效果图

实现原理

1. 配置Info.plist文件，加入自定义的字段：
   ProjectDir : $(SRCROOT)/$(PROJECT_NAME)
2. 遍历dictionary中的key和value，拼接字符串：@property(nonatomic,cop)NSString *key;
3. 分类整理-纯为了简洁
4. 保存到指定的.h文件中
5. 用NSAssert进行了出错提示，比如没有配置ProjectDir、.h文件找不到、.h文件读取失败

实现代码-核心

PropertiesGenerator.m

// 分类
    NSMutableArray *propertiesArray = [NSMutableArray array];
    NSMutableArray *NSStringArray = [NSMutableArray array];
    NSMutableArray *NSDictinoaryArray = [NSMutableArray array];
    NSMutableArray *NSArrayArray = [NSMutableArray array];
    NSMutableArray *BOOLArray = [NSMutableArray array];
    NSMutableArray *floatArray = [NSMutableArray array];
[dict enumerateKeysAndObjectsUsingBlock:^(id  _Nonnull key, id  _Nonnull obj, BOOL * _Nonnull stop) {
        NSString *str;
        if ([self class:obj isKindOfClass:@"__NSCFString"] || [self class:obj isKindOfClass:@"NSTaggedPointerString"] || [self class:obj isKindOfClass:@"__NSCFConstantString"]) {
            str = [NSString stringWithFormat:@"@property(nonatomic,copy)NSString *%@;",key];
            [NSStringArray addObject:str];
        }
        else if ([self class:obj isKindOfClass:@"__NSCFNumber"]) {
            str = [NSString stringWithFormat:@"@property(nonatomic,assign)float %@;",key];
            [floatArray addObject:str];
        }
        else if ([self class:obj isKindOfClass:@"__NSCFArray"] || [self class:obj isKindOfClass:@"__NSArrayI"]) {
            str = [NSString stringWithFormat:@"@property(nonatomic,copy)NSArray *%@;",key];
            [NSArrayArray addObject:str];
        }
        else if ([self class:obj isKindOfClass:@"__NSCFDictionary"] || [self class:obj isKindOfClass:@"__NSDictionaryI"]) {
            str = [NSString stringWithFormat:@"@property(nonatomic,copy)NSDictionary *%@;",key];
            [NSDictinoaryArray addObject:str];
        }
        else if ([self class:obj isKindOfClass:@"__NSCFBoolean"]) {
            str = [NSString stringWithFormat:@"@property(nonatomic,assign)BOOL %@;",key];
            [BOOLArray addObject:str];
        }
    }];

    [propertiesArray addObjectsFromArray: NSStringArray];
    [propertiesArray addObjectsFromArray: NSDictinoaryArray];
    [propertiesArray addObjectsFromArray: NSArrayArray];
    [propertiesArray addObjectsFromArray: BOOLArray];
    [propertiesArray addObjectsFromArray: floatArray];
    propertiesString = [propertiesArray componentsJoinedByString:@"\n"];

// 然后写入到.h文件中

用法

#import "PropertiesGenerator.h"
     NSDictionary *dict = @{
                           @"name": @"zhuxuhong",
                           @"age": [NSNumber numberWithFloat:22],
                           @"nickname": @"flytoo",
                           @"friends": @[@"1",@"2",@"3"],
                           @"experience": @{@"2016": @"BISTU"},
                           @"password": @"1234",
                           @"education": @{@"2016": @"BISTU"},
                           @"graduated": [NSNumber numberWithBool:true]
                           };
    
    [[PropertiesGenerator generator] autoGeneratePropertiesInModelClass:@"Me" Dictionary:dict]; //判断是否写入成功
