iOS - UUID代抛出一个奇怪的异常 [英] iOS - UUID generation throwing a strange exception

问题描述

我正在尝试使用 https://github.com/gekitz / UIDevice-with-UniqueIdentifier-for-iOS-5 生成全局标识符。当我在git中尝试该示例时，它工作正常并正确显示标识符。但是，当我尝试将文件合并到一个新项目时，它不起作用！

I am trying to use https://github.com/gekitz/UIDevice-with-UniqueIdentifier-for-iOS-5 to generate a global identifier. When I try the sample in git it works fine and displays an identifier correctly. But when I try to incorporate the files into a new project it does not work!

我已经包含 -

#import "UIDevice+IdentifierAddition.h"

in my SampleAppDelegate.m，复制粘贴项目中的所有文件，并使用

in my SampleAppDelegate.m, copy pasted all files in the project, and am using

NSString *di = [[UIDevice currentDevice] uniqueGlobalDeviceIdentifier];

。我在uniqueGlobalDeviceIdentifier方法的第一行放了一个断点，但它永远不会到达！我错过了什么吗？

in the init method. I put a breakpoint on the first line of uniqueGlobalDeviceIdentifier method, but it is never reached! Am I missing something?

编辑：

异常 -

Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[UIDevice uniqueGlobalDeviceIdentifier]: unrecognized selector sent to instance 0x68170c0'

推荐答案

看起来像 UIDevice + IdentifierAddition.m 未编译。要检查/添加它：

It looks like UIDevice+IdentifierAddition.m is not being compiled. To check / add it:

1. 点击Xcode左侧导航器中的项目。


2. 选择应用目标。


3. 选择'Build Phases'选项卡。


4. 打开'Compile Sources'。


5. 检查 UIDevice + IdentifierAddition.m 是否存在。如果没有，则单击+，选择它并单击添加。

1. Click on the project in the navigator on the left in Xcode.
2. Select the app target.
3. Select the 'Build Phases' tab.
4. Open up 'Compile Sources'.
5. Check that UIDevice+IdentifierAddition.m is in there. If not, then click the '+', select it and click add.

该异常指向此作为修复，因为它说的是 UIDevice 上没有方法，名为 uniqueGlobalDeviceIdentifier ，由类别添加。

The exception points to this as the fix because it's saying that there is no method on UIDevice called uniqueGlobalDeviceIdentifier, which is added by the category.
