1?写一个简单的tableview模版,显示数组里的数据
var ObjectArray = [String]()
var i = 0
override func viewDidLoad() {
super.viewDidLoad()
for i = 0 ; i<10 ; i++ {
self.ObjectArray.append("\(i)")
}
}override func numberOfSectionsInTableView(tableView: UITableView) -> Int {
return 1
}
override func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return ObjectArray.count
}
override func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCellWithIdentifier("cell", forIndexPath: indexPath)
cell.textLabel?.text = "这是第\(self.ObjectArray[indexPath.row])行"
return cell
}
2?添加MJRefresh,并创建桥接文件
将MJRefresh拖到项目中:
创建桥接文件:
new file->source->Header file
在项目-building settings中查找“bridging”设置添加的头文件的路径
并在.h文件中引入第三方库
#import "MJRefresh.h"
3?调用刷新方法
override func viewDidLoad() {
super.viewDidLoad()
for i = 0 ; i<10 ; i++ {
self.ObjectArray.append("\(i)")
}
self.tableView.addLegendHeaderWithRefreshingTarget(self,refreshingAction: "headRefresh")
self.tableView.addGifFooterWithRefreshingTarget(self, refreshingAction: "footRefresh")
}
func headRefresh(){
self.Delay(1, closure: { () -> () in
self.ObjectArray.removeAll(keepCapacity: false)
for self.i = 0 ; self.i < 10 ; self.i++ {
self.ObjectArray.append("\(self.i)")
}
self.tableView.header.endRefreshing()
self.tableView.reloadData()
//self.head.stopRefresh()
})
}
func footRefresh(){
self.Delay(1, closure: { () -> () in
let j = self.i + 10
for self.i = 10 ; self.i < j ; self.i++ {
self.ObjectArray.append("\(self.i)")
}
self.tableView.footer.endRefreshing()
self.tableView.reloadData()
})
}
//延迟函数,模拟服务器延迟
func Delay(time:Double,closure:()->()){
dispatch_after(dispatch_time(DISPATCH_TIME_NOW, Int64(time * Double(NSEC_PER_SEC))), dispatch_get_main_queue(), closure)
}
