在较早的osx版本中，从xcassets加载带有imageNamed的NSImage会崩溃 [英] Loading NSImage with imageNamed from xcassets crash in older osx versions

问题描述

因此，我有一个xcassets，在许多应用程序之间共享.我正在装有MacOs Sierra的Mac Mini中使用Xcode8进行开发.如果我在开发机器中编译并运行，那根本没有问题.但是，当我尝试在装有OSX Mavericks的设备中运行它时，出现崩溃.这是报告中的痕迹

如果我从xcassets中删除图像并将其单独"包含在应用程序的捆绑软件中-通过将其拖放到应用程序的项目导航器中，就可以正常加载.但是我想尽可能避免这种情况，因为在一个xcassets中共享图像更加干净.

有什么想法或想法吗?预先感谢.

解决方案

我可以按照

So, I have an xcassets that is shared amongst quite a few apps. I'm developing with Xcode8 in a Mac Mini with MacOs Sierra installed in it. If I compile and run in the development machine, there's no issue at all. However, when I try to run it in a device with OSX Mavericks I get a crash. Here's the trace in the report

Thread 0 Crashed:: Dispatch queue: com.apple.main-thread

If I remove the image from the xcassets and include it "individually" in the app's bundle -by dropping it to the app's project navigator- it loads just fine. But I'd like to avoid this if possible, as it's cleaner to have shared images in just one xcassets.

Any thoughts or ideas? Thanks in advance.

解决方案

I could bypass this error by following this workaround provided by Apple for iOS 7 devices:

To work around this issue, update the deployment target to iOS 8.0 or higher, or add a single image to the asset catalog that has at least five attributes specified across the image set, such as: scale (1x, 2x, 3x) idiom (add iPad,iPhone, and a universal asset) direction (left to right, right to left) width/height class (any & compact, and so forth) memory (add a 1 GB asset) graphics (add a Metal 1v2 asset) It is not necessary to use the image in your code or to add all of these attributes.

Here's how this dummy imageset looks like:
