Model属性自动赋值(继续Model那些事)

之前写了给文章写了给数据中数组里数据自动转成Model类的文章http://www.jianshu.com/p/f86795aa7b09
刚刚有想了想写了一个Model类属性自动赋值的
怕麻烦直接分享代码--注释写的挺多的

/**
 将字典中的属性自动赋值到Model类中

 @param dic 数据字典
 @param removeNames 不需要自动赋值的类
 @param namesDic 转换属性名字字典@{属性名字：在数据中对应名字}
 */
-(void)changing_properties:(NSDictionary *)dic removePropertys:(NSArray<NSString *> *)removeNames beChangeObjNames:(NSDictionary *)namesDic;

//方法实现
-(void)changing_properties:(NSDictionary *)dic removePropertys:(NSArray<NSString *> *)removeNames beChangeObjNames:(NSDictionary *)namesDic{
    NSMutableArray *allNames = [[self getAllProperties] mutableCopy];//获取属性列表
    
    //移除用户要删除的属性
    if (removeNames != nil && removeNames.count != 0) {
        [allNames removeObjectsInArray:removeNames];
    }
    
    //将属性赋值 主要用performSelector调用set方法
    [allNames enumerateObjectsUsingBlock:^(NSString * _Nonnull obj, NSUInteger idx, BOOL * _Nonnull stop) {
        ///准备方法名字
        NSString *functionName = [NSString stringWithFormat:@"set%@:", [self changeFirstCharBig:obj]];
        SEL selector = NSSelectorFromString(functionName);
        
        ///准备属性对应value
        NSString * objContent = @"";
        //判断属性字段在数据字典中有没有对应的值，没有的话调用属性名转化数组替换属性名字
        if ([namesDic objectForKey:obj] == nil) {
            objContent = [dic objectForKey:obj];
        }else{
//            NSAssert([namesDic objectForKey:obj] != nil, @"属性名字转化错误或数据中没有该字段");
            objContent = [dic objectForKey:[namesDic objectForKey:obj]];
        }
        
        ///调用set方法赋值
        if ([self respondsToSelector:selector]) {
#pragma clang diagnostic push
#pragma clang diagnostic ignored "-Warc-performSelector-leaks"
            [self performSelector:selector withObject:objContent];
#pragma clang diagnostic pop
        }
    }];
}

//获取该类的所有属性
-(NSArray *)getAllProperties{
    unsigned int count;
    objc_property_t *properties = class_copyPropertyList([self class], &count);
    NSMutableArray * arr = [[NSMutableArray alloc]init];
    for(int i = 0; i < count; i++){
        objc_property_t property = properties[i];
        [arr addObject:[NSString stringWithFormat:@"%s", property_getName(property)]];
    }
    free(properties);
    return arr;
}

//将字符串首字母大写
-(NSString *)changeFirstCharBig:(NSString *)string{
    NSString *upstring = [string uppercaseString];
    string = [string substringFromIndex:1];
    upstring = [upstring substringToIndex:1];
    return [NSString stringWithFormat:@"%@%@", upstring, string];
}
