我有这个奇怪的问题,由于某种原因我的segue无法正常工作.

我有两个segues设置,取决于一个设置的状态确定它选择的segue.其中一个像魅力一样,而另一个得到"接收器没有带标识符的segue"

- (void)viewDidLoad
{
[super viewDidLoad];
// Do any additional setup after loading the view, typically from a nib.

// check if registered already
if ([[NSUserDefaults standardUserDefaults] boolForKey:@"registered"] == YES) {
    // Registered

    // Give the logo some time to show before moving on
    [NSTimer scheduledTimerWithTimeInterval:4.0 target:self selector:@selector(splashLoadedRegistered:) userInfo:nil repeats:NO];
} else {
    // Register

    // Give the logo some time to show before moving on
    [NSTimer scheduledTimerWithTimeInterval:4.0 target:self selector:@selector(splashLoaded:) userInfo:nil repeats:NO];
}
}



-(void)splashLoaded:(id)sender
{
//This one works …

我遇到一个问题，第一次单击“提交”并重新加载页面后，页面会显示每个 cookie 设置的旧值，直到刷新或重新加载页面为止。

这基本上就是我的设置方式。

索引.php

<?php 
    if(isset($_POST['filter'])){
        foreach($_POST['filter'] as $key=>$value){
            $xNums[] = $key;    
        }
        $vals = $_POST['filter'];
        updateFilter($vals, $xNums);
    }
?>
<form action='index.php' method='post'>
<input type='radio' name=filter['".$xNum."'] value='yes' />Show<input type='radio' name=filter['".$SomeVariable."'] value='no' />Hide
<input type=submit value=" Submit " />
<?php
    echo displayStatus($xNum);
?>

函数.php

function updateFilter($vals, $xNums){
    foreach($xNums as $xNum){
        $val = $vals[$xNum];
        setcookie($xNum, $val, time()+3600);
    }
    return;
}

function displayStatus($xNum){
    if($_COOKIE["'".$xNum."'"]=='no'){
        return "no";
    } else {
        return "yes";
    }
}
