I have a UITabViewController application with 4 tabs and each tab with a UINavigationController, each with a UItableView. When a row is clicked it navigates to another view.

The determination of a position takes some time. When and where should the location manager be started? Now I'm starting the location update one view before the result view (which needs the location) is loaded. If the user taps to fast I get 0.0 coordinates. To get the right timing the startUpdatingLocation should be called three views...
Hi everybody I'm programming an iPhone application. This application contains a home page, which I would like to be almost the same as the one in facebook for iPhone : rows of icons, each icon corresponding to a category of my application.

As a proof of concept, I want to create an application that retrieve the current coordinates, calculate the direction towards an another point and, using compass, rotate an arrow image to direct to that point in space. I know how to retrieve current coordinate and to rotate the image through CGAffineTransformMakeRotation, but I haven't ...
I have UITable which contains some UIButtons. I would like a way to use the label. The problem I have is that I need two tag labels, one for retrieving the cell in tableviewCellWithReuseIdentifier and configureCell. Until recently I have been using the UIButton.title to determine which row in the table I selected. The (invisible) text...
I seem to be encountering a very odd problem which only occurs when trying to insert a new NSManagedObject into a new section. Basically my sections are days and individual cells are associated with times. When I MOVE an object to a day which doesn't currently have another object (table row) associated with the day, the table needs to cr...

But, I want a large calendar view also respond to such gestures as pinch-to-zoom and swipe, even if a finger crosses somehow child views. By now, there is an overlaying tr...
Hi all, I want to write a simple media player which displays lyrics that are retrieved from the web. I know once LyricWiki was such a source, but now no longer exists. Does a new API or source for lyrics exist that I can use ? When I do get the lyrics, how do I sync them with song ? I know the MPMediaItem class has the MPMediaItemProp...
Hi, I'm seeing these all over the place but I'm wondering what controls are used here? What is the thing with the arrow pointing right? Is it a UIRoundRectButton with a ">" (greater than) character? What is the box with the rounded corners below which allows separaring content using a horzontal line? Also looks like a button... Th...

I've read several topics to moving a UIButton and can touch the button when its moving. Now i'm using a UIView beginAnimation, but the button can't be touched when its moving.
