如何使用GameKit蓝牙将NSDictionary(或plist文件)作为NSData发送? [英] How to send an NSDictionary (or plist file) as NSData using GameKit bluetooth?

问题描述

我正在尝试使用

[currentSession sendDataToAllPeers:data withDataMode:GKSendDataReliable error:nil];

将包含数据的NSDictionary(或plist文件)从一台设备发送到另一台设备，并且

to send an NSDictionary (or a plist file) containing data from 1 device to another, and

- (void)receiveData:(NSData *)data fromPeer:(NSString *)peer inSession:(GKSession *)session context:(void *)context

接收它.我该如何与NSData进行相互转换?

to receive it. How can I convert to and from NSData for this to happen?

推荐答案

您可以使用以下命令将Plist转换为NSData:

You can use the following to transform Plist to NSData:

+ (NSData *)dataWithPropertyList:(id)plist
                          format:(NSPropertyListFormat)format
                         options:(NSPropertyListWriteOptions)opt
                           error:(NSError **)error

然后将NSData转换为Plist:

And this to transform NSData to Plist:

+ (id)propertyListWithData:(NSData *)data
                   options:(NSPropertyListReadOptions)opt
                    format:(NSPropertyListFormat *)format
                     error:(NSError **)error

of <代码> NSPropertyListSerialization 类

format 可以是 NSPropertyListBinaryFormat_v1_0 以使用最低字节数

format could be NSPropertyListBinaryFormat_v1_0 to use lowest byte count
