iOS中NSBundle的使用
1、[NSBundle mainBundle],文件夹其实是Group,如左侧的树形文件管理器

Build之后,文件直接就复制到了根目录下,于是读取的方法,应该是这样:
| NSString*earth = [[NSBundlemainBundle] pathForResource:@"Brad Cox"ofType:@"png"]; | 
2、使用文件夹的时候,Build结果

依然使用同样的方法,不需要制定文件夹路径
//inDirectory参数可有可无
NSString *earth = [[NSBundle mainBundle] pathForResource:@"Matthijs" ofType:@"png" inDirectory:@"Images/MoreImages"]; NSString *earth = [[NSBundle mainBundle] pathForResource:@"Matthijs" ofType:@"png"];
编译之后,mainBundle的资源都是放到RootFolder下,所以,可以直接访问,不要指定内部路径
3、使用其他的Bundle

| NSString*resourceBundle = [[NSBundlemainBundle] pathForResource:@"Resources"ofType:@"bundle"];    NSLog(@"resourceBundle: %@", resourceBundle);    NSString*earth = [[NSBundlebundleWithPath:resourceBundle] pathForResource:@"Matthijs"ofType:@"jpg"inDirectory:@"Images/MoreImages"];    NSLog(@"path: %@", earth); | 
使用Custom bundle,访问内部的子文件夹,需要指定inDirectory参数,这个mainBundle不同,这是为何?
| 注意:Sincebundles other than the main bundle can have folders embedded inside them, to accessfiles inside folders of a bundle other than the main bundle it is best to use the pathForResource:ofType:inDirectory: method of NSBundleto explicitly specify the folder inwhich a specific file/resource exists. |
