how to set iOS 6/7 Deltas programmatically

Question

I was developing a UISplitView app by using Xcode 4.6 when I left iOS6 I had design:

Now I migrate to new Xcode5 and now I have this design:

UINavigationBar overlaps completelly my UISearchBar...

Leo Natan told me about using a iOS 6/7 Deltas but since I'm creating and adding my UISplitViewControllers programmatically,

this may doesn't work I need to set the iOS 6/7 programmatically but I don't know how, any help I'll appreciate

If you want to do this in code, you have to work with frames. if (iOS7) {view.frame = ...} else {view.frame = ...} – Tyrannicide

@PetroKorienev Or just change constraint constants? It's easier than to update frames. – Pupil

The OP doesn't use auto-layout, and initialized his controllers in code. Adding constraints in code isn't way easier than updating frames.. – Tyrannicide

Answer 1

In iOS 7 there are now extended edges, and that's why navigation bar overlaping the searchbar. You can set self.edgesForExtendedLayout = UIRectEdgeNone; this is UIVewControlelr property. You can also make checks depending on version of iOS and You can do things depending on current version of iOS in device.

NSString *version = [[UIDevice currentDevice] systemVersion];
int ver = [version intValue];
if (ver < 7){
//iOS 6 work
}
else{
//iOS 7 related work
}

Also, you can use NSFoundationVersionNumber

if (floor(NSFoundationVersionNumber) > NSFoundationVersionNumber_iOS_6_1) {
  // > iOS7
} else {
  // <= iOS6
}

This way is suggested by Apple in iOS 7 transition guide. – Imperfection

Answer 3

You can create a makro for solve this problem. it is useful for me.

#define iOS7Delta (([[[UIDevice currentDevice] systemVersion] floatValue] >= 7.0 ) ? 20 : 0 )

If the view's embedded in a UINavigationController - simply untick "Translucent" for your root navigation bar.

In storyboard, select Navigation Controller Scene, next select Navigation Bar and in Attributes Inspector (Utilities - 4 tab) untick "Translucent"
