objective c - Find mid-point between two rectangles, intersection + edge aware -

-

as seen in image, find mid-point between 2 rectangles. if rectangles intersecting mid-point between centers of rectangles. if rectangles not intersecting, mid-point from/between edges of rectangles.

i write in obj-c or swift.

thx

enter image description here

in situation should check first check wether there rectangles overlapped or not.

to check wether overlapped or not

cgrect recta = cgrectmake(50, 50, 50, 50);

cgrect rectb = cgrectmake(100, 100, 50, 50);

if (cgrectgetminx(recta) < cgrectgetmaxx(rectb)  &&  cgrectgetmaxx(recta) > cgrectgetminx(rectb)  &&     cgrectgetminy(recta) < cgrectgetmaxy(rectb)  &&  cgrectgetmaxy(recta) > cgrectgetminy(rectb) ) {     nslog(@"overlapped");  } else {     nslog(@"not overlapped"); }

after finding overlapped or not find centres of both rectangles , whatever want.

to find center.

cgpoint  centerb = cgpointmake((cgrectgetminx(rectb) + cgrectgetmaxx(rectb))/2, (cgrectgetminy(rectb) + cgrectgetmaxy(rectb))/2);

cgpoint centera = cgpointmake((cgrectgetminx(recta) + cgrectgetmaxx(recta))/2, (cgrectgetminy(recta) + cgrectgetmaxy(recta))/2);

mysql - FireDac error 314 - but DLLs are in program directory -

-
i getting when trying access mysql database : [firedac][phys][mysql]-314. cannot load vendor library [libmysql.dll or libmysqlld.dll] this did not happen (unchanged) code, however, have upgraded windows 10 , had reinstall delphi xe8, system configuration matter. in order try solve problem, copied both of files c:\windows\sysytem32. when did not seem work, copied them \win32\debug, generated .exe resides. i imagine doing rather stupid, can't see what. the proper solution place driver file (eg., libmysql.dll ) in application's folder, or place installation location in fddrivers.ini file: [mysql] vendor=<folder>\libmysql.dll (recent versions of documentation seem use vendorlib instead of vendor in ini file.) see rad studio documentation topics configuring drivers (firedac) , connect mysql server (firedac) more information.

-
so per documentation https://developer.github.com/v3/repos/releases/#list-releases-for-a-repository get /repos/:owner/:repo/releases should list relases , https://api.github.com/repos/jquery/jquery/releases should list releases in jquery project , not , why ? because repository doesn't have releases. has tags github presenting in releases page. for more clear example, see: https://github.com/hashicorp/terraform/releases which has both releases , tags showing on page, api shows releases: https://api.github.com/repos/hashicorp/terraform/releases
