iphone实现NavigationController 导航栏中的系统按钮

实现右边的书签按钮：

 1 UIBarButtonItem *anotherButton = [[UIBarButtonItem alloc] 
 2 
 3 initWithBarButtonSystemItem:UIBarButtonSystemItemBookmarks target:self 
 4 
 5 action:@selector(methodtocall:) ]; 
 6 
 7 self.navigationItem.rightBarButtonItem = anotherButton; [anotherButton release]; 
 8 
 9 //由于本地视图会retain它，所以我们可以release了。
10
