Question

我正在尝试通过短信，EMAIL将iPhone的GPSLocation坐标发送到收件人列表，并将其发布到Facebook并在Twitter上发送推文，点击一下按钮。（我收到了收件人邮件和电话号码从其他标签视图列表）

但无论我尝试过什么，我都无法按顺序发送邮件，消息，推文和Facebook发送视图。

请帮助我，我们将不胜感激。

我正在使用 Xcode 5 和 iOS 7 进行开发。

我收到了这些消息（我猜现在null是因为模拟器无法模拟发送短信，对于其他消息我不知道其背后的原因）

您应该在完成委托回调中显示新的视图控制器。也就是说，例如，当您的推特代表告诉您已发送推文时，呈现邮件视图控制器，当它的代表告诉您完成时，呈现Facebook视图控制器，等等（按顺序）你想要的。）
