以編程方式創建目錄

我想在我的applicationSupportDirectory中創建一個目錄。我的理解是，applicationSupportDirectory不允許用戶查看其中的數據。這就是我選擇它的原因。但是，我在下面使用的代碼似乎失敗了，我不知道爲什麼。以編程方式創建目錄

有誰能告訴我我做錯了什麼嗎？謝謝！

NSArray *paths = NSSearchPathForDirectoriesInDomains(NSApplicationSupportDirectory, NSUserDomainMask, YES); 
NSString *applicationDirectory = [paths objectAtIndex:0]; // Get directory 
NSString *dataPath = [applicationDirectory stringByAppendingPathComponent:@"drawings"]; 

if (![[NSFileManager defaultManager] fileExistsAtPath:dataPath]){ 

NSError* error; 
if([[NSFileManager defaultManager] createDirectoryAtPath:dataPath withIntermediateDirectories:NO attributes:nil error:&error]) 
    ;// success 
else 
{ 
    NSLog(@"Failed"); 
} 
} 
}

請更改withIntermediateDirectories：是「YES」 – dhaya 2013-05-04 05:13:07

NSString *directoryName = @"drawing"; 

NSArray *paths = NSSearchPathForDirectoriesInDomains(NSApplicationSupportDirectory, NSUserDomainMask, YES); 

NSString *applicationDirectory = [paths objectAtIndex:0]; 
NSString *filePathAndDirectory = [applicationDirectory stringByAppendingPathComponent:directoryName]; 
NSError *error; 

if (![[NSFileManager defaultManager] createDirectoryAtPath:filePathAndDirectory 
           withIntermediateDirectories:YES 
               attributes:nil 
                error:&error]) 
{ 
    NSLog(@"Create directory error: %@", error); 
}

希望它會幫助你

試試這個，它爲我工作。

NSString* documentsPath = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, 
                   NSUserDomainMask, 
                   YES)[0]; 
NSString *folder = [documentsPath stringByAppendingPathComponent:@"foldername"]; 
NSFileManager *fileManager = [NSFileManager defaultManager]; 
NSError *error = nil; 
if (![fileManager fileExistsAtPath:folder]){ 
    [fileManager createDirectoryAtPath:folder 
      withIntermediateDirectories:YES 
          attributes:nil 
           error:&error]; 
}

這個答案其實是更好的。它只創建目錄，如果它不存在。豎起大拇指！ – Farini 2013-09-23 16:34:21

要創建Dirtectory

NSError *error; 
NSString *path = [NSHomeDirectory() stringByAppendingPathComponent:@"Library/Application Support/directoryname"]; 
NSLog(@"%@",path); 
if (![[NSFileManager defaultManager] fileExistsAtPath:path]) { 
    [[NSFileManager defaultManager] createDirectoryAtPath:path withIntermediateDirectories:YES attributes:nil error:&error]; 
    // Set do not backup attribute to whole folder 

}
