Add lightmap at runtime has problem on iOS

I saved all my scene objects to prefabs(to use them in multiply scenes) and saved their lightmap information(lightmapIndex and lightmapScaleOffset, i get them from renderer of the objects, also their transform information). So when building a new scene, i create the object from prefab and set all these value to them. Also i add the lightmap texture to the lightmap array. In editor mode it works fine, but on iOS there are black lines on the objects, which indicate that the lightmaps don't match perfectly. Is there anyone who has encountered this problem as well?Hoping for ur help!
