Question

我试图从Plist加载NSMutableDictionary。我的结果总是为NULL。

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>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>

我的代码非常简单：

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

有任何想法或帮助吗？感谢

你的plist不是NSDictionary，而是NSArray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，所以你需要启动一个数组：

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

然后循环遍历数组以获取各个字典，例如：

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

从plist加载NSMutableDictionary
