Iphone consecutive animations?

Thanks a lot. Even though it looks confusing at first sight, I think this is actually much clearer than to do the same thing with the selector method. At least I have the code presented in a linear fashion.

Thanks! – n. Evermind Apr 1 at 10:21 1 Blocks mean you don't have to store animation-state at the class level which generally leads to spaghetti code.

We created a component for chaining animation steps declaratively using blocks (CPAnimationSequence on Github). It gives you very readable code, something like this: CPAnimationSequence sequenceWithSteps: CPAnimationStep for:0.25 animate:^{ self.imageView. Alpha = 0.0; }, CPAnimationStep for:0.25 animate:^{ self.headline.

Alpha = 0.0; }, CPAnimationStep for:0.25 animate:^{ self.content. Alpha = 0.0; }, CPAnimationStep after:1.0 for:0.25 animate:^{ self.headline. Alpha = 1.0; }, CPAnimationStep for:0.25 animate:^{ self.content.

Alpha = 1.0; }, nil runAnimated:YES; Compared to the usual block-based approach (described well by Max), it has the advantage of matching the intent and its representation: a linear sequence of steps to animate. We elaborated on this topic in an article on our iOS development blog.

I may be mistaken, but the post doesn't really suggest anything else than i've already found out, i.e. To do it with the selector method. – n.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
