如下圖：

從user_logs表格select出來的資料放在一個可變陣列NSMutableArray中，如 user_logs,現在要

@interface UserLog : NSObject
@property(strong,nonatomic) NSString * logId;
@property(strong,nonatomic) NSString * userId;
@property(strong,nonatomic) NSString * actionType;
@property(strong,nonatomic) NSDate * actionDate;
@property(strong,nonatomic) NSString * accountNumber;
@property(strong,nonatomic) NSString * dataRef1;
@property(strong,nonatomic) NSString * dataRef2;
@property(strong,nonatomic) NSString * dataRef3;
@property(nonatomic) BOOL uploaded;
@property(nonatomic) NSInteger udts;
@property(strong,nonatomic) NSString * logType;


- (NSDictionary *)convertToDictionary;
@end
 

-(NSDictionary *)convertUserLogsPropertyToDictionary:(NSMutableArray *)userLogs{
    NSMutableArray  *userLogsMutableArray = [NSMutableArray array];
    for (int i = 0;i< [userLogs count];i++) {
        UserLog *userLog = userLogs[i];
        [userLogsMutableArray addObject:[userLog convertToDictionary]];
    }
    NSDictionary *userLogsDictionary = @{@"objects":userLogsMutableArray};
    return userLogsDictionary;
}
