title: working with large sprite sheets on iphone
body: <p>I am trying to use sprite sheet animation in my application.
  The first POC with a small sprite sheet worked fine but as i change the sprite sheet to a bigger one, i get "check_safe_call: could not restore current frame" warning and the application quits.</p>
  
  <p>A quick search revealed that this problem meant my app is taking too much memory or the image is too huge in dimension.</p>
  
  <p>My image is 4.9 Mb and dimensions are 6720 * 10080 (oops!!). i read that iphone allows maximum 3 Mb image with dimensions up to 1024 * 1024. Also that the sprite sheet image dimensions should be a power of two. </p>
  
  <p>So please let me know how i can use a sprite sheet this big.</p>
  
  <p>One approach could be to cut the sprite sheet into many smaller sprite sheets and use them one at a time.</p>
  
  <p>Please suggest if you know any other/better approach to accommodate bigger sprite sheets and whether the problem with my sprite sheet is size (4.9 Mb) OR dimensions (6720 * 10080).</p>
  
  <p>(Just FYI, i am not trying to play a movie so using MP4 file instead is not an option for me. i need to animate the sprite sheet based on accelerometer input and i have been able to achieve that in my POC with smaller sprite sheet.)</p>
  
  <p>Thanks,
  Swapnil</p>
