读出Plist问题

Question

为什么 naam 输出（NULL）？ （抱歉，我知道这是基本的东西，但我是 plist 新手）

这是 plist：

方法如下：

- (id) init {

self = [super init];
if (self) {
    NSString *errorDesc = nil;
    NSPropertyListFormat format;
    NSString *plistPath;
    NSString *rootPath = [NSSearchPathForDirectoriesInDomains(NSDocumentDirectory,
                                                              NSUserDomainMask, YES) objectAtIndex:0];
    plistPath = [rootPath stringByAppendingPathComponent:@"Data.plist"];
    NSLog(@"path: %@",plistPath);
    if (![[NSFileManager defaultManager] fileExistsAtPath:plistPath]) {
        plistPath = [[NSBundle mainBundle] pathForResource:@"Data" ofType:@"plist"];
    }
    NSData *plistXML = [[NSFileManager defaultManager] contentsAtPath:plistPath];

    NSDictionary *temp = (NSDictionary *)[NSPropertyListSerialization
                                          propertyListFromData:plistXML
                                          mutabilityOption:NSPropertyListMutableContainersAndLeaves
                                          format:&format
                                          errorDescription:&errorDesc];
      NSLog(@"temp: %@",temp);
    if (!temp) {
        NSLog(@"Error reading plist: %@, format: %d", errorDesc, format);
    }
    self.personName = [temp objectForKey:@"Name"];
    NSLog(@"NAAM:%@",[temp objectForKey:@"Name"]);
    self.phoneNumbers = [NSMutableArray arrayWithArray:[temp objectForKey:@"Phones"]];


}
return self;}

Answer 1

因为temp是一个字典，只包含一个键：@“Root”。您正在内部字典中查找对象：[[temp objectForKey:@"Root"] objectForKey:@"Name"]

Answer 2

先尝试解压ROOT。

NSDictionary* root=[temp objectForKey:@"Root"];
NSLog(@"NAAM:%@",[root objectForKey:@"Name"]);

Answer 3

尝试

NSLog(@"NAAM: %@", [temp valueForKeyPath:@"Root.Name"]);

从 Phones 启动第一部手机，执行以下操作：

NSDictionary *root = [temp valueForKey:@"Root"];
[[root valueForKey:@"Phones"] objectAtIndex:0];

Answer 4

我的“Words.plist”

<dict>
    <key>Root</key>
    <array>
        <string>sunday</string>
        <string>monday</string>
        <integer>44</integer>
    </array>
</dict>


NSString *StringsFromPList = [[NSBundle mainBundle] bundlePath];
NSString *itemPositionPlistLocation = [StringsFromPList stringByAppendingPathComponent:@"Words.plist"];
 _myDictionary= [[NSDictionary alloc] initWithContentsOfFile:itemPositionPlistLocation];
NSArray * items = [_myDictionary objectForKey:@"Root"];
NSLog(@"%@", items);

希望它能有所帮助:)
