如何在UITableView中设置按钮的标题？

Question

HI I have a UITableView and I have data in my array, i have search functionality also here. this is a menu type thing. There are different dishes and user can search any dish, on the left side here is a text Field and its text is 0, when user search some dish then type some other digit in it then how to save that input in the right place, Because at that time its its cell index will be different than original. You can see this picture of my UITableView

I know this is a problem of logic but please help me I'm stuck here.

1. At first take a NSMutableArray

.h file

NSMutableArray *searchDataArray;

Now declare its property and synthesize it in your .m file

2.In your -(void)viewDidLoad alloc your search array and retain it.

1. [I am thinking that you can set searchbar and can call the search delegate]..so in

     - (void)searchBarSearchButtonClicked:(UISearchBar *)searchBar{ [sBar resignFirstResponder]; searching = YES; //A boolean for searching condition [searchData removeAllObjects]; NSString *searchText = searchBar.text; // record is a mutable array containing the cell text int count = [records count]; for (int i=0; i<count; i++) { for(int j=0;j<6;j++){ //finding the cell strings for checking recordsstr = [NSString stringWithFormat:@"%@",[records objectAtIndex:i]; //Matching string of table and search string //case sensitivity checking NSString *mainString = [NSString stringWithFormat:@"%@",[recordsstr lowercaseString]]; NSString *searchString = [NSString stringWithFormat:@"%@",[searchText lowercaseString]]; NSLog(@"main String: %@ and search string: %@ ",mainString,searchString); NSLog(@"main string lenght: %d and search String lenght: %d",[mainString length],[searchString length]); if([mainString isEqualToString:searchString] || [mainString rangeOfString:searchString].location != NSNotFound){ [searchData addObject:[NSNumber numberWithInt:i]]; NSLog(@"indext after matching: %d",i); NSLog(@"number of date in searchdata array after matching: %d",[searchData count]); break; } recordsstr = nil; } } 

In this code i am matching the cell text and search text. After finding the cell text taking array of cell index.

now when search is complete then reload your your tableview [tableview reloadData]

Now in cellForRowAtIndex check that

if(searching == YES){
for(int i = 0; i<[searchData count]; i++){
  if(indexPath.row is equal to [searchData objectAtIndex:i])
   {
  //change your text field
   }
 }
 else{
  //Without searching code
   }

May be it will help you.If any problem knock me.
