• First we'll lay out the layout using Sizeclass:

• Connect here:

@property (weaknonatomicIBOutletUIButton *bird;@property (strongnonatomic) IBOutletCollection(UIImageViewNSArray *ices;

For ice, because we have 4 blocks of ice here, so we're directly connected to an array.

• Lazy Loading a Uidynamicanimator

@property (strongnonatomic) UIDynamicAnimator *animator;- (UIDynamicAnimator *)animator{    if ( !_animator) {        _animator = [UIDynamicAnimator new];    }    return _animator;}

• Next, we give a listen to the bird's Click event

- (ibaction) Birdaction: (ID) sender{//Add gravity to birds and ice    Nsmutablearray*TEMPARRM = [NsmutablearrayArray]; [Temparrm AddObject: Self. Bird]; [TEMPARRM Addobjectsfromarray: Self. Ices];    Uigravitybehavior *gravity = [[Uigravitybehavior alloc] INITWITHITEMS:TEMPARRM]; [ Self. AnimatorAddbehavior:gravity];//Add collisions to birds and iceUicollisionbehavior *collision = [[Uicollisionbehavior alloc] INITWITHITEMS:TEMPARRM]; [Collision Settranslatesreferenceboundsintoboundary:YES];//Add screen edge collisionsUibezierpath *path = [Uibezierpath bezierpathwithrect: Self. View. Bounds]; [Collision addboundarywithidentifier:@"Boundstest"Forpath:path]; [ Self. AnimatorAddbehavior:collision];/** uipushbehaviormodecontinuous, continuous force uipushbehaviormodeinstantaneous instantaneous force * *    //Add thrust to the birdUipushbehavior *push = [[Uipushbehavior alloc] initwithitems:@[ Self. Bird] mode:uipushbehaviormodeinstantaneous];//direction of forcePush. Magnitude=5.0; Push. Angle=2* M_PI; [ Self. AnimatorAddbehavior:push];}

Look at the effect:

Can simply realize this little game, we can make the rest of the functions of their own perfect. Thank you
