iphone - resize toolbar in UINavigationController -

-

i'm adding series of buttons uinavigationbar using:

    nsarray *items;          items = [nsarray arraywithobjects:                  fixedspace,                  refreshstopbarbuttonitem,                  flexiblespace,                  self.backbarbuttonitem,                  flexiblespace,                  self.forwardbarbuttonitem,                  flexiblespace,                  self.actionbarbuttonitem,                  fixedspace,                  nil];      uitoolbar *toolbar = [[uitoolbar alloc] initwithframe:cgrectmake(0.0f, 0.0f, toolbarwidth, 44.0f)];      toolbar.items = items;      toolbar.tintcolor = [[uicolor whitecolor] colorwithalphacomponent:1.0];      toolbar.autoresizingmask = uiviewautoresizingflexibleheight;      self.navigationitem.rightbarbuttonitem = [[uibarbuttonitem alloc] initwithcustomview:toolbar];

all working well.

however when rotate landscape mode toolbar within uinavigationbar doesn't rotate.

adding code (found on so) causes toolbar resize not buttons within it, partially cropped @ bottom , no longer lines toolbar background

- (void)willanimaterotationtointerfaceorientation:(uiinterfaceorientation)tointerfaceorientation duration:(nstimeinterval)duration {     cgrect navigationtoolbarframe = self.navigationcontroller.navigationbar.frame;     cgrect customtoolbarframe = cgrectoffset(navigationtoolbarframe, 0.0, navigationtoolbarframe.size.height);     [uiview animatewithduration:duration animations:^{         //self.toolbar.frame = customtoolbarframe;         // fails!!!         //self.navigationitem.rightbarbuttonitem.toolbar.frame = customtoolbarframe;         // fails!!!     }]; }

what correct way address toolbar within uinavigationbar? like...

self.toolbar.frame = customtoolbarframe;

or have specify autoresizemask uibarbuttonitems?...

self.backbarbuttonitem.autoresizingmask = uiviewautoresizingflexibleheight;

... trying fails

  1. very curious because code rotates toolbar fine when include in code. no problem rotating toolbar.

  2. i assume view controller responding shouldautorotatetointerfaceorientation? include screen snapshot of you're seeing?

  3. are doing uitoolbar category/subclass eliminate border? (i subclass empty (void)drawrect:(cgrect)rect rid of border, tried both , standard uitoolbar , both rotated fine.) anyway, if you're doing subclass/category of uitoolbar, please include code?

  4. also, alternatively use ios 5's rightbarbuttonitems , bypass toolbar altogether, e.g. self.navigationitem.rightbarbuttonitems = items; add array of uibarbuttonitem objects navigation bar.

  5. this bit of long shot, how view controller being loaded? people try bypassing presentviewcontrolleranimated and/or pushviewcontroller , instead create view controller, grab view, add subview of previous view controller's view. unfortunately, ends disconnect between view controller hierarchy , view hierarchy, , according wwdc 2011 session 102 on view controller containment, can prevent rotation events being transmitted correctly. make sure you're using presentviewcontrolleranimated or pushviewcontroller if isn't root view controller.

i don't of willanimaterotationtointerfaceorientation or subsequent code, simple uitoolbar , works fine during rotation, wonder if problem rests elsewhere.

All overlapping substrings matching a java regex -

-
is there api method returns (possibly overlapping) substrings match regular expression? for example, have text string: string t = 04/31 412-555-1235; , , have pattern: pattern p = new pattern("\\d\\d+"); matches strings of 2 or more characters. the matches are: 04, 31, 412, 555, 1235. how overlapping matches? i want code return: 04, 31, 41, 412, 12, 55, 555, 55, 12, 123, 1235, 23, 235, 35. theoretically should possible -- there obvious o(n^2) algorithm enumerates , checks substrings against pattern. edit rather enumerating substrings, safer use region(int start, int end) method in matcher . checking pattern against separate, extracted substring might change result of match (e.g. if there non-capturing group or word boundary check @ start/end of pattern). edit 2 actually, it's unclear whether region() expect zero-width matches. specification vague, , experiments yield disappointing results. for example: string line = "xx90xx"; strin...
