Backup your Xcode project

April 24, 2009 § Leave a comment

Xcode does include Snap Shot, a utility you can save the changes like version control SVN.

This is not reliable. It’s nice to keep it as extra saving mechanism.

The most reliable way to back up your developer version is using version control. Usually version control requires server support. It is very likely you would pay for private SVN for monthly use.

Git is ideal version control for single developer. It works on Mac. It is free and open source. It backup your changes on your local machine. It is easy to use.

Google map on UIWebView

April 10, 2009 § 1 Comment

It seems to be common problem in getting map to display fast and well on UIWebView.

Any javascript running in the UIWebView will be terminated after 5 sec. Calling Google map API directly to display the entire map or any attempt to zoom and pan around will be slow, even on 3G network.

A good approach will be using static map image, or preload map images on web server.

Open source mapping alternatives:
