基于AFNetworking封裝的下載管理類

從自己剛開始做項(xiàng)目時(shí)，一直都是用AFNetworking進(jìn)行網(wǎng)絡(luò)請(qǐng)求。每次涉及網(wǎng)絡(luò)請(qǐng)求的時(shí)候都手寫一次，寫的整個(gè)人都不好不好了。特別AFNetworking升級(jí)3.0的時(shí)候真想剁了自己的手。從那以后只要是第三方的我基本都是自己做一層封裝。廢話不多說下面來聊聊下載類的封裝。

所謂下載管理類：無非就是，在對(duì)AFNetworking封裝便用的時(shí)候，在進(jìn)行一次對(duì)下載工具的封裝。這樣的好處有以下幾點(diǎn)：

  1. 同一個(gè)網(wǎng)址的數(shù)據(jù)請(qǐng)求只會(huì)進(jìn)行一次。 例如用戶對(duì)TableView的瘋狂下拉刷新 數(shù)據(jù)源處理不好可能會(huì)崩潰。
  2. 控制器消失的時(shí)候取消當(dāng)前數(shù)據(jù)請(qǐng)求。 AFNetworking進(jìn)行數(shù)據(jù)請(qǐng)求，如果不手動(dòng)取消請(qǐng)求的話在控制器銷毀的時(shí)候此次任務(wù)還是存在的。當(dāng)請(qǐng)求完成的時(shí)候走回調(diào)Block這就有崩潰的危險(xiǎn)存在。當(dāng)初這里理解了，當(dāng)AF請(qǐng)求沒有完成就pop的話，由于AF引用當(dāng)前界面，所以當(dāng)前界面不會(huì)釋放。直至完成才會(huì)釋放故不存在crash一說。返回只是節(jié)省用戶流量罷了。

文件中的注釋已經(jīng)很詳細(xì)了，在這里就不多做贅述了。
有個(gè)要注意的是`AFNetworking` 手動(dòng)取消下載也會(huì)執(zhí)行下載失敗的回調(diào)，打印`error`為
```Error Domain=NSURLErrorDomain Code=-999 "已取消" UserInfo={NSErrorFailingURLKey=http://172.16.10.34:8080/wisdomCampus_interface/assessment/queryList?flag=1&pageindex=1&pagesize=10&token=932b80a56a38bcc1b22796c2fdf57383, NSLocalizedDescription=已取消, NSErrorFailingURLStringKey=http://172.16.10.34:8080/wisdomCampus_interface/assessment/queryList?flag=1&pageindex=1&pagesize=10&token=932b80a56a38bcc1b22796c2fdf57383}```
可以利用`error ==-999`來判斷是不是取消下載執(zhí)行的失敗回調(diào)。

之前的
```UIViewController * VC =   [self popViewControllerAnimated:YES];
//這里打印的是剛剛出棧的VC 
    QMLog(@"%@",VC);
    [[QQNetManager defaultManager] deleteConnectionVC:VC]```
會(huì)有一個(gè)問題  就是當(dāng)我A界面push進(jìn)B界面，然后迅速（就是很快很快）pop回B界面，雖然返回成功但是`popViewControllerAnimated:YES` 的返回值是`nil`之前在`- (void)deleteConnectionVC:(UIViewController *)vc
`里面沒有做空的判斷因此會(huì)崩潰。不過此時(shí)`viewControllers`里面是有B界面的。所以現(xiàn)在用`    [[QQNetManager defaultManager] deleteConnectionVC:self.viewControllers.lastObject];
`來取值
##2017.03.18日更新內(nèi)容
`popViewControllerAnimated:YES `返回為nil，大概是因?yàn)閜op動(dòng)畫沒有完成的造成的。與之相關(guān)聯(lián)的章[我是傳送門點(diǎn)我進(jìn)入](http://blog.lessfun.com/blog/2015/09/09/uiviewcontroller-push-pop-trap/)
