I'm programming an app for the iPhone. I'm not very good with loops just yet. How do I shorten this code into a for loop?

if(CGRectContainsRect([space1 frame], [box frame])){

  space1.image = [UIImage imageNamed:@"box.png"];
 }
 else if(CGRectContainsRect([space2 frame], [box frame])){

  space2.image = [UIImage imageNamed:@"box.png"];
 }
 else if(CGRectContainsRect([space3 frame], [box frame])){

  space3.image = [UIImage imageNamed:@"box.png"];
 }
 else if(CGRectContainsRect([space4 frame], [box frame])){

  space4.image = [UIImage imageNamed:@"box.png"];
 }
 else if(CGRectContainsRect([space5 frame], [box frame])){

  space5.image = [UIImage imageNamed:@"box.png"];
 }
