ASIFormDataRequest適用於模擬器，但不適用於設備？

Question

我正在使用ASIFormDataRequest發佈三個值，它們是url，標題和摘要。他們都在模擬器上正常工作，但它不能在設備上工作。這裏是我使用的代碼：

- (IBAction)addLinkPressed:(UIButton *)sender { 

    ASIFormDataRequest *loginRequest = [ASIFormDataRequest requestWithURL:[NSURL URLWithString:@"http://MyWebsite.com/login.php"]]; 
    [loginRequest setRequestMethod:@"POST"]; 
    [loginRequest setPostValue:[[NSUserDefaults standardUserDefaults] objectForKey:@"defaultUsername"] forKey:@"username"]; 
    [loginRequest setPostValue:[[NSUserDefaults standardUserDefaults] objectForKey:@"defaultPassword"] forKey:@"password"]; 
    [loginRequest setUseKeychainPersistence:YES]; 
    [loginRequest setDelegate:self]; 

    [loginRequest setDidFinishSelector:@selector(requestLoginFinished:)]; 
    [loginRequest setDidFailSelector:@selector(requestLoginFailed:)]; 
    [loginRequest startSynchronous]; 



    NSString *strURL = @"http://MyWebsite.com/send_link.php"; 
    ASIFormDataRequest *request = [ASIFormDataRequest requestWithURL:[NSURL URLWithString:strURL]]; 
    [request setDelegate:self]; 
    [request setPostValue:self.linkField.text forKey:@"url"]; 
    [request setPostValue:self.linkTitleField.text forKey:@"title"]; 
    [request setPostValue:self.linkSummaryField.text forKey:@"summary"]; 

    [request setDidFinishSelector:@selector(requestDone:)]; 
    [request setDidFailSelector:@selector(requestWentWrong:)]; 
    [request startAsynchronous]; 
} 

任何人都可以幫助我！

Answer 1

首先：ASIRequest不再支持。在某些情況下，它被稱爲是越野車，並且錯誤不會被修復。

第二個，關於你的問題，我看到那裏可能發生錯誤（模擬器和設備之間的差異）兩個地方：

1. 你肯定對設備[[NSUserDefaults standardUserDefaults] objectForKey:@"defaultUsername"]和[[NSUserDefaults standardUserDefaults] objectForKey:@"defaultPassword"]設置正確？

2. 在iOS模擬器上，您無法訪問鑰匙串，因此此設置（[loginRequest setUseKeychainPersistence:YES];）也可能導致設備出現問題。

我建議檢查NSUserDefaults，並更好地利用另外一個框架，即RestKit

編輯：使用RestKit的

例子：

[RKClient clientWithBaseURLString:@"http://example.com"]; 
RKClient *rkclient = [RKClient sharedClient]; 
RKParams *params = [RKParams paramsWithDictionary:[NSDictionary dictionaryWithObjectsAndKeys: 
                username, @"username", 
                password, @"password", nil]]; 
[rkclient post:@"/profile" params:params delegate:self]; 

// implement needed delegate methods
