自定义UIAlertController
1:显示alert，点击过到指定时间，dissMiss Alert
2:显示alert，点击过到指定时间，dissMiss Alert 后，继续执行block内容
class Utils :NSObject{
static var alert: UIAlertController!
// 消息提示框
public static func notifyUser(title: String, message: String, timeToDissapear: Int) -> Void
{
alert = UIAlertController(title: title,
message: message,
preferredStyle: UIAlertControllerStyle.alert)
let cancelAction = UIAlertAction(title: “确定”,
style: .cancel, handler: {
action in
return
})
alert.addAction(cancelAction)
UIApplication.shared.keyWindow?.rootViewController!
.present(alert, animated: true,completion: nil)
//定时关闭
_ = Timer.scheduledTimer(timeInterval: Double(timeToDissapear), target: self, selector: #selector(Utils.dismissAlert), userInfo: nil, repeats: false)
}
@objc static func dismissAlert()
{
// Dismiss the alert from here
alert.dismiss(animated: true, completion: nil)
}
typealias ZZWandBlock = (() -> Void)
var andBlock : ZZWandBlock?
// 消息提示框
func notifyUserB(title: String, message: String, timeToDissapear: Int,_ block: @escaping (() -> Void)) -> Void
{
andBlock = block
Utils.alert = UIAlertController(title: title,
message: message,
preferredStyle: UIAlertControllerStyle.alert)
let cancelAction = UIAlertAction(title: NSLocalizedString(“BUTTON_OK”, comment: “确定”),
style: .cancel, handler: {
action in
block()
return
})
Utils.alert.addAction(cancelAction)
UIApplication.shared.keyWindow?.rootViewController!
.present(Utils.alert, animated: true,completion: nil)
// self.present(alert, animated: true) {
//
// }
//定时关闭
_ = Timer.scheduledTimer(timeInterval: Double(timeToDissapear), target: self, selector: #selector(Utils.dismissAlertB), userInfo: nil, repeats: false)
}
@objc func dismissAlertB()
{
// Dismiss the alert from here
if Utils.alert.isBeingDismissed {
}else{
Utils.alert.dismiss(animated: true){
self.andBlock!()
}
}
}
}
用法：Utils.notifyUser(title: “tips”, message: “请连接”, timeToDissapear: 3)
Utils().notifyUserB(title: “信息”, message: “状态”, timeToDissapear: 3, {
print(“jbcdksbck”)
})
