IOS改变导航栏标题颜色

//直接用系统的

//设置导航栏的标题    self.navigationItem.title=@"选择奖励对象";    //设置字体大小和颜色    [self.navigationController.navigationBar setTitleTextAttributes:  @{NSFontAttributeName:[UIFont systemFontOfSize:18],    NSForegroundColorAttributeName:[UIColor whiteColor]}];

自己定制的

//自定义标题视图UILabel *titleLabel = [[UILabel alloc] initWithFrame:CGRectMake(0, 0, 200, 44)];titleLabel.backgroundColor = [UIColor grayColor];titleLabel.font = [UIFont boldSystemFontOfSize:20];titleLabel.textColor = [UIColor greenColor];titleLabel.textAlignment = NSTextAlignmentCenter;titleLabel.text = @"标题";self.navigationItem.titleView = titleLabel;
