Is there a way to increase the application priority for the CPU on iPhone? I notice that SpringBoard takes up too much CPU at times causing some fluctuation in performance on the device.
Hello, I'm brand new to Objective C programing for the Iphone. I was wondering if it is possible to use a tab bar, and in one of the tabs have a navigation bar so that I could drill down? I tried to look for tutorials and found this one http://www.devx.com/wireless/Article/45161/1954, I got it to work as written but I couldn't figure out to display the data I wanted. Does anyone know how? or does anyone know a tutorial for complete beginners?
Is there any property or other mechanism in iPhone OS to check during runtime whether application is running on iPad 3G or iPad Wi-Fi?
Seems like UIDevice class does not provide anything like that.
Hi
I have an existing iPhone application which starts from a UIViewController.
What I want to do is add two new table views, one which will require the navigation controller. Can anyone provide info on how to retrofit this into my app or will I need to start again from scratch using the navigation template?
Thanks

Hey!
I am planning on developing an iPhone App for a website, powered by Wordpress.
Where can/should I start codewise when developing an app for such sites? Does Wordpress have an API, should I access the (MySQL) database directly, etc?
Thank you.
The Keychain seems to be used a lot for usernames and passwords, but is it a good idea to use it for other sensitive stuff (bank details, ID numbers etc), but with no password? What kind of encryption does the keychain use? The scenario I'm concerned about is a thief acquiring an iPhone (which is screen-locked) and being able to access the file system to get this info.
Also, would using the Keychain involve export restrictions due to the use of encryption?
I was wondering how I would go about creating a view that persists through all the over views and controllers in the application. Similarly to how Soundcloud does it with their music player in their iPhone app (See pic). No matter where you go in the application the music player view stays at the top below the toolbar.

I'm trying to restore iPhone OS 3.1.3 to a 3GS that has been upgraded to iOS 4. iTunes refuses to complete the install. What needs to be done? I am currently using the GM XCode. Should I be using the latest public stable version instead?
Update:
XCode reports that "The baseband cannot be rolled back".
Hello.
I'm very new on iPhone development. I'm trying to draw a cross over the image obtained from camera.
I'm using a custom ViewController that inherits from UIImagePickerController.
When I star the application, I see the cross, but a few seconds after the cross disappears.
Should I use cameraOverlayView?
Thank you

Thanks in advance!
Hi
Anybody know how to programmatically generate MP3 files with bookmarks that can be used in iTunes / iPod / iPhone / iPod touch? Specifically text bookmarks (bookmarks with titles) that the listener can skip to a specific point in time in the audio file. Also how to add the text transcription of the podcast's content.
Even better if you have an example Cocoa code or library to write the MP3 file.
Thanks.

Hello guys!
I want to use the FileMerge utility on my mac, but it isn't installed. I searched in the google and there is written that it will be installed with the developer tools. So the big question is where can I find the developer tools, because I downloaded the iPhone SDK 3.2 beta 5, and installed it, but I can't found the download location of developer tools. Maybe can you help me?
In the Linked in iphone application I noticed that they have a tableview, see the following picture with what appears to have a triangle indicator pointing upwards.
Notice how the tableview cell has a little triangle pointing upwards and is part of a tableview cell.
The triangle is the ---^--- part of the image.
I'm wondering. How do you make a UITableView with this triangle indicator, and what is this effect called?
Thanks
I have a uiwebview embedded within an iPhone app of mine. I want to be able to have certain links within that webview open into the full mobile safari app (i.e. not my embedded version of it). Is there a simple way to structure some of my hrefs to force this, instead of every link opening within my embedded webview?
Thanks.
