iOS error: "Setup: loading style failed: no such file or directory"

[kkaefer]

I cloned the latest version of the repository (including submodules), ran package_ios.sh without errors, and added Headers/, MapboxGL.bundle and libMapboxGL.a to the appropriate build phases.

The build compiles, but complains on startup that "loading style failed".

This issue has been discussed before for Android (#585, #719). Looking through the source, it seems that the library is looking for styles in "asset://styles/styles/". From the previous discussion, I'm not sure where asset:// is on iOS (maybe MapboxGL.bundle? I confirm MapboxGL.bundle contains the styles/ directory).

How can this be fixed?

Here is the relative path for default style.json file.

mapbox-gl-native/styles/styles/bright-v6.json

If you do not have the styles submodule, do the following in your mapbox-gl-native directory.

git submodule init
git submodule update

Yes, I have all submodules and styles/styles/* exists in the mapbox-gl-native directory. The build runs without errors and correctly recognizes styles/styles/*. (removing the directory causes a build error)

The library fails when calling useBundledStyleNamed(). A similar issue was independently reported a few hours later by another user (#856).

I also have the same problem on android.

Ok, will take a look at this. Lots of recent shuffling and using the bundled styles needs some attention, it seems.

[robipresotto]

still the same problem after set the bundledStyle to
[self.mapView useBundledStyleNamed:@"outdoors-v7"];

[incanus]

Please make sure your Git submodule are initialized @robipresotto.

[robipresotto]

I'm running: make clean > make distclean | init submodule init > init submodule sync > init submodule update and ./scripts/package_ios.sh -> after build the package I replace my current package and nothing changes (i see the styles on bundle but the system not recognise it)

This issue still exists.

It seems the commit only dealt with making sure the Git styles submodule was included. That wasn't the original issue: the styles/ directory is included, but the system crashes with loading style failed: no such file or directory.

I also ran into this issue while looking into #829. The bundled demo app gets away with copying styles/ itself directly into the main bundle directory, rather than under an intermediate MapboxGL.bundle.

Over to #1011 since this is a merged PR.

[DavidChouinard]

Thank you. I'm not sure how related this is, but I now get a SIGABRT crash. (I've isolated the issue to the useBundledStyleNamed() invocation)

[1ec5]

I filed #1014 for that crash. It isn’t related to the bundle path, although with #1011 fixed, the default style can load without running into the crash.

[DavidChouinard]

Thank you for looking into this.

(I get a black screen when not specifying a style)

[1ec5]

@DavidChouinard Even if you incorporate #1012? I’m seeing bright-v7 load by default.

Let’s continue the discussion in #1011, since this PR was for a very different issue.

[1ec5]

@DavidChouinard even with #1012, it’s going to be black unless you pass either a JSON stylesheet or a Mapbox access token. You need a token to get the default Bright style.

[DavidChouinard]

@1ec5 Sorry for the delayed response. I rebuilt the latest version and things now work as expected.

Thank you.
