我喜欢将UILongPressGestureRecognizer与UIPanGestureRecognizer结合使用.

UIPanGestureRecognizer应该从长按开始.有一个简单的方法吗？还是我真的要写自己的手势识别器？

我不喜欢在主屏幕上.你按下一个图标,一段时间后图标开始摇晃.之后我没有从屏幕上松开手指,我可以开始拖动手指下的图标.

我想在这个视图中移动一些UIView按钮.我可以这样做:

 - (void)viewDidLoad
    {
[button addTarget:self action:@selector(dragBegan:withEvent:) forControlEvents: UIControlEventTouchDown];
        [button addTarget:self action:@selector(dragMoving:withEvent:) forControlEvents: UIControlEventTouchDragInside];
        [button addTarget:self action:@selector(dragEnded:withEvent:) forControlEvents: UIControlEventTouchUpInside | UIControlEventTouchUpOutside];
}

.

    - (void)dragBegan:(UIControl *)c withEvent:ev {

    UITouch *touch = [[ev allTouches] anyObject];
    CGPoint touchPoint = [touch locationInView:self.view];

}

- (void)dragMoving:(UIControl *)c withEvent:ev {
    UITouch *touch = [[ev allTouches] anyObject];
    CGPoint touchPoint = [touch locationInView:self.view];
 //This is moving view to touchPoint
SimpleView.center = touchPoint;


}

- (void)dragEnded:(UIControl *)c withEvent:ev {

}

我怎么能只在那时移动它,如果我长按该按钮？
