I have an iPhone app where I'd like to load a remotely served HTML form into a UIWebView and then populate that form as data becomes available from an external accessory using the "External Accessory Framework." Right now the data is entered by hand. The proposed flow is: Fetch an HTML page containing a form and put it into a UIWebVi...

I am validating an NSString to ensure that the string does not contain apostrophes. The code I'm using to do this is NSCharacterSet * invalidNumberSet = [NSCharacterSet characterSetWithCharactersInString:@"'"]; NSScanner * scanner = [NSScanner scannerWithString:string]; NSString * scannerResult; [scanner setCharactersToBeSkipped:nil]...
Would the code bellow cause my code to leak? More specifically, am I responsible for releasing the newImage or the contents of mainPageLayer (which is a CALayer object)? I get a memory warning every 4th time that method is called, but cant figure out why... I also can't figure out why mainPageLayer.contents = [newImage CGImage]; throws ...
I need a way to tell if the app being used by a user is a fresh new install (new user), or was a pre-existing user who updated. The previous app version did not track UDID's, and didn't save anything (it just ran as a simple app). Is there a way for an update to tell if the user previously installed the app? Even if that app didn't sav...
This is driving me crazy! I would really appreciate your help... My app saves a .png (referencing a photo taken within the app) to a file in the iPhone Documents directory. The app then creates and displays a UIImage from the file with no issues - but only until the app is rerun an arbitrary number of times. I think this may be related ...
In my iPhone app, I'm handed the raw source of an email, in RFC822 (or "eml") format. I'd like the HTML part of this message (if one exists). Rather than attempting to parse it out myself and converting escape chars and so on, I thought I'd check to see if anyone knows of an objective-c library to do this for me. In .NET, I've always u...

I have a view within a UIScrollView that loads an additional subview when the user presses a certain area. When this additional subview is visible, I want all touch events to be handled by this - and not by the scrollview. It seems like the first couple events are being handled by the subview, but then touchesCancelled is called and the...
I have several UIImagesView and I put them on a MutableArray. The MutableArray is retained. I add them also as a subview of a view. After adding each UIImageViews on a view I release them... for example... [myView addSubview:myImageView]; [myImageView release]; If I am not wrong, each imageView has now a retainCount of 2, because the...
