導航欄設置多個按鈕、背景圖、圖片與文字按鈕方法小結

設置一個按鈕的方法就不再贅述了

1. 設置多個按鈕

法一：

    UIBarButtonItem *oneButton = [[UIBarButtonItemalloc]initWithTitle:@"設置" style:UIBarButtonItemStylePlain

target:selfaction:@selector(oneButtonAction:)];

    UIBarButtonItem *twoButton = [[UIBarButtonItemalloc]initWithTitle:@"消息" style:UIBarButtonItemStyleDone target:selfaction:@selector(twoButtonAction:)];

    NSArray *actionButtonItems = @[oneButton,   twoButton];

    self.navigationItem.rightBarButtonItems = actionButtonItems;

注：以上的style參數，我寫的是UIBarButtonItemStylePlain和UIBarButtonItemStyleDone兩種方式，UIBarButtonItemStyleDone默認字體為系統按鈕的字體的設置（加粗），UIBarButtonItemStylePlain默認字體為lable的字體設置（17號字，無加粗）

 

法二：（此法本人不推薦，因為在點擊時，兩個按鈕的背景（即UIToolbar的背景）都會有常亮顯示）

    UIToolbar* tools = [[UIToolbar alloc] initWithFrame:CGRectMake(0, 0, WIDTHINIPHONE6(95), 44)];

    [tools setBarTintColor:DOMINANTCOLOR];

    [tools setTintColor:WHITEBACK];

    [tools setAlpha:[self.navigationController.navigationBar alpha]];

    UIBarButtonItem *setBtn = [[UIBarButtonItem alloc] initWithTitle:@"設置" style:UIBarButtonItemStylePlain target:self action:@selector(setUserSetting)];

    UIBarButtonItem *msgBtn = [[UIBarButtonItem alloc] initWithTitle:@"消息" style:UIBarButtonItemStylePlain target:self action:@selector(lookUserMsg)];

    NSArray *btnArr = @[setBtn,msgBtn];

    [tools setItems:btnArr];

    UIBarButtonItem *right = [[UIBarButtonItem alloc] initWithCustomView:tools];

 

      2.  背景圖

 [navigationController.navigationBar setBackgroundImage:[UIImage imageNamed:@""] forBarMetrics:UIBarMetricsDefault];

      3.  圖片與文字按鈕（這里我以自定義左部按鈕為例）

    _leftBtn = [UIButton buttonWithType:UIButtonTypeCustom];
    _leftBtn.frame = CGRectMake(0, 0, 60, 25);
    [_leftBtn setTitle:@"返回" forState:UIControlStateNormal];
    [_leftBtn setImage:[UIImage imageNamed:@"back"] forState:UIControlStateNormal];
    _leftBtn.titleLabel.font = HEADFONT;
    [_leftBtn addTarget:self action:@selector(goback) forControlEvents:UIControlEventTouchUpInside];
    _leftBtn.imageEdgeInsets = UIEdgeInsetsMake(0, -10, 0, 0);
    _leftBtn.titleEdgeInsets = UIEdgeInsetsMake(0, -20, 0, 0);
    UIBarButtonItem *leftButton = [[UIBarButtonItem alloc] initWithCustomView:_leftBtn];

    self.navigationItem.leftBarButtonItem = leftButton;
