NSURLConnection包装方法

监听进度
/* 要跟踪进度，需要使用 NSProgress，是在 iOS 7.0 推出的，专门用来跟踪进度的类！ NSProgress只是一个对象！如何跟踪进度！-> KVO 对属性变化的监听！ @property int64_t totalUnitCount; 总单位数 @property int64_t completedUnitCount; 完成单位数 */ NSProgress *progress = nil; // 注册通知 [progress addObserver:self forKeyPath:@"completedUnitCount" options:NSKeyValueObservingOptionNew context:nil]; - (void)observeValueForKeyPath:(NSString *)keyPath ofObject:(id)object change:(NSDictionary *)change context:(void *)context { NSLog(@"%@", object); /** 准确的获得进度 localizedDescription 10% localizedAdditionalDescription completed 32,768 of 318,829 fractionCompleted 0.102776(completedUnitCount/totalUnitCount) */ if ([object isKindOfClass:[NSProgress class]]) { NSProgress *p = (NSProgress *)object; NSLog(@"%@, %@, %f", p.localizedDescription, p.localizedAdditionalDescription, p.fractionCompleted);

AFN解耦
序列化
/ 1.创建网络监听对象 AFNetworkReachabilityManager *manager = [AFNetworkReachabilityManager sharedManager]; // 2.设置网络状态改变回调 [manager setReachabilityStatusChangeBlock:^(AFNetworkReachabilityStatus status) { /* AFNetworkReachabilityStatusUnknown = -1, // 未知 AFNetworkReachabilityStatusNotReachable = 0, // 无连接 AFNetworkReachabilityStatusReachableViaWWAN = 1, // 3G 花钱 AFNetworkReachabilityStatusReachableViaWiFi = 2, // 局域网络,不花钱 */ switch (status) { case 0: NSLog(@"无连接"); break; case 1: NSLog(@"3G 花钱"); break; case 2: NSLog(@"局域网络,不花钱"); break; default: NSLog(@"未知"); break; } }]; // 3.开始监听 [manager startMonitoring];
- (void)viewDidLoad { [super viewDidLoad]; // 注册通知 [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(getNetworkStatus) name:kReachabilityChangedNotification object:nil]; // 开始监听网络 self.reachability = [Reachability reachabilityForInternetConnection]; [self.reachability startNotifier]; } - (void)dealloc { [[NSNotificationCenter defaultCenter] removeObserver:self]; [self.reachability stopNotifier]; } - (void)getNetworkStatus{ if ([Reachability reachabilityForLocalWiFi].currentReachabilityStatus != NotReachable) { NSLog(@"wifi"); }else if ([Reachability reachabilityForInternetConnection].currentReachabilityStatus != NotReachable) { NSLog(@"手机自带网络"); }else { NSLog(@"没有网络"); } }
CocoaPods安装东西的时候它要找到Xcode的Developer文件夹, 如果找不到会报如下错误
解决方案
sudo xcode-select --switch /Users/JX/Applications/Xcode.app/Contents/Developer
