Link icon and social networks

Question

如何连接图标登录社交网络（即Facebook），登录后该图标将链接到Xcode中的个人资料图片？

Answer 1

Use the facebook API to login first. I am sure they all provide their logos to place into the app. Once you are logged in, try looking through API. If not, you can use a javascript command inside a UIWebView from logon information to link the UIIimage to the profile picture.
