从 plist 加载 NSMutableDictionary

Question

我正在尝试从 Plist 加载 NSMutableDictionary。我的结果总是 NULL。

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>LocNum</key>
            <string>0</string>
            <key>LocName</key>
            <string>Head</string>
        </dict>
        <dict>
            <key>LocNum</key>
            <string>1</string>
            <key>LocName</key>
            <string>Left Hand</string>
        </dict>
        <dict>
            <key>LocNum</key>
            <string>2</string>
            <key>LocName</key>
            <string>Right Hand</string>
        </dict>
       ....
    </array>
</plist>

我的代码很简单：

locDictionary = [[NSMutableDictionary alloc] init];
NSString *locListpath = [[NSBundle mainBundle] pathForResource:@"LocList" ofType:@"plist"];
locDictionary = [NSMutableDictionary dictionaryWithContentsOfFile:locListpath];
NSLog(@"locDictionary %@", locDictionary);

有什么想法或帮助吗？谢谢

Answer 1

你的 plist 不是 NSDictionary，而是 NSArray 的字典，如果它放在磁盘上的适当位置那么这段代码应该有帮助：

NSString *path = [[NSBundle mainBundle] pathForResource:@"LocList" ofType:@"plist"];
NSMutableArray *locArray = [[NSMutableArray alloc] initWithContentsOfFile:path];

Answer 2

你的plist定义了一个字典数组，而不是字典本身，所以你需要初始化一个数组：

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

然后遍历数组以获取单个字典，例如：

for (NSDictionary *dict in array) {
...
}
