我认为问题是由于有相同的
数据源阵列
在您的案例中
postsArray
postsArray公司
postsArray公司
section 0
,
section 1
抱怨插入操作前后我的行数不一样,但
第0节
不要抱怨,因为它在中具有相同的行数和项数
现在这个问题可以通过两种方式解决:
postsArray公司
postsArray1
对于第1节,
postsArray2
class ViewController: UIViewController, UITableViewDataSource, UITableViewDelegate {
@IBOutlet weak var tableView: UITableView!
override func viewDidLoad() {
super.viewDidLoad()
let addButton = UIBarButtonItem(barButtonSystemItem: .add, target: self, action: #selector(buttonTapped(_:)))
self.navigationItem.rightBarButtonItem = addButton
}
var valuesFirstSection = ["value1", "value2", "value3"]
var valuesSecondSection = ["value1Second", "value2Second", "value3Second"]
//if you want to have the same dataSource array then use this
//var sharedValues = ["value1Shared", "value2Shared", "value3Shared"] // shared dataSource array
func numberOfSections(in tableView: UITableView) -> Int {
return 2
}
func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
if section == 0 {
return valuesFirstSection.count
}else {
return valuesSecondSection.count
}
// //if you want to have the same dataSource array then
//use this
//return sharedValues.count;
}
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCell(withIdentifier: "Cell", for: indexPath)
if indexPath.section == 0 {
cell.textLabel?.text = valuesFirstSection[indexPath.row]
}else {
cell.textLabel?.text = valuesSecondSection[indexPath.row]
}
return cell
//if you want to have the same dataSource array then
//use this
//cell.textLabel?.text = sharedValues[indexPath.row]
//return cell
}
func buttonTapped(_ sender: UIBarButtonItem) {
//if you want to have the same dataSource array then
//you need to insert the rows for other sections as well
// sharedValues.insert("NewValue0", at: 0)
// self.tableView.insertRows(
// at: [IndexPath(row: 0, section: 0),
// IndexPath(row: 0, section: 1)
// ],
// with: .automatic)
valuesFirstSection.insert("NewValue0", at: 0)
self.tableView.insertRows(
at: [IndexPath(row: 0, section: 0)
],
with: .automatic)
}
}
希望这有帮助。
