Question

我有一个我正在创建的plist文件，但是我没有写入文件，而是将其内容作为字符串打印到NSLog：

NSMutableDictionary* root = [NSMutableDictionary dictionaryWithCapacity:1];
NSMutableArray* puzzle = [NSMutableArray arrayWithCapacity: [self.puzzlePieces count] ];
root[@"puzzle"] = puzzle;

[self.puzzlePieces enumerateObjectsUsingBlock:^(KTPuzzlePiece* piece, NSUInteger idx, BOOL *stop) {
    NSMutableDictionary* pieceInfo = [piece.pieceInfo mutableCopy];
    pieceInfo[@"x"] = [NSNumber numberWithFloat: piece.position.x];
    pieceInfo[@"y"] = [NSNumber numberWithFloat: piece.position.y];

    [puzzle addObject:pieceInfo];
}];


NSData *data = [NSPropertyListSerialization dataFromPropertyList:root
                                                          format:NSPropertyListXMLFormat_v1_0
                                                errorDescription:nil];

但是，以下输出十六进制值

    NSLog(@"Data: %@", data);

你只是错过了一步。你需要将你的NSData转换成一个字符串，你应该好好去：

NSData *data = [NSPropertyListSerialization 
                       dataFromPropertyList:root
                                     format:NSPropertyListXMLFormat_v1_0
                           errorDescription:nil];

NSString *string = [[NSString alloc] initWithData:data encoding:NSUTF8StringEncoding];

NSLog(@"%@", string);

将plist文件打印到NSLog
