主要做一下汇总。
1。首先还是官方文档Archives and Serializations Programming Guide

3.如何保存游戏数据
http://hi.baidu.com/shadowstudios/blog/item/49186df160dbf628bc31090c.html
说说对象归档NSKeyedArchiver和NSKeyedUnarchiver的存储。
比如我要存储
UploadItem，那么它必须继承自<NSCoding>,
@interface UploadItem : NSObject<NSCoding> {
FileOrigin type;
NSString *filepath;
VideoInfo *video;
}
实现两个方法
- (void)encodeWithCoder:(NSCoder *)aCoder
{
[aCoder encodeObject: self.filepath forKey:@"uploaditem_filepath"];
[aCoder encodeObject: self.video forKey:@"uploaditem_video"];
[aCoder encodeInt:self.type forKey:@"uploaditem_type"];
}
- (id)initWithCoder:(NSCoder *)aDecoder
{
[self init];
self.filepath = [aDecoder decodeObjectForKey:@"uploaditem_filepath"];
self.video = [aDecoder decodeObjectForKey:@"uploaditem_video"];
self.type = (FileOrigin)[aDecoder decodeIntForKey:@"uploaditem_type"];
return self;
}
这样比如外部有一个NSMutableArray* array存储的是
UploadItem，那么我直接调用
[aCoder encodeObject: self.array forKey:@"uploadprocess_array"];
可以存储整个UploadItem类的数组。
读取的时候
self.array = [aDecoder decodeObjectForKey:@"uploadprocess_array"];
就ok了
