ios touchscreen events guide

// in 1 Add a range of functions (initialization, etc.) to identify the touch event 

    infoView=[[UIView alloc] initWithFrame:CGRectMake(20, 100,220, 280)];// Range, beyond this range you can't detect touch 

    infoView.backgroundColor=[UIColor blueColor];

    infoView.alpha=0.6;

    [self.view addSubview:infoView];

    /****************** Monitor gesture control *****************/// There is up and down left and right, I only used left and right, on the bet off. 

    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];

// Touch events   Implementation function of 

// Sliding event 1

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

    // If I slide to the left 

    if(recognizer.direction==UISwipeGestureRecognizerDirectionLeft) {

        NSLog(@"**************** The left slide ****************");

    }

    // If I slide to the right 

    if(recognizer.direction==UISwipeGestureRecognizerDirectionRight) {

        NSLog(@"**************** Slide to the right ****************");       

    }

   if (recognizer.direction==UISwipeGestureRecognizerDirectionDown){

       NSLog(@"**************** The sliding ****************");

    }

    if (recognizer.direction==UISwipeGestureRecognizerDirectionUp){

      NSLog(@"**************** Slides up ****************");

   }

}

Method 2:

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());
