Question

I can’t work out why it keeps failing. It returns NO. I have searched this all afternoon, but nothing explains why or how to fix. Calling [[NSFileManager defaultManager] isWritableFileAtPath:] returns NO, which leads me to believe that the existing plist file can not be overwritten, but I can’t work out how to change this.

Answer 1

You can write ONLY files in Documents directory. But your plist file is not there

NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
    NSString *documentsDirectory = [paths objectAtIndex:0];
