Hi, I googled for the memory issue associated with UIImage and came across many threads talking about the problem but no real help or solution. I know when we use -imageNamed: the object is being cached so it's better to use initWithData:. When we use drawRect: and UIGraphicsGetImageFromCurrentImageContext(), does the image goes to cac...

Now I want to crop or draw a smaller image of the existing image in database which I am getting from the querry.

I am using ad hoc distribution to run a beta test program and have run into a couple issues with distributing app updates. The only way I have been able to get an app update on a device through ad hoc distribution is to delete the app from the device first and then install the update. This adds extra steps for beta testers and erases t...
I have a UITableView with one section. The last row it to add new objects, and it reads "Add Object". How can I make this cell stay in editing mode so that it will always show the plus icon?

I have a simple app which has a bunch of icons which should be dragged into a circle. Both the icons and circle will be PNGs with alpha channels. Could someone please help me with basic code to set the bounds of these objects to the non-alpha channel data? ...
Almost all of the time, if there's a bug, it's Your Fault™. But sometimes, it really is a bug in the API/OS. As iPhone OS is relatively new (especially 3.x) there are always a few bugs to look out for. I think it would be a good idea to compile them in a list. If you know of any, please list them, along with which versions are affected,...
I was trying to follow the Table View Programming Guide for iPhone OS but was having trouble creating a new Table View Controller that loads its data from a nib file. Specifically, I was trying to follow the steps in this part: If you prefer to load the table view managed by a custom table-view controller from a nib file, you mu...
I am having a problem that may be simple to fix, but not simple for me to debug. I simple have a button inside a view in IB; the file's owner is set to the view controller class I am using and when making the connections, everything seems fine, ie. the connector is finding the method I am trying to call etc. however, I am receiving this...
Hi, I am trying to pick a video from the photo library. In principle I know how to do it you set the mediaType of the image picker to an NSArray with kUTTypeMovie as its only object. But this doesn't seem to work on an iPhone 3G. Since OS 3.1 you can store videos you've received in your photo library. When you start the build in 'Photos...

I upgraded to Xcode 3.2 and now can't seem to add a number of frameworks, specifically the media player. A number of frameworks do not show up on the "Add Existing Frameworks Sheet". Per another question I tried setting the "Framework Search Path" to $(SDKROOT)/Library/System/Frameworks but that didn't seem to make any difference. ...
There are plenty of objects in each iPhone app witch will live forever till app dies. They are: application delegate, window, main view controller, may be navigation or tab controller, all the objects within them. Why on Earth should I release them just before quit spending precious CPU cycles? As far as I understand, apps process will b...

There are certain portions of my app that would be better to highlight to the user if they're on the phone. Is there a call to check to see if we're on the phone? Unfortunately, "call" is a horrible word to check for in API documents for obvious reasons. ...
Getting a "Pattern colors are not supported by the iPhone SDK for iPhone OS versions prior to 3.0." error from Xcode when compiling an application for iPhone OS 2.2.1. I'm using Xcode 3.2 on Snow Leopard. The interesting thing is that others (I don't know host OS or Xcode version) are compiling this code fine. ...
