导航栏设置多个按钮、背景图、图片与文字按钮方法小结

设置一个按钮的方法就不再赘述了

设置多个按钮

法一：

UIBarButtonItem *oneButton = [[UIBarButtonItemalloc]initWithTitle:@"设置" 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参数，我写的是UIBarButtonItemStylePlain和UIBarButtonItemStyleDone两种方式，UIBarButtonItemStyleDone默认字体为系统按钮的字体的设置（加粗），UIBarButtonItemStylePlain默认字体为lable的字体设置（17号字，无加粗）

法二：（此法本人不推荐，因为在点击时，两个按钮的背景（即UIToolbar的背景）都会有常亮显示）

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:@"设置" 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. 背景图

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

3. 图片与文字按钮（这里我以自定义左部按钮为例）

    _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;
