如何編寫XML文件中的iPhone

Question

我需要我的用戶名和密碼存儲到一個XML文件中的格式

<user>abcde</user> 
    <pass>123355</pass> 

我怎麼能寫這個文件，這樣就可以輕鬆地閱讀它的文檔目錄？

正如@Mike ..建議的那樣，您應該使用鑰匙串來存儲密碼..谷歌它..有在線教程。

至於xml存儲。 下面是代碼

 NSData *serializedData; 
     NSString *error; 
     serializedData = [NSPropertyListSerialization dataFromPropertyList:YourArray(You can use dictionaries.strings..and others too) 
     format:NSPropertyListXMLFormat_v1_0 errorDescription:&error]; 
     if (serializedData) { 
     // Serialization was successful, write the data to the file system // Get an array of paths. 

     NSArray *documentDirectoryPath = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES); 
     NSString *docDir = [NSString stringWithFormat:@」%@/serialized.xml」, 
     [documentDirectoryPath objectAtIndex:0]]; 
     [serializedData writeToFile:docDir atomically:YES]; 
} 
     else { 
     // An error has occurred, log it 
     NSLog(@」Error: %@」,error); } 
     }
