是否可以自动布局UISlider的宽度

Question

我正在使用PureLayout将UISlider放在两个按钮之间，如下所示：

[self.slider autoPinEdge:ALEdgeLeading  toEdge:ALEdgeTrailing   ofView:self.leftButton withOffset:10.0f];
[self.slider autoPinEdge:ALEdgeTrailing toEdge:ALEdgeLeading    ofView:self.rightButton withOffset:10.0f];
[self.slider autoAlignAxisToSuperviewAxis:ALAxisHorizontal];

UISlider是否有可能在leftButton和rightButton之间自动设置其宽度？

Answer 1

要自动布局UISlider的宽度，您应该提供左右按钮的宽度。此外，您必须将它们固定到超视图边缘。然后你就可以将滑块的LEFT边缘固定到leftButton的右边缘，将滑块的右边缘固定到rightButton的左边缘。

示例代码：

cell.contentView.addSubview(leftButton)
cell.contentView.addSubview(slider)
cell.contentView.addSubview(rightButton)

rightButton.autoPinEdgeToSuperviewEdge(.Top)
rightButton.autoPinEdgeToSuperviewEdge(.Right)
rightButton.autoSetDimension(.Width, toSize: 100)
rightButton.autoSetDimension(.Height, toSize: 50)

leftButton.autoPinEdgeToSuperviewEdge(.Top)
leftButton.autoPinEdgeToSuperviewEdge(.Left)
leftButton.autoSetDimension(.Width, toSize: 100)
leftButton.autoSetDimension(.Height, toSize: 50)

slider.autoPinEdge(.Leading, toEdge: .Trailing, ofView: leftButton, withOffset : 5)
slider.autoPinEdge(.Trailing, toEdge: .Leading, ofView: rightButton, withOffset : -5)
slider.autoPinEdgeToSuperviewEdge(.Top)
