This does not, at least not currently supported. ios is a single task, can not write their own background. symbian kernel supports the c / s of.

But there is a local nitifation ios can also register system events, or custom events, but no symbian c / s so flexible and powerful. .

Break it

Crack was not on the app store.

This needs to be considered.

Now demand is demand: all have events are a task, each task has its own priorities too, which was similar to the realization of a symbian AO mechanism. Not done iphone, iphone want to know an asynchronous framework.

Meaning not a single process alone is not a single-threaded tasks, but can only be activated at the same time a third-party application. (Apple's own without this restriction, which is in ios single task you can have in your program is running listen to music without problems)

You need to complete the task can use a number of parallel threads to execute complete.

Upstairs that solutions should be impossible to achieve the landlord needs. . symbian a0 scheduling there ao scheduling, dispatching, when each task has prioritized. Once you add a task to the ao scheduling, then you have no way to manipulate the corresponding ao when executed. Only to asynchronous cancel.

The landlord needs to be is to achieve a similar ao scheduling ..

You can only use one thread to achieve this ao scheduling, and then all events are added to this thread to go inside, the event has a priority to be set, as well as the callback function. Remember all, whether it is networking, or ui action event, then in this thread inside of each event as a task. Then in this thread which to perform all the tasks, then the task is completed (failed or successful completion of are called), the use of a callback function notifies the caller ...

But the scheduling rules need to take the time to consider. . .

You can consider the thread's runloop inside fuss.
