从plist加载NSMutableDictionary

Question

我正在尝试从Plist加载NSMutableDictionary。 我的结果始终为NULL。

列表

<?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

您的plist不是NSDictionary ，而是NSArray字典，如果将其放置在磁盘上的适当位置，则此代码应有帮助：

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

Answer 2

您的plist定义了一个字典数组，而不是字典本身，因此您需要启动一个数组：

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

然后遍历数组以得到类似以下内容的单个字典：

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