iOS 檔案的操作

標籤：

NSString *path = NSHomeDirectory();

上面的代碼得到的是應用程式目錄的路徑，在該目錄下有三個檔案夾：Documents、Library、temp以及一個.app包！

該目錄下就是應用程式的沙箱，應用程式只能訪問該目錄下的檔案夾！！！

 

 

請參考下面的例子：

1、

NSString *path1 = NSHomeDirectory();

 

NSLog(@"path1:%@", path1);

path1:/Users/yuanjun/Library/Application Support/iPhone Simulator/4.2/Applications/172DB70A-145B-4575-A31E-D501AC6EA830

2、

NSString *path2 = [NSSearchPathForDirectoriesInDomains(NSCachesDirectory, NSUserDomainMask, YES) lastObject];

 

NSLog(@"path2:%@", path2);

path2:/Users/yuanjun/Library/Application Support/iPhone Simulator/4.2/Applications/172DB70A-145B-4575-A31E-D501AC6EA830/Library/Caches

3、

NSString *path3 = [NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES) lastObject];

 

NSLog(@"path3:%@", path3);

path3:/Users/yuanjun/Library/Application Support/iPhone Simulator/4.2/Applications/172DB70A-145B-4575-A31E-D501AC6EA830/Documents

4、

NSString *path4 = [NSHomeDirectory() stringByAppendingPathComponent:@"Documents"];

 

NSLog(@"path4:%@", path4);

path4:/Users/yuanjun/Library/Application Support/iPhone Simulator/4.2/Applications/172DB70A-145B-4575-A31E-D501AC6EA830/Documents

5、

NSString *path5 = [NSHomeDirectory() stringByAppendingPathComponent:@"Library"];

 

NSLog(@"path5:%@", path5);

path5:/Users/yuanjun/Library/Application Support/iPhone Simulator/4.2/Applications/172DB70A-145B-4575-A31E-D501AC6EA830/Library

6、

NSString *path6 = [NSHomeDirectory() stringByAppendingPathComponent:@"temp"];

 

NSLog(@"path6:%@", path6);

path6:/Users/yuanjun/Library/Application Support/iPhone Simulator/4.2/Applications/172DB70A-145B-4575-A31E-D501AC6EA830/temp
