iOS7 - View under status bar - edgesForExtendedLayout not working

Question

I have a project that was built last year, and it uses XIBs, no storyboards. The XIBs do not use Auto Layout, but they do use some Autosizing. I have an issue when running

Answer 1

Apple are pushing you to use autolayout to accomplish this. You need to set a constraint to the "Top Layout Guide" from the top subview in your view.

See this document for examples:

https://developer.apple.com/library/ios/qa/qa1797/_index.html

To do this without XIBs, you'll need to add the constraint programatically. Apple's docs give a good example of this, which I've summarised below.

Giving that the topLayoutGuide is a property on a view controller, you just use it in your dictionary of variable bindings. Then you set up your constraint like normal:

id topGuide = [myViewController topLayoutGuide];
NSDictionary *viewsDictionary = NSDictionaryOfVariableBindings(button, topGuide);
NSArray *constraints = [NSLayoutConstraint constraintsWithVisualFormat:@"V:[topGuide]-20-[button]" options:0 metrics:nil views:viewsDictionary]; 

The documentation for this can be found in the UIViewController class reference.
