【objective-c】字典快速转换为Model代码

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

复制代码

-(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 = [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

复制代码

-(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;
}

复制代码

将Model转换为字典

复制代码

-(NSDictionary *)convertModelToDictionary
{
NSMutableDictionary *dic = [[NSMutableDictionary alloc] init];

for (NSString *key in [self propertyKeys]) {
id propertyValue = [self valueForKey:key];
//该值不为NSNULL，并且也不为nil
[dic setObject:propertyValue forKey:key];
}

return dic;
}
