   Hi, I use an xml file to store the level info for my game. the xml looks like

   <level1 num="5" hp="25" file="snow"/>

   I can get the value for num and hp successfully, but the problem is about string, the code is

   int num = [[attributesDict valueForKey:@"num"] intValue];
   ...
   NSString *file = [attributesDict valueForKey:"file"];
   Sprite *sprite = [Sprite spriteWithFile:[file stringByAppendingPathExtension:@"png"]] // something wrong here

   And I have tested [[file stringByAppendingPathExtension:@"png"] isEqualToString:@"snow.png"]] // is true

   so, what is the problem? help me plz!

   are you sure you included "snow.png" in your project. Try:

   Sprite *sprite = [Sprite spriteWithFile:@"snow.png"];

   and see if that works, if not then you are missing a file probably.

   Also, when having a problem, post what error you get - look in the console.

   I am sure, Sprite *sprite = [Sprite spriteWithFile:@"snow.png"];// works pretty well

   ok just to clarify, you are saying:

   Sprite *sprite = [Sprite spriteWithFile:@"snow.png"];// works

   and:

   [[file stringByAppendingPathExtension:@"png"] isEqualToString:@"snow.png"]] // is YES

   but:

   Sprite *sprite = [Sprite spriteWithFile:[file stringByAppendingPathExtension:@"png"]] // doesnt work

   ??

   again - what do you mean by "doesnt work"? What does the console say? Does it freeze or crash? At what line? Does it run, but the sprite just doesnt show up? "doesnt work" isnt very helpful.

   ok, the console says nothing, and the project freezes, just at the line

   Sprite *sprite = [Sprite spriteWithFile:[file stringByAppendingPathExtension:@"png"]]

   it is quite strange.
