i'm trying reach controller looks similar this: notice customize size of capture screen, , white border around it. know, it's impossible change background color of uiimagepickerviewcontroller, im trying implement overlayview go above it. the main issue need make mask view show camera in middle of overlay view, , far came short. any ideas on how implement this? how can make mask view cuts "hole" in overlay view see camera underneath it? thanks! i suggest creating custom camera. let put sorts of overlays etc. check out avcapturesession there bunch of tutorials online describing how easily. first result google search: https://dannygtech.wordpress.com/2014/03/04/custom-camera-on-ios-avcapturesession-avcapturevideopreviewlayer-tutorial/

is there function in apache derby can convert unix epoch time value (eg. 1453974057 ) date? if have seconds since unix epoch, use: select {fn timestampadd(sql_tsi_second, 1453974057, timestamp('1970-01-01-00.00.00.000000')) } dt sysibm.sysdummy1 just replace "sysibm.sysdummy1" original table, , replace 1453974057 value. when dealing milliseconds gets bit more complicated because can't use timestampadd directly (you sql state 22003: resulting value outside range data type integer.) if have milliseconds since unix epoch, use: select --the following block converts milliseconds since linux epoch timestamp { fn timestampadd( sql_tsi_frac_second, ( --add millisecond component 1453974057235 - { fn timestampdiff( sql_tsi_second, timestamp('1970-01-01-00.00.00.000000'), { fn timestampadd(sql_tsi_second, 1453974057235/1000, timestamp('1970

i'm using jersey 2.22 consume rest api. approach contract-first, service interface , wrappers used call rest api (using org.glassfish.jersey.client.proxy package). webclient webclient = clientbuilder.newclient(); webtarget webtarget = webclient.getwebtarget(endpoint); serviceclass proxy = webresourcefactory.newresource(serviceclass.class, webtarget); object returnedobject = proxy.servicemethod("id1"); the question is: how underlying http response (http status + body)? when returnedobject null, need analyze response error message returned example. there way it? saw can plug filters , interceptors catch response, that's not need. you should return response result of interface method instead of plain dto. i'm not sure level of control you're expecting (considering reply @peeskillet comment), response object give opportunity fine tune server's response (headers, cookies, status etc.) , read of them @ client side - might see t
