White screen on build

[gijs]

Hi,

I'm using the dynamic framework (build target ios8) but I'm getting a white screen on Build & Run:

I've followed these instructions and I'm running XCode 6.0.1 on Mavericks.

Did I miss something? I'm new to iOS development so it's probably something obvious.

Thx!

Without having set autolayout constraints on your map view, I'm guessing that because of iOS 8+ behavior, your view isn't resizing properly at viewWillAppear: and later. You can confirm this by setting up that method and setting a breakpoint, then p mapView.frame, which will likely be CGRectZero. Or you can set a different color for self.view.backgroundColor and see if the all-white changes to it instead, meaning your map view isn't visible.

To fix, try something like this in your viewDidLoad:

mapView.autoresizingMask = UIViewAutoresizingFlexibleWidth | UIViewAutoresizingFlexibleHeight;

This old-style way of setting masks should get auto-converted to constraints and keep your map view the same size as the root view.

Thx!

Setting self.view.backgroundColor = [UIColor greenColor]; indeed turns the screen to green, but the autoresizingMask doesn't fix the sizing of the map. I'll try some more tomorrow...

Hmm, can't figure it out... If anyone has hints that would be great. (I'm going to read some iOS8 tutorials in the meantime :))

Going to close for now since this isn't specific to Mapbox GL, but feel free to post back @gijs with anything you find for completeness here.

Will do. Thx for now!
