NSHomeDirectory Remove All Files

Question

How can I remove all of the photos that I've saved in NSHomeDirectory ? They are photos, saved in a path formatted as follows" /var/mobile/Applications/3EEDBD68-5496-458D-9EF0-062746847C83/Photos/1234.png .

And what do I call if I only want to remove a certain photo (ie that 1234.png listed above)?

To remove one item, you could call:

NSString *filePath = @"/var/mobile/Applications/3EEDBD68-5496-458D-9EF0-062746847C83/Photos/1234.png";
[[NSFileManager defaultManager] removeItemAtPath:filePath error:&error];

To remove all of them:

NSString *directoryPath = @"/var/mobile/Applications/3EEDBD68-5496-458D-9EF0-062746847C83/Photos/";
[[NSFileManager defaultManager] removeItemAtPath:directoryPath error:&error];
// Re-create the directory
[[NSFileManager defaultManager] createDirectoryAtPath:directoryPath withIntermediateDirectories:YES attributes:nil error:&error];
