introduced=2.0, deprecated=9.0 ios9已经废弃 建议使用UIAlertController
创建AlertView
let alertView = UIAlertView()
alertView.title = "温馨提示"
alertView.message = "UIAlertView已经废弃,不要再执着了"
alertView.addButtonWithTitle("取消")
alertView.addButtonWithTitle("确定")
alertView.cancelButtonIndex = 0
alertView.delegate = self
alertView.show()
执行代理 : 先添加代理UIAlertViewDelegate
func alertView(alertView: UIAlertView, clickedButtonAtIndex buttonIndex: Int) {
if buttonIndex == alertView.cancelButtonIndex{
print("取消了")
}else{
print("骚年,放弃吧")
}
}
