最近产品抽风，想做许鲜网的那个小客服按钮，虽然没啥难度，但是我懒啊，哈哈，上度娘搞了一个，但是点击事件和拖动重复了，擦。干脆写一个吧，仅供参考。
话不多说，上代码：
- (UIButton *)panButton {
if (!_panButton) {
UIPanGestureRecognizer *panGesture = [[UIPanGestureRecognizer alloc] initWithTarget:self action:@selector(panAction:)];
_panButton = [[UIButton alloc] init];
_panButton.backgroundColor = [UIColor blueColor];
_panButton.layer.borderWidth = 1.f;
_panButton.layer.borderColor = [UIColor greenColor].CGColor;
[_panButton setTitle:@"清除缓存" forState:UIControlStateNormal];
_panButton.titleLabel.font = [UIFont systemFontOfSize:9];
[_panButton addTarget:self action:@selector(buttonAction:) forControlEvents:UIControlEventTouchUpInside];
[_panButton addGestureRecognizer:panGesture];
}
return _panButton;
}
- (void)panAction:(UIPanGestureRecognizer *)recognizer {
CGPoint translationPoint = [recognizer translationInView:self.view];
CGPoint center = recognizer.view.center;
recognizer.view.center = CGPointMake(center.x + translationPoint.x, center.y + translationPoint.y);
[recognizer setTranslation:CGPointZero inView:self.view];
}
-(void)buttonAction:(UIButton *)sender
{
NSLog(@"烦人，点我干啥~");
}
