如何使用HSImageSidebarView将.png UIImage文件添加到白色背景？

我尝试创建UIImageView，然后在侧边栏上显示，但不幸的是，应用程序崩溃了NSException。如果这些图像文件是UIImage而非UIImageView，则有关如何在侧边栏上为图像文件添加白色背景的任何想法。

Answer 1

您将尝试此代码在nib上添加一个scrollview并在viewdidload

上设置其内容

CGFloat x = 20;
for (int i = 0;i<[playerScores count];i++) {
    UIView *view = [[UIView alloc] initWithFrame:CGRectMake(x, 10, 60, 60)];
    view.backgroundColor=[UIColor blueColor];
    NSString *text = [NSString stringWithFormat:[playerScores objectAtIndex:i]];
    [view setText:text];

    [yardsScrollView addSubview:view];
    [myLabel release];
    x = x+125;
}

PlayersScore是一个NSMutable数组，其中包含许多文本，例如您想要多少视图。

@ objc-强迫

You will need to loop through the subviews to find whether it is of kind UIImage or UIImageView by this:
id object; 
if([object isKindOfClass:[UIImage Class]]) {
     //Do whatever u want to here by creating a new imageView on the top of this image
     //Something like this:
UIImage *image =(UIImage*)object;
UIImageView *imgView=[[uiimageview alloc]initwithimage:image];

//Now perform the background view operations on imgView i.e. instance of UIImageView.
}

//Hope it works.
