indexPath.row 有更短的使用方法吗？我目前正在使用它:
func tableView(tableView: UITableView, didSelectRowAtIndexPath indexPath: NSIndexPath) {
if indexPath.row == 0 {
self.performSegueWithIdentifier("0", sender: self)
tableView.deselectRowAtIndexPath(indexPath, animated: true)
} else if indexPath.row == 1 {
self.performSegueWithIdentifier("1", sender: self)
tableView.deselectRowAtIndexPath(indexPath, animated: true)
} else if indexPath.row == 2 {
self.performSegueWithIdentifier("2", sender: self)
tableView.deselectRowAtIndexPath(indexPath, animated: true)
} else if indexPath.row == 3 {
self.performSegueWithIdentifier("3", sender: self)
tableView.deselectRowAtIndexPath(indexPath, animated: true)
} else if indexPath.row == 4 {
self.performSegueWithIdentifier("4", sender: self)
tableView.deselectRowAtIndexPath(indexPath, animated: true)
} else if indexPath.row == 5 {
self.performSegueWithIdentifier("5", sender: self)
tableView.deselectRowAtIndexPath(indexPath, animated: true)
} else if indexPath.row == 6 {
self.performSegueWithIdentifier("6", sender: self)
tableView.deselectRowAtIndexPath(indexPath, animated: true)
} else if indexPath.row == 7 {
self.performSegueWithIdentifier("7", sender: self)
tableView.deselectRowAtIndexPath(indexPath, animated: true)
} else if indexPath.row == 8 {
self.performSegueWithIdentifier("8", sender: self)
tableView.deselectRowAtIndexPath(indexPath, animated: true)
} else if indexPath.row == 9 {
self.performSegueWithIdentifier("9", sender: self)
tableView.deselectRowAtIndexPath(indexPath, animated: true)
} else if indexPath.row == 10 {
self.performSegueWithIdentifier("10", sender: self)
tableView.deselectRowAtIndexPath(indexPath, animated: true)
}
}
我实际上在我的项目中使用了 42 条 indexPath.row 语句，但我只举了上面的 11 条作为示例。
最佳答案
你可以这样做
func tableView(tableView: UITableView, didSelectRowAtIndexPath indexPath: NSIndexPath) {
self.performSegueWithIdentifier(String(indexPath.row), sender: self)
tableView.deselectRowAtIndexPath(indexPath, animated: true)
}
关于ios - 有没有更短的方法来使用 indexPath.row？，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/34582574/
