The objects in your search array are NSArray objects, this means that they do not respond to the selector rangeOfString: as that is a NSString method

for (NSString *sTemp in searchArray) 
{ 
   NSRange titleResultsRange = [sTemp rangeOfString:searchText options:NSCaseInsensitiveSearch];
   if (titleResultsRange.length != 0)
     [copyListOfItems addObject:sTemp];
}

should be something like:

for(NSArray *array in searchArray)
{
   // NSString *str = [array objectAtIndex:0];
    PatientInfoObject *obj = [array objectAtIndex:0];
    NSString *str = obj.id;
    // to be sure
    if( [str isKindOfClass:[NSString class]] )
    {
       NSRange titleResultsRange = [str rangeOfString:searchText options:NSCaseInsensitiveCompare];
       if( titleResultsRange.length != 0 )
       {
         [copyListOfItems addObject:str];
       }
    }
    else
    {
        // this shouldn't have happened, log something to console
        NSLog(@"**Object in array is not of type NSString**");
     }
}

You are adding array object in your searchArray.

your app is getting crash NSString *sTemp in searchArray here because sTemp contains NSArray object not NSString object.
