我创建了一个活动窗口函数,它有3个输入,
一切正常,除了需要删除子视图的部分。如果在主视图控制器上运行相同的功能。它工作正常。就在我把它移到NSObject时,它没有。请帮忙
class UIDesignFunction: NSObject {
func progressBarDisplayer(msg:String, indicator:Bool, view:UIView) {
var activityIndicator = UIActivityIndicatorView()
var strLabel = UILabel()
var msgFrame = UIView()
if indicator{
//println(msg)
strLabel = UILabel(frame: CGRect(x: 50, y: 0, width: 200, height: 50))
strLabel.text = msg
strLabel.textColor = UIColor.whiteColor()
msgFrame = UIView(frame: CGRect(x: view.frame.midX - 90, y: view.frame.midY - 25 , width: 180, height: 50))
msgFrame.layer.cornerRadius = 15
msgFrame.backgroundColor = UIColor(white: 0, alpha: 0.7)
activityIndicator = UIActivityIndicatorView(activityIndicatorStyle: UIActivityIndicatorViewStyle.White)
activityIndicator.frame = CGRect(x: 0, y: 0, width: 50, height: 50)
activityIndicator.startAnimating()
msgFrame.addSubview(activityIndicator)
UIApplication.sharedApplication().beginIgnoringInteractionEvents()
msgFrame.addSubview(strLabel)
view.addSubview(msgFrame)
}else{
UIApplication.sharedApplication().endIgnoringInteractionEvents()
msgFrame.removeFromSuperview()
}
}

将变量移出函数,如下所示
class UIDesignFunction: NSObject {
var activityIndicator = UIActivityIndicatorView()
var strLabel = UILabel()
var msgFrame = UIView()
func progressBarDisplayer(msg:String, indicator:Bool, view:UIView) {
if indicator{
//println(msg)
strLabel = UILabel(frame: CGRect(x: 50, y: 0, width: 200, height: 50))
strLabel.text = msg
strLabel.textColor = UIColor.whiteColor()
msgFrame = UIView(frame: CGRect(x: view.frame.midX - 90, y: view.frame.midY - 25 , width: 180, height: 50))
msgFrame.layer.cornerRadius = 15
msgFrame.backgroundColor = UIColor(white: 0, alpha: 0.7)
activityIndicator = UIActivityIndicatorView(activityIndicatorStyle: UIActivityIndicatorViewStyle.White)
activityIndicator.frame = CGRect(x: 0, y: 0, width: 50, height: 50)
activityIndicator.startAnimating()
msgFrame.addSubview(activityIndicator)
UIApplication.sharedApplication().beginIgnoringInteractionEvents()
msgFrame.addSubview(strLabel)
view.addSubview(msgFrame)
}else{
UIApplication.sharedApplication().endIgnoringInteractionEvents()
msgFrame.removeFromSuperview()
}
}
