iOS 对象信息保存、转化JSON、JSON生成对象的模型方案记录

来源：互联网发布：xp系统网络ip地址设置编辑：程序博客网时间：2024/05/29 14:20

目标：

将对象的一些信息提取保存起来，然后转化成JSON，再上传到服务器，或其他保存本地的用途。

从服务器接收或从本地读取，然后通过JSON的信息生成指定的对象。

方案代码：

通过 Button 以及 Storyboard 上的Label进行测试

1.获取 Label 的信息

    KeepLabelInfoModel* tempModel = [[KeepLabelInfoModel alloc] init];        for (UILabel* subview in self.view.subviews) {        if ([subview isKindOfClass:[UILabel class]]) {                        [tempModel addObject:subview];        }    }    NSLog(@"%@",tempModel.JSONString);

2.删除 Storyboard 上的 Label

    for (UILabel* subview in self.view.subviews) {        if ([subview isKindOfClass:[UILabel class]]) {            [subview removeFromSuperview];        }    }

3.校验生成对象情况

    NSString* tempString = @"["    "{"    "\"textColor\" : \"(0.00, 0.00, 0.67, 1.00)\","    "\"frame\" : \"{{104, 380}, {134, 35}}\","    "\"text\" : \"123\","    "\"transform\" : \"[1, 0, 0, 1, 0, 0]\""    "},"    "{"    "\"textColor\" : \"(0.00, 0.96, 1.00, 1.00)\","    "\"frame\" : \"{{273, 276}, {29, 21}}\","    "\"text\" : \"234\","    "\"transform\" : \"[1, 0, 0, 1, 0, 0]\""    "},"    "{"    "\"textColor\" : \"(0.00, 0.00, 1.00, 1.00)\","    "\"frame\" : \"{{150, 498}, {29, 21}}\","    "\"text\" : \"567\","    "\"transform\" : \"[1, 0, 0, 1, 0, 0]\""    "},"    "{"    "\"textColor\" : \"(0.00, 0.00, 0.00, 1.00)\","    "\"frame\" : \"{{217, 405}, {29, 21}}\","    "\"text\" : \"346\","    "\"transform\" : \"[1, 0, 0, 1, 0, 0]\""    "},"    "{"    "\"textColor\" : \"(0.18, 0.74, 1.00, 1.00)\","    "\"frame\" : \"{{273, 498}, {29, 21}}\","    "\"text\" : \"498\","    "\"transform\" : \"[1, 0, 0, 1, 0, 0]\""    "},"    "]";            KeepLabelInfoModel* tempModel = [[KeepLabelInfoModel alloc] init];        [tempModel modelObjectsWithJSONString:tempString];        for (UIView* subview in tempModel.modelObjects) {        if ([subview isKindOfClass:[UIView class]]) {            [self.view addSubview:subview];        }    }
