！ I wrote all the code inside the material code, the comments are complete, easy to learn

Look first.

Game rules

1-"On the screen?" There are four rows of bricks.
2-"Tap the screen to start the game
3-"When the game starts, the ball goes up?"
4-"ball and brick impact can smash bricks and rebound
5-"ball with the top of the screen, the right side, the left side of the collision will rebound
6-"ball and baffle collision will rebound
7-"Moving around?" the finger can move the bezel.
8-"small ball from the bottom of the screen to fall out of the game end

Development steps

1-"New Item"
2-"Building an Interface"
Get the boundary? Face like and monitor screen events (Storyboard Setup interface, off-line)
3-"Code implementation
Tap the screen to make the ball move (game clock, refresh position)
Brick Collision Detection (hidden after collision)
Drag the bezel to change the ball direction (get the drag gesture speed, change the ball speed)
Winning and losing judgment and resetting the game (the minimum value of y in the position of the ball is greater than the screen y maximum)
