Here is my MultiBrowser class project. It has 3 panes, any bumpable to full screen, 1 with video, refresh on demand or every 4 min.
The base MultiBrowser class:
- is designed for iPad and landscape only
- has the first web view dedicated to video, and so not participating in refreshes
- provides for a sub class to position the first web view off screen while video loads (e.g. x = -500)
The sample MyMultiBrowser sub class:
- shows a simple (8 line) sub class
- changes the URL of the second web view
- changes the threshold when its javascript runs to be appropriate to that site
- adds javascript to customise the web view by scrolling past the site headers
A full sub class (such as my News, which has 140 lines) would implement custom delegates to do things such as:
- re-size the video to fit the web view
- start the video playing
- crop sites to just relevant portions
- detect and flag changes such as forum posts and replies
- delete cookies and data on exit
.... (for more classes in this family see... Classes )
