iOS　UIActionSheet的基本使用

Posted 2020-06-24

NS_CLASS_DEPRECATED_ios(2_0, 8_3, "UIActionSheet is deprecated. Use UIAlertController with a preferredStyle of UIAlertControllerStyleActionSheet instead") __TVOS_PROHIBITED

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 = [UIAlertController alertControllerWithTitle:@"提示" message:nil preferredStyle:UIAlertControllerStyleActionSheet];

     [alertController addAction:[UIAlertAction actionWithTitle:@"确定" style:UIAlertActionStyleDefault handler:^(UIAlertAction * _Nonnull action) {

         NSLog(@"确定");

     }]];

     [alertController addAction:[UIAlertAction actionWithTitle:@"取消" style:UIAlertActionStyleDestructive handler:^(UIAlertAction * _Nonnull action) {

         NSLog(@"取消");

     }]];

     [self presentViewController:alertController animated:YES completion:nil];

 

 }else{

     #pragma clang diagnostic push

     #pragma clang diagnostic ignored "-Wdeprecated-declarations"

     UIActionSheet *sheetView = [[UIActionSheet alloc] initWithTitle:@"提示" delegate:self cancelButtonTitle:nil destructiveButtonTitle:nil otherButtonTitles:@"确定",@"取消", nil];

     #pragma clang diagnostic pop

     sheetView.actionSheetStyle =  UIActionSheetStyleDefault;

     [sheetView showInView:self.view];

     }

#pragma mark actionSheet_delegate 点击事件

- (void)actionSheet:(UIActionSheet *)actionSheet clickedButtonAtIndex:(NSInteger)buttonIndex NS_DEPRECATED_IOS(2_0, 8_3) __TVOS_PROHIBITED{

    NSLog(@"%@",@(buttonIndex));

}
