iOS：在代码中访问app-info.plist变量 [英] iOS: Access app-info.plist variables in code

问题描述

我正在开发一款Universal app&我希望在我的代码中访问存储在app-info.plist文件中的值。

I am working on a Universal app & would like to access the values stored in app-info.plist file in my code.

原因：我使用以下命令从故事板动态实例化UIViewController：

Reason: I instantiate a UIViewController dynamically from a storyboard using:

UIStoryboard* storyboard = [UIStoryboard storyboardWithName:@"MainStoryboard_iPhone" bundle:nil];
self = [storyboard instantiateViewControllerWithIdentifier:@"ExampleViewController"];

现在，上面的故事板名称@MainStoryboard_iPhone很难看。

Now, having the storyboard name @"MainStoryboard_iPhone" above is ugly.

我想做的事情如下：

UIStoryboard* storyboard = [UIStoryboard storyboardWithName:appInfo.mainStoryboardBaseNamePhone bundle:nil];
self = [storyboard instantiateViewControllerWithIdentifier:@"ExampleViewController"];

其中appInfo可能是app-info.plist中所有值的NSDictionary

where appInfo can perhaps be an NSDictionary of all values in app-info.plist

推荐答案

您项目的info.plist中的属性可通过以下方式直接访问...

Attributes from the info.plist for your project are directly accessible by the following...

[[NSBundle mainBundle] objectForInfoDictionaryKey:key_name];

例如，要获取版本号，您可以执行以下操作

For example to get the version number you might do the following

NSString *appVersion = [[NSBundle mainBundle] objectForInfoDictionaryKey:@"CFBundleVersion"];

现在有一个问题，版本号现在在info.plist中有两个属性 - 但是你明白了吗？如果您将info.plist视为源代码（右键单击info.plist - 选择Open As），您将看到可以使用的所有各种键名。

There is a gotcha in that the version number now has two attributes in the info.plist - but you get the idea? If you view your info.plist as source code (right click the info.plist - select Open As) then you will get to see all the various key names you can use.
