ios5 - How i can change iphone view background ? -

-

I used this code, however, the scene background did not change. 

  UIColor * background = [[UIColor alloc] initWithPatternImage: [UIImage imageNamed: @ "background.png"]]; [[See itself] setBackgroundColor: background]; [Background release];    
 
 
 Try:  
  self.view BackgroundColor = [UIColor colorWithPatternImage: [UIImage imageNamed: @ "background.png"]];   
 This will save your memory to create background variables.

I want to exclude newsgate packages with head in gutub comet situations in the version number along with Hewash (Newsaging 7) for the music build, but against head hash. However, I can not see a way to get the head hashes while constructing that merge. I just want to head because it's useless - we only care about merge.
