IOS触摸与手势
一：触摸
//触摸开始
- (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event{
//UITouch的常用属性
UITouch *touch = [touches anyObject];
//点击的次数
NSLog(@"tap count: %ld", touch.tapCount);
//触摸的阶段
NSLog(@"phase: %ld", touch.phase);
//在视图上的位置坐标
CGPoint point = [touch locationInView:self];
NSLog(@"location in view: %@", NSStringFromCGPoint(point));
CGPoint windowPoint = [touch locationInView:[UIApplication sharedApplication].keyWindow];
NSLog(@"location in window: %@", NSStringFromCGPoint(windowPoint));
//在视图上前一个点的坐标
CGPoint prePoint = [touch previousLocationInView:self];
NSLog(@"previous location in view: %@", NSStringFromCGPoint(prePoint));
}
//触摸移动
- (void)touchesMoved:(NSSet *)touches withEvent:(UIEvent *)event
{
// NSLog(@"触摸移动");
//UITouch的常用属性
UITouch *touch = [touches anyObject];
//在视图上的位置坐标
CGPoint point = [touch locationInView:self];
NSLog(@"location in view: %@", NSStringFromCGPoint(point));
//在视图上前一个点的坐标
CGPoint prePoint = [touch previousLocationInView:self];
NSLog(@"previous location in view: %@", NSStringFromCGPoint(prePoint));
}
//触摸结束
- (void)touchesEnded:(NSSet *)touches withEvent:(UIEvent *)event{
NSLog(@"触摸结束");
}
//触摸被取消
- (void)touchesCancelled:(NSSet *)touches withEvent:(UIEvent *)event
{
NSLog(@"触摸被取消");
}
- (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event
{
UITouch *touch = [touches anyObject];
if (touch.tapCount == 1) {
//单击
//[self singleTap];
[self performSelector:@selector(singleTap)
withObject:nil
afterDelay:0.2];
} else if (touch.tapCount == 2) {
//双击
[NSObject cancelPreviousPerformRequestsWithTarget:self
selector:@selector(singleTap)
object:nil];
[self doubleTap];
}
}
- (void)singleTap
{
NSLog(@"单击");
}
- (void)doubleTap
{
NSLog(@"双击");
}
//运动事件
- (void)motionBegan:(UIEventSubtype)motion withEvent:(UIEvent *)event
{
NSLog(@"摇一摇开始");
}
- (void)motionEnded:(UIEventSubtype)motion withEvent:(UIEvent *)event
{
NSLog(@"摇一摇结束");
}
- (void)motionCancelled:(UIEventSubtype)motion withEvent:(UIEvent *)event
{
}
//远程控制事件
- (void)remoteControlReceivedWithEvent:(UIEvent *)event
{
}
二：手势
//1.轻击
UITapGestureRecognizer *tap = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(tapAction:)];
tap.numberOfTapsRequired = 2;
tap.numberOfTouchesRequired = 3;
[self.view addGestureRecognizer:tap];
//2.捏合
UIPinchGestureRecognizer *pinch = [[UIPinchGestureRecognizer alloc] initWithTarget:self action:@selector(pinchAction:)];
[self.view addGestureRecognizer:pinch];
//3.拖移
//UISwipeGestureRecognizer
UIPanGestureRecognizer *pan = [[UIPanGestureRecognizer alloc] initWithTarget:self action:@selector(panAction)];
[self.view addGestureRecognizer:pan];
//
//4.轻扫
UISwipeGestureRecognizer *swipe = [[UISwipeGestureRecognizer alloc] initWithTarget:self action:@selector(swipeAction)];
[self.view addGestureRecognizer:swipe];
//5.长按
//UILongPressGestureRecognizer
UILongPressGestureRecognizer *press = [[UILongPressGestureRecognizer alloc] initWithTarget:self action:@selector(pressAction:)];
[self.view addGestureRecognizer:press];
//6.旋转
//UIRotationGestureRecognizer
}
- (void)tapAction:(UITapGestureRecognizer *)sender
{
NSLog(@"tap");
}
- (void)pinchAction:(UIPinchGestureRecognizer *)sender
{
NSLog(@"捏");
}
- (void)panAction
{
NSLog(@"pan");
}
- (void)swipeAction
{
NSLog(@"swipe");
}
- (void)pressAction:(UILongPressGestureRecognizer *)sender
{
NSLog(@"press");
if(sender.state == UIGestureRecognizerStateBegan)
{
NSLog(@"开始");
} else if (sender.state == UIGestureRecognizerStateChanged)
{
NSLog(@"移动");
} else if (sender.state == UIGestureRecognizerStateEnded)
{
NSLog(@"结束");
}
}
