hello i'm trying make simple countdown app. however countdown in seconds , not in minutes , hours. how make such? create timer: timer = [nstimer scheduledtimerwithtimeinterval: 1.0 target:self selector:@selector(countdown) userinfo:nil repeats: yes]; countdown method: -(void) countdown { int hours, minutes, seconds; secondsleft--; hours = secondsleft / 3600; minutes = (secondsleft % 3600) / 60; seconds = (secondsleft %3600) % 60; label.text = [nsstring stringwithformat:@"%02d:%02d:%02d", hours, minutes, seconds]; } reference : https://developer.apple.com/library/ios/documentation/cocoa/conceptual/timers/articles/usingtimers.html

in grails there 2 ways m:m associations. firstly, have collection on both sides. gorm figure out intermediately table , encapsulated away. the second way have 3 objects, third object representing connecting table. approach means more code means can add columns actual relationship table easily. is there name second approach? i'm not aware of names these different approaches. database point-of-view aren't different approaches, because in both cases have n:n relationship join table (this refer "the intermediately [sic] table"), in 1 case have additional columns (to foreign keys) in join table at gorm level, approaches more different because in 1 case have domain class (mapped join table), again, i'm not aware of specifics names these different approaches.

i want redraw view method (say setprogress) in class extending view. how can this. my view class is public class spinview extends view { private paint paint; private context context; private canvas canvas; private rectf arcoval; public spinview(context context) { super(context); this.context = context; } public spinview(context context, attributeset attrs) { super(context, attrs, 0); this.context = context; } public spinview(context context, attributeset attrs, int defstyle) { super(context, attrs, defstyle); this.context = context; } @override protected void ondraw(canvas canvas) { super.ondraw(canvas); this.canvas = canvas; display d = ((windowmanager)context.getsystemservice(context.window_service)).getdefaultdisplay(); int width = d.getwidth(); int height = d.getheight(); arcoval = new rectf((width/2-50), (height/2-50), (width/...

i have print entire text of text field picture. reason is: have exchange messages unsupported utf-8 characters between android , other web clients. unsupported utf-8 characters mean missing fonts in android (see this topic here ). tried use direct way bitmap b; edittext edittext = (edittext) findviewbyid(r.id.edittext); edittext.builddrawingcache(); b = edittext.getdrawingcache(); edittext.destroydrawingcache(); which works charm until have multiple lines: solution captures text visible user instead of complete text inside of long text field (scrollbars!). i tried workaround generating picture stackoverflow answer . prints entire text not respect text formatting newlines. don't want handle stuff myself. i forced use android 4.3 , earlier versions. is there smart way capture text pictures? if not: is possible modify code above work expected? after searching 24 hours solution ran into solution webview . trick is generate view hold content avoid marker ed...
