我在视图上有一些按钮。我不知道有多少,我知道它可以是最小值2或最多4个。我想检查每个按钮的标题文本并根据标题值添加到数组true或false。

有可能吗?

是的,可以遍历视图中的所有对象。要查看视图中显示的所有子视图,您可以执行以下操作:

<?php
    if(isset($_POST['submit']))
    {
        $id=$_SESSION['id'];
        //$date1=date("Y-m-d");
        //echo $date1;
        $work=$_POST['postinput0'];
        //echo $work;
        $project_name=$_POST['postinput1'];
        $skills=$_POST['postinput2'];
        $description=$_POST['postinput3'];
        $file1=$_POST['file1'];
        $budget=$_POST['postinput4'];
        //$radio=$_POST['radio'];
        $sql = "INSERT INTO Job_post (u_id,job_category,project_name,job_sub_category,project_description,image,budget) VALUES('$id','$work','$project_name','$skills', '$description','$file1','$budget')";
        $query = mysql_query( $sql, $conn );
        if(isset($query))
        {
            echo "successfully";
        }
        else
        {
            echo "not successfully inserted";
        }
    }
?>

尝试下面的事情..

    for view in self.view.subviews {
        if view.isKindOfClass(UIButton){
            // Add you logic over here. 
            // you can check the tag of button as well.
        }
    }
