IOS 字典快速转换为Model

一般情况下IOS得局部页面加载的过程是,创建一个Model然后,将Nib文件与Model进行关联,然后能够快速的获取到Nib文件上的控件实例。操作生成页面。

但是原生的内容是没有直接通过Json获取Model只能生成字典。然后转换为Model。下列方法就是通过字典来转换为Model的过程。

 

将字典转换为Model

-(BOOL)reflectDataFromOtherObject:(NSDictionary *)dic{    unsigned int outCount, i;    objc_property_t *properties = class_copyPropertyList([self class], &outCount);        for (i = 0; i < outCount; i++) {        objc_property_t property = properties[i];        NSString *propertyName = [[NSString alloc] initWithCString:property_getName(property) encoding:NSUTF8StringEncoding];        NSString *propertyType = [[NSString alloc] initWithCString:property_getAttributes(property) encoding:NSUTF8StringEncoding];                if ([[dic allKeys] containsObject:propertyName]) {            id value =http://www.mamicode.com/ [dic valueForKey:propertyName];            if (![value isKindOfClass:[NSNull class]] && value != nil) {                if ([value isKindOfClass:[NSDictionary class]]) {                    id pro = [self createInstanceByClassName:[self getClassName:propertyType]];                    [pro reflectDataFromOtherObject:value];                    [self setValue:pro forKey:propertyName];                }else{                    [self setValue:value forKey:propertyName];                }            }        }    }        free(properties);    return true;}

其他两个辅助类型方法

-(NSString *)getClassName:(NSString *)attributes{    NSString *type = [attributes substringFromIndex:[attributes rangeOfRegex:@"\""].location + 1];    type = [type substringToIndex:[type rangeOfRegex:@"\""].location];    return type;}-(id) createInstanceByClassName: (NSString *)className {    NSBundle *bundle = [NSBundle mainBundle];    Class aClass = [bundle classNamed:className];    id anInstance = [[aClass alloc] init];    return anInstance;}

 

将Model转换为字典

-(NSDictionary *)convertModelToDictionary{    NSMutableDictionary *dic = [[NSMutableDictionary alloc] init];        for (NSString *key in [self propertyKeys]) {        id propertyValue =http://www.mamicode.com/ [self valueForKey:key];        //该值不为NSNULL,并且也不为nil        [dic setObject:propertyValue forKey:key];    }        return dic;}
