JavaScript buffer motion implementation method (2 example), using javascript2
This article describes how to implement JavaScript buffer motion. We will share this with you for your reference. The details are as follows:
Implementation Principle(Target distance-current distance)/base = speed (the larger the movement distance, the smaller the speed, the inverse ratio of the Movement distance to the speed)Copy

8.2 uiactionsheet
For this class, I just analyzed a piece of code:
// Open a dialog with two custom buttons
Uiactionsheet * actionsheet = [[uiactionsheetAlloc] initwithtitle: @ "uiactionsheet
Delegate: SelfCancelbuttontitle: NilDestructivebuttontitle: Nil
Otherbuttontitles: @ "button1 ",@ "Button2", nil];
Here, both the cancel button and destructive button can be nil or not nil, or nil. The other is not, but we need to know the order of the button index. If there is only one, so t

and a small old generation. The reason is that most of the short-term objects can be recycled as much as possible to reduce the medium-term objects, while the old generation will store the long-term surviving objects as much as possible.
Fragmentation problem caused by a small heap
The heap is not compressed because the concurrent collector of the old generation uses the marking and clearing algorithms. When the collector recycles the object, it merges the adjacent space and assigns it to a la

Idea: If we were to fill 0 in front of the number , we would find that the N-bit all 10 binary number is actually N from 0 to 9 of the full array. That is to say, we arrange each digit of the number from 0 to 9, and we get all the 10 binary numbers. 1 /**2 *ch Storing numbers3 *n n Number of digits4 *index Count Value5

This paper illustrates the implementation of JavaScript buffering motion. Share to everyone for your reference, specific as follows:
principle of realization : (Target distance-current distance)/cardinality = speed (the larger the distance, the smaller the motion distance and the speed is inversely proportional)
Copy Code code as follows:
(500-odiv.offsetleft)/7 = Ispeed;
Note : When the calculated speed is fractional, it needs to be rounded;
Copy Code code as follows:
short-term objects can be recovered as much as possible, reducing medium-term objects, while older generations store long-lived objects.Fragmentation problems caused by smaller heapsThe heap is not compressed because the old generation of concurrent collectors uses tags and clears the algorithm. When the collector recycles, he merges the adjacent space so that it can be assigned to a larger object. However, when the heap space is small, after a period of time, "fragmentation" occurs, if the con
