ios - How do I link my UIButton to a line of code inside my didFinishLaunching? -


i want button restart view when clicked, when click on want run following line of code: 

[self.navigationcontroller pushviewcontroller:self.viewcontroller animated:yes];

or want run entire didfinishlaunching method?

how link button ?

any appreciated!

i don't know mean

reload app when clicked

but doing on buttonclick have create action button 

 [mybutton addtarget:self action:@selector(buttonclicked:) forcontrolevents:uicontroleventtouchupinside];  -(void)buttonclicked { [self.navigationcontroller pushviewcontroller:self.viewcontroller animated:yes]; }

and explicitly calling didfinishlaunching not right , recommended way it.

you can make method contains didfinishlaunching code , call method on buttonclick

to access appdelegate method viewcontroller use

-(void)buttonclicked {    appdelegate *appdelegate = (appdelegate *)[[uiapplication sharedapplication] delegate];    [appdelegate methodtocall]; }

linux - xterm copying to CLIPBOARD using copy-selection causes automatic updating of CLIPBOARD upon mouse selection -

i've tried various ways coerce xterm (versions 285 , 292) copy selection clipboard clipboard whenever press ctrl-shift-c. promising way far has been, in ~/.xresources, put this: xterm*vt100.translations: #override \ ctrl shift <keypress> c: copy-selection(clipboard) \n\ ctrl shift <keypress> v: insert-selection(clipboard) ctrl-shift-v works perfectly, copying has nuance... if restart xterm, highlighting text puts things in primary clipboard; expected, proper, default behavior. if hit ctrl-shift-c, copies current selection clipboard clipboard. the bug, however, if highlight text after first time pressed ctrl-shift-c, you'll see highlighting copies both primary and clipboard. cannot figure out how stop xterm updating clipboard upon selection... , doesn't make sense me in first place. i said, @ specific point in time, copy selection clipboard... yet starts updating automatically upon selection after doing once... anyone have workaround...
