installed app on iphone 6 ios9 , here happened. notice black bars on top , bottom. works fine on ios8. how can fix it? i've tried building xcode 6.4 & 7. same result.

i use jena's ontclass.listdeclaredproperies() functions. every class supposed have rdfs properties (e.g. rdfs:comment), listdeclaredproperies never returns of them. how associated class , how them? update 1 i thought ontology classes have automatically declared rdfs properties. in documentation of rdfs properties written comment property "the rdfs:domain of rdfs:comment rdfs:resource". because ontology classes rdfs:resource thought should have rdfs:comment property automatically , should (together other rdfs properties) calling listdeclaredproperies function (this function returns properties of superclasses) i'm missing rdfs properties... example so when call listdeclaredproperies @ class (anyclass.listdeclaredproperies()), rdfs properties listed "normal" properties. why doesn't work? can add value of rdfs properties class or individual (e.g. label, comment etc.) explanation.
