異なるテキストフィールドに入力された値を目的のCのサーバーに保存する方法

Question

異なるテキストフィールドに入力された値を目的のCでサーバーに保存する方法私のプロジェクトでは、ユーザーがテキストフィールドに値を入力する必要がある別のテキストフィールドで構成されています。私は1つのSAVEボタンを保持しています。テキストフィールドに値を入力した後、ユーザーはSaveボタンをクリックします。

SAVEボタンをクリックすると、テキストフィールドに入力した値をサーバーに保存する必要があります。

SAVEボタンをクリックすると、データや値をサーバーに保存する方法を教えてください。あなたがコンパイルする必要が

#import "PopAppViewController.h" 
//#import "TimeSheetDatabase.h" 

@implementation PopAppViewController 

@synthesize popOverController,popOverControllerWithPicker,pickerViewController,txtTest,txtSun,txtMon,txtTue,txtWed,txtThurs,txtFri,txtSat,txtTotal,txtTask,txtProject;

の.mファイルで：

には、以下の.hファイルで、私は、フォームを作成するために使用したコード、

ですデータをJSON文字列に変換して、NSURLRequest

-(IBAction)save 
{ 
    // build JSON string 
    NSDictionary *postDictionary = [NSDictionary dictionaryWithObjectsAndKeys:self.txtTest.text, @"test", 
                      self.txtSun.text, @"sun", 
                      self.txtSun.text, @"mon", 
                      nil]; 
    NSData *postData = [NSJSONSerialization dataWithJSONObject:postDictionary options:NSJSONWritingPrettyPrinted error:NULL]; 

    // perform http request (on a background thread) 
    dispatch_queue_t queue = dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_DEFAULT, 0); 
    dispatch_async(queue, ^{ 
    NSAutoreleasePool *pool = [[NSAutoreleasePool alloc] init]; 

    NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:@"http://example.com/save.php" cachePolicy:NSURLRequestReloadIgnoringLocalCacheData timeoutInterval:60]; 
    [request setHTTPMethod:@"POST"]; 
    [request setHTTPBody:postData]; 

    NSHTTPURLResponse *urlResponse = nil; 
    NSError *error = NULL; 
    NSData *responseData = [NSURLConnection sendSynchronousRequest:request returningResponse:&urlResponse error:&error]; 

    // and now go back to the main thread 
    dispatch_async(dispatch_get_main_queue(), ^{ 
     NSAutoreleasePool *mainQueuePool = [[NSAutoreleasePool alloc] init]; 

     // debug: print response 
     NSLog(@"%@", [[NSString alloc] initWithData:responseData encoding:NSISOLatin1StringEncoding]); 

     // check for http error (this includes php exceptions) 
     if ([urlResponse statusCode] != 200) { 
     NSLog(@"save failed with status code != 200"); 
     return; 
     } 

     [mainQueuePool release]; 
    }); 

    [pool release]; 
    }); 
} 

そして、あなたのPHPで：

$rawData = file_get_contents("php://input"); 
$postData = json_decode($rawData); 

print_r($postData);
