ios - clip-masking uiview with CAShapeLayer and UIBezierPath -


i have problem clipping view using cashapelayer-uibezierpath , want clip content end getting stroke (frame) uibezierpath , code 

uibezierpath *path2path = [uibezierpath bezierpath]; [path2path movetopoint:cgpointmake(206.745, 0)]; [path2path addlinetopoint:cgpointmake(206.745, 97.613)]; [path2path addlinetopoint:cgpointmake(0, 97.613)]; [path2path addlinetopoint:cgpointmake(0, 0)]; [path2path addlinetopoint:cgpointmake(87.28, 0)]; [path2path addcurvetopoint:cgpointmake(103.808, 12.118) controlpoint1:cgpointmake(87.28, 0) controlpoint2:cgpointmake(86.555, 12.118)]; [path2path addcurvetopoint:cgpointmake(119.466, 0) controlpoint1:cgpointmake(121.061, 12.118) controlpoint2:cgpointmake(119.466, 0)]; [path2path addlinetopoint:cgpointmake(206.745, 0)]; [path2path closepath];  [path2path addclip];  cashapelayer *pathlayer = [cashapelayer layer]; pathlayer.frame=myview.bounds; pathlayer.path = path2path.cgpath;  pathlayer.strokecolor = [[uicolor blackcolor] cgcolor]; pathlayer.fillcolor = [[uicolor clearcolor] cgcolor];  pathlayer.fillrule=kcafillruleevenodd; [myview.layer setmask:pathlayer]; [myview.layer setmaskstobounds:yes];  myview.backgroundcolor=[uicolor greencolor];

the result of code green stroke line ,the bounds empty , http://i.stack.imgur.com/aehdo.png

however , want make bounds green , clipped stroke

as rob mayoff said you can setting view's layer mask cashapelayer.

uibezierpath *myclippingpath = ... cashapelayer *mask           = [cashapelayer layer]; mask.path                    = myclippingpath.cgpath; myview.layer.mask            = mask;

in swift

let myclippingpath = uibezierpath( ... ) let mask           = cashapelayer() mask.path          = myclippingpath.cgpath layer.mask         = mask

powershell Start-Process exit code -1073741502 when used with Credential from a windows service environment -

i'm running strange behavior powershell start-process call. here call: $process = start-process ` "c:\somepath\mybinary.exe" ` -passthru ` -credential $defaultcredential ` -wait ` -workingdirectory "c:\somepath" ` -loaduserprofile if ($process.exitcode -ne 0) { #do } this call return exit code - 1073741502 . after quick search, exit code seems related generic error when program not load required dll (aka. status_dll_init_failed ). when run without -credential $credential program runs correctly. in order isolate problem, manually launched some.exe in prompt target credential , runs smoothly. so problem seems come way start-process cmdlet launch process. i found potential solutions problem tried apply no luck : link , link . would have idea of what's going on here ? edit 1: run proc mon monitoring program activities when launched directly or via powershell script. problem seems occur when loading kernelbase
