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。

　　 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：

　　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;

　　GSHardwareK

　　}fuck = {header, key};

　　GSSendEvent(&fuck, GSGetPurpleApplicationPort());
