1.隐藏/去掉 导航栏返回按钮中的文字
[[UIBarButtonItem appearance] setBackButtonTitlePositionAdjustment:UIOffsetMake(0, -60)
forBarMetrics:UIBarMetricsDefault];
2.设置statusBar颜色为白色
效果图
self.navigationController.navigationBar.barStyle = UIBarStyleBlack;
[[UIApplication sharedApplication]setStatusBarStyle:UIStatusBarStyleLightContent];
如果该方法没有用可：
- (UIStatusBarStyle)preferredStatusBarStyle {
return UIStatusBarStyleLightContent;
}
3.给navigationBar上添加多个按钮
图例
下面贴一个leftItem的例子
- (void)addLeftItem {
UIView *leftBarView = [[UIView alloc]initWithFrame:CGRectMake(0, 0, 80, 31)];
UIButton *phonebutton = [UIButton buttonWithType:UIButtonTypeCustom];
phonebutton.frame=CGRectMake(0, 5, 25, 25);
[phonebutton setImage:[UIImage imageNamed:@"w_qianbao_kefu"] forState:UIControlStateNormal];
UILabel *leftLabel = [[UILabel alloc]initWithFrame:CGRectMake(30, 5, 40, 20)];
leftLabel.text = @"客服";
leftLabel.textColor = [UIColor whiteColor];
leftLabel.font = [UIFont systemFontOfSize:15.0f];
leftLabel.backgroundColor = [UIColor clearColor];
[leftBarView addSubview:leftLabel];
[leftBarView addSubview:phonebutton];
leftBarView.backgroundColor=[UIColor clearColor];
UIBarButtonItem *leftItem = [[UIBarButtonItem alloc]initWithCustomView:leftBarView];
self.navigationItem.leftBarButtonItem = leftItem;
}
原理:在item上添加一个view，然后再在view上添加按钮
4.给导航栏设置一张背景图
[self.navigationController.navigationBar setBackgroundImage:[UIImage imageNamed:@"navigationBar_back"] forBarPosition:UIBarPositionAny
barMetrics:UIBarMetricsDefault];
去掉导航栏下方的线
[self.navigationController.navigationBar setShadowImage:[UIImage new]];
