I have a custom UIView that is composed entirely of CALayers. In the awakeFromNib method it creates and sets all the CALayers into their appropriate positions (CAGradientLayer, several CATextLayers, and a few custom CALayer subclasses). The custom UIView does not override the drawRect: method because there's no drawing done directly int...
I need to extract the contents of the title tag from an HTML page displayed in a UIWebView. What is the most robust means of doing so? I know I can do: - (void)webViewDidFinishLoad:(UIWebView *)webView{ NSString *theTitle=[webView stringByEvaluatingJavaScriptFromString:@"document.title"]; } However, that only works if javascript ...
Is there a way to make it so when a site is viewed with a phone or other small mobile device the site automatically recognizes that it is being viewed as such and either re-directs to a phone friendly subdomain mirror or automatically calls a script that makes it phone friendly? Any articles or advice would be greatly appreciated! ...

Hi, I'm dragging things around in the Interface Builder... I'd like to specify whether an image is in front (like an indicator) or behind of a button (like a background). I don't see any z-index property as I'm used to seeing on other environments. If there isn't a z-index property what is the best way to go about what I'm trying to a...

I have an iPhone application I am about to modify for the iPad. My problem is: the application is designed to work for iPhone OS 2.0 and if I make it for the iPad, I will have to design it for OS 3.2. I cannot change the iPhone version, because I risk some of my users with old versions of the iPhone not being able to run the app. Obvi...

Other considerations are ...
'lo all. I am in the ending portion of my app for the iPhone and found that I am in a section of the app where I want to give feedback about the status of some background process running (location manager accuracy) and want to place it in the lower left of the screen. This can tell a user how "sure" we are about the given search resu...
I'm currently developing a simple Javascript/HTML timetable application for use on mobile phones. The application includes a search facility that I would like to add autocomplete to, but doing so from within the DOM results in a pretty messy experience on Android (and I guess also iPhone). At least on Android, while the user is focused ...
In Interface Builder, you have to set the size of the tableview and position the other elements beneath that. I want the tableview to be sized to fit any number of rows and the buttons to be moved down relative to the tableview. Is it possible to do this without building the whole thing programmatically? ...

I am trying to attach an image and a pdf to an email using the MessageUI framework. I followed the MailComposer example in the Apple documentation.

I am using Core Data for an iPhone application. I have a property isChangedFromOriginal that defines if the data (for several fields - if one is changed it is the same as if all were changed) was changed from a preloaded standard.

These seem like a great combination--I'd expect to see more on at least GWT/iPhone integration, but there isn't much. I've looked through the reader example that Google made, but it doesn't seem to take advantage of many of the iPhone features. I was wondering if anyone knew of a tutorial/resource that showed how to use things like loc...
