基本上，我需要在mySQL数据库和Swift应用程序之间建立安全连接。理想情况下，我需要使表格数据出现在快速表格视图中。
虽然我已经使用PHP脚本在mySQL数据库和Swift应用程序之间建立了连接，但是当转到正确的地址（www.example.com/service.php）时，我不能只在网站上显示此信息。
重要的是，PHP脚本只能为我的移动应用程序加载，而不能为任何其他人加载。
当前，这是我在Swift App和PHP脚本中用于访问数据库的代码。
我可以对代码进行哪些更改？欢迎任何建议，我非常感谢。
Swift应用程序：
FirstViewController：
private boolean areFourConnected(){
for (int j = 0; j<rows-3 ; j++ ){
for (int i = 0; i<columns; i++){
if (this.cells[i][j].getPlayer() == cells[i][j].getPlayer() && this.cells[i][j+1].getPlayer() == cells[i][j].getPlayer() && this.cells[i][j+2].getPlayer() == cells[i][j].getPlayer() && this.cells[i][j+3].getPlayer() == cells[i][j].getPlayer()){
return true;
}
}
}
for (int i = 0; i<columns-3 ; i++ ){
for (int j = 0; j<this.rows; j++){
if (this.cells[i][j].getPlayer() == cells[i][j].getPlayer() && this.cells[i+1][j].getPlayer() == cells[i][j].getPlayer() && this.cells[i+2][j].getPlayer() == cells[i][j].getPlayer() && this.cells[i+3][j].getPlayer() == cells[i][j].getPlayer()){
return true;
}
}
}
for (int i=3; i<columns; i++){
for (int j=0; j<rows-3; j++){
if (this.cells[i][j].getPlayer() == cells[i][j].getPlayer() && this.cells[i-1][j+1].getPlayer() == cells[i][j].getPlayer() && this.cells[i-2][j+2].getPlayer() == cells[i][j].getPlayer() && this.cells[i-3][j+3].getPlayer() == cells[i][j].getPlayer())
return true;
}
}
for (int i=3; i<columns; i++){
for (int j=3; j<rows; j++){
if (this.cells[i][j].getPlayer() == cells[i][j].getPlayer() && this.cells[i-1][j-1].getPlayer() == cells[i][j].getPlayer() && this.cells[i-2][j-2].getPlayer() == cells[i][j].getPlayer() && this.cells[i-3][j-3].getPlayer() == cells[i][j].getPlayer())
return true;
}
}
return false;
}
FeedModel.swift：
import UIKit
class FirstViewController: UIViewController, UITableViewDataSource, UITableViewDelegate, FeedModelProtocol {
var feedItems: NSArray = NSArray()

// Configure our cell title made up of name and price
let titleStr: String = item.manufacturer! + ": " + item.model!
print(titleStr)
// Get references to labels of cell
myCell.textLabel!.text = titleStr
return myCell
}
}
StockModel：
import Foundation

var jsonElement = NSDictionary()
let stocks = NSMutableArray()
for i in 0 ..< jsonResult.count

//the following insures none of the JsonElement values are nil through optional binding

stock.model = price
}
stocks.add(stock)

DispatchQueue.main.async(execute: { () -> Void in
self.delegate.itemsDownloaded(items: stocks)

}
PHP脚本：
import UIKit
class StockModel: NSObject {
//properties of a stock
var manufacturer: String?
var model: String?
//empty constructor
override init()

//construct with @name and @price parameters

//prints a stock's name and price
override var description: String {
return "Name: \(String(describing: manufacturer)), Address: \(String(describing: model))"
}
