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
{
unsignedintuseCount ,outCount;
Ivar*ivars = class_copyIvarList([selfclass], &outCount);for(constIvar *p = ivars; p < ivars + outCount; p++) {
Ivarconstivar = *p;//获取变量名NSString *varName =[NSString stringWithUTF8String:ivar_getName(ivar)];//获取变量值idvarValue =[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];
}returnuseCount;
}
两个辅助方法
/** 移除掉第一个下划线*/-(NSString *)removeFirstUnderlined:(NSString *)str
{if([[str substringToIndex:1] isEqual:@"_"]) {return[str substringFromIndex:1];
}returnstr;
}/** 获取所有属性*/- (NSArray*)PRopertyKeys
{
unsignedintoutCount, i;
objc_property_t*properties = class_copyPropertyList([selfclass], &outCount);
NSMutableArray*keys =[[NSMutableArray alloc] initWithCapacity:outCount];for(i =0; i < outCount; i++) {
objc_property_t property=properties[i];
NSString*propertyName =[[NSString alloc] initWithCString:property_getName(property) encoding:NSUTF8StringEncoding];
[keys addObject:propertyName];
}
free(properties);returnkeys;
}
将Model转换为字典
/** 转换为字典*/-(NSDictionary *)convertToDictionary
{
NSMutableDictionary*dic =[[NSMutableDictionary alloc] init];for(NSString *keyin[self propertyKeys]) {idpropertyValue =[self valueForKey:key];
[dic setObject:propertyValue forKey:key];
}returndic;
}
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……
