Adding a TabBarController programmatically
问题 I want to make a tab bar controller and navigation controller programmatically. My code works so far that it shows a tab bar at the bottom, but the OptionViewController doesn't say anything (no title) on the button of the second tab bar. The funny thing is, when i click the button without anything on it, the title appears (and so is his view), can someone explain to me what i am doing wrong? I tried to use the following code: - (BOOL)application:(UIApplication *)application
