I checked your code. It’s working for me. Check any error you are getting using the modified code below – (void)removeImage:(NSString *)filename { NSFileManager *fileManager = [NSFileManager defaultManager]; NSString *documentsPath = [NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES) objectAtIndex:0]; NSString *filePath = [documentsPath stringByAppendingPathComponent:filename]; NSError *error; BOOL success = [fileManager removeItemAtPath:filePath error:&error]; if (success) { UIAlertView *removedSuccessFullyAlert = [[UIAlertView … Read more
