Ios uicontrol状态的图像。未显示选定的
标题说明了一切。这是我的密码:Ios uicontrol状态的图像。未显示选定的,ios,swift,selected,uicontrolstate,Ios,Swift,Selected,Uicontrolstate,标题说明了一切。这是我的密码: func createCheckBoxButton(xPos: CGFloat, yPos: CGFloat, tag: Int) -> UIButton { var checkBox = UIButton(frame: CGRect(x: xPos, y: yPos, width: checkBoxSize, height: checkBoxSize)) checkBox.setBackgroundImage(UIImage(named:
func createCheckBoxButton(xPos: CGFloat, yPos: CGFloat, tag: Int) -> UIButton {
var checkBox = UIButton(frame: CGRect(x: xPos, y: yPos, width: checkBoxSize, height: checkBoxSize))
checkBox.setBackgroundImage(UIImage(named: "checkbox_inactive"), forState: UIControlState.Normal)
checkBox.setBackgroundImage(UIImage(named: "checkbox_pressed"), forState: UIControlState.Highlighted)
checkBox.setBackgroundImage(UIImage(named: "checkbox_active"), forState: UIControlState.Selected)
checkBox.tag = tag
checkBox.contentMode = .ScaleAspectFit
checkBox.addTarget(self, action: "processButton:", forControlEvents: UIControlEvents.TouchUpInside)
return checkBox
}
当按下我的按钮时,有一个被调用的函数:
func processButton(sender: UIButton) {
if (answerViewArray[sender.tag].backgroundColor == UIColor.whiteColor()) {
answerViewArray[sender.tag].backgroundColor = myColor.pinky()
} else {
answerViewArray[sender.tag].backgroundColor = UIColor.whiteColor()
}
let tag = answerButtonsArray[sender.tag]
answer.buttonPressed(tag)
}
当我启动应用程序时,会出现复选框\u inactive
图像。当我按下并保持按下时,会出现复选框\u pressed
图像。但当我松开鼠标时,会再次出现复选框\u inactive
,而不是复选框\u active
我还尝试了使用UIImageView
,这实际上是对我来说最好的解决方案。我将复选框设置为UIImageView
,并在常规视图的顶部放置一个不可见的视图,以便我可以在任何地方单击。但是当我按下我的不可见视图时,UIImageView
就消失了
代码如下:
func createCheckBoxButton(xPos: CGFloat, yPos: CGFloat) -> UIImageView {
var checkBox = UIImageView(frame: CGRect(x: xPos, y: yPos, width: checkBoxSize, height: checkBoxSize))
checkBox.image = UIImage(named: "checkbox_inactive")
checkBox.contentMode = .ScaleAspectFit
return checkBox
}
以下是名为:
func processButton(sender: UIButton) {
if (answerViewArray[sender.tag].backgroundColor == UIColor.whiteColor()) {
answerViewArray[sender.tag].backgroundColor = myColor.pinky()
checkBoxArray[sender.tag].image = UIImage(named: "checkbox-active")
} else {
answerViewArray[sender.tag].backgroundColor = UIColor.whiteColor()
checkBoxArray[sender.tag].image = UIImage(named: "checkbox-inactive")
}
let tag = answerButtonsArray[sender.tag]
answer.buttonPressed(tag)
}
若要在释放按钮时激活“显示”复选框,应为按下的按钮设置“选中=真” 因此,您的函数应该如下所示:
func processButton(sender: UIButton) {
// If button not selected
if(sender.selected==false){
sender.selected = true;
}
else{ // If button already selected
sender.selected = false;
}
// Do your other stuff
}
请原谅我的无知,我对斯威夫特很陌生:D@Magohamoth对于您的第二个问题,我不能肯定地说什么,因为您的代码并没有完全满足调试的所有要求,但若您不想创建类似于复选框的视图,那个么UIButton是最好的方法。
