在iOS8之后UIActionSheet (以及它们各自的 delegate protocols)已经被弃用，用UIAlertController来代替，一下是iOS8之前和之后的2种做法：
double version = [[UIDevice currentDevice].systemVersion doubleValue];//判定系统版本。
if(version>=8.0f){
UIAlertController *alertController = [UIAlertControlleralertControllerWithTitle:@"提示"message:nilpreferredStyle:UIAlertControllerStyleActionSheet];
[alertControlleraddAction:[UIAlertActionactionWithTitle:@"确定"style:UIAlertActionStyleDefaulthandler:^(UIAlertAction * _Nonnull action) {
NSLog(@"确定");
}]];
[alertControlleraddAction:[UIAlertActionactionWithTitle:@"取消"style:UIAlertActionStyleDestructivehandler:^(UIAlertAction * _Nonnull action) {
NSLog(@"取消");
}]];
[selfpresentViewController:alertControlleranimated:YEScompletion:nil];
}else{
#pragma clang diagnostic push
#pragma clang diagnostic ignored "-Wdeprecated-declarations"
UIActionSheet *sheetView = [[UIActionSheetalloc]initWithTitle:@"提示"delegate:selfcancelButtonTitle:nildestructiveButtonTitle:nilotherButtonTitles:@"确定",@"取消", nil];
#pragma clang diagnostic pop
sheetView.actionSheetStyle = UIActionSheetStyleDefault;
[sheetView showInView:self.view];
}
#pragma mark actionSheet_delegate 点击事件
