ios导航栏自定义

在viewDidLoad函数里写上

//自定义导航栏颜色

[self.navigationController.navigationBar setBarTintColor:[UIColor colorWithRed:50/255.0 green:147/255.0 blue:209/255.0 alpha:1]];

//自定义导航栏背景图片

[self.navigationController.navigationBar setBackgroundImage:[UIImage imageNamed:@"bg_banner10.png"] forBarMetrics:UIBarMetricsDefault];

//修改导航栏标题字体大小和颜色

[self.navigationController.navigationBar setTitleTextAttributes:@{

NSFontAttributeName:[UIFont systemFontOfSize:19],

NSForegroundColorAttributeName:[UIColor whiteColor]

}];
