iOS 接入Twitter 相关注意点

1. 接入前配置

• Download and unzip Twitter Kit
• Add TwitterKit to "Embedded Binaries" in your Xcode project settings(测试发现不添加也可以)
• Add TwitterKit and TwitterCore to "Linked Frameworks and Libraries" in your Xcode project settings
• Add SafariServices.framework to use SFSafariViewController
• In your app's Info.plist, add URL Schemes by adding code below after

<key>CFBundleURLTypes</key>
<array>
  <dict>
    <key>CFBundleURLSchemes</key>
    <array>
      <string>twitterkit-<consumerKey></string>
    </array>
  </dict>
</array>
<key>LSApplicationQueriesSchemes</key>
<array>
    <string>twitter</string>
    <string>twitterauth</string>
</array>

• Make sure to import the framework header: #import <TwitterKit/TWTRKit.h>

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
    [[Twitter sharedInstance] startWithConsumerKey:@"hTpkPVU4pThkM0" consumerSecret:@"ovEqziMzLpUOF163Qg2mj"];
}

• Implement the application:openURL:options method in your Application Delegate, and pass along the redirect URL to Twitter Kit

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

2. Twitter后台配置 https://apps.twitter.com/app

Twitter apps dashboard
From June 12th 2018 callback locking will no longer be optional. The correct callback format for iOS apps is:twitterkit-MY_CONSUMER_KEY://
