我如何在 swift 中将 uiview (xib) 显示为警报视图 [英] How can i present uiview (xib) as alert view in swift

问题描述

我想将我的 xib 显示为警报视图.在 xib 中，主视图将是半透明的，这将防止用户在警报视图启动时点击后台中的任何其他内容.我没有在 xib 中使用视图控制器.

I want to present the my xib as the alert view. In the xib main view is going to be semi-transparent, which will prevent users from tapping on anything else in the background while the alert view is up. I am not using the view controller in xib.

推荐答案

1.获取 XIB 文件对象.

1.Fetch the XIB file object.

let alert = NSBundle.mainBundle().loadNibNamed("Alert", owner: self, options: nil).last as! UIView     

2.编写便捷方法.

static func showAlert() {
    let windows = UIApplication.sharedApplication().windows
    let lastWindow = windows.last
    alert.frame = UIScreen.mainScreen().bounds
    lastWindow?.addSubview(alert)
}

static func removeAlert() {
    alert.removeFromSuperview()
}

3.调用方法.

//showing alert
ClassName.showAlert()

//remove alert
ClassName.removeAlert()
