I have created an application, but when i try to debug it, the breakpoints are created i yellow.The only difference from the above link is that, a message is shown in xcode status bar that GDB:Warning No location found for MapViewController.m 18. MapViewController is ma viewController class. I don't know what is the problem with it. The funny thing is that the application is working without any problem. But still i need to debug it. pls help
