更改标签栏编辑视图控制器的色调颜色

Question

我想更改标签栏控制器的编辑视图控制器的色调颜色。我已经设法改变了更多视图控制器的颜色，但没有得到这方面的线索。

此代码用于更改用UITabBarController的子标记编写的更多视图控制器的颜色

  override func viewDidLoad() {
    super.viewDidLoad()
    var view = self.moreNavigationController.topViewController.view as UITableView
    view.tintColor = Utilities.mainColor()
    view.separatorStyle = .None
  }

对Objective-C或Swift

的建议表示欢迎

Answer 1

通过尝试以下代码为我工作

  override func viewDidLoad() {
    super.viewDidLoad()
    //this line helped me
    self.view.tintColor = Utilities.mainColor()
  }

Answer 2

您可以为tabBarItem手动设置彩色图像。

UIImage *defaultImage = [UIImage imageNamed:@"sports"];
defaultImage = [defaultImage imageWithRenderingMode:UIImageRenderingModeAlwaysOriginal];//system tints wont apply on the default image
UIImage *selectedImage = [[UIImage imageNamed:@"sports"] imageWithColor:tintColor];
selectedImage = [selectedImage imageWithRenderingMode:UIImageRenderingModeAlwaysOriginal];//System tints wont apply on this image
UITabBarItem *item = [[UITabBarItem alloc] initWithTitle:@"Sports" image:defaultImage selectedImage:selectedImage];
        }

以下功能可用于手动着色图像

- (UIImage *)imageWithColor:(UIColor *)color1
{
    UIGraphicsBeginImageContextWithOptions(self.size, NO, self.scale);
    CGContextRef context = UIGraphicsGetCurrentContext();
    CGContextTranslateCTM(context, 0, self.size.height);
    CGContextScaleCTM(context, 1.0, -1.0);
    CGContextSetBlendMode(context, kCGBlendModeNormal);
    CGRect rect = CGRectMake(0, 0, self.size.width, self.size.height);
    CGContextClipToMask(context, rect, self.CGImage);
    [color1 setFill];
    CGContextFillRect(context, rect);
    UIImage *newImage = UIGraphicsGetImageFromCurrentImageContext();
    UIGraphicsEndImageContext();
    return newImage;
}
