iphone - how to disable UIMenuControll (cut,copy,paste,select all,delete) in UIviewController subclass? -


i have implemented many methods paste doesn't hide. using xcode version 4.5.2

-(bool)canperformaction:(sel)action withsender:(id)sender {     uimenucontroller *menucontroller = [uimenucontroller sharedmenucontroller];     if (menucontroller) {         [uimenucontroller sharedmenucontroller].menuvisible = no;      }     return no;   }

every method seems fail working me. can me on this? in advance

you need these things enable/disable uimenucontroller items.

  1. to show/hide uimenucontroller items, view or view controller needs implement canbecomefirstresponder(returning yes/no show/hide).

  2. you can implement canperformaction:withsender: method of uiresponder disable or enable user-interface commands {copy, select, select all, paste , etc} based on context.

  3. or can override update method of uimenucontroller handle custom behavior of individual item. example, if pasteboard holds no data of compatible type, paste command disabled. may either force show/hide paste menu item overriding method.

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...
