一般情況下IOS得局部頁面加載的過程是，創建一個Model然後，將Nib文件與Model進行關聯，然後能夠快速的獲取到Nib文件上的控件實例。操作生成頁面。
但是原生的內容是沒有直接通過Json獲取Model隻能生成字典。然後轉換為Model。下列方法就是通過字典來轉換為Model的過程。
將字典轉換為Model
復制代碼
-(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;
}

復制代碼
-(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;
}

將Model轉換為字典
復制代碼
-(NSDictionary *)convertModelToDictionary
{
NSMutableDictionary *dic = [[NSMutableDictionary alloc] init];
for (NSString *key in [self propertyKeys]) {
id propertyValue = [self valueForKey:key];
//該值不為NSNULL，並且也不為nil
[dic setObject:propertyValue forKey:key];
}
return dic;
}
