UPDATE: Thank you to Rixtur for the update for iOS 6. Steps updated.
This guide is adapted from Dustin Caruso’s note on viewing source in Safari for the iPhone.
Something almost every iPhone application needs is an About and Help view that allows the user to learn a little bit about the application they’re using and how it should be operated. The problem with a UITextView in Apple’s XCode and Interface Builder SDK is that you can not use rich-text styling or even bold one line over another.
One solution to this problem would be to create image files containing stylized text and then rasterize them and allow the user to page through them. The problem with this is that you can’t have tappable URLs or links embedded in the text.
David Peixotto, coding ninja and my business partner for Neutrinos, suggested we look at using a Webview or HTML view and put an imageview in the background. The trick is telling the iPhone to display a UIWebView with a transparent background. I looked around for the solution to this and came across this helpful post in the iPhone Developer SDK forums.
Step one of getting a transparent web view in interface builder is to create HTML in the controller.m for the view containing the webview that contains the CSS line: <body style=”background-color:transparent”> Inside the <head> </head> sections of the html.
Step two is to set the background color of the webview to clear or transparent: myWebView.backgroundColor = [UIColor clearColor]; Continue reading →
Some pages require an inordinate amount of time to load. For most sites, this is a big problem. Webmasters and SEO specialists know the value of a quick landing page load, because they know that netizens have short attention spans.
Dynamically built webpages, (especially applications), require time to load and visual feedback that something is happening. The most famous example is the gmail loading page:
Gmail uses a more sophisticated progress bar to represent the loading of the webpage. I found an article on yensDesign that gives some great advice on how to do this, if you want to get really fancy.
If you have a dynamically built page that you’d like to give a loading message to that doesn’t require a full progress bar, I recommend simply displaying a message and an animated gif.
I was just doing a ShareThis icon for a client I’m working with and found that how to properly style the button is poorly documented. In order to replace the whole icon and text, you are supposed to use the developer API.
I only wanted to style the text, so I was hunting for some CSS to style the text and could not find the right classes to call. Some hunting turned up the following: Continue reading →
