1,简单的应用(同时按钮响应Handler使用闭包函数)
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 | import UIKit class VIEwController : UIVIEwController , UIActionSheetDelegate { overrIDe func vIEwDIDLoad() { super .vIEwDIDLoad() } vIEwDIDAppear(animated: Bool ){ .vIEwDIDAppear(animated) let alertController = UIAlertController (Title: "系统提示" "您确定要离开hangge.com吗?" UIAlertControllerStyle . Alert ) cancelAction = UIAlertAction "取消" UIAlertActionStyle Cancel nil ) okAction = "好的" Default in print ( "点击了确定" ) }) alertController.addAction(cancelAction) alertController.addAction(okAction) self .presentVIEwController(alertController,animated: true ) } dIDReceiveMemoryWarning() { .dIDReceiveMemoryWarning() // dispose of any resources that can be recreated. } } |
@H_404_258@2,除了d出,还可以使用从底部向上滑出的样式
(注意:如果上拉菜单中有“取消”按钮的话,那么它永远都会出现在菜单的底部,不管添加的次序是如何) @H_419_265@
var "保存或删除数据" "删除数据将不可恢复" preferredStyle: ActionSheet ) ) deleteAction = "删除" Destructive ) archiveAction = "保存" ) alertController.addAction(cancelAction) alertController.addAction(deleteAction) alertController.addAction(archiveAction) ) |
3,按钮使用“告警”样式(文字颜色变红,用来来警示用户) @H_419_265@
4,添加任意数量文本输入框(比如可以用来实现个登陆框) @H_419_265@
