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
#PRagma mark-
#pragma mark 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
}
else if(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:1 touchCount: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 *)event NS_AVAILABLE_IOS(3_0);
{
}
- (void)motionEnded:(UIEventSubtype)motion withEvent:(UIEvent *)event NS_AVAILABLE_IOS(3_0)
{
if (event.subtype == UIEventSubtypeMotionShake) {
//摇一摇 行为
}
}
- (void)motionCancelled:(UIEventSubtype)motion withEvent:(UIEvent *)event NS_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];
}
}
