NSDocumentDirectory में निदेशकों की सूची कैसे प्राप्त करें?

Question

मैं के रूप में

if (![tbxCreateFolder.text isEqualToString:@""]) { 
NSArray *arrPaths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES); 
NSString *documentsDirectoryStr = [arrPaths objectAtIndex:0]; // Get documents folder 
NSString *dataPath = [documentsDirectoryStr stringByAppendingPathComponent:[NSString stringWithFormat:@"/%@",tbxCreateFolder.text]]; 

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

    NSError* error; 
    if([[NSFileManager defaultManager] createDirectoryAtPath:dataPath withIntermediateDirectories:NO attributes:nil error:&error]){ 

     NSLog(@"success"); 
     //Perfrom DB Insertation 
    } 
    else 
    { 
     NSLog(@"[%@] ERROR: attempting to write create MyFolder directory", [self class]); 
     NSAssert(FALSE, @"Failed to create directory maybe out of disk space?"); 
    } 
} 

}

NSDocumentDirectory में कुछ निर्देशिका बनाया है अब मैं निर्देशिका है कि मैं दस्तावेज़ फ़ोल्डर में बनाया है की सूची प्राप्त करना चाहते हैं लेकिन प्रतिक्रिया

NSArray *arrPaths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES); 
NSString *basePathString = ([arrPaths count] > 0) ? [arrPaths objectAtIndex:0] : nil; 
NSLog(@"dirContents %@",basePathString); 

प्रतिक्रिया है :

Answer 1

यहां कोड है :

NSString *documentDirPath = [NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES) objectAtIndex:0]; 
// create directory named "test" 
[[NSFileManager defaultManager] createDirectoryAtPath:[documentDirPath stringByAppendingPathComponent:@"test"] withIntermediateDirectories:YES attributes:nil error:nil]; 
// retrieved all directories 
NSLog(@"%@", [[NSFileManager defaultManager] contentsOfDirectoryAtPath:documentDirPath error:nil]); 

NSArray *paths = [[NSFileManager defaultManager] contentsOfDirectoryAtPath:documentDirPath error:nil]; 
BOOL isDir = NO; 
for (NSString *path in paths) { 
    if ([fileManager fileExistsAtPath:path isDirectory:&isDir] && isDir) { 
     // path is directory 
    } 
} 

Answer 2

आप कोड के कुछ सरल लाइनों के साथ ऐसा कर सकते हैं

NSString *documentDirectoryPath = // Initialize with Documents path 
BOOL isDir = NO; 
NSFileManager *fileManager = [NSFileManager defaultManager]; 
NSArray *files = [fileManager contentsOfDirectoryAtPath:documentDirectoryPath error:NULL]; 

NSMutableArray *directoriesPaths = [NSMutableArray array]; 
for (NSString *filePath in files) { 
    if ([fileManager fileExistsAtPath:filePath isDirectory:&isDir] && isDir) { 
     [directoriesPaths addObject:filePath]; 
    } 
} 

NSLog(@"directories %@", directoriesPaths);

तुम हमेशा इस तरह -fileExistsAtPath:isDirectory: का उपयोग कर शीर्ष स्तर निर्देशिका की सामग्री की गणना कर सकते हैं:

NSFileManager *sharedFileManager = [NSFileManager defaultManager]; 
NSDirectoryEnumerator *files = [sharedFileManager enumeratorAtPath:yourPath]; 

for (NSString *path in files) { 
    BOOL isDirectory = NO; 
    [sharedFileManager fileExistsAtPath:path isDirectory:&isDirectory]; 
    if (isDirectory) { 
     // you found a directory, so do what you will with it 
    } 
}

इस कोशिश ,

NSArray *arrPath = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES); 
NSString *strFilePath = [[arrPath objectAtIndex:0] 
[[NSFileManager defaultManager] createDirectoryAtPath:[strFilePath stringByAppendingPathComponent:@"Sample"] withIntermediateDirectories:YES attributes:nil error:nil];
