ios触屏事件指南

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());
