iphone - 获取 NSDictionary 的字符串

Question

我有一个具有以下结构的plist:

<?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>height</key>
        <real>2075</real>
        <key>name</key>
        <string>Dublin-Pony-kids-25_thumb</string>
        <key>width</key>
        <real>1558</real>
    </dict>
    <dict>
        <key>height</key>
        <real>2219</real>
        <key>name</key>
        <string>Dublin-Pony-kids-26_thumb</string>
        <key>width</key>
        <real>1751</real>
    </dict>
    <dict>
        <key>height</key>
        <real>2532</real>
        <key>name</key>
        <string>Dublin-Pony-kids-27_thumb</string>
        <key>width</key>
        <real>1732</real>
    </dict>
    <dict>
        <key>height</key>
        <real>2430</real>
        <key>name</key>
        <string>Dublin-Pony-kids-28_thumb</string>
        <key>width</key>
        <real>1730</real>
    </dict>
</array>
</plist>

我想知道如何获取包含 key->name 的所有结果的 NSString。我想要像 Dublin-Pony-kids-25_thumb、Dublin-Pony-kids-26_thumb、Dublin-Pony-kids-27_thumb、Dublin-Pony-kids-28_thumb 这样的东西。

我可以像 (NSString *)imageNameAtIndex:(NSUInteger)index { 那样读取它但这只返回一个值。我希望 key->name 的所有值都为 NSString。

我对此很陌生，所以请帮忙。

如果将 plist 加载到数组中(通过 +[NSArray arrayWithContentsOfFile:...])，那么您应该能够执行以下操作:

NSArray *plistContents = [NSArray arrayWithContentsOfFile:...]; //load the plist into memory
NSArray *names = [plistContents valueForKey:@"name"];
