The beauty of order generation.
1. appear successively with a certain amount of Delay
1. Go out clockwise and rotate back counterclockwise.
2. Come back first
3. Click the set button to rotate clockwise and then clockwise.
1. What I did is much simpler than above, but it only delays moving. (The order of going out may be reversed. It should be advanced first-in-first-out ).
1. With the same amount of latency, one card is placed into the heap.
2. With the same amount of latency, one card is coming out of the card stack.
2. Unequal Delay
1. This is from ios8. it is faster in the middle and slower on the side. (It seems to be simpler than IOS7. I remember IOS7 is more complicated .)
1. Multiple items appear in the same way, and a little delay will be very nice.
2. The appearance of each thing is also complex, with gradient, size, and displacement changes.
1. As mentioned above, every one of them is the same animation, falling and rebounding, but when there are multiple things together, a little delay will be very beautiful.
1. The scaling effect is similar.
