[MobClick startWithAppkey:APPKEY reportPolicy:SEND_INTERVAL channelId:APPChannel];
reportPolicy:是设置友盟上报机制，一下是其参数说明：
typedef enum {
REALTIME = 0, //实时发送 (只在测试模式下有效)
BATCH = 1, //启动发送
SEND_INTERVAL = 6, //最小间隔发送 ([90-86400]s, default 90s)
// deprecated strategy:
SENDDAILY = 4, //每日发送 (not available)
SENDWIFIONLY = 5, //仅在WIFI下时启动发送 (not available)

} ReportPolicy;
