I know how to change the state of the regular button, as well as change the background color of a regular button.

I want, when the user click on it, something visually would happen to let the user know that button is selected, and wh...

But is it also necessary to do the same... when just saving data (using sqlite) from someone's cell phone, to a database that's just on their own phone? What's the worse they can do? Delete their ow...

I've enabled editing mode and moving cells around to allow users to position table view content in the order they please. I'm using Core Data as the data source, which sorts the content by the attribute "userOrder". When content is first inserted, userOrder is set to a random value. The idea is that when the user moves a cell around, the...

Any help would be appreciated: //Get the reference to our current page pageRef = CGPDFDocumentGetPage(docRef, iCurrentPage); //Start with a media crop, but see if we can shrink to smaller crop CGRect pdfRect1 = CGRectInt...
Ok, this one is really weird... I can't show code for it exactly cause it follows a pretty snake-like pattern through subclasses etc, there would be a pile of it. The important parts are that I push a view controller, which during viewWillAppear pushes another view controller onto the nav controller. My nav controller is an item in a t...
I'd like to "darken" a UIView by a certain amount. Right now, I'm doing the darkening like this: UIView *overlay = [[UIView alloc] initWithFrame:mainView.bounds]; overlay.backgroundColor = [UIColor blackColor]; overlay.alpha = 0.5f; [mainView addSubview:overlay]; Unfortunately, this also adds a semi-transparent black overlay to parts ...

The subview I'm referring to is the red area above the tabbar that also contains the "Click me" button: You can see that the cell lines kind of overlap. Here i...
I'm trying to animate an object along a path...while it's moving it should continue to "point" towards another object (or CGPoint). What should I be looking for in the framework (Cocoa-Touch) to accomplish this? Maybe something in CAShapeLayer? Though I think that's more for animating the path itself... It's not jumping out at me... ...
I'm trying to get a UISplitViewController working with an iPad app. I have the table view controller linked up under the Master pane and a plain UIView under the Detail view. I also have [window addSubview:splitView.view]; in my code. For some reason I just get a white screen even though the table view controller code is properly code...
Here is an interesting problem. On the iPhone, I have a view set up that has a toolbar on the bottom of the screen. I am currently trying to make this a universal app so that it runs on iPad as well. I would like the toolbar to be at the top of the iPad screen, so in the viewDidLoad method of the specific viewController I have the follow...

I'm using the Three20 TTMessageController in my app. I've figured out how to use it, adding on a bunch of other stuff (including TTMessageControllerDelegate methods and ABPeoplePickerNavigationControllerDelegate methods). It works great for me, after a bit of a struggle to figure it out. The trouble I'm having now is a design issue: I w...
