我可以在自定义 UIAlertView 中添加 UIImageView 吗？

Question

我已经有一个自定义 UIAlertView，我想在其中添加 UIImageView 以添加自定义 UIAlertView。

我已经添加了带有数组的 UIImageView 并开始对其进行动画处理，但它不起作用。如果你愿意，我可以发布代码。

请尽快帮助我。我被卡住了:(

这是代码

- (id)initWithImage:(UIImage *)image text:(NSString *)text
{

    //CGSize imageSize = self.backgroundImage.size;
    CGRect frame = [[UIScreen mainScreen] bounds];

    width = frame.size.width; 
    height = frame.size.height;

    if (self = [super init])
    {



        loadtext = [[UILabel alloc]initWithFrame:CGRectZero];
        loadtext.textColor = [UIColor blackColor];
        loadtext.backgroundColor = [UIColor whiteColor];
        [self addSubview:loadtext];

        //Create the first status image and the indicator view
        UIImage *statusImage = [UIImage imageNamed:@"status1.png"];
        activityImageView = [[UIImageView alloc] 
                                          initWithImage:statusImage];


        //Add more images which will be used for the animation
        activityImageView.animationImages = [NSArray arrayWithObjects:
                                             [UIImage imageNamed:@"status1.png"],
                                             [UIImage imageNamed:@"status2.png"],
                                             [UIImage imageNamed:@"status3.png"],
                                             [UIImage imageNamed:@"status4.png"],
                                             [UIImage imageNamed:@"status5.png"],
                                             [UIImage imageNamed:@"status6.png"],
                                             [UIImage imageNamed:@"status7.png"],
                                             nil];


        //Set the duration of the animation (play with it
        //until it looks nice for you)
        activityImageView.animationDuration = 1.0;


        //Position the activity image view somewhere in 
        //the middle of your current view
        activityImageView.frame = CGRectZero;

        //Start the animation
        [activityImageView startAnimating];


        //Add your custom activity indicator to your current view
        [self addSubview:activityImageView];



        //self.backgroundImage = image;



    }
    return self;
}

- (void) layoutSubviews{
    //lblUserName.transform = CGAffineTransformMake;
    //[lblUserName sizeToFit];

    CGRect textRect = activityImageView.frame;
    textRect.origin.x = (CGRectGetWidth(self.bounds) - CGRectGetWidth(textRect))/2;
    textRect.origin.y = (CGRectGetHeight(self.bounds) - CGRectGetHeight(textRect))/2;
    textRect.origin.x -= 100.0;
    textRect.origin.y -= 60.0;
    textRect.size.height = 30;
    textRect.size.width = self.bounds.size.width - 50;

    activityImageView.frame = textRect;
}   

这段代码开始工作。但是现在这个 UIImageView 占据了我的整个屏幕并出现在 UIAlertView 前面。虽然我给出了 10px 高度和宽度。它显示相同。有人可以帮忙吗？

谢谢， 安克斯

Answer 1

是的，您可以在自定义警报视图中添加图像视图。不需要采用 UIView 自定义类，而是需要采用 UIImage-View &您可以使用图像视图属性。

Answer 2

将 activityImageView.frame = CGRectZero; 更改

为某个自定义框架。

例如：

activityImageView.frame = CGRectMake(0,0,100,100);
