Swift rubber band and swift rubber band

Today, I saw a good ios game source code on the ios tutorial online. This is the source code of a rubber band flying plane with swift. The game source code is more detailed, you can study it.

How can I use a rubber band to launch a plane?

Place the rubber band on the Plane Gap, stretch the rubber band to the plane, then loosen it, and then fly out.

I really don't know how to answer this question. Do you dare to ask whether LZ is a buy suit or just a hand-made suit? If it is a suit, Please carefully refer to the Manual. If it is a hand-run, you need the following materials: rubber band, preferably the kind of Common yellow, but you need to buy a m or so (it seems that the five gold stores are selling ), the wooden stick is about 4/1 m long (this looks like I have never seen it sell it separately, but I can use the wooden board to sell it myself) blow-up paper (usually sold in a stationery store) and the kind of propeller to glue, the diameter depends on the rubber band. Generally, it is OK when the length of the body is 3/1.
