First off I am very new to Objective C and iPhone programming. Now that that is out of the way. I have read through most of the Apple documentation on this and some third party manuals. I guess I just want to know if I'm going about this the correct way ... - (NSMutableArray *)makeModel { NSString *api = @"http://www.mycoolnewssit...
I'm sure there's something obvious I'm missing here, but I know that popover controls can have "titles", a header area that has a line of text above the content view (e.g. the "Tools" popover in iWork). How can I add this in my own popovers? Thanks. ...
Hi, I have a few labels on my first Ipad App. How to make them rotating? When I rotate the IPad, the Label is still the same position as before, it dowsn't rotate with. ...
For my tests, I need to create a simple app on the iPad to step 1. loads an image from the Photo library (UIImagePickerController). step 2. Then, this image is converted into texture and displayed into an OpenGL ES view. I started to define the app with the XCode Open GL ES template. Step 2 is Okay. But I have a problem launching th...
How do I add a static search bar (one that doesn't scroll with the UITableView) below the UINavigationController in the root view of a UISplitViewController. The iPad mail app has an example of one of these. Actually I would Ike to add a toolbar with a segmented control instead of a search bar, but I imagine the process is the same. ...
I want to present a modal mail dialogue like so in the iPad app: MFMailComposeViewController* picker = [[MFMailComposeViewController alloc] init]; picker.mailComposeDelegate = self; [picker setSubject:title]; [picker setMessageBody:[NSString stringWithFormat:[self emailBody], title, [link absoluteString]] isHTML:YES]; [self.vi...
I have written an iPhone and iPad universal app which runs fine in the iPad simulator on Xcode, but I would now like to test the iPhone functionality. I seem unable to run the iPhone simulator with this code as it always defaults to the iPad? Instead I tried to run on the device and as it begins to run I get the following error: dyld: ...
Hello, I have a method that needs to parse through a bunch of large PNG images pixel by pixel (the PNGs are 600x600 pixels each). It seems to work great on the Simulator, but on the device (iPad), i get an EXC_BAD_ACCESS in some internal memory copying function. It seems the size is the culprit because if I try it on smaller images, eve...
The iPad stops loading large images after about 8 or 9 images for me, since the page runs into its allocated memory limits. Since I'm showing these images one at a time, I'd like to remove the old ones from the browser cache so I don't hit the limit. Any ideas on how to do this in javascript? ...
The title probably says it all. Considering an ipad's processor is nothing compared to a macbook, I would think a Macbook should be more than capable to run the simulator. However, not knowing much about iphone/ipad development, I'd like to get some opinions on this. for e.g. how many apps are typically need to be run for ipad dev (ed...
I am trying to implement some interface changes in my app, based on the device rotation. My app is a view based app. So, its main view controller has a didload method. The app starts in portrait. Almost all changes on the device orientation triggers the shouldAutorotateToInterfaceOrientation method but this method is not called when th...

I've got an iPad app with a “drawer” table displayed in a popover. The user can tap-and-hold on an item in the drawer to drag that item out of it and into my main view. That part works fine; unfortunately, the view being dragged appears under the popover, and is too small to be visible until it's dragged out from underneath it. If I add ...
I have some code in my iPhone app like that : //fromView is a UIImageView. //self is a UIView. UIGraphicsBeginImageContext(fromView.bounds.size); [fromView.layer renderInContext:UIGraphicsGetCurrentContext()]; UIImage *dummyFromImage = UIGraphicsGetImageFromCurrentImageContext(); UIGraphicsEndImageCon...
I have an app where it seems to me that memory is not being release but I am not sure how to analyze this problem. 'Analyze' in xcode shows no problems and 'Instruments' does not show any memory leaks. As far as I have seen, it is not recommended to look at the retain counts. How can I find the problematic objects? I have added printo...
Is there a way to change the left/right margins on a table view? The cells seem too wide on iPad. ...
Hello, I want to dismiss a FormSheetPresentation modal view controller when the user taps outside the modal view...I have seen a bunch of apps doing this (ebay on ipad for example) but i cant figure out how since the underneath views are disabled from touches when modal views are displayed like this (are they presenting it as a popover ...
Hi All, I've asked this question on a couple other forums and have had zero response, so I'm hoping someone here can help point me in the right direction. I have a pretty simple one screen application for my work. It's basically just a recreation of a 1 page paper report that has a company logo, some labels, a few text boxes and a scro...
I am getting a lot of strange EXC_BAD_ACCESS crashes on the iPad that only happen on the device and not in the simulator. I am assuming that they are somehow memory related, but I am not sure. They all happen with image context related functions. One strange example is using CGImageCreateWithImageInRect. For example, if i run through a ...
I have a UIToolbar where I have dragged a UIButton. When I set the button properties to Custom, and assign an image (or background image) the graphics don't appear. However, when I give it a custom text, the text will appear. Why is it that the images don't appear? ...
