您可以按照以下方式进行

NSString *aStrImageName     = [NSString stringWithFormat:@"splash_ipad.png"];
    UIImage *aImg               = [UIImage imageNamed:aStrImageName];
    NSDictionary *aDictData     = [NSDictionary dictionaryWithObjectsAndKeys:aStrImageName,@"ImageName",aImg,@"Image", nil];
    NSData *aObjData            = [NSKeyedArchiver archivedDataWithRootObject:aDictData];
    NSDictionary *aDictBack     = (NSDictionary*) [NSKeyedUnarchiver unarchiveObjectWithData:aObjData];
    NSString *aStrImageNameBack = [aDictBack valueForKey:@"ImageName"];
    UIImage *aImgBack           = [aDictBack objectForKey:@"Image"];
