How to delete ALL FILES in a specified directory on the app?

Given a directory [[self documentsDirectory] stringByAppendingPathComponent:@"Photos/"] how do I delete ALL FILES in this folder?

(assume a correct documents directory path)

Solution 1:

NSFileManager *fm = [NSFileManager defaultManager];
NSString *directory = [[self documentsDirectory] stringByAppendingPathComponent:@"Photos/"];
NSError *error = nil;
for (NSString *file in [fm contentsOfDirectoryAtPath:directory error:&error]) {
    BOOL success = [fm removeItemAtPath:[NSString stringWithFormat:@"%@%@", directory, file] error:&error];
    if (!success || error) {
        // it failed.
    }
}

I leave it up to you to do something useful with the error if it exists.

Solution 2:

if you want to remove files and the directory itself then use it without for loop

NSFileManager *fm = [NSFileManager defaultManager];
NSString *directory = [[self documentsDirectory] stringByAppendingPathComponent:@"Photos"];
NSError *error = nil;
BOOL success = [fm removeItemAtPath:cacheImageDirectory error:&error];
if (!success || error) {
    // something went wrong
}
