我需要注册我的应用。我将数据保存到mysql。我尝试了一些解决方案，但它不起作用。如果有任何解决方案请帮助我知道！我通过URL将数据保存到我的sql：
这是我的功能保存数据：
- (void)viewDidLoad {
[super viewDidLoad];
// Do any additional setup after loading the view from its nib.
UITapGestureRecognizer *oneTapGesture = [[UITapGestureRecognizer alloc]
initWithTarget: self
action: @selector(hideKeyboard:)];
[oneTapGesture setNumberOfTouchesRequired:1];
[[self view] addGestureRecognizer:oneTapGesture];
}
-
(IBAction)btnSave:(id)sender {
Pheptoan *functionStr = [[Pheptoan alloc] init];
NSInteger success=0;
@try{
if([[self.txtUsername text] isEqualToString:@""] || [[self.txtPassword text] isEqualToString:@""] || [[self.txtEmail text] isEqualToString:@""]
|| [[self.txtName text] isEqualToString:@""]|| [[self.txtTel text] isEqualToString:@""]){
[self showUIAlertWithMessage:@"User/Email not blank \n Password not blank" andTitle: @"Message"];
}else{
NSString *password = _txtPassword.text;
NSData *passwordData = [password dataUsingEncoding:NSUTF8StringEncoding];
NSString *passwordMD5 = [functionStr MD5:passwordData];
NSString *userUrl = [NSString stringWithFormat:@"http://ios.khothe.vn/web/gamecard/register/sUsername/%@/sPassword/%@/sName/%@/sEmail/%@/sTel/%@", _txtUsername.text, passwordMD5,_txtName.text,_txtEmail.text,_txtTel.text];
NSLog(@"link: %@", userUrl);
NSURL *url = [NSURL URLWithString:userUrl];
NSURLRequest *request=[NSURLRequest requestWithURL:url cachePolicy:NSURLRequestReloadIgnoringLocalAndRemoteCacheData timeoutInterval:30.0];
NSError *error = nil;
NSHTTPURLResponse *response;
NSData *data= [NSURLConnection sendSynchronousRequest:request returningResponse:&response error:&error];
if (!data) {
NSLog(@"Error: %@", [error localizedDescription]);
}
if([response statusCode]>=200 && [response statusCode]<300){
NSError *error= nil;
NSDictionary *jsonDictionary = [NSJSONSerialization JSONObjectWithData:data options:NSJSONReadingMutableContainers error:&error];
success = [[jsonDictionary valueForKey:@"success"] integerValue];
if(success == 400){
[self showUIAlertWithMessage:@"sucessfull" andTitle:@"Message"];
}else{
[self showUIAlertWithMessage:@"Error! Please wrong username or password" andTitle:@"Message"];
}
}
}
}@catch(NSException *e){
[self showUIAlertWithMessage:@"Error! Please login again" andTitle:@"Message"];
}
if(success == 400){
[self performSegueWithIdentifier:@"loginSuccess" sender:self];
}
}
这是我的函数在mysql中保存数据：
public function actionRegister()
{
$connection = Yii::app()->dbgamecard;
if($_GET != null){
$sUsername = $_GET["sUsername"];
$sPassword = $_GET["sPassword"];
$sName = $_GET["sName"];
$sEmail = $_GET["sEmail"];
$sTel = $_GET["sTel"];
$userInfo = Yii::app()->dbgamecard->createCommand("SELECT Username FROM member WHERE Username=:sUsername")
->bindParam(':sUsername', $sUsername)
->queryRow();
$arr = null;
if($userInfo){
echo json_encode(array("success" => 404));
//$arr["Status"] = "0";
//$arr["Message"] = "Username Exists!";
//echo json_encode($arr);
exit();
}
$userInfo = Yii::app()->dbgamecard->createCommand("SELECT Email FROM member WHERE Email=:sEmail")
->bindParam(':sEmail', $sEmail)
->queryRow();
if($userInfo){
echo json_encode(array("success" => 404));
//$arr["Status"] = "0";
//$arr["Message"] = "Email Exists!";
//echo json_encode($arr);
exit();
}
$strSQL = "INSERT INTO member (Username,Password,Name,Email,Tel)
VALUES(:strUsername, :strPassword, :strName, :strEmail, :strTel)";
$command= $connection->createCommand($strSQL);
$command->bindParam(":strUsername", $sUsername,PDO::PARAM_STR);
$command->bindParam(":strPassword", $sPassword,PDO::PARAM_STR);
$command->bindParam(":strName", $sName,PDO::PARAM_STR);
$command->bindParam(":strEmail", $sEmail,PDO::PARAM_STR);
$command->bindParam(":strTel", $sTel,PDO::PARAM_STR);
$command->execute();
if(!$command)
{
echo json_encode(array("success" => 404));
//$arr["Status"] = "0";
//$arr["Message"] = "Cannot Save Data!";
//echo json_encode($arr);
exit();
}
else{
$userInfo1['success'] = 400;
echo json_encode($userInfo);
//$arr["Status"] = "1";
//$arr["Message"] = "Register Successfully!";
//echo json_encode($arr);
exit();
}
}
mysql_close($objConnect);
}
}
我得错误

我不确定我的代码是好工作。但是如果有关于将数据保存到mysql的任何解决方案，请告诉我。我感谢所有的支持。谢谢你！
答案 0 :(得分：0)
错误是因为您调用了一个不存在的方法“hideKeyBoard”。
错误不属于保存数据的方法或什么。
