1 屏幕触控实现(单击 双击)
[self becomeFirstResponder];//允许多点互动self.view.multipleTouchEnabled=TRUE;
实现事件部分
#PRagmamark-#pragmamark touch
- (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event{//触摸开始}- (void)touchesMoved:(NSSet *)touches withEvent:(UIEvent *)event{//移动}- (void)touchesEnded:(NSSet *)touches withEvent:(UIEvent *)event{//结束UITouch *atouch=[touches anyObject];if(atouch.tapCount>=2)
{//双击}elseif(atouch.tapCount==1)
{//单击}
}- (void)touchesCancelled:(NSSet *)touches withEvent:(UIEvent *)event{
}
2 手势识别(UIlabel 点击事件实现)
//设置图片的点击事件UITapGestureRecognizer *recongnizer=[[UITapGestureRecognizer alloc]initWithTarget:self action:@selector(handleTapFrom:)];
recongnizer.numberOfTapsRequired=1;
self.img.userInteractionEnabled=YES;
[self.img addGestureRecognizer:recongnizer];
}-(void)handleTapFrom:(UITapGestureRecognizer *)recognizer{
[self updateDisplayValuesWithTip:@"tap"tapCount:1touchCount:1];
}
3 屏幕晃动实现
//AppDelegate 中实现- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
application.applicationSupportsShakeToEdit=YES;
}//或者代码中实现[[UIApplication sharedApplication] setApplicationSupportsShakeToEdit:YES];//ViewController 中实现下面方法- (void)motionBegan:(UIEventSubtype)motion withEvent:(UIEvent *)eventNS_AVAILABLE_IOS(3_0);
{
}- (void)motionEnded:(UIEventSubtype)motion withEvent:(UIEvent *)eventNS_AVAILABLE_IOS(3_0)
{if(event.subtype ==UIEventSubtypeMotionShake) {//摇一摇 行为}
}- (void)motionCancelled:(UIEventSubtype)motion withEvent:(UIEvent *)eventNS_AVAILABLE_IOS(3_0)
{
}
4 图片滑动换页
UISwipeGestureRecognizer *recognizer;
self.img.userInteractionEnabled=YES;
recognizer=[[UISwipeGestureRecognizer alloc] initWithTarget:self action:@selector(handleSwipeFrom:)];
[recognizer setDirection:(UISwipeGestureRecognizerDirectionRight)];
[[self img] addGestureRecognizer:recognizer];
}-(void)handleSwipeFrom:(UISwipeGestureRecognizer *)recognizer {
NSLog(@"Swipe received.");if(recognizer.direction==UISwipeGestureRecognizerDirectionRight) {
NSLog(@"swipe down");
[UIView beginAnimations:nil context:nil];
[UIView setAnimationDuration:2.0f];
[UIView setAnimationCurve:UIViewAnimationCurveEaseInOut];
[UIView setAnimationRepeatAutoreverses:NO];
[UIView setAnimationTransition:UIViewAnimationTransitionCurlUp forView:self.view cache:YES];//界面变化部分//........[UIView commitAnimations];
}
}
