ios - UITextView drawing text twice -


i'm trying create stroked text on uitextviews text. it's working fine, text drawing twice on screen. here drawrect method in subclass of uitextview...

- (void)drawrect:(cgrect)rect {     // drawing code     // drawing code      uifont *font = [uifont fontwithname:@"cochin" size:[_fontsize floatvalue]];      cgcontextref context = uigraphicsgetcurrentcontext();     cgcontextsetshadow(context, cgsizemake(1, 1), 1);     cgcontextsetrgbfillcolor(context,1,1,1, 1);     cgcontextsetrgbstrokecolor(context, 0, 0, 0, 1);     cgcontextsetlinewidth(context, .35);     cgcontextsettextdrawingmode(context, kcgtextfillstroke);     cgcontextsavegstate(context);     [[self text] drawinrect:rect withfont:font]; }

i tried setting clearscontextondraw yes, didn't trick. please...

i've tried code , work me. there couple of notes though:

  1. you should use self.bounds target rect draw to, not rect parameter get, since means 'this invalid area of view'. performance optimization , need use it.

  2. you don't need call cgcontextsavegstate (and when do, want restore after that). when call subroutine modifies current context (and restore afterwards), ideally, should moved routine itself.

try setting background of view white , make font bigger, might hints of what's going on. also, post screenshot here.

update:

i haven't noticed using uitextview. should not use class , custom drawing! if wanna draw text yourself, subclass uiview. if wanna use uitextview, use attributedstring property of uitextview (set in viewdidload example, in uiviewcontroller subclass. here's more info on attributed strings: apple docs

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 ...
