, and the constraints of the layout system, complex animations, especially UIView series or CALayer series of animations, are not possible. The only thing that seems possible now is frame animation, which WKInterfaceImage can be achieved by setting up an image with more than one image, or replacing an image with a timer timing. While Apple's own example has been animated in this way, the storage and power consumption of the device can be challenging, and it needs to be tested and observed after

In the previous note, I mentioned the usage of mpmovieplayercontroller. The effect of the player made by mpmovieplayercontroller is really monotonous, although I added album photos and lyrics for song response in the project, the effect was still unsatisfactory. I saw the mpmusicplayercontroller class in "iPhone development cheat book" and found that a player only needs three lines of core code, which is really speechless. Then I used the mpmediapicke

In Part 1Of this series of articles we drew some simple graphic primitives onThe iPhone display. In this article we are going to look at how to doSome simple animation. The goal of this example is to create a 2D ballThat bounces around the iPhone screen. First of all we need an object to represent a point in our 2 dimen1_coordinate system. ThePoint2dObject will t

You can also find a lot of hardware that could not be discovered by the system, including the camera, the Bluetooth adapter can function properly. The screen display becomes clearer after you have your own graphics card driver. You can also adjust the screen brightness sound, keyboard backlight and so on through the keyboard function keys. You can also make a simple switch between your Mac system and Windows.This article is from

Topic:Orchard has a bunch of apples, a total of n head (n greater than 1 less than 9) bears points, the first small east, it divided the apples into n parts, one more, it threw away this one, took one of their apples, and then the second bear repeated the process, that is, to divide the n parts, throw one and then take a copy, And so on until the end of the bear is like this (the last bear can take away after the 0, but also a n share). Ask at least how many of these apples were at the beginning
