Do a Command After an Action Has Been Completed - SpriteKit

In SpriteKit, I have a simple action for my sprite:

sprite.size = CGSizeMake(40, 10);
sprite.physicsBody =[SKPhysicsBody bodyWithRectangleOfSize:sprite.size];
sprite.position = CGPointMake(65, 230);
SKAction *changeImage = [SKAction setTexture:[SKTexture textureWithImageNamed:@"raniSlide"]];
SKAction *wait = [SKAction waitForDuration:.1];
SKAction *changeImage2 = [SKAction setTexture:[SKTexture textureWithImageNamed:@"raniStick"]];
SKAction *sequence=[SKAction sequence:@[changeImage, wait, changeImage2]];
[sprite runAction:sequence];

It changes textures, waits, then changes textures again. This is so it ducks for a certain time period. After ducking I want it to change back to its original size. When I put the code for changing size after the runAction command, it doesn't perform the first sprite.size = CGSizeMake(40, 10), and doesn't duck at all, as it stays the same size as it was in the beginning. So I was wondering how to make an if statement that when if an action has been completed, it then changes the size of the sprite.

You can't do it with an if statement, but take a look at runAction:completion:. You use it like:

[sprite runAction:sequence completion:^{
    // the action is complete, change size back
}];
