UIButton按住动作和释放动作

我想创build一个可以按下的UIButton，当它按下时，它会调用一次“hold down”操作。 当它被释放时，调用“暂停释放”动作。

此代码无法正常工作，因为触摸可以在button内移动，并且事件不会以正确的顺序触发

[button handleControlEvent:UIControlEventTouchDown withBlock:^{ [self performMomentaryAction:PXActionTypeTouchDown]; }]; [button handleControlEvent:UIControlEventTouchUpInside withBlock:^{ [self performMomentaryAction:PXActionTypeTouchUp]; }]; 

句柄控制事件是基于UIButton +模块实现的

Answer 1

尝试这个

  UIButton *aButton = [UIButton buttonWithType:UIButtonTypeRoundedRect]; aButton.frame = CGRectMake(xValue, yValue, 45, 45); [aButton addTarget:self action:@selector(holdDown) forControlEvents:UIControlEventTouchDown]; [aButton addTarget:self action:@selector(holdRelease) forControlEvents:UIControlEventTouchUpInside]; - (void)holdDown { NSLog(@"hold Down"); } - (void)holdRelease { NSLog(@"hold release"); } 

对于NSPratik的情况：你可以使用事件UIControlEventTouchUpOutside如果用户长按button，一段时间后，而不是释放手指，用户将他/她的手指移出button的界限。 只需添加一个事件。

  UIButton *aButton = [UIButton buttonWithType:UIButtonTypeRoundedRect]; aButton.frame = CGRectMake(xValue, yValue, 45, 45); [aButton addTarget:self action:@selector(holdDown) forControlEvents:UIControlEventTouchDown]; [aButton addTarget:self action:@selector(holdRelease) forControlEvents:UIControlEventTouchUpInside]; [aButton addTarget:self action:@selector(holdReleaseOutSide) forControlEvents:UIControlEventTouchUpOutside]; //add this for your case releasing the finger out side of the button's frame //add this method along with other methods - (void)holdReleaseOutSide { NSLog(@"hold release out side"); } 

Swift版本

  var aButton:UIButton = UIButton.buttonWithType(UIButtonType.Custom) as UIButton aButton.frame = CGRectMake(xValue,yValue, 45, 45) aButton.setTitle("aButton", forState: UIControlState.Normal) aButton.backgroundColor = UIColor.greenColor() aButton.addTarget(self, action: Selector("holdRelease:"), forControlEvents: UIControlEvents.TouchUpInside); aButton.addTarget(self, action: Selector("HoldDown:"), forControlEvents: UIControlEvents.TouchDown) self.addSubview(testButton) //target functions func HoldDown(sender:UIButton) { println("hold down") } func holdRelease(sender:UIButton) { println("hold release") } 

Answer 2

尝试这个

添加TouchDown，Touch Up Inside，Touch Up Outside事件到你的button

  -(IBAction)theTouchDown:(id)sender { timer = [NSTimer scheduledTimerWithTimeInterval:0.2 target:self selector:@selector(performFunctionality) userInfo:nil } -(IBAction)theTouchUpInside:(id)sender { [timer invalidate]; timer = nil; [self performFunctionality]; } -(IBAction)theTouchUpOutside:(id)sender { [timer invalidate]; timer = nil; } -(void)performFunctionality { //write your logic } 

Answer 3

我自己也面对这个问题，而且大多数情况下我们使用这些事件：

/ /这个事件工作正常，并触发

 [aButton addTarget:self action:@selector(holdDown) forControlEvents:UIControlEventTouchDown]; 

//这根本不会开火

 [aButton addTarget:self action:@selector(holdRelease) forControlEvents:UIControlEventTouchUpInside]; 

解：-

使用长按手势识别器： –

  UILongPressGestureRecognizer *btn_LongPress_gesture = [[UILongPressGestureRecognizer alloc] initWithTarget:self action:@selector(handleBtnLongPressgesture:)]; [aButton addGestureRecognizer:btn_LongPress_gesture]; 

手势的执行： –

 - (void)handleBtnLongPressgesture:(UILongPressGestureRecognizer *)recognizer{ //as you hold the button this would fire if (recognizer.state == UIGestureRecognizerStateBegan) { [self holdDown]; } //as you release the button this would fire if (recognizer.state == UIGestureRecognizerStateEnded) { [self holdRelease]; } }

  **in Swift 3.0,** btnPasswordShow.addTarget(self, action:#selector(btnShowPasswordClickHoldDown), for: .touchDown) btnPasswordShow.addTarget(self, action:#selector(btnShowPasswordClickRelease), for: .touchUpInside) func btnShowPasswordClickHoldDown(){ txtpassword.isSecureTextEntry = false } func btnShowPasswordClickRelease(){ txtpassword.isSecureTextEntry = true } 

Answer 5

从工具（窗格）拖动一个button，并右键单击它。一个列表将发生“find里面”，并点击并拖动文本前面的圆点，并将其移动到viewcontroller.h并定义一个名称，并在viewcontroller .m做到这一点。

nslog("clicked in"); 重复所有的操作，从列表中find适当的事件

Answer 6

您需要连接以下两个事件1.触摸下来，2.触摸它的IBAction方法。它将在Interface Builder中很有趣。 但是你也可以使用addTarget以编程的方式来实现：action：forControlEvents：
