Question

我正在尝试同时将Facebook和Twitter身份验证添加到我的本机应用程序中。

根据官方说明，我需要以下列方式修改针对handUrl的AppDelegate.m文件：

- (BOOL)application:(UIApplication *)app openURL:(NSURL *)url options:(NSDictionary<NSString *,id> *)options {
  return [[Twitter sharedInstance] application:app openURL:url options:options];
}

以及Facebook的以下方式。

- (BOOL)application:(UIApplication *)application 
            openURL:(NSURL *)url 
            options:(NSDictionary<UIApplicationOpenURLOptionsKey,id> *)options {

  BOOL handled = [[FBSDKApplicationDelegate sharedInstance] application:application
    openURL:url
    sourceApplication:options[UIApplicationOpenURLOptionsSourceApplicationKey]
    annotation:options[UIApplicationOpenURLOptionsAnnotationKey]
  ];
  // Add any custom logic here.
  return handled;
}

我如何将两者结合起来？我试图检查变量并决定返回哪个但是到目前为止没有成功。

您可以尝试检查 url.absoluteString

例如：

- (BOOL)application:(UIApplication *)application openURL:(NSURL *)url sourceApplication:(NSString *)sourceApplication annotation:(id)annotation {

  //Get absolute string
  NSString *aStrURL = url.absoluteString;

  if ([aStrURL containsString:@"YOUR_FACEBOOK_APP_ID"]){
    // facebook related code here
    return [[FBSDKApplicationDelegate sharedInstance] application:application
                                                          openURL:url
                                                sourceApplication:sourceApplication
                                                       annotation:annotation];

  }
  else{
    // twitter or other code here
    return [[Twitter sharedInstance] application:app openURL:url options:options];
  }
}

您可以像这样检查url.scheme： -

- (BOOL)application:(UIApplication *)application openURL:(NSURL *)url 
sourceApplication:(NSString *)sourceApplication annotation:(id)annotation {

  //App opened with Facebook scheme
  if([url.scheme isEqualToString:@"YOUR_FACEBOOK_ID"]){
       return [[FBSDKApplicationDelegate sharedInstance] application:app
                                                           openURL:url
                                                    sourceApplication:options[UIApplicationOpenURLOptionsSourceApplicationKey]
                                                           annotation:options[UIApplicationOpenURLOptionsAnnotationKey]];
  }
  //App opened with Twitter scheme
  else if ([url.scheme isEqualToString:@"YOUR_TWITTER_ID"]){
       return [[Twitter sharedInstance] application:app openURL:url options:options];
  }
  //App opened with different scheme
  else{
      return YES;
  }
}

我最终通过以下方式解决问题：

我的AppDelegate.m

#import "AppDelegate.h"

#import <React/RCTBundleURLProvider.h>
#import <React/RCTRootView.h>
#import <TwitterKit/TwitterKit.h>
#import <FBSDKCoreKit/FBSDKCoreKit.h>
#import <FBSDKLoginKit/FBSDKLoginKit.h>

@implementation AppDelegate

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
  NSURL *jsCodeLocation;

  jsCodeLocation = [[RCTBundleURLProvider sharedSettings] jsBundleURLForBundleRoot:@"index" fallbackResource:nil];

  RCTRootView *rootView = [[RCTRootView alloc] initWithBundleURL:jsCodeLocation
                                                      moduleName:@"mirrorapp"
                                               initialProperties:nil
                                                   launchOptions:launchOptions];
  rootView.backgroundColor = [[UIColor alloc] initWithRed:1.0f green:1.0f blue:1.0f alpha:1];

  self.window = [[UIWindow alloc] initWithFrame:[UIScreen mainScreen].bounds];
  UIViewController *rootViewController = [UIViewController new];
  rootViewController.view = rootView;
  self.window.rootViewController = rootViewController;
  [self.window makeKeyAndVisible];
  return [[FBSDKApplicationDelegate sharedInstance] application:application
                                  didFinishLaunchingWithOptions:launchOptions];
//  return YES;
}

- (BOOL)application:(UIApplication *)app openURL:(NSURL *)url options:(NSDictionary<NSString *,id> *)options {
  return [[Twitter sharedInstance] application:app openURL:url options:options];
}

- (BOOL)application:(UIApplication *)application openURL:(NSURL *)url sourceApplication:(NSString *)sourceApplication annotation:(id)annotation {
  return [[FBSDKApplicationDelegate sharedInstance] application:application
                                                        openURL:url
                                              sourceApplication:sourceApplication
                                                     annotation:annotation];
}
