！

The code contains all the code I've written, and I've got a full stare. 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 upward?"
4-"ball and brick impact can smash bricks and bounce back
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
Click on the screen to make the ball move up (game clock. Refresh location)
Collision detection of bricks (hidden after collision)
Drag the bezel to change the ball direction (get the drag gesture speed, change the ball speed)
Winning and losing inference and resetting the game (the minimum value of y in the position of the ball is greater than the screen y maximum)
