How can i achieve this smart search in obj c

In my iphone app i have a search screen with UISearchDisplaycontroller uisng this against each scopeBar key words we can filter the search result, But using only this scopeBar buttons i couldnt reach my requirement.

See, I have a list of members, I need to search members based on state, country, city, name. and i should display these search types in a bar (say scopBar).

After selecting a scopeBar button(say Country)if we type 'India' in the search bar it should display all the members of that country. How can i achieve these kind of search ? I have tried many search tutorials, But those didnt help me. Please help me out.

Thanks in Advanced!

Solution

  • As per Apple's Sample code, we can use 2 arrays during search, 1 actual, and 2nd is filtered array as in example reference :

    http://developer.apple.com/library/ios/#samplecode/TableSearch/Listings/MainViewController_m.html#//apple_ref/doc/uid/DTS40007848-MainViewController_m-DontLinkElementID_6

    But in your case, we are requiring 3 arrays, third array will be local array (let's call scopedFilteredArray) during filteration.

    1. Search all objects by scope bar : Using Predicate (contained by scopedFilteredArray, from actual array).

    2. Search filtered objects from scopedFilteredArray and save them in filteredArray for display.
