ios - 第一个 UIButton 触发同一 View 的另一个 UIbutton 事件

Question

我已经快速创建了两个 UIButton 并以编程方式添加了操作。当我尝试点击第一个按钮时，两个按钮 Action 都会被触发。但是当我点击第二个按钮时，没有触发任何事件。

var btnSort = UIButton(frame: CGRectMake(2, 74, 140, 26))
btnSort.setTitle("SORT", forState: UIControlState.Normal)
btnSort.backgroundColor = UIColor.grayColor()
btnSort.tag=10
btnSort.addTarget(self, action: Selector("showSortTbl:"), forControlEvents: UIControlEvents.TouchUpInside)
self.view.addSubview(btnSort)



var btnFilter = UIButton(frame: CGRectMake(140+16+2, 74, 140, 26))
btnFilter.backgroundColor = UIColor.redColor()
btnFilter.tag=11
btnFilter.setTitle("FILTER", forState: UIControlState.Normal)
btnSort.addTarget(self, action: Selector("showFilterTbl:"), forControlEvents: UIControlEvents.TouchUpInside)
self.view.addSubview(btnFilter)



func showSortTbl(sender: UIButton){
    var btnSendTag :UIButton = sender
    if(btnSendTag.tag == 10){

println("show sort")

    }

}


func showFilterTbl(sender: UIButton){

    var btnSendTag :UIButton = sender
    if(btnSendTag.tag == 11){

        println("show filter")

    }

}

改变这一行

btnSort.addTarget(self, action: Selector("showFilterTbl:"), forControlEvents: UIControlEvents.TouchUpInside)

到

btnFilter.addTarget(self, action: Selector("showFilterTbl:"), forControlEvents: UIControlEvents.TouchUpInside)
