首先看一个gif动画:
直观的感受一下,这个项目有哪些东东
然后这里,你可以学到哪些东西:
1、如何使用UITableview来展示从网络上拉去的 JsonArray数据。
2、如何自定义一个Cell,并且使用到列表视图中去。
collectionView.registerNib(UINib.init(nibName: String(MeiZiCollectionViewCell.self), bundle: nil), forCellWithReuseIdentifier: indentifer)
3、Alamofire 大神级网络加载框架的使用
private func loadData() {
UIApplication.sharedApplication().networkActivityIndicatorVisible = true
self.view.makeToastActivity(.Center)
Alamofire.request(.GET,
APIUtils.IOS_URL.stringByReplacingOccurrencesOfString("num", withString: String(pageNum)).stringByReplacingOccurrencesOfString("pageindex", withString: String(currentPageIndex))).responseSwiftyJSON { [unowned self](response) in
if response.result.isSuccess {
if response.result.value!["error"].boolValue == false {
if let dataArr = response.result.value!["results"].array {
dataArr.forEach({ (jsonobj) in
let iosdata = IOSData()
iosdata.author = jsonobj["who"].stringValue
iosdata.desc = jsonobj["desc"].stringValue
iosdata.url = jsonobj["url"].stringValue
self.dataList.append(iosdata)
})
self.tableView.reloadData()
}
}
}
self.tableView.mj_footer.endRefreshing();
self.tableView.mj_header.endRefreshing();
UIApplication.sharedApplication().networkActivityIndicatorVisible = false
self.view.hideToastActivity()
}
}
4、PromiseKit的使用方式demo
private func loadData() {
UIApplication.sharedApplication().networkActivityIndicatorVisible = true
self.view.makeToastActivity(.Center)
firstly {
when(NSURLSession.GET(APIUtils.ANDROID_URL.stringByReplacingOccurrencesOfString("num", withString: String(pageNum)).stringByReplacingOccurrencesOfString("pageindex", withString: String(currentPageIndex))).asDictionary())
}.then { [unowned self] data -> Void in
self.currentPageIndex = self.currentPageIndex + 1
guard let error = data[0]["error"] as? Int else {
return;
}
// 请求成功
if error == 0 {
guard let results = data[0]["results"] as? NSArray else {
print("fetal_error")
return;
}
if self.currentPageIndex == 1 {
self.dataList.removeAll()
}
results.forEach({ (item) in
if let dic = item as? NSDictionary {
let androidData = AndroidData()
androidData.author = dic["who"] as? String
androidData.desc = dic["desc"] as? String
androidData.url = dic["url"] as? String
self.dataList.append(androidData)
}
})
self.tableView.reloadData()
}
}.always {
UIApplication.sharedApplication().networkActivityIndicatorVisible = false
self.tableView.mj_header.endRefreshing()
self.tableView.mj_footer.endRefreshing()
self.view.hideToastActivity()
}.error { [unowned self] error in
let alert = UIAlertController.init(title: "提示", message: "\(error)", preferredStyle: .Alert)
self.presentViewController(alert, animated: true, completion: {
})
}
}
5、RxSwift使用的demo
private func loadData() {
UIApplication.sharedApplication().networkActivityIndicatorVisible = true
self.view.makeToastActivity(.Center)
let request = NSURLRequest.init(URL: NSURL.init(string: APIUtils.FULI_URL.stringByReplacingOccurrencesOfString("num", withString: String(pageNum)).stringByReplacingOccurrencesOfString("pageindex", withString: String(currentPageIndex)))!)
if currentPageIndex == 1 {
self.dataList.removeAll()
}
let responseJSON = NSURLSession.sharedSession().rx_JSON(request)
let cancelRequest = responseJSON
// .subscribeOn(ImmediateSchedulerT)
.observeOn(MainScheduler.instance)
.map({ (data) -> [MeiZiData] in
var meiziDatas = [MeiZiData]()
let json = JSON(data)
if json["error"].boolValue == false {
if let dataArr = json["results"].array {
dataArr.forEach({ (jsonobj) in
let meiziData = MeiZiData()
meiziData.pubTime = jsonobj["publishedAt"].stringValue
meiziData.url = jsonobj["url"].stringValue
meiziDatas.append(meiziData)
})
}
}
return meiziDatas
})
.subscribe(onNext: { [unowned self] data in
self.dataList.appendContentsOf(data)
self.collectionView.reloadData()
self.currentPageIndex = self.currentPageIndex + 1
}, onError: { (error) in
UIApplication.sharedApplication().networkActivityIndicatorVisible = false
self.view.hideToastActivity()
self.collectionView.mj_header.endRefreshing()
self.collectionView.mj_footer.endRefreshing()
}, onCompleted: {
UIApplication.sharedApplication().networkActivityIndicatorVisible = false
self.view.hideToastActivity()
self.collectionView.mj_header.endRefreshing()
self.collectionView.mj_footer.endRefreshing()
}) {
UIApplication.sharedApplication().networkActivityIndicatorVisible = false
self.view.hideToastActivity()
self.collectionView.mj_header.endRefreshing()
self.collectionView.mj_footer.endRefreshing()
}
6、列表的MJRefresh上拉帅新下来加载更多
为什么要使用这么一句?
collectionView.contentInset = UIEdgeInsets.init(top: -60, left: 0, bottom: -44, right: 0)
7、MWPhotoBrowser实现图片长廊的demo
private func showImageDetail(currentIndex: Int) {
let browser = MWPhotoBrowser.init(delegate: self)
photos.removeAll()
dataList.forEach { (data) in
let photo = MWPhoto.init(URL: NSURL.init(string: data.url!))
photos.append(photo)
}
browser.displayActionButton = true; // Show action button to allow sharing, copying, etc (defaults to YES)
browser.displayNavArrows = false; // Whether to display left and right nav arrows on toolbar (defaults to NO)
browser.displaySelectionButtons = false; // Whether selection buttons are shown on each image (defaults to NO)
browser.zoomPhotosToFill = true; // Images that almost fill the screen will be initially zoomed to fill (defaults to YES)
browser.alwaysShowControls = false; // Allows to control whether the bars and controls are always visible or whether they fade away to show the photo full (defaults to NO)
browser.enableGrid = true; // Whether to allow the viewing of all the photo thumbnails on a grid (defaults to YES)
browser.startOnGrid = false; // Whether to start on the grid of thumbnails instead of the first photo (defaults to NO)
browser.autoPlayOnAppear = false; // Auto-play first video
browser.setCurrentPhotoIndex(1)
self.navigationController?.pushViewController(browser, animated: true)
browser.setCurrentPhotoIndex(UInt(currentIndex))
browser.showNextPhotoAnimated(true)
browser.showPreviousPhotoAnimated(true)
browser.setCurrentPhotoIndex(UInt(currentIndex))
}
