ios - ios8: any method called prior to an app quitting? -


this question formulate action plan.

background: cannot count on silent pushes app not running. need know recent presence of app running, without repeatedly posting database. ideally, when app running, irrelevant app responds properly, when force-quit, have not reference when happened.

in ios8, seems have no guaranteed method hook allow ensure can thing prior app being shut-down. hooks can figure manage enter background or when resign active mode. hit db on , on user can re-enter app many times. not ideal.

so question: there other hooks can manage grab last-ditch moment before app force-quit fire off quick async db update?

utf 8 - split utf-8 string into bytes in python -

i trying split utf-8 string bytes in python 3. problem is, when use bytearray, byte, encode etc functions array size of element 14 bytes, not 1 byte expected. need split text file sequence of bytes , send them byte after byte using sockets. tried this: infile = open (file, "r") str = infile.read() byte_str = bytes(str, 'utf-8') print("size of byte_str",sys.getsizeof(byte_str[0])) print gives me 14, need 1... suggestion? quoting official documentation : sys.getsizeof(object[, default]) return size of object in bytes. object can type of object. built-in objects return correct results, not have hold true third-party extensions implementation specific. only memory consumption directly attributed object accounted for, not memory consumption of objects refers to. if given, default returned if object not provide means retrieve size. otherwise typeerror raised. getsizeof() calls object’s __sizeof__ method , adds ...
