更改標簽欄的色彩顏色編輯視圖控制器

Question

我想更改選項卡欄控制器的“編輯”視圖控制器的顏色。 我已經設法更改顏色以使用更多視圖控制器，但對此沒有任何提示。

這段代碼是為了更改更多視圖控制器的顏色，這些顏色寫在UITabBarController的subcalss中

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

歡迎對Objective-C或Swift提出建議

Answer 1

通過嘗試以下代碼為我工作

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

Answer 2

您可以為tabBarItem設置手動彩色圖像。

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];
        }

以下功能可用於手動着色圖像

- (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;
}
