在WiFi情况下,网络波动,从网络不可达到有网络状态回调很慢

[983563622]

网络波动(并非切换网络方式),出现网络不可达,但是这是这一点不可达,未来的非常快的一个时间点恢复网络了,触发通知回调很慢(对于这一点的验证:我在网络不可达以后立马通过提供的block获取但网络状态是可达的) 代码如下:

import "RRController.h"

import "RealReachability.h"

@interface RRController ()

@property (weak, nonatomic) IBOutlet UILabel statusLabel; /< 网络状态视图 /

• (IBAction)clickBntForRR:(id)sender;

@end

@implementation RRController

pragma mark - life cycle

• (void)viewDidLoad { [super viewDidLoad];

  [self setupUIForRR]; }

• (void)viewWillAppear:(BOOL)animated { [self refreshNetworkStatus]; }

• (void)dealloc { BKLog(@"");

  [[NSNotificationCenter defaultCenter] removeObserver:self]; }

  pragma mark - event response

• (IBAction)clickBntForRR:(id)sender { UIStoryboard main = [UIStoryboard storyboardWithName:@"Main" bundle:nil]; UIViewController detailController = [main instantiateViewControllerWithIdentifier:@"RRDetailController"];

  if (detailController) { [self.navigationController pushViewController:detailController animated:YES]; } }

  pragma mark - callback

• (void)applicationDidBecomeActive { [self refreshNetworkStatus]; }

• (void)networkChanged:(NSNotification )notification { RealReachability reachability = (RealReachability *)notification.object; ReachabilityStatus status = [reachability currentReachabilityStatus];

  BKLog(@"status = %zd", status);

  [self refreshStatusLabel:status]; }

  pragma mark - private method

• (void)setupUIForRR { // notifications // 监听网络状态 NSNotificationCenter *defaultCenter = [NSNotificationCenter defaultCenter]; [defaultCenter addObserver:self selector:@selector(networkChanged:) name:kRealReachabilityChangedNotification object:nil]; // 监听程序获取焦点 [defaultCenter addObserver:self selector:@selector(applicationDidBecomeActive) name:UIApplicationDidBecomeActiveNotification object:nil]; }

• (void)refreshNetworkStatus { [[RealReachability sharedInstance] reachabilityWithBlock:^(ReachabilityStatus status) { BKLog(@"status = %zd", status);

  [self refreshStatusLabel:status];

  }]; }

• (void)refreshStatusLabel:(ReachabilityStatus)status { switch (status) { case RealStatusNotReachable: { [_statusLabel setBackgroundColor:[UIColor yellowColor]]; [_statusLabel setText:@"无网络!"]; break; } case RealStatusViaWWAN: { [_statusLabel setBackgroundColor:[UIColor greenColor]]; [_statusLabel setText:@"手机网络!"]; break; } case RealStatusViaWiFi: { [_statusLabel setBackgroundColor:[UIColor greenColor]]; [_statusLabel setText:@"WiFi网络!"]; break; } default: break; } }

@end

本来我为演示效果录的是gif动画,不知为何显示成静态图片了...如果需要查看,QQ:983563622,谢谢!

applicationDidBecomeActive 里不需要手动调用reachabilityWithBlock，框架里已经做了处理。我加你qq了，细聊哈
