IOS通过状态栏的显示获取对应的网络状态

NSArray *subviews = [[[[UIApplication sharedApplication] valueForKeyPath:@"statusBar"] valueForKeyPath:@"foregroundView"] subviews];

for (id child in subviews) {

if ([child isKindOfClass:NSClassFromString(@"UIStatusBarDataNetworkItemView")]) {

//获取到状态栏码

int networkType = [[child valueForKeyPath:@"dataNetworkType"] intValue];

NSLog(@"networkType = %d",networkType);

switch (networkType) {

case 0:

break;

case 1:

NSLog(@"2G网络");

break;

case 2:

NSLog(@"3G网络");

break;

case 3:

NSLog(@"4G网络");

break;

case 5:

NSLog(@"wifi网络");

break;

default:

break;

}

}

}

实际上通过subViews数组还包括对应的网络提供商和时间以及电池的状态等，都可以从该数组中取到
