ios - Improving UIWebView initialization time -


my company uses uiwebview display ads. issue i'm having initializing uiwebview appears expensive; profiling time profiler shows [uiwebview alloc] initwithframe:cgrectmake(0,0,500,500)] take 31–40ms. enough cause noticeable frame drops in games running @ 60 fps.

is there way workaround slow initialization time? current ideas create uiwebview when app launches (but before gameplay has started), , reuse (potentially creating pool of them reuse, how uitableviewcell works) or try , see if wkwebview has better performance.

here findings:

  1. wkwebview not initialize faster. creating wkwebviews took similar amount of time creating uiwebviews (in 1 test did, took 46ms create 2 wkwebviews.
  2. the first web view created takes longer create subsequent web views. first 1 takes 31–42 ms; subsequent ones take ~11ms create. news here creating first web view when e.g. app launches allows future webviews created more cheaply, avoiding 40ms hit while game running.
  3. creating pool of uiwebviews solution use case. creating webviews @ app launch , reusing them, avoid causing frame drop while game running.

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 ...
