iPhone SDK Xcode - How to get all the filenames in the documents dir

问题

I want to get all the filenames in my application's documents folder, and place them in an NSMutableArray. Nothing more, nothing less.

回答1:

There is a convenient method in NSFileManager:

NSFileManager *fileManager = [[NSFileManager alloc] init];
NSArray *files = [fileManager contentsOfDirectoryAtPath:documentsDirectory 
                                                  error:nil];
...
[fileManager release];

As of ARC you can of course drop the release statement.
