如何调整UITableView宽度以适应其内容？

Is there possible way to adjust table view width by width of biggest text that should be set in the cellTitle label?

是否有可能通过cellTitle标签中设置的最大文本宽度调整表视图宽度?

Set a width auto-layout constraint to the table view.

将宽度自动布局约束设置为表视图。

Set an outlet from the constraint to your code (ctrl+drag, just like a view).

将约束的出口设置为代码(ctrl + drag,就像视图一样)。

When you have the size of the label (if the label also has auto-layout then you will have it at viewDidLayoutSubviews) set the width to the table like so:

如果你有标签的大小(如果标签也有自动布局,那么你将在viewDidLayoutSubviews上)将宽度设置为表,如下所示:
```
- (void)viewDidLayoutSubviews {
    self.myTableWidthConstraint.constant = self.myLabel.frame.size.width;  
    [self.myTableView updateConstraints];  
    [self.myTableView layoutIfNeeded];
}
```

#2

public override func viewDidLayoutSubviews() {
    super.viewDidLayoutSubviews()

    // Set the popover tableview width to be max compressed size (assumes all cells visible)
    let maxWidth = tableView.visibleCells.reduce(0.0) { (currentMax, cell) -> CGFloat in
        return max(currentMax, cell.contentView.systemLayoutSizeFittingSize(UILayoutFittingCompressedSize).width)
    }

    var contentSize = tableView.contentSize
    contentSize.width = maxWidth
    tableView.contentSize = contentSize
    tableView.bounds.size = contentSize
}

#3

You can achieve it by writing 2 lines in your viewDidLoad :

您可以通过在viewDidLoad中写入2行来实现它:

   //what ever you want the estimated row height
    self.tableView.estimatedRowHeight = 280
    self.tableView.rowHeight = UITableViewAutomaticDimension

Note : its only applied for IOS 8

注意:它仅适用于IOS 8

You should be able to do that in the size inspector.

您应该能够在尺寸检查器中执行此操作。
