iphone - How can I set maskToBounds effect on CAShapeLayer(Rounded-Recr cornered UIView)? -


i want make glow effect spread outside of thisview.

i used code make half-rounded rect cornered uivew.

round 2 corners in uiview

here code. 

+ (uiview *)makeupperhalfroundedview:(uiview *)view {     cashapelayer *masklayer = [cashapelayer layer];     masklayer.frame = view.bounds;     uibezierpath *roundedpath =     [uibezierpath bezierpathwithroundedrect:masklayer.bounds                           byroundingcorners:uirectcornertopleft | uirectcornertopright                                 cornerradii:cgsizemake(8.f, 8.f)];     masklayer.fillcolor = [[uicolor blackcolor] cgcolor];     masklayer.backgroundcolor = [[uicolor clearcolor] cgcolor];     masklayer.path = [roundedpath cgpath]; //    masklayer.maskstobounds = no;      //don't add masks layers in hierarchy!     uiview *superview = [view superview];     [view removefromsuperview];     view.layer.mask = masklayer;     [superview addsubview:view];      return view; }

and there two image buttons in view closed boundary. if touch event happen on buttons, glow effect shows(showstouchwhenhighlighted)

before using piece of code, used

thisview.layer.cornerradius = 8; thisview.layer.maskstobounds = no;

and glow effect spread outside of 'thisview'.

but after using cashapelayer in 'thisview' masking half-roused rect, glow effect masked boundary.

what you're seeing how mask supposed work. applying mask layer of superview. let's call view superview (just in code). okay, do? mask superview , sublayers. that includes subviews. subviews sublayers.

so, since buttons subviews of superview, masked else inside superview.

if don't want happen, don't make buttons subviews of superview. can sit on top of superview without being subviews, example.

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
