ios - Issues when testing on iPhone 5 on 4inch retina display simulator -

-

so released app , seemed fine. of sudden got reviews in , emails app did not function , doing weird things. turns out users using iphone 4s , 5. have iphone 4 running 6.1.3 , worked great. did testing in xcode found using iphone sim 3.5 inch screen worked perfect. if switched 4 inch retina display went crazy... button functions other screens mixed in current view. long story short... went in , fixed , ran tests using simulator. tools updated , looks good. released update itunes had issues use app.

but... couple people have been speaking issues still there. not understand how since test in simulator. know how test app on version ios , if works on sim work on actual device. baffled issue.

i using xcode 4.6.2 ios sdk 6.1 , app deployment target 4.3
