Question

我正在导航栏中创建标题视图。我设计了我的标题视图，背景视图颜色为R：255 G：182 B：22（在Photoshop上）。在我的故事板中，我将导航栏色调颜色设置为相同的RGB代码，默认样式和半透明选中。

我使用以下方式将我的图像放在导航标题上：

UIImage *titleImage = [UIImage imageNamed:@"Icon-Small-40.png"];
self.navigationItem.titleView = [[UIImageView alloc]initWithImage:titleImage];

当我运行应用程序时，您可以在标题视图中清楚地看到方形图标。标题视图的背景稍暗。我想让背景颜色相同。我觉得它与某些故事板设置有关，但我找不到问题。

Answer 1

视图有一个tintColor属性，所以

self.navigationItem.titleView.tintColor = ...

        this.toolStrip1.PerformLayout();
        this.ResumeLayout(false);
        this.PerformLayout();

    }

    protected System.Windows.Forms.ToolStrip toolStrip1;
    protected System.Windows.Forms.ToolStripButton loadToolStripButton;

尝试使颜色匹配起来可能令人抓狂。除了颜色空间问题，API无法保证导航栏的实际颜色与其barTintColor相同。您可能会发现更容易为标题图像提供透明背景。
