工作注意点

一：infoplist文件配置

集成google-cast-sdk后, 需要在infoplist里加入以下键值对, 不然上传不了appstore, 最近打包注意一下
NSBluetoothPeripheralUsageDescription
The App needs bluetooth access to scan for nearby Cast devices.

疑问：

   [UIView animateWithDuration:2.0 animations:^{
        self.alpha = 0;
        self.transform = CGAffineTransformScale(self.transform, 0.2, 0.2);
    } completion:^(BOOL finished) {
        [self removeFromSuperview];
    }];
