Lets say you want to remove(delete) all the files of a particular extension say PNG from the Documents folder of the app. We can use the following code snippet. NSString *fileExt = @"png"; // get the file manager NSFileManager *fmanager = [NSFileManager defaultManager]; NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES); // get the doc directory NSString *documentsDirectory = [paths objectAtIndex:0]; // get contents NSArray *contents = [fmanager contentsOfDirectoryAtPath:documentsDirectory error:NULL]; // enum NSEnumerator *e = [contents objectEnumerator]; NSString *fname; // loop while ((fname = [e nextObject])) { // compare if ([[fname pathExtension] isEqualToString:fileExt]) { // remove it [...]
