先上效果图
再上源码
1. 对于URLSession做了个简单的封装，用来请求网络数据
import Foundation
class LJDownLoadNetImage: NSObject {
static func request(_ method: String,url: String,callback: @escaping (_ data: Data?,_ response: URLResponse?,_ error: Error?) -> Void) {
let session = URLSession.shared
let request = NSMutableURLRequest(url: NSURL(string: url)! as URL)
request.httpMethod = method
let task = session.dataTask(with: request as URLRequest,completionHandler: { (data,response,error) -> Void in
callback(data,error)
})
task.resume()
}
}
import UIKit
class TFNetImageViewController: TFBaseViewController,UITableViewDataSource,UITableViewDelegate{
var TFTableView:UITableView!
var titleItemArray = ["姓名","账号","爱好","职业","年薪"]
var imageUrlArray = ["http://pica.nipic.com/2007-12-12/20071212235955316_2.jpg","http://hangge.com/blog/images/logo.png","https://www.iphonetrain.com/core/res/images/logo.png","http://pica.nipic.com/2007-12-12/20071212235955316_2.jpg","http://pica.nipic.com/2007-12-12/20071212235955316_2.jpg"];
override func viewDidLoad() {
super.viewDidLoad()
self.setTopNavBarTitle("个人信息")
self.setTopNavBackButton()
self.view.backgroundColor = UIColor.lightGray
self.creatTable()
}
func creatTable(){
TFTableView = UITableView(frame: CGRect(x: 0,y: 64,width: AppWidth,height: AppHeight - 64),style:UITableViewStyle.grouped);
TFTableView.delegate = self;
TFTableView.dataSource = self;
self.view.addSubview(TFTableView);
TFTableView.register(TFNetImageTableViewCell.self,forCellReuseIdentifier: "identtifier")
}
//MARK: UITableViewDataSource
func numberOfSections(in tableView: UITableView) -> Int {
return 1;
}

cell.setCellData(titleItemArray[indexPath.row],imageUrlStr: urlStr)
return cell

tableView.deselectRow(at: indexPath,animated: true);
}
}
cell的代码
import UIKit

override init(style: UITableViewCellStyle,reuseIdentifier: String?) {

// Configure the view for the selected state
}
func creatCell(){
//http://pica.nipic.com/2007-12-12/20071212235955316_2.jpg
//设置label

*/
/*
2. 加载网络图片
*/
/*
//定义NSURL对象
