Swift2 由于未捕获异常“NSInternalInconsistencyException”而终止应用程序，原因：“无效的indexPath”

斯威夫特2号正在干掉我的脑袋

我改编了：

func addConstraints(format format: String, options: NSLayoutFormatOptions? = nil, metrics: [String: AnyObject]? = nil, views: [String: UIView]) {
    addConstraints(NSLayoutConstraint.constraintsWithVisualFormat(format, options: options!, metrics: metrics, views: views))
}

func addUniversalConstraints(format format: String, options: NSLayoutFormatOptions, metrics: [String: AnyObject]? = nil, views: [String: UIView]) {
    addConstraints(format: "H:\(format)", options: options, metrics: metrics, views: views)
    addConstraints(format: "V:\(format)", options: options, metrics: metrics, views: views)
}

虽然没有，但我在这行有个错误

public func selectRowAtIndex(index: Index) {
    selectedRowIndex = index

    tableView.selectRowAtIndexPath(
        NSIndexPath(forRow: index, inSection: 0),
        animated: false,
    /**Error->*/    scrollPosition: .Middle)
}

如果你能帮忙，再次感谢你

是否设置了断点并检查了值是否有效？没有解决方案，但最好将NSLayoutFormatOptions声明为可选，并使用默认的nil值，然后强制展开该值。替换选项：NSLayoutFormatOptions？=带有选项的nil:NSLayoutFormatOptions=NSLayoutFormatOptions如果您确实需要默认值，我将scrollPosition:.Middle更改为scrollPosition:.None作为解决方法解决了此问题
