Question

我的iPhone项目中有一张图片。这是一个PNG，我可以在Interface Builder中设置背景，但我想以编程方式执行此操作。

NSLog(@"Before %@", myEasterEgg);
uiImageBackground.backgroundColor = [UIColor purpleColor];
myEasterEgg = [myEasterEgg stringByAppendingString:@"5"];
NSLog(@"After %@", myEasterEgg);
if (CFStringCompare((CFStringRef)myEasterEgg, (CFStringRef)@"52235", 1) == 0) {
    myEasterEgg = @"";
    uiImageBackground.backgroundColor = [UIColor clearColor];
    [uiImageBackground setImage:[UIImage imageNamed:@"dock.png"]];
    uiImageBackground.image = image;
}
[myEasterEgg retain];
NSLog(@"After %@", myEasterEgg);

以上是我的按钮中的代码。它不显示dock.png文件。

更新。我修改了代码，因为如果声明总是会执行，而且它仍然没有加载图像。修改后的代码！

NSLog(@"Before %@", myEasterEgg);
uiImageBackground.backgroundColor = [UIColor purpleColor];
myEasterEgg = [myEasterEgg stringByAppendingString:@"5"];
NSLog(@"After %@", myEasterEgg);
    myEasterEgg = @"";
    uiImageBackground.backgroundColor = [UIColor clearColor];
    [uiImageBackground setImage:[UIImage imageNamed:@"dock.png"]];
    uiImageBackground.image = image;
[myEasterEgg retain];
NSLog(@"After %@", myEasterEgg);

Answer 1

代码应该有效。（1）测试从未通过，因此永远不会调用加载图像或（2）dock.png文件未正确添加到项目中，以便将其加载到应用程序包中。

如何在资源文件夹中加载图像？
