问题
I am using MapBox example and I have imported my mbtiles file. I am getting this error:
MB Example[8517:c07] * Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '* -[NSURL initFileURLWithPath:]: nil string parameter'
I have checked my mbtile file and its loading on x-code so there no problem with it.

RMMBTilesSource is indeed using that code. You need to make sure that your OSMBright.mbtiles file is part of the project's target and being added to your bundle so that it can be pulled up as a tile source. Like any resource that you need to use in your app, it's not enough to simply be part of the Xcode project.

The reason for the crash is clear from your question itself. reason : [NSURL initFileURLWithPath:]: nil string parameter. You are initializing NSURL without passing a nil parameter. Search for initFileURLWithPath and check wether the parameter is nil or not
[NSURL initFileURLWithPath:] // Pass a valid path here

Your question cannot be answered correctly in it's current format. You need to add the code related to the issue.
The issue is you are passing a nil parameter to the initFileURLWithPath method.
Possibly the mbtiles file is missing. So it'll return nil, also issue can be in the Mapbox.
Please check that you added it to the project correctly.

Had the same error. Are you sure you copied the MapBox.bundle from the .framework into your Xcode-Project as stated here: https://www.mapbox.com/mapbox-ios-sdk/
? That fixed it for me!

I have similar problem. Don't set Custom class field in storyboard or xib...
Example:
RMMapboxSource *tileSource = [[RMMapboxSource alloc] initWithMapID:@"YOUR MAP ID"];
RMMapView *map = [[RMMapView alloc] initWithFrame:self.view.bounds andTilesource:tileSource ];
[self.view addSubview:map];
