ios - Cannot animate CALayer strokeColor -


i've been trying draw simple rectangle , animate edge color. tried using following link , still doesn't help. fixed changing layer's border color , animating same. worked fine.

is there kvo strokecolor because i'm getting working backgroundcolor of layer.

i'm on xcode 4.6 running ios sdk 6.1

this i've been doing:

cgcontextref context = uigraphicsgetcurrentcontext(); cgcontextsetlinewidth(context, 2.0); cgcontextsetstrokecolorwithcolor(context, [uicolor bluecolor].cgcolor);  cabasicanimation *strokeanim = [cabasicanimation animationwithkeypath:@"strokecolor"]; strokeanim.fromvalue         = (id) [uicolor redcolor].cgcolor; strokeanim.tovalue           = (id) [uicolor greencolor].cgcolor; strokeanim.duration          = 3.0; strokeanim.repeatcount       = 0; strokeanim.autoreverses      = yes; [self.layer addanimation:strokeanim forkey:@"animatestrokecolor"];  cgcontextmovetopoint(context, 0, 0); cgcontextaddlinetopoint(context, squarelength, 0); cgcontextaddlinetopoint(context, squarelength, squarelength); cgcontextaddlinetopoint(context, 0, squarelength); cgcontextaddlinetopoint(context, 0, 0); cgcontextstrokepath(context);

tl;dr; meant @"bordercolor"

unless did override + (class)layerclass in view (which doubt did) view's layer going calayer instance doesn't have strokecolor property.

you use cashapelayer shouldn't stroke since calayer has bordercolor property looking for.

so advice animate bordercolor instead.

not related question:

from code you've posted looks adding animation inside of views drawrect: implementation. method should used actual drawing , suggest move animation code somewhere else. method called every time view redraws , adding new animation.

Why does Ruby on Rails generate add a blank line to the end of a file? -

running rails generate controller foo home results in: class foocontroller < application controller def home end end (there's nothing on line in actual file, blank line) is there purpose blank line? it's common use newline indicate end of line, last line. many editors (like vi, use) add in newline silently. consensus text files (especially in unix world) should end in newline, , there have been problems historically if wasn't present. why should text files end newline? the tool used count lines in file "wc" counts newlines in file, without trailing newline show 3 instead of 4. it improves readability of templates used in generator. consider: https://github.com/rails/rails/blob/master/railties/lib/rails/generators/rails/controller/templates/controller.rb to remove trailing newline, template have last line of: end<% end -%> instead of: end <% end -%> that seems less readable me. the discussion below refers ...
