Here is a code sample:
这是一个代码示例：
NSString *path = [[NSBundle mainBundle] pathForResource: @"YourPLIST" ofType: @"plist"];
NSDictionary *dict = [NSDictionary dictionaryWithContentsOfFile: path];
id obj = [dict objectForKey: @"YourKey"];

NSBundle* mainBundle = [NSBundle mainBundle];?

// Reads the value of the custom key I added to the Info.plist
NSString *value = [mainBundle objectForInfoDictionaryKey:@"key"];
//Log the value
NSLog(@"Value = %@", value);
// Get the value for the "Bundle version" from the Info.plist
[mainBundle objectForInfoDictionaryKey:@"CFBundleVersion"];
// Get the bundle identifier
[mainBundle bundleIdentifier];

NSURL *url = [[NSBundle mainBundle] URLForResource:@"YOURPLIST" withExtension:@"plist"];
NSArray *playDictionariesArray = [[NSArray alloc ] initWithContentsOfURL:url];
NSLog(@"Here is the Dict %@",playDictionariesArray);
or you can use following also
或者你也可以使用以下
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentsDirectory = [paths objectAtIndex:0];
NSString *path = [documentsDirectory stringByAppendingPathComponent:@"Sample.plist"];

Get from plist is very simple.
从 plist 获取非常简单。
NSString *path = [[NSBundle mainBundle] pathForResource:@"SaveTags" ofType:@"plist"];
if (path) {
NSDictionary *root = [NSDictionary dictionaryWithContentsOfFile:path];
}
If you want to add something to a plist, maybe you can find the answer here: How to write data in plist?
如果你想在 plist 中添加一些东西，也许你可以在这里找到答案： 如何在 plist 中写入数据？
But if you only want save some message in you app, NSUserDefaults is the better way.
但是如果你只想在你的应用程序中保存一些消息，NSUserDefaults 是更好的方法。

You can not do this. Any Bundle wether it is iOS or Mac OS is readonly, you can only read to it and you can't create files, write or do anything with the files in a bundle. This is part of the Security features of apple. You can use the NSDocumentsDirectory to writr and read your stuff you need for your app
你不可以做这个。任何捆绑包无论是 iOS 还是 Mac OS 都是只读的，您只能读取它，而不能创建文件、写入或对捆绑包中的文件执行任何操作。这是苹果安全功能的一部分。您可以使用 NSDocumentsDirectory 来编写和阅读您的应用程序所需的内容
