ios - 如何从字典中读出数据？

Question

我有一个看起来像这样的 plist:

<dict>
<key>Aaron</key>
<dict>
    <key>number</key>
    <string>1234</string>
    <key>country</key>
    <string>Spanien</string>
    <key>year</key>
    <string>1989</string>
</dict>
<key>Abagail</key>
<dict>
    <key>number</key>
    <string>1234</string>
    <key>country</key>
    <string>Frankrike</string>
    <key>year</key>
    <string>2001</string>
</dict>
<key>Abbey</key>
<dict>
    <key>number</key>
    <string>1289</string>
    <key>country</key>
    <string>Tyskland</string>
    <key>year</key>
    <string>2009</string>
</dict>

通过这段代码，我得到了每个对象的键:

NSLog(@"test %@", [dict objectForKey:key2]);

如何获取每个对象的字符串值。我的 viewdidload 看起来像这样

NSString *path = [[NSBundle mainBundle] pathForResource:@"vin"
                                                 ofType:@"plist"];
NSDictionary *dict = [[NSDictionary alloc]initWithContentsOfFile:path];

self.allNames = dict;

NSString *key2 = viewTitle;

NSLog(@"test %@", [dict objectForKey:key2]);

Answer 1

基于上面的 plist，您可以访问 country 的值:

NSDictionary* record2 = (NSDictionary*)[dict objectForKey:key2];
NSString* country = (NSString*)[record2 objectForKey:@"country"];
