layer - iOS - CALayer setShadowColor not working -

-

i need set bottom shadow button. have shadow somehow cannot change shadow color. doing wrong? here code:

[self.buttonsbar.layer setshadowcolor:[uicolor colorwithred:227.0f/255 green:233.0f/255 blue:239.0f/255 alpha:1.0f].cgcolor]; [self.buttonsbar.layer setshadowopacity:1]; [self.buttonsbar.layer setshadowradius:1]; [self.buttonsbar.layer setshadowoffset:cgsizemake(0, 1)];

make sure self.buttonsbar.clipstobounds = no;
make sure self.buttonsbar.layer.maskstobounds = no;
first try large radius , offset make sure see them reduce numbers, not easy see shadow depending on background colors ...

i have implement video collection website users of specific isp. site hosted on public web-server movies hosted on local isp server. user of isp + general visitors can see available movies; isp's users able play them. player on site point url of local machine ( http://192.x.x.x/movies/mymovie.mov ) private class (192.x.x.x) accessible isp user. question: possible phpmotion script? or need custom work. if possible, can please suggest available mods? phpmotion require modifications able handle this. uploading, conversion, thumbnail generation, , playback pretty static in phpmotion. really though, rather modding entire upload , conversion process, if created quick custom form add entries phpmotion database (maybe include thumbnail upload), tweaked playback paths, should go on phpmotion side of things. assume had videos in format player handle (such flv or mp4).
