ios有感而发，看到c#的mvvm结构，ios搞个相似的。不彻底同样（第二步）

#import <UIKit/UIKit.h>
@protocol IQuery

@required
-(void) initclassdata:(NSDictionary *)dataDic;

@end


@interface IServicebase:NSObject<IQuery>



@end

#import <Foundation/Foundation.h>
#import "IServicebase.h"
#import <objc/runtime.h>

@implementation IServicebase
-(void) initclassdata:(NSDictionary *)dataDic{
    
    if (dataDic == nil) {
        return;
    }
    NSArray *kaylist = [dataDic allKeys];
    for (NSString *kay in kaylist) {
        if ([self getVariableWithClass:self.class varName:kay]) {
            [self setValue:[dataDic objectForKey:kay] forKey:kay];
        }
    }
    
}

//判断是否包含一个属性
- (BOOL) getVariableWithClass:(Class) myClass varName:(NSString *)name{
    unsigned int outCount, i;
    Ivar *ivars = class_copyIvarList(myClass, &outCount);
    for (i = 0; i < outCount; i++) {
        Ivar property = ivars[i];
        NSString *keyName = [NSString stringWithCString:ivar_getName(property) encoding:NSUTF8StringEncoding];
        keyName = [keyName stringByReplacingOccurrencesOfString:@"_" withString:@""];
        if ([keyName isEqualToString:name]) {
            return YES;
        }
    } return NO;
    
}
@end

上述俩个图是iservice的后续完善。结合前一章，用户可继承此类，创建本身的service。
