i've been trying understand auto layout, keep failing , need help. in test project below wanted align 4 squares in both portrait , landscape modes on devices. need know constraints doing wrong. i used views in case. in first step added equal width/size pins since squares same size. size of squares w:250 h:121. view container inferred option in second step added width , height pins (cushions) between squares. in third step added necessary outside constraints individual squares superview (leading,trailing,top top layout, bottom bottom layout). and constraints end doing; fine in portrait weird/don't show in landscape. what doing wrong? a size class issue, constraint issue, missing steps, or else? in 3.5 , 4 inch doesnt show because fixed constraint bottom of superview, constraint's constant value alone higher screen itself, forcing views's height become 0 (or small on bigger 5.5 screen in screenshot), fixing this, try use less consta...

i using tableview 2 rows. each row having label, button , image view .initially the row height 50 no image. when click button in cell image picker open , select image camera roll. how can update tableview height 100 image view in cell? you can achieve using autolayout. if design cell in xib : cell height 100 : with these constraints on image view : it height 50 : the weird line image view got automatically shrunk autolayout. looks bad in interface builder, ok on device/simulator. 1 thing have remember remove image (not image view!) when cell @ 50 height , set when @ 100. also i'd recommend learn autolayout powerful tool.

i run following function controller, using interval , producing 3 different avatars in view template. at moment, produces 1 avatar.png , love produce 3 different. so how can set html displays 3 different images? here code: controller: $scope.capture = function(){ var canvas = document.getelementbyid('canvas'); var video = document.getelementbyid('video'); canvas.getcontext('2d').drawimage(video, 0, 0, video.videowidth, video.videoheight); } $interval (function(){ $scope.capture(); }, 1500); and template canvas image drawn: <canvas id="canvas"></canvas> so basically, want after 1.5 seconds image drawn , total images drawn should 3. each image it's own canvas id different. why don't use $timeout for(var i=0;i<3;i++) { $timeout (function(){ $scope.capture(); }, 1500*i); } this execute function 3 times. may need write logic draw image in different canvas different ids. ...

i want when 1 of evalerror, rangeerror, referenceerror, syntaxerror, typeerror, urierror thrown through code want these error should thrown after ajex request can know analyse client error logs. when went deep, found sevral interface created these error extending error class e.g. interface typeerror extends error { } interface typeerrorconstructor { new (message?: string): typeerror; (message?: string): typeerror; prototype: typeerror; } declare var typeerror: typeerrorconstructor; interface error { name: string; message: string; } interface errorconstructor { new (message?: string): error; (message?: string): error; prototype: error; } declare var error: errorconstructor; so there way redefine/update these interface defination before throwing these error should make ajex request server. note: i dont want use windows.onerror since other library(rollbar) has own onerror implimentation. is possible redefine these interface. e.g. c...

if have replacing entirety of slice of state, still have use object.assign or spread operator make copy of original state , replace new state, or can return new state in reducer? const fetching = (state = { isfetching: false }, action) => { switch (action.type) { case 'requesting': return object.assign({}, state, { isfetching: true } ) case 'receive_pokemon_type_info': return object.assign({}, state, { isfetching: false } ) default: return state } } vs. const fetching = (state = { isfetching: false }, action) => { switch (action.type) { case 'requesting': return { isfetching: true } case 'receive_pokemon_type_info': return { isfetching: false } default: return state } } there couple of things going on here. basically, if state only consists of boolean variable, creating new object enumeration ok. however, if state consists of other things, doing object.assign sh...

i have separated quite small jenkins jobs. now need configure job depending on selected user parameters (selected through checkboxes?) execute of them. i start them powershell or bash or groovy script. possible? if using groovy in postbuild/pipeline step, can start job via jenkins api. for example, parameterless builds: import hudson.model.* jenkins.instance.getitem("my job").schedulebuild(5) and parameterized builds: import hudson.model.* jenkins.instance.getitem("my job").schedulebuild( 5, new cause.upstreamcause( currentbuild ), new parametersaction([ new stringparametervalue( "my parameter name", "my parameter value" ) ])); you can use jenkins rest api rest. example, hitting following url: parameterless: curl -x post jenkins_url/job/job_name/build parameterized: curl -x post jenkins_url/job/job_name/buildwithparameters?myparametername=myparametervalue
