Note 2 : After the refresh is successful, clear the Self.tabBarItem.badgeValue

Note 3 : Nstimer timer, if the main line is impersonating in the processing of other events, such as always scrolling, then the timer will not start, should tell the main thread, a little time to the timer, that is, modify Mainrunloop mode of the timer in

Note 4 : When you get the unread readings, you should also APP set the corresponding number on the icon

Note 5 : After the above method is complete, there is a problem once APP into the background, the timer does not work, it will not be able to obtain the micro-Bo unread, displayed in APP icon, you need to re-enter the background of the program to open background tasks

Note 6 : The time to open the background task below is still indeterminate and depends on the operating system CPU , memory and so on, may also be killed by the system.

Note 7 : To get more time, it's best to tell the operating system APP Background tasks are required to enter the background, Info.plst Set Background mode in: Required Background Modes ==app plays audio or streams audio/video using AirPlay , but it's still not sure how long it will run in the background.

Note: To write a control to reach Frame appears a Frame the effect, for testing, you can write the outside code first ( proxy method for TableView )

Note: Body Frame the calculation!!!

7.5 Modifying code in Hwhomeviewcontroller
