如何设置按钮的背景颜色 - xcode

Question

如何在Xcode中设置UIButton的背景颜色？

我在布局属性中看到了属性Background和Image，但我无法在这两个中设置任何内容。 （我只能在两种颜色中设置图像）

Answer 1

只需在Attribute Inspector中滚动一下，您就可以在Background部分找到view属性，以便为backgroundColor设置UIButton。

如果要以编程方式设置按钮的backgroundColor。

目标C：

 self.yourButton.backgroundColor = [UIColor redColor];

Swift 3和Swift 4

 self.yourButton.backgroundColor = UIColor.red

Swift 2.3或更低

 self.yourButton.backgroundColor = UIColor.redColor()

如果您正在使用Objective-C，那么这是设置按钮背景颜色的代码。
