I have a tableView:didSelectRowAtIndexPath: where I create a ViewController-Instance each time an item is selected. Sometimes it works fine for a long time, sometimes it crashes with a EXC_BAD_ACCESS very quickly. The debugger blames the line [super dealloc]; in the QuestionDetailViewController. Why? I log the QuestionDetailViewControll...
I've tried disabling it by inserting: <meta name="viewport" content="width=320" /> into my HTML string, and a dozen variations of the above in the vain hope that I just screwed up the tag syntax... but nothing seems to stop UIWebView from scrolling horizontally. And yet there are apps that manage to do this (like MobileRSS), and presu...
Hi all, Just toying with the SDK and I was wondering if possible a UITouch event can work inside a UIScrollView. I have setup a UIScrollView which handles a large UIView, inside the UIView is a UIImageView, I've managed to get the UITouch to drag the UIImageView outside of the UIScrollView but inside it's not registering the event. I ...
For example, when I call a method that returns an value, but I'm not interested in this at all, can I safely ignore that? Example, instead of: CGSize size = [str sizeWithFont:myFont minFontSize:19.0f actualFontSize:&actualFontSize forWidth:150.0f lineBreakMode:UILineBreakModeClip]; ...do this: [str sizeWithFont:myFont minFontSize:19...
Hi, im trying to write an app that will display a list off lines from a book e.g line 1, line 2 in a table view and you can then select a line to view the corrosponding text.

I've been looking at the Stanford University iphone videos on iTunes U. And saw the teacher trying to do something similar to this code but he realised and said it didn't work though I didn't get why: - (IBAction)flashPressed{ if (window.backgroundColor == [UIColor magentaColor]){ window.backgroundColor = [UIColor redColor]; }else { ...
I've got to be missing something simple, but Google is not helping. My file saves and loads fine. (I've overridden dataOfType to get some stuff in it.) Then I override fileWrapperOfType (in preparation for creating a bundle), and I get a "The document 'Untitled' could not be saved as 'test'." sheet when I try to save. Even when I empty ...
Hi, I currently have a custom UITableViewCell which contains a few labels, and an image. The "main" label is used to display people's names. Currently, I'm styling it in bold text. What I'd like to do (to gain some space and readability), is to mimic the Address Book app cell style, that is: first name in light text, and family name in ...
Hey, I have a problem with sorting NSTableColumn contents. In my NSTableView there are three columns: File, Size, Path. The contents are stored in NSMutableArray.

I'm trying to create a "project"-like document, in that it contains subdocuments in a specified directory. I'd like a brand new save of a document to set up that directory with appropriate subdirectories. I'd like a "Save As" to copy all those subdirectories and any files within them to the new location. But I'd like a "Save" to only upd...

NSMutableArray count is returning zero after adding objects to it, its been an hour of hacking away trying to figure out why, and I'm still stuck, so that brings me here.
