MessageUI(发送短信)

在MessageUI库中发送短信使用MFMessageComposeViewController。

1 相关API

1.1 Determining If Message Composition Is Available

/// 能否发短信////// - returns: Boolpublic class func canSendText() -> Bool/// 能否发主题////// - returns: Bool@available(iOS 7.0, *)public class func canSendSubject() -> Bool/// 能否发附件////// - returns: Bool@available(iOS 7.0, *)public class func canSendAttachments() -> Bool/// 附件的UTI支持////// - parameter uti :  See [Uniform Type Identifiers Reference](https://developer.apple.com/library/ios/documentation/Miscellaneous/Reference/UTIRef/Introduction/Introduction.html)////// - returns: Bool@available(iOS 7.0, *)public class func isSupportedAttachmentUTI(uti: String) -> Bool

1.2 Accessing the Delegate

/// 监听发送结果unowned(unsafe) public var messageComposeDelegate: MFMessageComposeViewControllerDelegate?

1.3 Setting the Initial Message Information

/// 取消添加附件的按钮@available(iOS 7.0, *)public func disableUserAttachments()/// 收件人public var recipients: [String]?/// 内容public var body: String?/// 主题public var subject: String?/// 所有附件public var attachments: [[NSObject : AnyObject]]? { get }/// 添加url类型的附件@available(iOS 7.0, *)public func addAttachmentURL(attachmentURL: NSURL, withAlternateFilename alternateFilename: String?) -> Bool/// 添加NSData数据的附件@available(iOS 7.0, *)public func addAttachmentData(attachmentData: NSData, typeIdentifier uti: String, filename: String) -> Bool
