iOS6 Simulator MKMapKit “Couldn't find default

问题:

Running my app with the iOS6 simulator I am getting the following printed in the XCode console prior to viewDidLoad getting called:

Couldn't find default.styleproto in framework

Has anyone else encountered this, and if so have you found a reason why? My guess is that it has to do with the iOS6 Apple Maps, but who knows!

EDIT

I should add that I don't get this warning in the iOS 5.1 simulator.

回答1:

I found a way to consistently reproduce this.

First, the culprit is a set of files in the Cache folder for your simulator. Go to your Application Support folder for the iPhone Simulator:

~/Library/Application Support/iPhone Simulator/[6.0 and above]/Library

Then look inside of your Caches/GeoServices/Resources

You'll see some .styleproto files in there. These files are only created when MapKit is first used in a simulator. It may also happen on the device, but I haven't confirmed it.

If you want to test this, make sure you have the .styleproto files, then re-launch your app, and you won't see the warning again when accessing the maps.

Remove the GeoServices cache folder, quit and restart the simulator (and your app), and there is the warning!

I solved by adjusting the MKMapView in my view controller to iPhone 5 new size, now I got no warning message.

mmm...I had de same problem...I think the problem could be the 6.0 Simulator; if I set the Deployment Target to 5.1 and run the app using the 5.1 Simulator and uncheck the Autolayout check-box, I didn't have any problem, but if I use the 6.0 Simulator when I run the app, the map doesn't appear, and the message "Couldn't find default.styleproto in framework" is printed in Xcode console...

Please set your GPS settings active otherwise this error may occur again. Also,it is advisable to set the frame for the iPhone 5 .

I just turned on my wireless on device and this warning disappear and my map comes visible.

回答6:

This is old, but for anyone who comes across this thread like I did, it may also be that the option "Shows User Location" on the map view object was not checked. This was my issue and not about cache above, although I got the exact same error in console. I didn't even try the cache fix from the answer above, all I did was check that option and voila.

If your iOS simulator's GPS setting is none, you will get this waring. Just change iOS simulator's GPS setting to "Apple Stores" or other, it will gone.
