Title: Custom UITable Sorting not working on device
Post by: DuckOfDoom on May 08, 2013, 04:38:12 AM

I had to implement sorting items by their price for one of my UITables. I named all of GameObjects in that table according to their price(like 5100), but because you can't compare strings as integers(2111 is bigger than 11111 string-style), I had to implement a comparison of strings as integers using int.TryParse. Here is the example methods(in class MiscTools, doesnt matter):

1. public static int CompareTransformsByNames(Transform first, Transform second)
2. {
3.         return GetIntFromString(first.name).CompareTo(GetIntFromString(second.name));
4. }
5.  
6. public static int GetIntFromString(string number)
7. {
8.         int output;
9.  
10.         if (!int.TryParse(number, out output))
11.         {
12.                 Debug.Log(string.Format("Unsupported string formant in sorting: {0}", number));
13.                 return 0;
14.         }
15.                 return output;
16. }

And this is how it is used:

1. myTable.children.Sort(MiscTools.CompareTransformsByNames);
2. myTable.Reposition();
3.  

I also tried LINQ approach:

1. myTable.children.OrderBy(x => MiscTools.GetIntFromString(x.name));
2. myTable.Reposition();
3.  

Both variants work like a charm in editor, table is sorted right, but on devices(both iOS and Android) it does no sorting at all, without any exceptions or anything. I know the only place the table gets sorted is line 66 of UITable.cs(

1. if (sorted) mChildren.Sort(SortByName);

) but "sorted" flag is off on all tables.

What could possible be a reason of such strange behaviour on devices specifically?

If you append zeroes in front, everything works as it should.

Thanks, ill try that. I'm just curious about why the behaviour differs in editor and on device.
