如何创建多个问题？ [英] How to Create a Multiple Question?

问题描述

我需要从plist检索6个问题，并从plist本身检查答案是否正确

我将使用QR码扫描器api扫描为了回答，api将隐藏到一个字符串并从plist读取，以检查如果答案是否正确...是否有任何教程或引用我看看@ ??

在我的plist中有：
question〜具有以下字符串的字典：

NumberOfOption〜定义如果问题是多项选择或QR代码问题
问题〜问题本身
答案〜答案本身
选项1〜4〜如果它是多项选择问题

非常感谢。

干杯

使用以下代码读取数据到字典数组中（假设您的plist在您的主包中）

  // plist的路径（在应用程序包中）
 NSString * path = [[NSBundle mainBundle] pathForResource：
 @questionArrayofType： @plist]; 
 
 //从plist构建数组
 NSMutableArray * qArray = [[NSMutableArray alloc] initWithContentsOfFile：path]; 
  

您可以重复以下问题：

  //迭代问题
 for（NSDictionary * dic in qArray）
 {
 //从dic对象读取'NumberOfOption'这里。 
} 
  

I need to retrieve 6 questions from a plist and check the answer if is correct from the plist itself??

i will use a QR code scanner api to scan for answer, the api will covert to a string and read from the plist to check if the answer is correct... is there any tutorial or references for me to look @ ??

In my plist there is: question ~ Dictionary with the following strings:

NumberOfOption ~ which define if the question is a multiple choice or a QR code question Question ~ question itself Answer ~ Answer itself Option 1 ~ 4 ~ if it is a multiple choice question

Thanks in advance for answering my questions, i appreciated it

cheers

解决方案

Use the following code to read data into a array of Dictionaries (assuming your plist is in your main bundle)

// Path to the plist (in the application bundle)
NSString *path = [[NSBundle mainBundle] pathForResource:
    @"questionArray" ofType:@"plist"];

// Build the array from the plist  
NSMutableArray *qArray = [[NSMutableArray alloc] initWithContentsOfFile:path];

you can then iterate over your questions like:

// iterate questions
for (NSDictionary *dic in qArray)
{
    //perform your reading of 'NumberOfOption' etc from dic object here. 
}
