How Can I solve this error code in Xcode5.0.2? Thread 1 signal:SIGABRT error

Question

I recently upgraded an app I created iOS 7. I then tried to run the app, and the build said it succeeded, however the app crashed and directed me to this code and the error message:

2014-03-03 14:40:24.686 BluetusRece[2112:a0b]

This looks like a dead outlet connection to a Label named `label_1`. See line one. — dibi, Mar 03 '14 at 07:38
may be this is an issue with your xib. may be you forget to set reference or something else. — Nirav Jain, Mar 03 '14 at 07:38

It looks like your startup view controller does not have an IBOutlet property named label_1 that some UILabel is trying to connect to from your NIB or Storyboard file.

Please open your NIB or Storyboard and look for UILabel connected to label_1 IBOutlet property in your startup view controller and then either delete the connection or add a property as below to your initial view controller's header file:

@property (nonatomic, weak) IBOutlet UILabel *label_1;

This line is going to add missing IBOutlet and let you get past this crash.
