iOS应用目录

iOS程序都是在沙盒里面运行的，但是具体目录是咋样的呢？我写了个函数，list了所有的目录（包括文件）。咱们先来看一下：

[java]  view plain copy print ?

1. - (void)fileList:(NSString*)directory{  
2.     printf(">>>:%s\n",[directory UTF8String]);  
3.     NSError *error = nil;  
4.     NSFileManager * fileManager = [NSFileManager defaultManager];  
5.     NSArray *fileList = [fileManager contentsOfDirectoryAtPath:directory error:&error];   
6.     for (NSString* each in fileList) {  
7.         NSMutableString* path = [[NSMutableString alloc]initWithString:directory];  
8.         [path appendFormat:@"/%@",each];  
9.         [self fileList:path];  
10.         [path release];  
11.     }  
12. }  

调用：

[cpp]  view plain copy print ?

1. [self filelist:NSHomeDirectory()];  

来看一下打印结果：

分析：

虽然真机和模拟器有点不一样，但是其实是大同小异。NSHomeDirectory() 是获取沙盒的根目录，然后就是他下面的其他目录：Directory.app(Directory是我这个工程的名字)、Documents、Library、tmp，Library下面又有一些子目录等等。

Directory.app 是程序包目录，主要包含和程序相关的文件，Documents你可以自己放一些文件到这个目录下，Library 也是个重要的目录，比如你的NSUserDefaults的数据就是在Libarary下面的Preferences中，还有 Caches 等等，tmp看名字就知道是一个存放临时文件的。我们主要用到的还是documentd和library。

ios读取app文件和tmp文件

 

1、ios读取app文件

NSString *datafilepath = [[NSBundle mainBundle]pathForResource:@"book_list" ofType:@"rtf"]；

2、读取tmp内的文件

NSString *datafilepath = [NSString stringWithFormat:@"%@mydata.plist",NSTemporaryDirectory()];
