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: Bool
public 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
