UIButton删除所有目标操作

呼叫 removeTarget:action:forControlEvents:

目标-C

[someControl removeTarget:nil 
                   action:NULL 
         forControlEvents:UIControlEventAllEvents];

Swift 2号

button.removeTarget(nil, action: nil, forControlEvents: .AllEvents)

button.removeTarget(nil, action: nil, for: .allEvents)

@Swift 2中的项目回复:

button.removeTarget(nil, action: nil, forControlEvents: .AllEvents)

button.removeTarget(nil, action: nil, for: .allEvents)

注意:Swift没有 NULL nil 而且看起来效果不错。

Swift 3、4、5:

btnCancel.removeTarget(nil, action: nil, forControlEvents: UIControlEvents.AllEvents)

actionButton.removeTarget(nil, action: nil, forControlEvents: .AllEvents)

Swift 3和;4:

actionButton.removeTarget(nil, action: nil, for: .allEvents)

目标C:

[actionButton removeTarget: nil action: NULL forControlEvents: UIControlEventAllEvents];

- removeTarget:action:forControlEvents:

此方法停止向指定的目标对象传递事件。

1. 有效对象

2. 指定 无

   目标c:

   [_myButton removeTarget:  //any validObject (or) nil
                 action:nil
       forControlEvents:UIControlEventAllEvents]; 
   

   银行代码:

   myButton.removeTarget(*validObject or nil*, action:nil, forControlEvents:UIControlEvents.AllEvents)
