iOS开发：判断网络权限和Wi-Fi权限的OC代码示例

判断是否打开网络权限可以使用Reachability类来实现。首先，需要导入SystemConfiguration.framework框架，并引入Reachability.h头文件。

以下是一个示例代码：

#import <SystemConfiguration/SystemConfiguration.h>
#import <netinet/in.h>
#import <arpa/inet.h>
#import "Reachability.h"

// 判断是否打开网络权限
+ (BOOL)isNetworkEnabled {
    Reachability *reachability = [Reachability reachabilityForInternetConnection];
    NetworkStatus networkStatus = [reachability currentReachabilityStatus];
    
    return networkStatus != NotReachable;
}

// 判断Wi-Fi网络权限
+ (BOOL)isWiFiEnabled {
    Reachability *reachability = [Reachability reachabilityForLocalWiFi];
    NetworkStatus networkStatus = [reachability currentReachabilityStatus];
    
    return networkStatus == ReachableViaWiFi;
}

调用示例：

BOOL networkEnabled = [YourClassName isNetworkEnabled];
BOOL wifiEnabled = [YourClassName isWiFiEnabled];

if (networkEnabled) {
    NSLog('网络已打开');
} else {
    NSLog('网络未打开');
}

if (wifiEnabled) {
    NSLog('Wi-Fi已打开');
} else {
    NSLog('Wi-Fi未打开');
}

在使用前确保已经导入Reachability类文件，并添加SystemConfiguration.framework框架。
