Hello, Many of my clients use Macs and I'm getting weekly emails about bugs in my web-app software that are Mac only issues. I have a limited budget so I'm hesitating going out any buying a $1,200 Mac for testing. Would an iPad work? Or would that not be the same kind of browser rendering as a Mac Book? thanks! ...
I am have an app I am writing that will need to download alot of images, possibly 10,000. Right now I can get to about 3000 before I run out of memory and the app crashes, just depends on the image files sizes. I am downloading them on a background thread and showing the progress to the user. I wrote a helper class thatI am accessing ...
I have to download a ton of images and I am doing it on a background thread, problem is all of the downloaded data is not released until I go back to the main thread which is fine a for couple hundred images but when I get into thousands the app runs out of memory and crashes.

I'm wondering if it's possible to lock the aspect ratio using a meta tag, or by any means at all? I'm making a web app where the target platform is the iPad, but it only really makes sense if it is always in landscape orientation, and i was hoping to ensure it was always presented that way regardless of the device orientation. ...
I have a little experience with iPhone development but am new to iPad. I realize that apps are sandboxed and cannot access each other's data, but is there any way that the iPad app can access information about the eBooks on the iPad--for instance, the titles and authors of these books? ...
I have an iPad application with screen flows which don't map neatly to the navigation controller model, but still have the concept of "Back". I'd like to manage my own toolbar and have a "Back" button where I decide where it goes. Is there a way to make a toolbar button have the look of a back button as in UINavigationBarItem? Thanks ...
I have 2 UITableViewControllers, both are using same data source but for some reason one of them has weird header gap on the top. I don't understand why. When I'm changing style to UITableViewStylePlain the positioning is fine but I need grouped style here. Any thoughts? ...

What are the consequences of overriding internal UIViewController methods? [UIViewController viewDidMoveToWindow:shouldAppearOrDisappear:] is giving me some problems. It resizes my frame to values I do not desire sometimes. I do not even know where it picks off the new frame's values (it is close to the size of the superview to where I ...
I've been trying to work a UIActionSheet into my App. The idea is, if you exited the app in a certain state, it would popup on launch and ask you if you'd like to continue or reset. Here's the code: NSUserDefaults *prefs = [NSUserDefaults standardUserDefaults]; continueYesNo = [prefs boolForKey:@"keyContinueMeeting"]; if (continueYes...
I'm looking at ways to manage a large set of images within Mobile Safari for iPad. In this case I have a web app that will move the images using webkit CSS3 animations (supposedly taking advantage of hardware to do so). I've noticed that if I have more than 10 large images (200-300K each) I hit large performance issues. Animations are j...
Hi there, I would like to write an iOS application that uses the native support to viewing multiple file types (e.g. HTML, PDF, Pages, Word) in a high level control such as UIWebView or Quicklook. Nothing too hard here. However I would then like to support selection of text, adding custom Context Menus to a selection and, at a minimum,...
Hello, I've recently been trying to incorporate an intensive sound management class, where sound playback precision is a must. What I'm looking for is the option to load a sound, set the playback starting position (or playhead), play for a certain time, pause the sound, set the 'playhead' position to a new interval and resume playback a...
Hello all, So I am presenting a full screen modal view when the user selects an item from a popover containing a table. The problem is when the modal view is displayed and the iPad is rotated, the status bar spins, but the view stays in whatever orientation it was in before. It looks very strange. Because I am presenting it from a pop...
Hi, I am creating one app in which I need to view pdf, word, and excel files. Can I view these files without using web view? Can anyone provide me with sample code for doing the same. Thanks alisha ...
Hello all, So I have a popover being presented from a barbutton. However I am having some rotation issues when a modal view is being displayed over it. The view inside the popover is not rotating properly. I have all of the delegates set to yes, so it should automatically handle this. This is only happening when that modal view is b...
I am working on a Google Maps-like scrolling/panning system. The system is supposed to be a lot simpler than the "original" (no zooming) and as such is built in a quite straight forward fashion: There is a containing div representing the viewport with overflow set to hidden and a fixed size This div contains another div that's being pa...
Hi I have a iPad app with the following code tied to a button's (bMyDocuments) TouchDown event handler: UIPopoverController uipoc = new UIPopoverController(new Pop2()); uipoc.PopoverContentSize = new SizeF(200f, 300f); uipoc.PresentFromRect (bMyDocuments.Frame, v, UIPopoverArrowDirection.Up, true); Pop2 is a blank UIViewController wi...

What I'm looking for in the framework: Allows me to focus on the application logic I don't have to code "low-level" network programming (I've done it too many times that I dont wanna do it again =p) Should be actively maintained (po...
