iphone - UIPickerView programatic example? -

how programmatically setup uipickerview in view without using interface builder? having problem understanding how work delegate portions of uipickerview.

thanks

it goes follows add together uipickerview programmatically:

- (void)pickerview:(uipickerview *)pv didselectrow:(nsinteger)row incomponent:(nsinteger)component { if(component == 1) selectedrowpicker1 = row; else if(component == 2) selectedrowpicker2 = row; else selectedrowpicker3 = row; } - (nsinteger)numberofcomponentsinpickerview:(uipickerview *)pickerview { homecoming 3; } - (nsinteger)pickerview:(uipickerview *)pickerview numberofrowsincomponent:(nsinteger)component { if(component == 1) homecoming [list1 count]; else if(component == 2) homecoming [list2 count]; else homecoming [list3 count]; } - (nsstring *)pickerview:(uipickerview *)pickerview titleforrow:(nsinteger)row forcomponent:(nsinteger)component { if(component == 1) val1 = [list1 objectatindex:row]; else if(component == 2) val2 = [list2 objectatindex:row]; else val3 = [list3 objectatindex:row]; homecoming strtemp; }

let me know if have questions in uipickerview implementation.

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
