iOS Background fetch mode -


What is the "Background Fitch" mode about iOS? Apple documentation is quite common here: "... at the right time, the system gives the background execution time to the system ..." "... the only app that provides important services to the user ...

  1. Is there a time limit (clearly specified or empirical) in which the system controls the app in the background? (I can tolerate a 5-minute interval)
  2. Does anyone applying for "background fetch" permission

    Note: For a short time to call a requirement (eg, 10.30am to 15:15 pm, ...) and show results in a notification (server side push Without the use of the notification). Since it is practically a pre-scheduled local notification to bind some custom code, so I was wondering whether to run "background-fetch" mode for calling at the time required Can work from

    I used to bring background with push notifications. When the push notification arrives, the application background Will start downloading new data with the decision. It gives 30 seconds

    I think you will be able to use it at regular intervals in your case, but are not sure that you can register it with local information and show it. When a user is in the background

Java - Error: no suitable method found for add(int, java.lang.String) -

I'm in the middle of homework work and I'm stuck. At this point in my code, I think that I should have a GUI window that opens and allows me to type "inserted text number".

Add (index, element); And I can not seem to get past it, there is no suitable method for the error "add (int, java. string string)". Code is below, please advise.

c++ - static template member variable has internal linkage but is not defined -

Yes, I know, there is a question with almost the same title, but it refers to a different situation. Error message) In my case, I have a .cpp file with a big named designation name (implementation details). There is a property class template with a static data member in that name space, which I need to access from outside the unknown namespace. I give it a little bit of meat: file.hpp namespace Bar {template & lt; Typename A & gt; Struct foo {static_assert (is_same & lt; a, float & gt; :: value} is_same & lt; a, double>: value, ""); Fixed zero set_static_var (a const & x); // ...}; } and file.cpp namespace {template & lt; Typename A & gt; Struct foo_traits {// supports the implementation of several static code bars: foo & lt; & Gt; Fixed A data; }; The template's & lt; & Gt; Float foo_traits & lt; Float & gt; :: datum; // No change if this is in the global namespace template & lt; & Gt; Doub...
