UISearch重新排列indexpath.row

Question

I have a UiSearchBar implemented in my TableView , and I also have two NSArray s, one for title and one for description. When I search through the array of the titles, it returns the right search, but when I click on a row that the search came with, I get "row 0" if I click on the first row. My question is how to make a connection between the two arrays so that when the search rearranges the titles based on the user search, the description array corresponds to the same row the title is at.

Answer 1

Simply do not use two NSArray s, but just one with custom NSObject objects:

@interface SomeObject : NSObject {
    NSString *_title;
    NSString *_description;
}

- (BOOL)matchesKeywords:(NSString *)keywords;

@end

Then you have all your information stored in one class, the way Obj-C is meant to be. You can easily perform the search because the objects itself sort of knows whether it matches a given keyword, so when you'd like to change SomeObject you can easily manage those changes in the class itself.

Answer 2

我确实将两个数组合并为一个，但这使tableviewcell的加载速度变慢，因为该单元格同时包含标题和描述

Answer 3

I had this problem once So for the quick fix I did this: In the header: BOOL usingFilterArray;

Where you switch between the complete dictionary and the filtered one simply set the above BOOL to NO and YES respectively.

then in didSelectRowAtIndexPath use "if" statement to check the sate of the usingFilterArray. Rest should be pretty easy. (Let me know if you still need help) Just one thing when you perform the search after the filter Dictionary is hydrated if you cancel the search you need to make sure to run this or your app is going to crash as the hydrated dictionary will not have any object in it. (I assumed you cleaned the filtered Dictionary)

- (void) searchDisplayControllerDidEndSearch:(UISearchDisplayController *)controller {
        [self.tableView reloadData];
 } 

Mate this is just a quick fix.
