將uiswich添加爲導航項

Question

以哪種方式，我可以通過編程方式將uiswitch添加爲導航項或btw在我的導航欄上？ 我要瘋了：d

Answer 1

self.navigationItem.rightBarButtonItem = [[[UIBarButtonItem alloc] initWithCustomView: mySwitch] autorelease]; 

Answer 2

UISwitch *foo = [[UISwitch alloc] init]; 
UIBarButtonItem *item = [[UIBarButtonItem alloc] initWithCustomView:foo]; 
self.navigationItem.rightBarButtonItem = item; 
[item release]; 
[foo release];
