##Total ###其实实现的功能很简单并且很常用，这个demo只是为了方便大家了解和学习RxSwift ##Demo ###1.Tap #####一个简单的Demo，主要实现了点击按钮，数字加1，长按屏幕，数字加2 ####核心代码如下：
tapBtn.rx.tap.subscribe(onNext:{[weak self] in
let number = Int((self?.numberLabel.text)!)
self?.numberLabel.text = String(number! + 1)
}).disposed(by: disposeBag)
resetBtn.rx.tap.subscribe(onNext:{[weak self] in
self?.numberLabel.text = "0"
}).disposed(by: disposeBag)
longPressGesture.rx.event.subscribe(onNext: { [weak self] _ in
let number = Int((self?.numberLabel.text)!)
self?.numberLabel.text = String(number! + 2)
}).disposed(by: disposeBag)
###2.GetDateAndTime #####获取当地日期和时间，实时更新 ####核心代码如下：
self.refreshBtn.rx.tap.map{ _ in
let dateformatter = DateFormatter()
dateformatter.dateStyle = .medium
dateformatter.timeStyle = .medium
return dateformatter.string(from: Date())
}.bindTo(timeLabel.rx.text)
.addDisposableTo(disposeBag)
###3.DismissKeyBoard #####textView滑动时隐藏键盘，好像模拟器运行有点问题，待解决 ####核心代码如下：
swipeGesture.rx.event.subscribe(onNext:{ [weak self] _ in
self?.view.endEditing(true)
}).addDisposableTo(disposeBag)
###4.AddPhoto #####添加图片，用于平时开发中更换头像 ####核心代码如下：
barButtonItem.rx.tap.flatMapLatest({ [weak self] _ in
return UIImagePickerController.rx.createWithParent(self) { picker in
picker.sourceType = .photoLibrary
picker.allowsEditing = false
}.flatMap({
$0.rx.didFinishPickingMediaWithInfo
}).take(1)
}).map({ info in
return info[UIImagePickerControllerOriginalImage] as? UIImage
}).bindTo(imageView.rx.image)
.disposed(by: disposeBag)
###5.PullToRefresh #####用Rx实现的下拉刷新，大家可以感受一下,同时也加入了删除和移动cell的功能 ####核心代码如下：
items.asObservable().bindTo(tableView.rx.items(cellIdentifier: cellID, cellType: UITableViewCell.self)) { (row, element , cell) in
cell.textLabel?.text = element
}.disposed(by: disposeBag)
refreshControl.rx.controlEvent(.valueChanged).subscribe(onNext: {_ in
items.value = items2
self.refreshControl.endRefreshing()
}).disposed(by: disposeBag)
###6.TableViewTest #####模仿通讯录做的，同时也加入了索引 ####核心代码如下：
dataSource.configureCell = { (_, TestTableView,indexPatch, element) in
let cell = TestTableView.dequeueReusableCell(withIdentifier: self.cell)
cell?.textLabel?.text = element
return cell!
}
dataSource.sectionForSectionIndexTitle = {(dataSource, title , index) -> Int in
return index
}
dataSource.sectionIndexTitles = {ds -> [String]? in
return ds.sectionModels.map({ $0.model})
}
###7.LocalDataTest #####加载本地数据，模仿最近联系人的界面 ####核心代码如下：
dataSource.configureCell = {(_,tv,indexPath,element) in
let cell = tv.dequeueReusableCell(withIdentifier: self.content)
cell?.textLabel?.text = element["name"]
let image = UIImage(named: element["avatar"]!)
let imageSize = CGSize.init(width: 36, height: 36)
UIGraphicsBeginImageContextWithOptions(imageSize, false, 0.0)
let imageRect = CGRect.init(x: 0, y: 0, width: imageSize.width, height: imageSize.height)
image?.draw(in: imageRect)
cell?.imageView?.layer.cornerRadius = 18
cell?.imageView?.layer.masksToBounds = true
cell?.imageView?.image = UIGraphicsGetImageFromCurrentImageContext()
UIGraphicsEndImageContext()
return cell!
}
