ios - Auto layout issue with dynamically loaded XIB -


i have issue auto layout , particular ui flow trying build.

essentially, have following:

  • a storyboard
  • a xib called updateyou.xib
  • a xib called updatefilter.xib

within storyboard scene uiviewcontroller called updateviewcontroller in turn has uisegmentedcontrol 2 options , scrollview.

the general premise when uisegmentedcontrol in option1 loads updateyou.xib in scrollview. constrained width of parent view , expanded vertically required.

however, when option2 of uisegmentedcontrol selected updatefilter xib loaded not constrained width of parent view.

below print out of constraints (the first *** separated log correctly laid out view):

i can see issue additional constraints included in second view know not why there or how have got there. have checked constraints in ib , not included.

i have tried set translatesautoresizingmaskintoconstraints no on offending view makes layout worse!

the xibs added through following code:

- (ibaction)onsegmentedcontrolvaluechanged:(id)sender {     switch (self.segmentedcontrol.selectedsegmentindex) {     case 0:         if (!updateprofileyou) {             updateprofileyou = [[[nsbundle mainbundle] loadnibnamed:@"updateprofileyou" owner:self options:nil] lastobject];         }         [self.scrollview.subviews[0] removefromsuperview];         [self.scrollview addsubview:updateprofileyou];         [self.scrollview setcontentsize:cgsizemake(320, updateprofileyou.frame.size.height)];         break;     case 1:         if (!updateprofilefilters) {             updateprofilefilters = [[[nsbundle mainbundle] loadnibnamed:@"updateprofilefilters" owner:self options:nil] lastobject];         }         [self.scrollview.subviews[0] removefromsuperview];         [self.scrollview addsubview:updateprofilefilters];         [self.scrollview setcontentsize:cgsizemake(320, updateprofilefilters.frame.size.height)];         break;     default:         break;     } }

thanks

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
