Random SpriteKit texture switch statement not working correctly - ios

Question

I'm currently working in SpriteKit in Objective C, and I'm trying to set a number of random textures in a switch statement to 9 different SKSpriteNodes. Currently, this section of my code looks like this:
int randomCard = arc4random_uniform(13);
switch (randomCard)
{
case 0:
staveCard = [SKTexture textureWithImageNamed:#"Card_C.png"];
break;
case 1:
staveCard = [SKTexture textureWithImageNamed:#"Card_D.png"];
break;
case 2:
staveCard = [SKTexture textureWithImageNamed:#"Card_E.png"];
break;
case 3:
staveCard = [SKTexture textureWithImageNamed:#"Card_F.png"];
break;
case 4:
staveCard = [SKTexture textureWithImageNamed:#"Card_G.png"];
break;
case 5:
staveCard = [SKTexture textureWithImageNamed:#"Card_A.png"];
break;
case 6:
staveCard = [SKTexture textureWithImageNamed:#"Card_B.png"];
break;
case 7:
staveCard = [SKTexture textureWithImageNamed:#"Card_C2.png"];
break;
case 8:
staveCard = [SKTexture textureWithImageNamed:#"Card_D2.png"];
break;
case 9:
staveCard = [SKTexture textureWithImageNamed:#"Card_E2.png"];
break;
case 10:
staveCard = [SKTexture textureWithImageNamed:#"Card_F2.png"];
break;
case 11:
staveCard = [SKTexture textureWithImageNamed:#"Card_G2.png"];
break;
case 12:
staveCard = [SKTexture textureWithImageNamed:#"Card_A2.png"];
break;
}
faceDownStaveCard1 = [SKSpriteNode spriteNodeWithTexture:staveCard];
faceDownStaveCard2 = [SKSpriteNode spriteNodeWithTexture:staveCard];
faceDownStaveCard3 = [SKSpriteNode spriteNodeWithTexture:staveCard];
faceDownStaveCard4 = [SKSpriteNode spriteNodeWithTexture:staveCard];
faceDownStaveCard5 = [SKSpriteNode spriteNodeWithTexture:staveCard];
faceDownStaveCard6 = [SKSpriteNode spriteNodeWithTexture:staveCard];
faceDownStaveCard7 = [SKSpriteNode spriteNodeWithTexture:staveCard];
faceDownStaveCard8 = [SKSpriteNode spriteNodeWithTexture:staveCard];
faceDownStaveCard9 = [SKSpriteNode spriteNodeWithTexture:staveCard];
When I run this on the simulator, all of the sprite nodes display the same random texture. However, I want the textures to be random for each sprite node, picking a different node each time.
Something like:
pick random texture from switch statement
add to first sprite node
pick random texture from switch statement
add to second sprite node
etc.
Is anyone able to help with this?

Your program's flow now is:
Create random number
Pick 1 texture
Set that texture to every node
It should loop the first 2 steps the same amount of times as nodes present. Try something like:
for (int i = 0; i<9; i++) {
int randomCard = arc4random_uniform(13);
switch (randomCard)
{
case 0:
staveCard = [SKTexture textureWithImageNamed:#"Card_C.png"];
break;
case 1:
staveCard = [SKTexture textureWithImageNamed:#"Card_D.png"];
break;
case 2:
staveCard = [SKTexture textureWithImageNamed:#"Card_E.png"];
break;
case 3:
staveCard = [SKTexture textureWithImageNamed:#"Card_F.png"];
break;
case 4:
staveCard = [SKTexture textureWithImageNamed:#"Card_G.png"];
break;
case 5:
staveCard = [SKTexture textureWithImageNamed:#"Card_A.png"];
break;
case 6:
staveCard = [SKTexture textureWithImageNamed:#"Card_B.png"];
break;
case 7:
staveCard = [SKTexture textureWithImageNamed:#"Card_C2.png"];
break;
case 8:
staveCard = [SKTexture textureWithImageNamed:#"Card_D2.png"];
break;
case 9:
staveCard = [SKTexture textureWithImageNamed:#"Card_E2.png"];
break;
case 10:
staveCard = [SKTexture textureWithImageNamed:#"Card_F2.png"];
break;
case 11:
staveCard = [SKTexture textureWithImageNamed:#"Card_G2.png"];
break;
case 12:
staveCard = [SKTexture textureWithImageNamed:#"Card_A2.png"];
break;
}
switch (i)
{
case 0:
faceDownStaveCard1 = [SKSpriteNode spriteNodeWithTexture:staveCard];
break;
case 1:
faceDownStaveCard2 = [SKSpriteNode spriteNodeWithTexture:staveCard];
break;
case 2:
faceDownStaveCard3 = [SKSpriteNode spriteNodeWithTexture:staveCard];
break;
case 3:
faceDownStaveCard4 = [SKSpriteNode spriteNodeWithTexture:staveCard];
break;
case 4:
faceDownStaveCard5 = [SKSpriteNode spriteNodeWithTexture:staveCard];
break;
case 5:
faceDownStaveCard6 = [SKSpriteNode spriteNodeWithTexture:staveCard];
break;
case 6:
faceDownStaveCard7 = [SKSpriteNode spriteNodeWithTexture:staveCard];
break;
case 7:
faceDownStaveCard8 = [SKSpriteNode spriteNodeWithTexture:staveCard];
break;
case 8:
faceDownStaveCard9 = [SKSpriteNode spriteNodeWithTexture:staveCard];
break;
}
}
This is just an idea of how the flow should be, please optimize the code. Good luck!
