UITableView中显示循环的最后一个值 [英] UITableView Showing last value of a loop

问题描述

我想显示回路中的tableview的所有值。在code是来计算表摊销贷款。我试图保存在数组中循环的数据，但它总是给我的最后一个值。我真的卡住了这一点。那么，如何能做到这一点吗？这是我的code：

I would like to show all the values of this loop in the tableview. The code is to calculate an Amortization Table for loans. I tried saving the data of the loop in the array, but it always gives me the last values. I really got stuck on this. So how can I do that, please? This is my code:

import UIKit

class tableViewController: UIViewController, UITableViewDataSource, UITableViewDelegate {

@IBOutlet var tableView: UITableView!

var arr = [Int]()
var cell:tableCell!
var TPayment: float_t! // calls value of 59600 from main controller
var years1: float_t! // number of months = 180 ( 15 years)
var monthlyPayment: float_t! // 471
var interest: float_t! // 5%
var principil: float_t! //222
var interestrate: float_t! // 249
var initil: float_t!
var data = Array<float_t>()
var data2: NSMutableArray = []

override func viewDidLoad() {
    super.viewDidLoad()
    tableView.delegate = self

    tableView.dataSource = self

    let c = Int(years1)
    arr += 0...c

    tableCalculation()

        // Register custom cell
        let nib = UINib(nibName: "table", bundle: nil)
        tableView.registerNib(nib, forCellReuseIdentifier: "cell")
}

func tableCalculation() {
    let years = Int(years1)
    initil = TPayment - 0

    for i in 0..<years {
            initil = initil - principil
            interest = initil * interestrate                
            principil = monthlyPayment - interest                
            print("Month : \(monthlyPayment),   principil: \(principil),interest: \(interest), initi: \(initil)")
            data = [interest]
            self.data2 = [initil]
    }        
}

func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
    return arr.count
}

func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell     {

    cell = tableView.dequeueReusableCellWithIdentifier("cell", forIndexPath: indexPath) as! tableCell
    cell.lbl1.text = "\(arr[indexPath.row])"        
    cell.lbl2.text =  "\(monthlyPayment)"
    cell.lbl3.text = "\(data[indexPath.row % data.count])"
    cell.lbl4.text = "\(principal)"
    cell.lbl5.text = "\(self.data2[indexPath.section])"        
    return cell        
}    

func tableView(tableView: UITableView, didSelectRowAtIndexPath indexPath: NSIndexPath) {
    print("Row \(indexPath.row) selected")
}

func tableView(tableView: UITableView, heightForRowAtIndexPath indexPath: NSIndexPath) -> CGFloat {
    return 40
}
}

推荐答案

的主要问题是与您的数据阵列。

The main issue is with your data array.

在你的循环，你填充您的数据阵列，在 tableCalculation ，有这样的：

In your loop where you populate your data array, in tableCalculation, there's this:

data = [interest]

这意味着对于每个迭代您的设置的数据阵列 [利益] 代替的追加的新项到阵列

It means that for each iteration you set the data array to [interest] instead of appending the new item to the array.

你应该做的，而不是：

data.append(interest)

需要注意的是你与 self.data2 同样的错误。但现在你知道如何解决这样那样的错误。

Note that you make the same mistake with self.data2. But now you know how to fix this kind of error.
