}fuck = {header, key};     

GSSendEvent(&fuck, GSGetPurpleApplicationPort());    

    GSEventRecord header;  

    GSHardwareKeyInfo key = {0,0,0,0,1,{'a'},1,{'a'},0,0,0,0};  

    memset(&header, 0, sizeof(header));  

    header.type = kGSEventKeyDown;  

    header.infoSize = sizeof(GSHardwareKeyInfo);  

    header.timestamp = mach_absolute_time();  

    struct  

    {  

        GSEventRecord header1;  

        GSHardwareKeyInfo key1;  

    }fuck = {header, key};  

    GSSendEvent(&fuck, GSGetPurpleApplicationPort());
