Mutex lock/unlock ........................... 25 ns
Main memory reference ...................... 100 ns             
Compress 1K bytes with Zippy ............. 3,000 ns  =   3 µs
Send 2K bytes over 1 Gbps network ....... 20,000 ns  =  20 µs
SSD random read ........................ 150,000 ns  = 150 µs

预先说明

目前游戏里面出售的道具，都属于consumable products（消耗性商品），下面的说明流程都是针对这类商品的。别的类型商品处理方法，不完全一样。

注册支付接口回调

app启动的时候即注册支付队列消息的回调者，这个回调者应该是一个单体类，保证在app整个生命周期都存在。ios会回调之前未处理完成的订单。

- (id)init {
    if((self = [super init])) {
        [[SKPaymentQueue defaultQueue] addTransactionObserver:self];
 }

For those who prefer to avoid solutions like iCloud Photos and Dropbox for backing up photos, you can sync your iPhone photos with Syncthing. To do this, you'll need two things:

• Möbius Sync is, to my knowledge, the only actively-maintained Syncthing client for iOS. It's free to sync up to 20 MB, and only $4.99 (one-time) to remove that limit.

• PhotoSync is a nifty iOS app for syncing photos to a number of different destinations. It's free for low-quality
