在这个应用程序中，当您选择第二个选项“绿色”时，它将打印“绿色”，但是当您搜索绿色并且它出现在索引0处，并且您单击它时，它将打印“红色”。如何让它打印“绿色”无论在表格视图中哪个索引和行绿色？
感谢...

}
func tableView(tableView: UITableView!, didSelectRowAtIndexPath indexPath: NSIndexPath!) {
if indexPath.row == 1 {
println("green")
}
if indexPath.row == 0 {
println("red")
}
}
答案 0 :(得分：0)
我想出答案......
func tableView(tableView: UITableView!, didSelectRowAtIndexPath indexPath: NSIndexPath!) {
var rownumber = indexPath.row
if dataToDisplay[rownumber] == sampleData[0] {
println("red")
}
}
