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

   代碼如下:

  //在一個函數裡面(初始化等)裡面添加要識別觸摸事件的範圍

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

  infoView.backgroundColor=[UIColor blueColor];

  infoView.alpha=0.6;

  [self.view addSubview:infoView];

  /******************監視手勢控制*****************///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 的實現函數

  //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:

  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());

  以上所述就是本文的全部內容了,希望大家能夠喜歡。
