I couldn't reproduce your problem (iOS 6.1 to 7.1). Although I had to make a small change in order to make it work, since it wasn't showing any text. Instead of using:
self.followEditBtn.titleLabel.text = @"Edit Profile";
you should use:
[self.followEditBtn setTitle:@"Follow" forState:UIControlStateNormal];
I'm assuming you're using a UIButtonTypeCustom type UIButton, and having a fixed frame size.
I'd like you to tell me where are you putting this code, and how is this button being initialized.
