將PDF文件附加到電子郵件中 ​​- Swift

Question

我想用PDF附件發送電子郵件。 我創建的PDF文件，然後我這是錯誤的下面筆者認爲：

// locate folder containing pdf file    
let documentsPath = NSSearchPathForDirectoriesInDomains(NSSearchPathDirectory.DocumentDirectory, NSSearchPathDomainMask.UserDomainMask, true)[0] as! String 

let pdfFileName = documentsPath.stringByAppendingPathComponent("chart.pdf") 
let fileData = NSData(contentsOfFile: pdfFileName) 
mc.addAttachmentData(fileData, mimeType: "pdf", fileName: chart) 

前發送電子郵件，我可以看到連接chart.pdf，但是當我發送的電子郵件，這是沒有附件發送，這是因爲我沒有正確附加文件。
