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。
首先是要添加对应的使用的头文件#import <objc/runtime.h>
然后添加下面几个方法
Model从字典中填充数据
/*
* 从字典中填充数据
*/
-(int)reflectDataFromDictionary:(NSDictionary *)dic
{
unsigned int useCount ,outCount;
Ivar *ivars = class_copyIvarList([self class], &outCount); for (const Ivar *p = ivars; p < ivars + outCount; p++) {
Ivar const ivar = *p; //获取变量名
NSString *varName = [NSString stringWithUTF8String:ivar_getName(ivar)]; //获取变量值
id varValue = [self valueForKey:varName]; //如果是直接包含此名称的
if ([dic.allKeys containsObject:varName]) {
varValue = [dic objectForKey:varName];
useCount++;
}else{
NSString *tmp_varName = [self removeFirstUnderlined:varName];
if ([dic.allKeys containsObject:tmp_varName]) {
varValue = [dic objectForKey:tmp_varName];
useCount++;
}
} [self setValue:varValue forKey:varName];
} return useCount;
}
两个辅助方法
/*
* 移除掉第一个下划线
*/
-(NSString *)removeFirstUnderlined:(NSString *)str
{
if ([[str substringToIndex:] isEqual:@"_"]) {
return [str substringFromIndex:];
}
return str;
} /*
* 获取所有属性
*/
- (NSArray*)propertyKeys
{
unsigned int outCount, i;
objc_property_t *properties = class_copyPropertyList([self class], &outCount);
NSMutableArray *keys = [[NSMutableArray alloc] initWithCapacity:outCount];
for (i = ; i < outCount; i++) {
objc_property_t property = properties[i];
NSString *propertyName = [[NSString alloc] initWithCString:property_getName(property) encoding:NSUTF8StringEncoding];
[keys addObject:propertyName];
}
free(properties);
return keys;
}
将Model转换为字典
/*
* 转换为字典
*/
-(NSDictionary *)convertToDictionary
{
NSMutableDictionary *dic = [[NSMutableDictionary alloc] init]; for (NSString *key in [self propertyKeys]) {
id propertyValue = [self valueForKey:key];
[dic setObject:propertyValue forKey:key];
} return dic;
}
抽空写了一个Demo出来，GitHub死活上传不上去，所以放到CSDN上去了。如果需要的话可以Down下来看看http://download.csdn.net/detail/anxin1225/8190975
然后，就没有然后了……
