iphone - Closing an app in the background -

-

Suppose I have an iOS app that is actually running in the background (for one of many legal reasons, such as background audio, requested time, etc.). What could happen if the OS shut down this app instead of running or suspending this race? How can I avoid them? How can I use the public API (inside this app) How can I trigger?

Your app can be killed, it uses too much memory, if it EndBackgroundTask: , the timeout handler ( beginBackgroundTaskWithExpirationHandler: is called while specifying), if the user hits it clearly, if the app throws an exception , Call exit , triggers an EXC_BAD_ACCESS or other signal, and so on. There are probably other reasons too.

To avoid these, do not use too much memory, call Endbacker Task: Create an app that will not want the user want kill, and the exception Do not throw, call exit , use invalid storage locations, and so on.

There is no way to do this so that the user "" For others, you can allocate multiple memory, refuse to call endBackgroundTask: , [NSException raise: ... format: ...] , Call exit , or create and follow the random garbage signals. You probably should not do any of these, though.

qt - switch/case statement in C++ with a QString type -

-
I want to use switch-case in my program but the compiler generates an error. How can I use the switch statement with QString ? The compiler gives me this error: The expression of the switch type 'QString' is invalid My code is as follows : boolStopWord (the word QString) {bool flag = false; Switch (word) {case "the": flag = true; break ; "On" case: flag = true; break ; Case "in": flag = true; break ; Case "your": flag = true; break ; Case "near": flag = true; break ; Case "all": flag = true; break ; Case "this": flag = true; break ; } Return flag; } How do I use the switch statement with a Caststring ? You can not use the switch statement in C ++ language with integral or enum types. You can formally enter the square type of object in the switch statement, but this means that the compiler will look for a user-defined conversion to convert it to an integral or enum type.

What is a Python equivalent for Ruby's define_method , which is the dynamic generation of class methods will allow? (As can be seen in Wikipedia) Functions are first-class objects in Python and assign them The properties of a class or an example can be a way of doing the same thing as a Wikipedia example: colors = {"black": "000", "red": "F00", "green": "0f0", "yellow": "ff0", "blue": "00f", "magenta": "fff", "cyan": "0ff", "white": " FFF "} Class MyStream (ARR): Pass for Name, Code in colors.iteritems (): def _in_colour ( W code = code): return '& lt; Span style = "color:% s" & gt;% s & lt; / Span & gt; ' % (Code, self) setter (histrive, "in_" + name, _in_ color)
