如何在目标 c 中给出吐司消息

Question

我正在尝试在用户登录时提供 Toast 消息，并且用户将能够看到一条 Toast 消息，上面写着“新数据可用”和下方的按钮，上面写着“下载和取消”。但是当下载来时，它的字体以粗体出现。请让我知道怎么做默认情况下，我使这个看起来正常

代码如下：

 UIAlertView* alert = [[UIAlertView alloc]initWithTitle:msg message:@""delegate:self cancelButtonTitle:@"Download" otherButtonTitles: @"Ignore",nil];

我需要下载应该在吐司消息中以普通字体出现。

我有一个简单的代码来提供 Toast。

- (void) ShowAlert:(NSString *)Message {
    UIAlertController * alert=[UIAlertController alertControllerWithTitle:nil
                                                                  message:@""
                                                           preferredStyle:UIAlertControllerStyleAlert];
    UIView *firstSubview = alert.view.subviews.firstObject;
    UIView *alertContentView = firstSubview.subviews.firstObject;
    for (UIView *subSubView in alertContentView.subviews) { 
        subSubView.backgroundColor = [UIColor colorWithRed:141/255.0f green:0/255.0f blue:254/255.0f alpha:1.0f];
    }
    NSMutableAttributedString *AS = [[NSMutableAttributedString alloc] initWithString:Message];
    [AS addAttribute: NSForegroundColorAttributeName value: [UIColor whiteColor] range: NSMakeRange(0,AS.length)];
    [alert setValue:AS forKey:@"attributedTitle"];
    [self presentViewController:alert animated:YES completion:nil];
    dispatch_after(dispatch_time(DISPATCH_TIME_NOW, (int64_t)(2.0 * NSEC_PER_SEC)), dispatch_get_main_queue(), ^{
        [alert dismissViewControllerAnimated:YES completion:^{
        }];
    });
}

用

[self ShowAlert:@"Please Enter Your Good Name."];
