附件不會顯示在通過iPhone發送的郵件中

我已通過iPhone應用程序發送附件。附件不會顯示在通過iPhone發送的郵件中

但是，當我看到郵件時，我可以看到顯示附加內容的upin。

但是，當我打開郵件，我找不到任何附件？

這背後有什麼問題？

有沒有人遇到同樣的問題？

在此先感謝您分享您的寶貴知識。

的路徑是它支持的附件類型？ – bpapa 2009-12-04 17:46:58

是的！我見過很多應用程序使用這個擴展。 – 2009-12-04 17:48:18

你能顯示你用來發送的代碼嗎？如果您向郵件發送的郵件與郵件具有相同的附件，它會顯示出來嗎？ – 2009-12-04 17:57:52

這看起來錯，除非它只是用於測試：

// Attach an image to the email 
NSString *path = [[NSBundle mainBundle] pathForResource:@"myExport" ofType:@"csv"]; 
NSData *myData = [NSData dataWithContentsOfFile:path];

您使用的路徑是在您的應用程序包文件時，它是隻讀的，所以它不能成爲您剛剛製作的CSV文件。

，如果你想要寫一個臨時文件和電子郵件，你需要把它寫在某處喜歡你的文檔目錄，即像

NSArray *sysPaths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES); 
NSString *docDirectory = [sysPaths objectAtIndex:0]; 
NSString *filePath = [NSString stringWithFormat:@"%@/myexport.csv", docDirectory];
