ios - How to make equal space between texts in the circular menu? -


i creating circular slider menu, using coregraphics draw control ui, here trying draw words on circumference of circle. cant able make spaces equally.

here code , output. please me give equal spaces between each word.

in drawrect

float anglestep = 2 * m_pi / [menuarray count]; float angle = degreestoradians(90); textradius = textradius - 12;  (nsstring* text in`enter code here` titlearray) {     [self drawstringatcontext:ctx string:text atangle:angle withradius:textradius];     angle -= anglestep; }

//////////

- (void) drawstringatcontext:(cgcontextref) context string:(nsstring*) text atangle:(float)angle withradius:(float) radis  { cgsize textsize = [text sizewithfont:[uifont systemfontofsize:11.0]];  float perimeter = 2 * m_pi * radis; float textangle = textsize.width / perimeter * 2 * m_pi;  angle += textangle / 2;  (int index = 0; index < [text length]; index++)  {     nsrange range = {index, 1};     nsstring* letter = [text substringwithrange:range];     char* c = (char*)[letter cstringusingencoding:nsasciistringencoding];     cgsize charsize = [letter sizewithfont:[uifont systemfontofsize:11.0]];      float x = radis * cos(angle);     float y = radis * sin(angle);      float letterangle = (charsize.width / perimeter * -2 * m_pi);      cgcontextsavegstate(context);     cgcontexttranslatectm(context, x, y);     cgcontextrotatectm(context, (angle - 0.5 * m_pi));     cgcontextshowtextatpoint(context, 0, 0, c, strlen(c));     cgcontextrestoregstate(context);      angle += letterangle; } }

output

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
