ios - Xcode FPS Debug Gauge always show 0 FPS -


i have game in xcode 6.1.1 using opengl es 3.0, targeting ipad air. when capture opengl es frame, fps number , shader program time show 0.

i have enabled "gpu frame capture" option in project scheme. frame rendering called cadisplaylink in non-main thread.

how can correct fps nubmer , program time?

i came across similar issue. if implement uiviewcontroller setting eaglcontext layer xcode not display measurements except memory , cpu performance,instead of should use glkviewcontroller implementation.

for example:

replace below line 

   @interface myrenderingview : uiviewcontroller <...>{...}

with

   @interface myrenderingview : glkviewcontroller <...>{...}

this makes difference.

another way:

use "xcode->opendevelopertool->instruments->gpu driver" run app, tool displays fps , other gpu information needed.

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 ...
