This question is almost embarrassing to ask, but I can't find the answer in any documentation. I have a UIButton in a view. In IB, I set the button's background to a colour. The original rectangle in the Identity Inspector shows a half-black, half-white rectangle for the button's background. I can't find anyway to set the background ...

I have everything working data-wise but the problem i'm running into now is formatting on my labels. The picker is presented with it's own toolbar in an actionsheet with a button on the right side of the toolbar. It's initial state is ...

I now want to toggle one of the UIButtonItems each time it is tapped (just like the shuffle button in iPod, white blue white blue.

The Issue My PSWSnapshotView's end up exactly snapshotIndex too far to the right inside the _scrollView (40px offset). Yet, they are set with their frame to have the first one at (0, 0), though that first one shows up at (snapshotInset, 0) instead :/. The Code - (void)layoutViews { CGRect frame = self.frame; CGFloat pageWidth ...
I want to create a subclass of UINavigationController which always starts with the same root controller. Nothing special, so (to me) it makes perfect sense to override the init method like this: - (id) init { rootController = [[MyController alloc] init]; if (self = [super initWithRootViewController:rootController]) { // do...
For some reason, I'm having trouble with making a textfield the first responder. I have a UITableView with two rows. Each row has a label and a UITextField. The textfields are tagged kLoginRowIndex = 0 and kPasswordRowIndex = 1. As you might have guessed, I use this for setting login and password. If the user taps on the return button ...
Hello guys, I'm trying to create this sort of "pop up action sheet" view similar to the in-call view in iPhone's phone app. I believe this is a custom view, since I can't seem to find this in any apple references. But somehow the Google app and Discover app both have this view and look awfully similar (I've attached the images below). ...
Hi, I have a UIView inside my xib in IB and inside that is a UIScrollview that is a small 80x80 square and dynamically loaded with 8 or so 80 x 80 thumbnail images. The UIScrollview is not clipping the images so that they extend out either side so you can swipe left and right to scroll a chosen image into the the centre, paging is on s...
Can anyone explain why it's not possible to create your own view controller hierarchies using UIKit on the iPhone? Let me explain: when creating applications using a complex view hierarchy and navigation logic, it's a good idea to have certain views controlled by a dedicated view controller. These controllers can have their own subcontr...

Hi, if I change the frame of a UIWebView (scalesPageToFit property is YES), what do I have to do that the zooming level of a currently displayed webpage persists? Let's say I have a UIWebView frame with a width of 200 pixels, and has zoomed into a website so that only one column is visible. After changing the width to 300, I still see ...
I'm working on a few basic apps/utilities/games with the iPhone to get a better grip on it. I currently have a setup where a CGRect moves wherever the finger moves, however I don't want the CGRect to go outside the bounds of the view. Original Method - (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event { UITouch *touc...
Hello there, I'm trying to add a UILabel to an MKAnnotationView as a leftCalloutAccessoryView right after a pin got selected for the first time in the MKMapView. Adding the label is not a problem: The callout gets selected and opens, and this is when I add the label to the callout view. The callout gets automatically expanded to the lef...
I'm trying to debug some touchesBegan/Moved/Ended related slowdown in my game; I think that some of my touch responders are not unloading properly, and so as the game runs on more and more of them stack up and the touches get less responsive because they have to pass through a larger and larger responder chain. Is there some way to vi...
I'm gussying up a Cocoa-Touch UI composed of basically two view hierarchies. Users need to drag objects from one (hierarchyA) INTO the other (hierarchyB). The problem I'm having is with the layering of these views, especially as they're being dragged. I don't know of a way to allow parts of hierarchyB be layered below a UIView from hiera...
I'm experiencing a bad looking graphical glitch with UIDatePicker, and I'm wondering if anyone else has seen and/or resolved it.

I have tried removing all other graphical elements. I...
