在这篇博文中你可以看到那些内容呢, 首先这是一个用tableView纯代码Swift写的简单界面, 你可以看到下面这些

使用Alamofire 进行网络请求
使用MJExtension 进行字典转模型
使用HanekeSwift 进行图片的赋值
如何写一个模型(M)
如何自定义一个UITableViewCell

Alamofire 简单网络请求

func XTNetworkReq(url: String){

print("SUMMER_TEST_1")

Alamofire.request(.GET, url, parameters: nil)

.validate(contentType: ["application/json", "text/json", "text/javascript", "text/html","text/css", "text/plain","application/x-javascript"])

.responseJSON { response in

switch response.result {

case .Success:

// print("Validation Successful: \(response.result.value)")

// json 转化成字典

// 并进行数据解析

let jsonDataDic = response.result.value as? NSDictionary

let dataDic = jsonDataDic?.objectForKey("data")

let listArray = dataDic?.objectForKey("list")

print(listArray)

// 字典转模型(MJExtension)

self.dataArray = AlamofireVCModel.mj_objectArrayWithKeyValuesArray(listArray)

if self.dataArray.count > 0

{

// 进行UI刷新操作

self.tableView.reloadData()

}

case .Failure(let error):

print(error)

}

如何写一个模型

class AlamofireVCModel: NSObject {

var id: Int = 0

var title: String?

var pic: String?

var readnum: String?

var replynum: String?

}

如何自定义一个Cell

var alaModel = AlamofireVCModel()

var imagePic = UIImageView()

var labelTitle = UILabel()

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

super.init(style: UITableViewCellStyle.Default, reuseIdentifier: reuseIdentifier)

self.createCellSubviews()

}

required init?(coder aDecoder: NSCoder) {

fatalError("init(coder:) has not been implemented")

}

// MARK: - 布局UI

func createCellSubviews(){

imagePic = UIImageView.init(frame: CGRectMake(5, 5, self.contentView.frame.size.width - 10, 188 - 10))

self.contentView.addSubview(imagePic)

labelTitle = UILabel.init(frame: CGRectMake(10, 10, s_w, 60))

labelTitle.numberOfLines = 0

labelTitle.textColor = UIColor ( red: 1.0, green: 0.4666, blue: 0.3002, alpha: 1.0 )

imagePic.addSubview(labelTitle)

}

// MARK: - layoutSubviews

override func layoutSubviews() {

if (self.alaModel.pic != nil && self.alaModel.pic?.hasSuffix("gif") != nil){

// 进行图片的赋值, 这里给出的截取字符串的方法

self.imagePic.hnk_setImageFromURL(NSURL.init(string: (self.alaModel.pic?.substringToIndex((self.alaModel.pic?.startIndex.advancedBy(66))!))!)!)

}

self.labelTitle.text = self.alaModel.title

}
