iOS开篇——UI之UIActionSheet

UIActionSheet在iOS8.3之后已不建议使用。 可以使用

UIAlertController+UIAlertControllerStyleActionSheet获得同样的效果

创建UIActionSheet

    UIActionSheet * as = [[UIActionSheet alloc]initWithTitle:@"选择一个英雄" delegate:self cancelButtonTitle:@"取消" destructiveButtonTitle:@"德玛" otherButtonTitles:@"琴女", nil];

//设置样式
    as.actionSheetStyle = UIActionSheetStyleBlackOpaque;

实现协议方法 

- (void)actionSheet:(UIActionSheet *)actionSheet clickedButtonAtIndex:(NSInteger)buttonIndex{
    switch (buttonIndex) {
        case 0:
            NSLog(@"这是第0个");
            break;
        case 1:
            NSLog(@"这是第1个");
            break;
        default:
            break;
    }
}

使用UIAlertController+UIAlertControllerStyleActionSheet实现

    UIAlertController * ac = [UIAlertController alertControllerWithTitle:@"选择一个英雄" message:@"没事" preferredStyle:UIAlertControllerStyleActionSheet];
    [ac addAction:[UIAlertAction actionWithTitle:@"取消" style:UIAlertActionStyleDefault handler:^(UIAlertAction * _Nonnull action) {
        NSLog(@"取消");
    }]];
    
    [ac addAction:[UIAlertAction actionWithTitle:@"德玛" style:UIAlertActionStyleDefault handler:^(UIAlertAction * _Nonnull action) {
        NSLog(@"德玛");
    }]];
    
    [self presentViewController:ac animated:YES completion:nil];
