Hello everybody, I'm making my first steps in iPhone developing and I'm facing a problem at present. When I set an outlet to an arbitrary control, for example to a label or a button, and switch to the according view with my TabBarController, the application crashes. Within the ViewController.h file I declared in the @interface section and and used the @synthesize statement in the .m file. When I do the same procedure with a button and set an action instead of an outlet, the view is loaded fine but the app crashes when I press the button. To be sure that I'm able to set an outlet correctly, I quickly created an app with a simple label which gets its text changed at startup - everything is working. Is there anything special about setting outlets while using a TabBarController? Thanks in advance.
