Hello, I’m trying to set up an iPad test application, window-based, where I have a single view controller and a single view. When I rotate the iPad, I want the orientation of the toolbar to change, but not that of the view itself. For example, a sort of background view that you work in is fixed to the device, but the status bar and tool...

I am just trying to make a timer. I would like to use UIDatePickerModeCountDownTimer mode of the UIDatePicker, so that when the user simply selects say 15 mins in the picker, they are passed back to a screen that shows the value of 15 mins in a label that they can then count down from. As I have tried to get the value from the DatePicke...
I found an example of a paging UIScrollView in Apple's developer docs and it's just what I want for my application. I have a main view with a "Help" button that I want to present a view that users can page through to see all the help topics. The sample is at: https://developer.apple.com/library/ios/#documentation/WindowsViews/Conceptu...
In my iPhone app, I display a list of names. I want the name to be formatted either as ("First Name" "Last Name") or as ("Last Name, "First Name") Is it possible to know the users' contact app preference using a API? ...

Hello everyone, I can't add .a files (static libraries) into my repository. Why ? Is there any way to "force" SVN to accept them (at least as static files...) ? Thank you ...
I would find useful, in some cases, and under the user's permission, to block the device so only the running application can be accessed unless the usrer's password (pattern or whatever is used to unlock the session) is introduced. I guess the mecanism should be something like: The application asks the os to do this, the OS asks the use...
In Mac OS X, there is AppKit addition which supports reading and writing of NSAttributedString as RTF format. Equivalent in iOS? Should I make my own? ...
I'm working on an existing, large-ish codebase, and after upgrading the iOS SDK to 4.1 I am now seeing very strange behaviour. The crux of the matter appears to be a particular class that will no longer alloc - it is throwing a bad access in obj_msgSend, and seems to be the Class object on the stack that objc_msgSend doesn't like - altho...
This is weird. My application schedules local notifications whenever it is sent into the background, and while the first notification is being displayed correctly, as soon as the one after that should be fired, the whole application crashes. Yes, in the background. While no code is being executed. No console output is given, I just get ...
Hello! There’s a feature I’d like to use on iOS. It has already been requested on Radar and people from Apple say that they will probably implement it. Is there a way to get to the particular bug report in Radar so that I can watch the progress? I know I can’t see other people’s bug reports on Radar. What if I file a duplicate bug report...
I just figured out that - instead of using a UIImageView to show an image - I use an UIWebView, it uses much less memory. Does that make sense for anyone? What I did was to get an ordinary .jpg file with about 280kb in size and show it on a simple app with just an UIImageView. Looking at Instrument's Object Allocations tool, the applic...
Hello! I’d like to take some video frames and encode them into a video. It looks like that’s exactly what AVAssetWriter was meant for, but no matter how I eyeball the docs and Google I can’t find any way to actually use it. From the docs it looks like I need an input (AVAssetWriterInput) to feed the writer from. Fine. But the AVAssetWrit...
I've been working on an iPad application that has about 15 view controllers. Some of the view controllers are full screen, others are embedded inside the other view controllers (think split view controller). On the iPhone navigation is very straight forward. Even if you have a ton of view controllers, you are using one of Apple's root v...
I need to change my audio depending on whether or not headphones are plugged in. I'm aware of kAudioSessionProperty_AudioInputAvailable, which will tell me if there's a microphone, but I'd like to test for any headphones, not just headphones with a built-in microphone. Is this possible? ...
Is there a way to call code when a modal view is finished dismissing? EDIT: I'm sorry, I didn't clarify earlier. I'm trying to dismiss a UIImagePickerController and then show a MFMailComposeViewController and attach the image data to the email. When I try to call [self presentModalViewController: mailController] right after [self d...
HI all, In xcode I am trying to load different nib file in case I am using iphone/ipod or ipad.

Hey all, I've been using Core Plot to draw some charts for an iOS app I've been developing. While core plot is excellent as a charting application, it's a performance hog when it comes to any kind of user interaction. To get around this, I started doing a lot of the following: UIGraphicsBeginImageContext(view.bounds.size); [vie...
I am developing an iPhone application. I am unfamiliar with Xcode, so please bear with me. I have the iOS 4.1 Device SDK. When I select "Simulator" in the "Active ..." drop-down box, my application compiles without errors and runs in the iPhone simulator. When I select "Device" in the drop-down box, however, I get the following linker e...
