ios - 遍历iOS中plist的字典数组

Question

我是 iOS 编程的新手，我正在研究遍历 plist。但是我无法访问标签中的单个记录。也就是说，如果我只想访问“Amul”的详细信息，那么在 if 条件中应该写些什么

下面是我的plist文件

<?xml version="1.0" encoding="UTF-8"?>
 <!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN"     
"http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
<array>
<dict>
    <key>Email Address</key>
    <string>ams@asd.com</string>
    <key>Name</key>
    <string>Amul</string>
    <key>Phone Number</key>
    <string>984756393</string>
</dict>
<dict>
    <key>Email Address</key>
    <string>cat@se.com</string>
    <key>Name</key>
    <string>Anoop</string>
    <key>Phone Number</key>
    <string>87453726</string>
</dict>
<dict>
    <key>Email Address</key>
    <string>per@se.com</string>
    <key>Name</key>
    <string>Bhagesss</string>
    <key>Phone Number</key>
    <string>7684947</string>
</dict>
</array>
</plist>

我也在读取数组中的所有数据，如下所示

NSArray *array=[[NSArray alloc]initWithContentsOfFile:filePath];


    if (i<[array count]) {
        NSLog(@"%@", [array objectAtIndex:i]);
        NSString *strName=[[NSString alloc]initWithFormat:@"%@",[array 
  valueForKey:@"Name"]];
        NSString *strPhone=[[NSString alloc]initWithFormat:@"%@",[array 
  valueForKey:@"Phone Number"]];
        NSString *strEmail=[[NSString alloc]initWithFormat:@"%@",[array 
  valueForKey:@"Email Address"]];

        lblName.text=strName;
        lblPhone.text=strPhone;
        lblEmail.text=strEmail;

        i++;
}

现在我应该提出什么条件，以便只显示我在文本字段中提供的名称的记录。请帮助...

在 NSString 上使用 isEqualToString 方法。顺便说一句，NSArray 中没有 valueForKey 方法!正如前面建议的答案，使用字典。这是完整的代码。

NSArray *array=[[NSArray alloc]initWithContentsOfFile:filePath];

int i = 0;
while (i<[array count]) {

    NSDictionary *dict = [array objectAtIndex:i];

    if([[dict objectForKey:@"Name"] isEqualToString:@"Amul"])
    {
        lblName.text=strName;
        lblPhone.text=strPhone;
        lblEmail.text=strEmail;
        break;
    }
    i++;
}
