Objective-C folder full path

Too vague you set the task, so the answer will be in general:

Firstly, I remind you that in iOS there is such a thing as Sandboxing (Google Help), which, briefly, means that for any of your applications, access to the device’s file system is limited to several directories such as Documents/ and tmp/ (there are several , but it is really recommended to work with Documents and tmp/ ), that is, you can only access these directories, but you cannot access others.

Most likely you need to work with NSFileManager .

Try this (since you do not know what and where to output, I will show it for the temporary directory):

To see what is in the directory without passing its subdirectories:

 NSString *path = NSTemporaryDirectory(); NSArray *directoryContents = [NSFileManager.defaultManager subpathsOfDirectoryAtPath:path error:nil]; NSLog(@"Содержимое директории без заглядывания в поддиректории: %@", directoryContents); 

To see what is in the directory with regard to all subdirectories, their subdirectories, etc.:

 NSString *path = NSTemporaryDirectory(); NSLog(@" %@", [NSFileManager.defaultManager contentsOfDirectoryAtPath:path error:nil]); NSLog(@"Содержимое директории с проходом по всем поддиректориям: %@", directoryContents); 

NSTemporaryDirectory () - helps to get the path to the folder tmp/ your application. And here is a way to get the path to the Documents folder of your application:

 NSString *pathToDocumentsDirectory = [[[NSFileManager defaultManager] URLsForDirectory:NSDocumentDirectory inDomains:NSUserDomainMask] lastObject]; NSLog(@"Путь к директории Documents вашего приложения: %@", pathToDocumentsDirectory); 

Using the methods above, you get arrays containing the internals of the directory as strings: the path to the folders and files that are in this directory.

Then you use something like a loop.

 for (NSString *elementPath in directoryContents) { NSLog(@"Очередной элемент (путь к файлу или папку) лежащий в директории path: %@", elementPath); / Здесь вы можете взять этот elementPath и вывести его куда-нибудь в свой UI интерфейс. } 

I advise you to find the documentation for the class NSFileManager in Russian .

There are methods for creating files:

 Creating and Deleting Items – createDirectoryAtURL:withIntermediateDirectories:attributes:error: – createDirectoryAtPath:withIntermediateDirectories:attributes:error: – createFileAtPath:contents:attributes: – removeItemAtURL:error: – removeItemAtPath:error: – replaceItemAtURL:withItemAtURL:backupItemName:options:resultingItemURL:error: – trashItemAtURL:resultingItemURL:error: 

Methods for checking the existence of files or directories:

 Determining Access to Files – fileExistsAtPath: – fileExistsAtPath:isDirectory: – isReadableFileAtPath: – isWritableFileAtPath: – isExecutableFileAtPath: – isDeletableFileAtPath: 

And the most interesting group of methods for you to work with the contents of directories . I already mentioned two of them with examples above.

 Discovering Directory Contents – contentsOfDirectoryAtURL:includingPropertiesForKeys:options:error: – contentsOfDirectoryAtPath:error: – enumeratorAtURL:includingPropertiesForKeys:options:errorHandler: – enumeratorAtPath: – mountedVolumeURLsIncludingResourceValuesForKeys:options: – subpathsOfDirectoryAtPath:error: – subpathsAtPath: 

The NSFileManager documentation also describes another way to NSFileManager through the contents of a directory (see the description of the enumeratorAtURL method there: includingPropertiesForKeys: options: errorHandler:. Here’s an example from there that goes through the directory, through all the guts and it ignores the extras folder in it and all its contents:

 -(void)scanURLIgnoringExtras:(NSURL *)directoryToScan { // Create a local file manager instance NSFileManager *localFileManager=[[NSFileManager alloc] init]; // Enumerate the directory (specified elsewhere in your code) // Request the two properties the method uses, name and isDirectory // Ignore hidden files // The errorHandler: parameter is set to nil. Typically you'd want to present a panel NSDirectoryEnumerator *dirEnumerator = [localFileManager enumeratorAtURL:directoryToScan includingPropertiesForKeys:[NSArray arrayWithObjects:NSURLNameKey, NSURLIsDirectoryKey,nil] options:NSDirectoryEnumerationSkipsHiddenFiles errorHandler:nil]; // An array to store the all the enumerated file names in NSMutableArray *theArray=[NSMutableArray array]; // Enumerate the dirEnumerator results, each value is stored in allURLs for (NSURL *theURL in dirEnumerator) { // Retrieve the file name. From NSURLNameKey, cached during the enumeration. NSString *fileName; [theURL getResourceValue:&fileName forKey:NSURLNameKey error:NULL]; // Retrieve whether a directory. From NSURLIsDirectoryKey, also // cached during the enumeration. NSNumber *isDirectory; [theURL getResourceValue:&isDirectory forKey:NSURLIsDirectoryKey error:NULL]; // Ignore files under the _extras directory if (([fileName caseInsensitiveCompare:@"_extras"]==NSOrderedSame) && ([isDirectory boolValue]==YES)) { [dirEnumerator skipDescendants]; } else { // Add full path for non directories if ([isDirectory boolValue]==NO) [theArray addObject:theURL]; } } // Do something with the path URLs. NSLog(@"theArray - %@",theArray); } 

What I have written is more than enough. Turn on your mind and everything should work out.
