iOS 开发：判断网络权限授权弹窗并自动发起网络请求 (Objective-C 代码)

以下是一个示例的 Objective-C 代码，用于判断网络权限授权弹窗，并在用户授权后自动发起网络请求：

#import <UIKit/UIKit.h>
#import <Foundation/Foundation.h>
#import <SystemConfiguration/SystemConfiguration.h>
#import <netinet/in.h>

// 定义一个block来处理网络请求结果
typedef void (^NetworkRequestCompletion)(BOOL success, NSDictionary *response);

@interface ViewController : UIViewController

@property (nonatomic, copy) NetworkRequestCompletion completion;

@end

@implementation ViewController

- (void)viewDidLoad {
    [super viewDidLoad];
    
    // 请求网络权限授权
    [self requestNetworkPermission];
}

- (void)requestNetworkPermission {
    SCNetworkReachabilityRef reachabilityRef = SCNetworkReachabilityCreateWithName(NULL, 'www.apple.com');
    SCNetworkReachabilityFlags flags;
    BOOL success = SCNetworkReachabilityGetFlags(reachabilityRef, &flags);
    CFRelease(reachabilityRef);
    
    // 判断网络权限授权状态
    if ((flags & kSCNetworkReachabilityFlagsReachable) && !(flags & kSCNetworkReachabilityFlagsConnectionRequired)) {
        // 已授权，发起网络请求
        [self makeNetworkRequest];
    } else {
        // 未授权，弹窗提示用户开启网络权限
        UIAlertController *alert = [UIAlertController alertControllerWithTitle:'网络权限未授权' message:'请在设置中打开网络权限' preferredStyle:UIAlertControllerStyleAlert];
        UIAlertAction *okAction = [UIAlertAction actionWithTitle:'确定' style:UIAlertActionStyleDefault handler:^(UIAlertAction * _Nonnull action) {
            // 跳转到设置页面
            NSURL *url = [NSURL URLWithString:UIApplicationOpenSettingsURLString];
            if ([[UIApplication sharedApplication] canOpenURL:url]) {
                [[UIApplication sharedApplication] openURL:url options:@{} completionHandler:nil];
            }
        }];
        [alert addAction:okAction];
        [self presentViewController:alert animated:YES completion:nil];
    }
}

- (void)makeNetworkRequest {
    // 发起网络请求，这里仅做示例，可以根据实际需求来实现
    NSURL *url = [NSURL URLWithString:'https://api.example.com'];
    NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:url];
    [request setHTTPMethod:'GET'];
    
    NSURLSessionDataTask *task = [[NSURLSession sharedSession] dataTaskWithRequest:request completionHandler:^(NSData *data, NSURLResponse *response, NSError *error) {
        if (error) {
            self.completion(NO, nil);
        } else {
            NSDictionary *responseObject = [NSJSONSerialization JSONObjectWithData:data options:kNilOptions error:nil];
            self.completion(YES, responseObject);
        }
    }];
    
    [task resume];
}

@end

使用示例：

ViewController *viewController = [[ViewController alloc] init];
viewController.completion = ^(BOOL success, NSDictionary *response) {
    if (success) {
        NSLog('请求成功，response: %@', response);
    } else {
        NSLog('请求失败');
    }
};

[self presentViewController:viewController animated:YES completion:nil];

这是一个简单的示例，实际使用中可能需要根据具体的网络请求库或 API 进行相应的调整。
