ios - 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 的新手)

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;}

因为 temp 是一个字典，只包含一个键:@"Root"。您正在内部字典中寻找一个对象:[[temp objectForKey:@"Root"] objectForKey:@"Name"]
