ios登錄表格

Question

我從evernote網站下載了Iphone sdk.i的evernote示例應用程序，並將其與我的應用程序集成，我可以將說明保存到evernote並導入回來，但唯一的問題是登錄表單missing.the用戶名和密碼是靜態存儲在示例應用程序中。我不知道如何對此進行身份驗證以進行動態驗證。它使用單一設計。 in.h中

extern NSString * const username; 
extern NSString * const password; 

@interface evernoteloginpage : UIViewController { 

.M

NSString * const username = @"nips55"; 
NSString * const password = @"annyan555"; 
@implementation evernoteloginpage 

，但我需要它動態的，我有兩個textfiled和登錄按鈕，我需要的textfiled值添加到用戶名和password.i嘗試了很多但沒有運氣。如果有人知道如何爲Evernote添加登錄表單，請幫助我。 在此先感謝。 編輯 現在我成功登錄這個代碼的幫助，但問題是如果登錄成功，它將重定向到下一頁，如代碼所示，如​​果用戶輸入錯誤的用戶名或密碼，它的應用程序崩潰。如何處理這段代碼中的錯誤信息。

不幸的是，Eevernote API目前不包含iOS的任何代碼示例。如果您需要關於如何執行此操作的信息或示例，請查看本文。 http://digitalpericope.net/?p=27
