使用XCode 6 / Swift在iOS 7.1中显示的图像 [英] Images not showing in iOS 7.1 with XCode 6 / Swift

问题描述

我有这个ObjC代码：

I have this ObjC code:

[self.myButton setBackgroundImage:[UIImage imageNamed:[NSString stringWithFormat:@"%@-button", self.myObject.name]]
                         forState:UIControlStateNormal];

这适用于以下组合：

• XCode 5，iOS 7.1


• XCode 6，iOS 7.1


• XCode 6，iOS 8

但是，当我将项目的一个单独的类移植到Swift时 - 这个类与此代码中发生的任何事情无关 - 图像执行不适用于iOS 7.1的XCode 6。它适用于XCode 6和iOS 8.

But when I port one single class of the project to Swift -- a class which is unrelated to anything that is happening in this code -- the images do not display in XCode 6 for iOS 7.1. It does work with XCode 6 and iOS 8.

我完成了将整个项目移植到Swift，现在代码如下：

I finished porting the entire project to Swift, so now the code looks like:

self.myButton.setBackgroundImage(
    UIImage(named:self.myObject.name + "-button"),
    forState: UIControlState.Normal
)

在iOS 7.1上它仍然不满意。仍然没有图像。 （虽然自定义图标有效。）是的，我知道这只是测试版软件，它可能只是一个bug ......？但我只是想知道是否有人有解决方案或洞察力。

And it's still unhappy on iOS 7.1. Still no images. (The custom icon works, though.) Yes, I know this is just beta software, and it's probably just a bug ... ? But I'm just wondering if anyone has a solution or insight.

我一周前才开始使用XCode和ObjC（惊喜！ObjC现已弃用！），所以它可能是我遗漏了一些东西，但由于它在ObjC和Swift + iOS8中工作，似乎它可能是一个bug。

I only started using XCode and ObjC about a week ago (surprise! ObjC is now deprecated!), so it could be that I am missing something, but since it works in ObjC, and in Swift+iOS8, it seems like it's probably a bug.

推荐答案

我设法通过不使用资产库来存储我的图像来解决这个问题。

I've managed to overcome this by not using Asset Libraries to store my images.

使用旧式命名将图像添加到项目中，例如 Image.png 和 [e-mail] ，然后在文件名中加载它们没有任何扩展名，如下：

Add your images to the project using the "old style naming", like Image.png and [e-mail], then load them without any extensions in the filename, as such:

let myImage = UIImage(named:"Image")
