introduced=2.0, deprecated=8.3 早已废弃 还是拥抱 UIAlertController 吧
创建UIActionSheet
let actionSheel = UIActionSheet()
actionSheel.addButtonWithTitle("取消")
actionSheel.addButtonWithTitle("选项一")
actionSheel.addButtonWithTitle("选项二")
actionSheel.cancelButtonIndex = 0
actionSheel.delegate = self
actionSheel.showInView(self.view)
实现代理 先遵守协议 UIActionSheetDelegate
func actionSheet(actionSheet: UIActionSheet, clickedButtonAtIndex buttonIndex: Int) {
print(actionSheet.buttonTitleAtIndex(buttonIndex)!)
if buttonIndex == actionSheet.cancelButtonIndex{
print("取消了!")
}else{
print("都说了已经废弃了!!!")
}
}
