ios触屏事件指南

这篇文章主要给大家总结介绍了2种实现ios触屏事件的方法，简单实用，有需要的小伙伴可以参考下。

复制代码代码如下:

//在一个函数里面（初始化等）里面添加要识别触摸事件的范围
    infoView=[[UIView alloc] initWithFrame:CGRectMake(20, 100,220, 280)];//范围，出了这个范围就检测不到触摸了
    infoView.backgroundColor=[UIColor blueColor];
    infoView.alpha=0.6;
    [self.view addSubview:infoView];
    /******************监视手势控制*****************///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];
//触摸事件的实现函数
//滑动事件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：

复制代码代码如下:

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());
