An iOS demo project showing two ways of doing async search while typing in a UITextField. Doing live searching once with standard Grand Central Dispatch calls and once with NSOperations. You can easily compare and see how it's done.
This project was the result of a discussion in CocoaHeads Bremen.
Three screens of the app in action.
- displays async search done using Grand Central Dispatch calls
- displays async search done using NSOperations
- searches the holy bible text live while typing in textfield
- download project
- compile and start
- enter text in the textfield
- switch the ways of searching
That's it! Please recognize, that the 200ms difference in the time needed to display the results is the effect of giving poptime.
