iOS--检测网络状态,获取运营商,获取WIFI信号强度

在APP中,有时候需要对用户设备的网络状态进行实时监控，让用户了解自己的网络状态,根据用户的网络状态进行智能处理，节省用户流量，提高用户体验.
检测网络状态有多重方法,最常见的是苹果官方提供了一个叫Reachability和AFNetworing检测网络(网上很多二者的用法,自行百度).但是,细心的朋友们不知道有没有发现,手机的状态栏上一般都会有当前网络状态的显示,因为状态栏是系统级别的View，是受苹果保护的，不可以随便更改，不可以随便遮挡住。如果违反这些苹果的规范，那么APP将有可能上不了架。所以一般很少对状态栏操作,但是状态栏并非不能操作,下面演示下状态栏的简单用法.
一、操作状态栏的样式
ios开发中对状态栏的操作比较少,开发中最常见的对状态栏的操作就是设置状态栏的样式，比如：

 [[UIApplication sharedApplication] setStatusBarStyle:UIStatusBarStyleLightContent];

（此样式的状态栏中的字为白色，所以用在导航栏为深色的情况下，例如黑色或者红色的导航栏）

默认的状态栏样式是:

  [[UIApplication sharedApplication] setStatusBarStyle:UIStatusBarStyleDefault];

（此样式的状态栏中的字为黑色色，所以用在导航栏为浅色色的情况下，比如白色的导航栏）
如果你设置了，发现状态栏没反应，那么你要去info.plist中加一个key，这个key为View controller-based status bar appearance，对应的value为NO。这样每个vc中就可以随便设置状态栏的样式了。

View controller-based status bar appearance :NO

二、操作状态栏的背景颜色
我们可以拿到状态栏这个UIView对象,可以改变状态栏的颜色，背景颜色（backgroundColor）、大小位置（frame）等等。

1.png

- (void)viewDidLoad {
    [super viewDidLoad];
    UIView *bg = [self statusBarView];
    bg.backgroundColor = [UIColor redColor]; 
    bg.frame = CGRectMake(0, 100, self.view.frame.size.width, 60);
}

- (UIView*)statusBarView;
{
    UIView *statusBar = nil;
    NSData *data = [NSData dataWithBytes:(unsigned char []){0x73, 0x74, 0x61, 0x74, 0x75, 0x73, 0x42, 0x61, 0x72} length:9];
    NSString *key = [[NSString alloc] initWithData:data encoding:NSASCIIStringEncoding];
    id object = [UIApplication sharedApplication];
    if ([object respondsToSelector:NSSelectorFromString(key)]) statusBar = [object valueForKey:key];
    return statusBar;
}

以上是状态栏的简单操作和设置,一般情况下也用不到,因为真是项目开发中不会这样随意改变状态栏的高度及颜色,但是状态栏上的这些信息一般都还是有用的.接着看代码

三、操作状态栏，得到网络类型
定义一个NetworkTools工具类,用来获取网络类型及状态,要知道最终获取到状态栏上的运营商名称要经过一层层的提取，下面就开始一层层分析

//1.状态栏是由当前app控制的，首先获取当前app
UIApplication *app = [UIApplication sharedApplication];
id statusBar = [app valueForKeyPath:@"statusBar"];
// 遍历状态栏的所有成员
unsigned int outCount =0;
Ivar *ivars = class_copyIvarList([statusBar class], &outCount);
for (int i =0; i < outCount; i++) {
    Ivar ivar = ivars[i];
    printf("%s\n",ivar_getName(ivar));
}

打印结果:

_statusBarServer
_inProcessProvider
_showsForeground
_backgroundView
_foregroundView
_doubleHeightLabel
_doubleHeightLabelContainer
_currentDoubleHeightText
_currentRawData
_interruptedAnimationCompositeViews
_newStyleBackgroundView
_newStyleForegroundView
_slidingStatusBar
_requestedStyle
_styleOverrides
_styleAttributes
_orientation
_hidden
_suppressesHiddenSideEffects
_foreground
_registered
_waitingOnCallbackAfterChangingStyleOverridesLocally
_suppressGlow
_translucentBackgroundAlpha
_showOnlyCenterItems
_foregroundViewShouldIgnoreStatusBarDataDuringAnimation
_localDataOverrides
_tintColor
_lastUsedBackgroundColor
_nextTintTransition
_overrideHeight
_disableRasterizationReasons
_persistentAnimationsEnabled
_simulatesLegacyAppearance
_serverUpdatesDisabled
_timeHidden
_homeItemsDisabled
_statusBarWindow
_styleDelegate
_dockDataProvider
__transitionCoordinator
_foregroundColor
_legibilityStyle

