Hey. I have a reload-button in my UINavigationController that is supposed to send a reload-selector to the current loaded view, or the view on top, I don't know what to call it :p I have no idea where to start, so if someone could give me a pointer (no, not that kind :p), that would be great :) Thanks! ...
Is there a way to load a portrait only view controller in portrait orientation even though the parent view controller (and phone) is in landscape orientation? This particular UIViewController only fits in Portrait mode (it's a color picker), so the code in shouldAutorotateToInterfaceOrientation: returns YES only for portrait orientatio...

How is this done? is it 2 types of apps joined? Im thinking keeping all the xib files for the menus etc. but I am not sure how to connec...
Hi, I'd like to handle touches (horizontal slide in particular) in a UIViewController subclass I did, but the problem is the controller's view contains a UIScrollView which covers the whole screen, so "touchesBegan:" and "touchesEnded:" events are never called in my controller. The scrollview only scrolls vertically. What would be the ...
I am working on my first simple tabview controller app. The first tab is a setup tab, and I just had a tester provide an unexpected use case. In order to address this use case, I need to execute when the user is leaving the view and before I load the next one. Running code in the next view is too late. What method is called from the c...
Alright, so here's the problem I'm having (it's a weird one.) I added a new UIViewController for the app I'm building. The first view controller works perfectly, orients correctly, etc. The second one orients horribly. This is how it looks if you start in landscape and then change orientation to portrait: And then, if you start in p...
Hello, I currently have an app that has a UIScrollView with paging as the primary ViewController. However, currently, I am trying to animate to a new ViewController, but whenever I use presentModalViewController or an animation using UIView, I am still able to scroll, left and right on the original view. I was successfully able to ke...
Hey guys! I am learning tons on this thing. Reading also, but this is awesome! Ok.. so long story sort I hope.

I was helped here a while ago about loading images from an array, but would like to know the exact details please. Where does the code go if my app will be as simple as images that load from an array depending on whether the user chose the next or previous button? Does it go in the View Controller class? What do I need if I literally j...

I have a model class and two View Controllers. @interface Disc : NSObject { NSString *discType; NSNumber *capacity; } @property (nonatomic,retain) NSString *discType; @property (nonatomic,retain) NSNumber*capacity; @implementation Dis...

UIView's that don't handle their events pass them up the chain. By default, this passes them to their parent View, and if not handled (ultimately) to their parent UIViewController. UIScrollView breaks this (there's lots of questions on SO, variations on the theme of "why does my app stop working once I add a UIScrollView?) UISV decides...
