NSFileManager在文档文件夹中

Question

i am trying to zip a file into a subfolder in my iphone app.

 NSArray *path = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
  NSString *dir = [path objectAtIndex:0];

             NSString *storeunzipfiles = [dir stringByAppendingPathComponent:@"/MyFolder"]; 
 if (![[NSFileManager defaultManager] fileExistsAtPath:storeunzipfiles])
   [[NSFileManager defaultManager] createDirectoryAtPath:storeunzipfiles attributes:nil]; //Create folder

ok now i created the folder. What i want to do is to del all the files in the folder before i unzip my file. but i am not getting it.

        NSFileManager *filemgr;


           filemgr = [NSFileManager defaultManager];

           [filemgr removeItemAtPath: @"/MyFolder" handler: nil];

   // warning: 'NSFileManager' may not respond to '-removeItemAtPath:handler:'

      }     

      }

lastly, unzip to subfolder.

   if ([zip UnzipFileTo:storeunzipfiles overWrite:YES]) {...

ok i got a warning msg...

whats the method to load the files in the subfolder? is this right?

NSString *docpath = [documentsDirectory stringByAppendingPathComponent:@"/MyFolder/Data.plist"];     ?

thks in advance

Answer 1

There is no -removeItemAtPath:handler: method. You want -removeItemAtPath:error: instead.

Answer 2

No,

You can use method

- (NSArray *)contentsOfDirectoryAtPath:(NSString *)path error:(NSError **)error

this will return a NSarray object that contains Name of File contains in given folder. after that u can remove easily. example

NSarray *array=[filemanager contentsOfDirectoryAtPath:@"/MyFolder" error:nil];
for(int i=0;i<[array count];i++)
{
    [filemanager removeItemAtPath:[@"/MyFolder" stringByAppendingPathComponent:[array objectAtIndex:i]] error:nil];
}

so folder will be empty