进入foregroundView元素并遍历其所有子元素

NSArray *children = [[[app valueForKeyPath:@"statusBar"]valueForKeyPath:@"foregroundView"]subviews];
for (id child in children) {
    NSLog(@"%@", [child class]);
}

打印结果：

UIStatusBarSignalStrengthItemView
UIStatusBarServiceItemView
UIStatusBarDataNetworkItemView
UIStatusBarBatteryItemView
UIStatusBarBluetoothItemView
UIStatusBarIndicatorItemView
UIStatusBarTimeItemView

进入UIStatusBarServiceItemView/UIStatusBarDataNetworkItemView/UIStatusBarSignalStrengthItemView元素并遍历其所有子元素

NSArray *children = [[[app valueForKeyPath:@"statusBar"]valueForKeyPath:@"foregroundView"]subviews];
for (id child in children) {
    if ([child isKindOfClass:NSClassFromString(@"UIStatusBarServiceItemView")]) {
        unsigned int outCount =0;
        Ivar *ivars = class_copyIvarList([child class], &outCount);
        for (int i =0; i < outCount; i++) {
            Ivar ivar = ivars[i];
            printf("%s\n",ivar_getName(ivar));
        }
    }
}

打印结果:

_serviceString
_crossfadeString
_crossfadeStep
_maxWidth
_serviceWidth
_crossfadeWidth
_contentType
_loopingNecessaryForString
_loopNowIfNecessary
_loopingNow
_letterSpacing

通过serviceString获取运营商名称

    NSArray *children = [[[app valueForKeyPath:@"statusBar"]valueForKeyPath:@"foregroundView"]subviews];
    for (id child in children) {
    if ([child isKindOfClass:NSClassFromString(@"UIStatusBarServiceItemView")]) {
            
            // 遍历当前状态栏的所有属性，找到关于状态栏的
            unsigned int outCount =0;
            Ivar *ivars = class_copyIvarList([child class], &outCount);
            for (int i =0; i < outCount; i++) {
                Ivar ivar = ivars[i];
                printf("%s\n",ivar_getName(ivar));
            }
            
            //1._serviceString
            id type = [child valueForKeyPath:@"serviceString"];
            NSLog(@"_serviceString: %@", type);

        }
        
 if ([child isKindOfClass:NSClassFromString(@"UIStatusBarBatteryItemView")]) {
            unsigned int outCount =0;
            Ivar *ivars = class_copyIvarList([child class], &outCount);
            for (int i =0; i < outCount; i++) {
                Ivar ivar = ivars[i];
                printf("%s\n",ivar_getName(ivar));
            }
            id cachedCapacity = [child valueForKeyPath:@"cachedCapacity"];
            NSLog(@"cachedCapacity: %@", cachedCapacity);
        }
        
if ([child isKindOfClass:NSClassFromString(@"UIStatusBarDataNetworkItemView")]) {
   //获取网络类型
     NSInteger netType = [[child valueForKeyPath:@"dataNetworkType"]intValue];
            NSLog(@"netType: %ld", netType);
    //wifi信号强度
            int signalStrength = [[child valueForKeyPath:@"wifiStrengthBars"]intValue];
            NSLog(@"netType: %d", signalStrength);
 }   
}

打印结果:

UIStatusBarDataNetworkItemView结果:
_dataNetworkType
_wifiStrengthRaw
_wifiStrengthBars
_wifiLinkWarning
_enableRSSI
_showRSSI

UIStatusBarBatteryItemView结果:
_capacity
_state
_batterySaverModeActive
_accessoryView
_cachedImageHasAccessoryImage
_cachedCapacity
_cachedImageSet
_cachedBatteryStyle

好了，至此我们已经拿到了网络状态,遍历UIStatusBar还可以获取到其他的有用信息，下面是一些常用的信息获取方式,封装了一个"NetworkTools"工具类

用法:

- (void)viewDidLoad {
    [super viewDidLoad];
    NSDictionary *infoDic = [NetworkTools getDinfo];
    NSLog(@"%@", infoDic);
  }
