Question

我需要一个带图像的UIAlert。据我所知，UIAlertView没有一个构造函数来获取image.So现在我需要创建customAlertView。但我不知道怎么做。是customAlertView将是UIAlertView的子类，所以它采取UIAlertView的委托方法或什么???我搜索了很多但没有找到customAlertView的实现。我是cocoa触摸的新手框架，并没有自己的专业知识。所以有人帮助我.plz给我一些实现，而不仅仅是逻辑。等待你的答案。

试试这个：

    NSString *title = [NSString stringWithFormat:@"YOUR TITLE"];
    NSString *alertMessage = [NSString stringWithFormat:@"YOUR MESSAGE"];
    NSString *button1 = [NSString stringWithFormat:@"your button 1"];
    NSString *button2 = [NSString stringWithFormat:@"your button 2"];

    UIAlertView *alert = [[UIAlertView alloc] initWithTitle:title message:alertMessage delegate:self cancelButtonTitle:button1 otherButtonTitles:button2, nil];

    UIImage *alertImage = [UIImage imageNamed:@"your image"];

    UIImageView *backgroundImageView = [[UIImageView alloc] initWithImage:alertImage];
    backgroundImageView.frame = CGRectMake(0, 0, 282, 130);
    backgroundImageView.contentMode = UIViewContentModeScaleToFill;

    [alert addSubview:backgroundImageView];
    [alert sendSubviewToBack:backgroundImageView];
    [alert show];
    [alert release];
