Spacing sprite onscreen - ios

Question

Hi all I'm hoping someone can tell me how to decrease the spacing between sprites added from an array at the moment they are evenly spaced and centered but I need to decrease the width between the sprites
the whole block of code just incase is kind enough to test the spacing
int images = 5
for(int i = 0; i < images; ++i)
{
///load same ammount of spriteimages as images
SKSpriteNode *sprite =
[SKSpriteNode spriteNodeWithImageNamed:#"Null.jpg"];
sprite.name = #"sprite.name =Sprite%d",[NSString stringWithFormat:#"%i",i];
NSLog(#"***sprite.name %#",[NSString stringWithFormat:#"%i",i]);
///spriteSpacing
float offsetFraction = ((float)(i + 1)) / (images + 1);
float widthOfScreen =self.frame.size.width;
sprite.position = CGPointMake(widthOfScreen * offsetFraction,self.frame.size.height/2 +200);
[self addChild:sprite];
}

Answer 1

try this and see what happens
float widthOfScreen = self.frame.size.width + 100.0;

Answer 2

in the end I did this
float padding = 100.0f;
int blockWidth = [SKSpriteNode spriteNodeWithImageNamed:#"Null.jpg"].size.width;
float xOffset = (self.frame.size.width - (blockWidth * images + padding * (images-1))) / 2;
//float xOffset = (self.frame.size.width - (blockWidth * numberOfBlocks + padding * (numberOfBlocks-1))) / 2;
float StartPoint = xOffset+blockWidth/2;
for(int i = 0; i < images; ++i)
{
SKSpriteNode *sprite = [SKSpriteNode spriteNodeWithImageNamed:#"Null.jpg"];
///set start point of 1st sprite to load
if (i>0&&i<images)
{
StartPoint = StartPoint+ blockWidth+padding;
}
//increment sprite position
else if (i==images)
{
StartPoint = StartPoint+ blockWidth;
}
sprite.position = CGPointMake(StartPoint, self.frame.size.height * 0.8f);
[self addChild:sprite];
}
