IOS開發：導覽列添加多個按鈕以及在左邊添加logo

標籤：style   blog   io   os   ar   on   2014   log   cti   

添加多個按鈕，同樣可以只添加一個

 UIBarButtonItem *anotherButton = [[UIBarButtonItem alloc] initWithTitle:NSLocalizedString(@"register", nil) style:UIBarButtonItemStylePlain target:self action:@selector(registerClick:)];            UIBarButtonItem *anotherButton2 = [[UIBarButtonItem alloc] initWithTitle:NSLocalizedString(@"login", nil) style:UIBarButtonItemStylePlain target:self action:@selector(loginClick:)];            [self.navigationItem setRightBarButtonItems:[NSArray arrayWithObjects: anotherButton,anotherButton2,nil]];

添加Logo,只在第一個頁面顯示，用下面這個方法

self.shareNavleftView = [[UIView alloc] init];        self.shareNavleftView.frame = CGRectMake(0.0, 0.0, 191.0, 47.0);        UIImageView *img = [[UIImageView alloc] init];        img.image = [UIImage imageNamed:@"oatosLogo.png"];        img.autoresizingMask = UIViewAutoresizingFlexibleWidth;        img.frame = self.shareNavleftView.frame;        [self.shareNavleftView addSubview:img];        self.navigationItem.leftBarButtonItem = [[UIBarButtonItem alloc] initWithCustomView:self.shareNavleftView];

用下面這個方法，則會把Logo添加到後面的每一個頁面，不符合我的需求

[self.navigationController.view addSubview:self.shareNavleftView];
