iphone - modalViewController delegate callbacks - HowTo? -

i have view controller, , when click button create modalview (wrapped uinavigationcontroller) , nowadays it.

dscviewcontroller *enterdescription = [[[dscviewcontroller alloc] init] autorelease]; uinavigationcontroller* navcontroller = [[uinavigationcontroller alloc] initwithrootviewcontroller:enterdescription]; [self presentmodalviewcontroller:navcontroller animated:yes]; [navcontroller release];

the question is, how create (parent)view controller delegate, , when click on button @ modalviewcontroller (done example) phone call method in parent viewcontroller dismiss modal , savings modal input?

i don't think it's practice create 1 controller blame parent controller work should handel. can utilize self.parentviewcontroller dismiss modal in.

if reason handle storage in parentviewcontroller can point done button action method in current viewcontroller , utilize self.parentviewcontroller trigger parent method storage.

or set buttons delegate straight self.parentviewcontroller

[button addtarget:self.parentviewcontroller action:@selector(somemethodinparentviewcontroller) forcontrolevents:uicontroleventtouchupinside];

string - what is the difference between "some" == "some\0" and strcmp("some","some\0") in c++? -

string - what is the difference between "some" == "some\0" and strcmp("some","some\0") in c++? - what difference between "some" == "some\0" , strcmp("some","some\0") in c++? why if("some" == "some\0") returns false , if(!strcmp("some","some\0")) returns true ? see next diagram. shows 2 strings in memory, content in box, beside box you'll see address of each one. when you're doing if("some" == "some\0") comparing addresses. translated if (0xdeadbeef == 0x0badcafe) false. when utilize strcmp , compare content of each box until reach \0 in each of them. that's why sec test returns true. if alter first test if("some" == "some") compiler may potentially see same strings , store them once. means test transform if (0x0badcafe == 0x0badcafe) true. c++ string comparison

actionscript 3 - Flex: moving a point with rotation doesnt change the point XY? - i have follow issue : i have point setted @ border on component, changed transform point center of component in order match component rotation. the of import part when seek point xy after rotation - remains same before rotation. how xy, after rotation ( changeing point.rotation property specific degrees of rotaion ) if want point after rotation, cos(r) * x, sin(r) * y easiest way. if want point after transformations, should able utilize displayobject.transform.transformpoint(x, y) . there's displayobject.localtoglobal . in case phone call localtoglobal(x, y) , localtoglobal(0, 0) , calculate difference. see transform livedocs , displayobject livedocs flex actionscript-3
