Is this normal? Is this a bug or I am doing something wrong? newDocPopoverController = [[UIPopoverContro...

As far as I can tell, technically MKPolyline and MKPolygon should not be functional/available when running on an iPad or any other device prior to iOS4. Nevertheless, when I installed 3.2.2, on the device, and updated my build tools with the latest (non-beta) iOS 4.2 SDK, they both work just fine, along with their associated views. Wha...
In my iPhone app, I have a UIViewController with two subviews: a main UIView (let's call it mainView), and a secondary UIView (let's call it secondView), which is usually hidden but is sometimes shown (e.g. user settings). In my UIViewController, self.view is set to mainView. When the user switches to the subview, I call [self.view addSu...
I came across a very subtle issue. Usually things are okay, but occasionally the current UIviewController has no title. When I call another viewcontroller called via [[fruitDB navigationController] pushViewController:fruitc animated:YES]; there is no "back" button. The area on the top left of the navigation bar is still active thoug...

Hey all, I am at a loss. I have an NSDate that gets passed to a UIDatePicker. When I am set to the Eastern time zone, all is fine.

How can the ability to select cells in a Cocoa Touch TableView be completely disabled? I have managed to get my code to a state where selection seems not possible, but if you hold your finger on a cell for a moment or two it will turn blue (selected) until you move off it. How can it be completely disabled? ...

I am attempting to place scroll view within a UIView that is smaller than the entire iPad screen. I simply add the scroll view as a subview of the UIView and it appears just fine, however when I scroll it, it moves outside of the bounds of that UIView effectively covering up any UI elements that are placed above it. Is there some way to...
You can scroll an UIPickerView both by swiping and by tapping items under or above the selection belt. You can populate an UIPickerView by either specifying NSString as titles or reusable UIViews for each row. What I've noticed is that when I switched from providing strings to providing view, tap to scroll no longer worked. Is this exp...
I've got a UITextView that is not editable by default so that data detectors show addresses and phone numbers. I'd like to be able to let the user single tap anywhere in the text view to set it editable and put the insertion point there. Unfortunately, I can't get the insertion point and a single tap just enables editing of the text vi...
