在iPhone X 上通过状态栏获取联网状态使用下面的代码直接闪退
- (BOOL)networkingStatesFromStatebar {UIApplication *app = [UIApplication sharedApplication];NSArray *children = nil;children = [[[app valueForKeyPath:@"statusBar"] valueForKeyPath:@"foregroundView"] subviews];int type = 0;for (id child in children) {if ([child isKindOfClass:[NSClassFromString(@"UIStatusBarDataNetworkItemView") class]]) {type = [[child valueForKeyPath:@"dataNetworkType"] intValue];}}if (type == 0) {return NO;}else{return YES;}}
网上其他的方法
children = [[[app valueForKeyPath:@"statusBar"] valueForKeyPath:@"statusBar"] valueForKeyPath:@"foregroundView"] subviews];
不崩溃，但是不能获取正确的状态。
因此打印一下，看看能发现什么
UIApplication *app = [UIApplication sharedApplication] ;id _statusBar = [app valueForKeyPath:@"_statusBar"];//UIStatusBar_Modernid _statusBar2 = [_statusBar valueForKeyPath:@"_statusBar"];
打印_statusBar2得到

发现了几个关于蜂窝数据与wifi的item
_UIStatusBarCellularItem
_UIStatusBarWifiItem
然后看看如何获取这些Items。
通过xcode设置断点直接查看，得到items里面没有什么可用信息，但是在_displayItemStates有
打印_displayItemStates得到
里面包括状态栏的所有元素,打印一个
_dataEnabled就是数据可用的状态
下面就是判断的代码，
- (BOOL)networkingStatesFromStatebar {if(IsIphoneX){//适配iPhoneXUIApplication *app = [UIApplication sharedApplication] ;NSDictionary *_displayItemStates = [[[app valueForKeyPath:@"_statusBar"] valueForKeyPath:@"_statusBar"] valueForKeyPath:@"_displayItemStates"];////wifi//id value = _displayItemStates[@"_UIStatusBarWifiItem.signalStrengthDisplayIdentifier"];NSLog(@"%@",[value class]);//_UIStatusBarDisplayItemStatebool _dataEnabled =[[value valueForKeyPath:@"_dataEnabled"]boolValue];if (_dataEnabled == YES) {return YES;}////移动数据//value = _displayItemStates[@"_UIStatusBarCellularItem.typeDisplayIdentifier"];bool _dataEnabledCell =[[value valueForKeyPath:@"_dataEnabled"]boolValue];if (_dataEnabledCell == YES) {return YES;}return NO;}else{UIApplication *app = [UIApplication sharedApplication];NSArray *children = nil;children = [[[app valueForKeyPath:@"statusBar"] valueForKeyPath:@"foregroundView"] subviews];int type = 0;for (id child in children) {if ([child isKindOfClass:[NSClassFromString(@"UIStatusBarDataNetworkItemView") class]]) {type = [[child valueForKeyPath:@"dataNetworkType"] intValue];}}if (type == 0) {return NO;}else{return YES;}}
iOS12的状态栏结构有变化需要更改一下（0818更新）：
- (BOOL)networkingStatesFromStatebar {if(IsIphoneX){//适配iPhoneXUIApplication *app = [UIApplication sharedApplication] ;NSDictionary *_displayItemStates = [[[app valueForKeyPath:@"_statusBar"] valueForKeyPath:@"_statusBar"] valueForKeyPath:@"_displayItemStates"];////wifi//id value = _displayItemStates[@"_UIStatusBarWifiItem.signalStrengthDisplayIdentifier"];NSLog(@"%@",[value class]);//_UIStatusBarDisplayItemStatebool _dataEnabled =[[value valueForKeyPath:@"_dataEnabled"]boolValue];if (IOS12_OR_LATER) {for (id ieentifi in _displayItemStates.allKeys) {NSString *identifier = [NSString stringWithFormat:@"%@",ieentifi];if ([identifier isEqualToString:@"_UIStatusBarWifiItem.signalStrengthDisplayIdentifier"]) {value = _displayItemStates[ieentifi];_dataEnabled =[[value valueForKeyPath:@"_dataEnabled"]boolValue];}}}if (_dataEnabled == YES) {return YES;}////移动数据//value = _displayItemStates[@"_UIStatusBarCellularItem.typeDisplayIdentifier"];bool _dataEnabledCell =[[value valueForKeyPath:@"_dataEnabled"]boolValue];if (IOS12_OR_LATER) {bool _dataEnabledCell111111 = false;bool _dataEnabledCell222222 = false;for (id ieentifi in _displayItemStates.allKeys) {NSString *identifier = [NSString stringWithFormat:@"%@",ieentifi];//if ([identifier isEqualToString:@"_UIStatusBarCellularCondensedItem.typeDisplayIdentifier"]) {value = _displayItemStates[ieentifi];_dataEnabledCell111111 =[[value valueForKeyPath:@"_dataEnabled"]boolValue];}if ([identifier isEqualToString:@"_UIStatusBarSecondaryCellularExpandedItem.typeDisplayIdentifier"]) {value = _displayItemStates[ieentifi];_dataEnabledCell222222 =[[value valueForKeyPath:@"_dataEnabled"]boolValue];}}_dataEnabledCell = _dataEnabledCell111111 || _dataEnabledCell222222;}if (_dataEnabledCell == YES) {return YES;}return NO;}else{NSLog(@"%@",GlobalVariablesSingle.name);NSLog(@"%d",[[[UIDevice currentDevice] systemVersion] intValue]);//ios12测试版系统崩溃ipadpro 只要ios12的ipad系统都不判断if (([GlobalVariablesSingle.name rangeOfString:@"iPad"].length > 0)&& [[[UIDevice currentDevice] systemVersion] intValue] == 12) {return YES;}UIApplication *app = [UIApplication sharedApplication];NSArray *children = nil;children = [[[app valueForKeyPath:@"statusBar"] valueForKeyPath:@"foregroundView"] subviews];int type = 0;for (id child in children) {if ([child isKindOfClass:[NSClassFromString(@"UIStatusBarDataNetworkItemView") class]]) {type = [[child valueForKeyPath:@"dataNetworkType"] intValue];}}if (type == 0) {return NO;}else{return YES;}}}
