我有一个包含完整字母表的部分索引 - 然而，我表格中的部分仅包含几个字母(例如 C、F、N、U)。
我想修改 sectionForSectionIndexTitle 以在将手指滑过部分索引时正确显示正确的部分。我仍然不确定如何使用 sections.append...
谢谢你的帮助。
我的代码是这样的:
Section.swift
struct Section
{
var heading : String
var items : [String]
init(title: String, objects : [String]) {
heading = title
items = objects
}
}
ViewController.swift
func updateSections(index : Int) {
switch index {
case 0:
sections.append(Section(title: "C", objects: ["Czech Republic"]))
sections.append(Section(title: "F", objects: ["France"]))
sections.append(Section(title: "N", objects: ["Norway"]))
sections.append(Section(title: "U", objects: ["USA"]))
default: break
}
tableViewOutlet.reloadData()
}
let arrIndexSection = ["A","B","C","D", "E", "F","G","H","I","J","K","L","M","N","O","P","Q","R","S","T","U","V","W","X","Y","Z"]
func sectionIndexTitlesForTableView(tableView: UITableView) -> [String]? {
if segmentedControlOutlet.selectedSegmentIndex == 0 {
return arrIndexSection
} else {
return [""]
}
}
func tableView(tableView: UITableView, sectionForSectionIndexTitle title: String, atIndex index: Int) -> Int {
let temp = arrIndexSection as NSArray
return temp.indexOfObject(title)
}
func numberOfSectionsInTableView(tableView: UITableView) -> Int {
return sections.count
}
func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
let section = sections[section]
return section.items.count
}
func tableView(tableView: UITableView, titleForHeaderInSection section: Int) -> String? {
return sections[section].heading
}
最佳答案
在您的项目中尝试以下代码:
func tableView(tableView: UITableView, sectionForSectionIndexTitle title: String, atIndex index: Int) -> Int {
var tempIndex:Int = 0
for str in arrIndexSection {
if str == title {
return tempIndex
}
tempIndex += 1
}
return 0
}
