iOS7 Xcode 5升级使Longpress崩溃应用

Question

I have an app that I've been working on, which worked perfectly a few hours ago. I downloaded DP5 of Xcode-5, upgraded my storyboards using the built in upgrade storyboard features.

When I launch the app it works. It's a basic map app. I have an action for to register a longpress, and then drop a pin annotation on the map and now the app crashes without any error, except showing the line in the compiler code where it fails: 0x102d49c: calll 0x102d4a1 ; -[NSPathStore2 isEqualToString:] + 17 0x102d49c: calll 0x102d4a1 ; -[NSPathStore2 isEqualToString:] + 17 and a cryptic message of EXC_BAD_ACCESS .

I don't even know where to begin troubleshooting. I'm downloading the release build of Xcode 5 right now to see if that fixes it.

--Update--

I've also tried a clean build, restarting the simulator and Xcode.

I used breakpoints and it seems that the app is having trouble specifically with adding the annotation to the map [self.mapView addAnnotation:annot];

Woot! Solved the issue. Hope this helps someone.

I was using Apple's stock code for annotating maps .

When I built the app for iOS6, by default, adding a pin annotation did NOT show the disclosure right away.

So I added this line of code to select the annotation and display my annotation by default. Removing this line fixed it, and in iOS7, the disclosure shows by default anyway! [mapView selectAnnotation:pinView.annotation animated:YES];
