1、一句代码自动生成模型属性

.h文件

#import <Foundation/Foundation.h>

@interface NSDictionary (Property)

- (void)createPropertyCode;

@end

.m文件

#import "NSDictionary+Property.h"

@implementation NSDictionary (Property)

- (void)createPropertyCode{

     [self enumerateKeysAndObjectsUsingBlock:^(id  _Nonnull key, id  _Nonnull obj, BOOL * _Nonnull stop) {

    NSString *code = nil;

  if ([obj isKindOfClass:[NSString class]]) {

          code = [NSString stringWithFormat:@"@property (nonatomic, copy) NSString *%@;",key];

     }else if ([obj isKindOfClass:[NSNumber class]]){

            code = [NSString stringWithFormat:@"@property (nonatomic, assign) NSInteger %@;",key];

        }else if ([obj isKindOfClass: NSClassFromString(@"__NSCFBoolean")]){

            code = [NSString stringWithFormat:@"@property (nonatomic, assign) BOOL %@;",key];

        }else if ([obj isKindOfClass:[NSArray class]]) {

            code = [NSString stringWithFormat:@"@property (nonatomic, copy) NSArray *%@;",key];

        } else if ([obj isKindOfClass:[NSDictionary class]]) {

            code = [NSString stringWithFormat:@"@property (nonatomic, copy) NSDictionary *%@;",key];

        }

        [codes appendFormat:@"\n%@\n",code];

    }];

    NSLog(@"%@",codes);

}

@end

2、字典转模型

.h文件

#import <Foundation/Foundation.h>

@interface XSDictModel : NSObject

//字典转模型

+ (instancetype)modelWithDict:(NSDictionary *)dict;

@end

.m文件

#import "XSDictModel.h"

#import <objc/message.h>

@implementation XSDictModel

+ (instancetype)modelWithDict:(NSDictionary *)dict{

    id objc = [[self alloc] init];

    //1.获取成员变量

    unsigned int count = 0;

    //获取成员变量数组

    Ivar *ivarList = class_copyIvarList(self, &count);

    for (int i = 0; i < count; i++) {

        //获取成员变量

        Ivar ivar = ivarList[i];

        //获取成员变量名称

        NSString *ivarName = [NSString stringWithUTF8String:ivar_getName(ivar)];

        //获取成员变量类型

        NSString *ivarType = [NSString stringWithUTF8String:ivar_getTypeEncoding(ivar)];

       ivarType = [ivarType stringByReplacingOccurrencesOfString:@"\"" withString:@""];

        ivarType = [ivarType stringByReplacingOccurrencesOfString:@"@" withString:@""];

        //获取key

        NSString *key = [ivarName substringFromIndex:1];

        id value = dict[key];

        // 二级转换:判断下value是否是字典,如果是,字典转换层对应的模型

        // 并且是自定义对象才需要转换

        if ([value isKindOfClass:[NSDictionary class]] && ![ivarType hasPrefix:@"NS"]){

            //获取class

            Class modelClass = NSClassFromString(ivarType);

            value = [modelClass modelWithDict:value];

        }

        if (value) {

            [objc setValue:value forKey:key];

        }

    }

    return objc;

}
