Selecting A Row In An NSTableView Programmatically
提问by Joshua
I want to Select A Row in my table view programmatically, I believe I would use selectRowIndexes:byExtendingSelection:(is this a delegate method?). The other thing is how would I use that method to select the second row (in programming terms row 1)?
我想以编程方式在我的表视图中选择一行，我相信我会使用selectRowIndexes:byExtendingSelection:（这是一种委托方法吗？）。另一件事是我将如何使用该方法来选择第二行（在编程术语中，第 1 行）？
回答by Brad Goss
Joshua, make sure to use the developers documentation to determine whether or not it's a delegate method. If it were a delegate method, it would be mentioned in the docs for NSTableViewDelegate.
Joshua，请务必使用开发人员文档来确定它是否是委托方法。如果它是一个委托方法，它会在 NSTableViewDelegate 的文档中提到。
What you're looking for is very straight forward.
你要找的东西很简单。
Objective-C
目标-C
NSIndexSet *indexSet = [NSIndexSet indexSetWithIndex:1];
[tableview selectRowIndexes:indexSet byExtendingSelection:NO];
Swift 2
斯威夫特 2
let indexSet = NSIndexSet(index: 1)
tableView.selectRowIndexes(indexSet, byExtendingSelection: false)
Again. Make sure to look up the method selectRowIndexes:byExtendingSelection in the docs to see what parameters it needs. It says an NSIndexSet is needed. Then look up NSIndexSet and you'll discover how to use that.
再次。确保在文档中查找方法 selectRowIndexes:byExtendingSelection 以查看它需要哪些参数。它说需要一个 NSIndexSet。然后查找 NSIndexSet，您将发现如何使用它。
