Question

我一直在努力让facebook登录按钮工作一段时间。我试图四处搜索并尝试了其他人的几种解决方案，但仍然无法解决问题。

问题是Facebook登录按钮显示为空红色边框框。

我按照facebook网站上的所有说明以及react-native-fbsdk github文档但仍然没有运气。

我想出了问题，我在AppDelegate.m中实现代码的方法出了什么问题

应该看起来像这样

#import <React/RCTRootView.h>

// Facebook SDK Installation
#import <FBSDKCoreKit/FBSDKCoreKit.h>
#import <FBSDKLoginKit/FBSDKLoginKit.h>

@implementation AppDelegate

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

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

  RCTRootView *rootView = [[RCTRootView alloc] initWithBundleURL:jsCodeLocation
                                                      moduleName:@"fongdue"
                                               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];

  return YES;
}

- (void)applicationDidBecomeActive:(UIApplication *)application {
  [FBSDKAppEvents activateApp];
}

- (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;
}

@end

现在按钮显示并按预期工作

React-native FacebookSDK显示为带有红色边框的空框
