iOS擷取網路的最新方法(自己試了下沒什麼問題)

標籤：ios   網路   wifi   typedef   

typedef enum {   NETWORK_TYPE_NONE= 0,   NETWORK_TYPE_WIFI= 1,   NETWORK_TYPE_3G= 2,   NETWORK_TYPE_2G= 3,
}NETWORK_TYPE;
然後通過擷取手機訊號欄上面的網路類型的標誌
+ (int)dataNetworkTypeFromStatusBar {   UIApplication *app = [UIApplicationsharedApplication];   NSArray *subviews = [[[app valueForKey:@"statusBar"] valueForKey:@"foregroundView"] subviews];   NSNumber *dataNetworkItemView = nil;   for (id subview in subviews) {       if([subview isKindOfClass:[NSClassFromString(@"UIStatusBarDataNetworkItemView") class]]) {           dataNetworkItemView = subview;           break;       }   }int netType = NETWORK_TYPE_NONE;NSNumber * num = [dataNetworkItemView valueForKey:@"dataNetworkType"];if (num == nil) {       netType = NETWORK_TYPE_NONE;   }else{int n = [num intValue];if (n == 0) {           netType = NETWORK_TYPE_NONE;       }elseif (n == 1){           netType = NETWORK_TYPE_2G;       }elseif (n == 2){           netType = NETWORK_TYPE_3G;       }else{           netType = NETWORK_TYPE_WIFI;       }   }return netType;}
如果發現問題，請及時告知，謝謝！
