利用KVC原理完全自定义数据转模型, 更多功能长期迭代更新中
用法 :
1 > 新建你的model类然后继承ZHModel
2 > 新建model中, 写入你的属性
3 > 然后调用对象方法就可直接解析

核心代码:
- (void)ZH_setValue:(nullableid)value forKey:(NSString*)key{
if(key ==nil|| key.length==0) {
NSLog(@"传入的key为nil或者key长度为0");
return;
}
[selfsetValue:valueforKey:key];
NSString *setKey = [NSString stringWithFormat:@"set%@:", key.capitalizedString];
NSString *setIsKey = [NSString stringWithFormat:@"setIs%@:", key.capitalizedString];
if([self respondsToSelector:NSSelectorFromString(setKey)]){
[self performSelector:NSSelectorFromString(setKey) withObject:value];
return;
}
if([self respondsToSelector:NSSelectorFromString(setIsKey)]){
[self performSelector:NSSelectorFromString(setIsKey) withObject:value];
return;
}
if (![self.class accessInstanceVariablesDirectly]){
// 异常
NSException *exception = [NSException exceptionWithName:@"ZH_EXCEPTION" reason:[NSString stringWithFormat:@"你没有实现这个key:'%@'的setter方法, 而且你还不允许访问成员变量", key] userInfo:nil];
@throwexception;
return;
}
unsignedintcount =0;
Ivar*ivars =class_copyIvarList(self.class, &count);
NSMutableArray *ivarArr = [NSMutableArray arrayWithCapacity:0];
for(inti =0; i < count; i++) {
Ivarivar = ivars[i];
constchar*bianlaing_name =ivar_getName(ivar);
[ivarArraddObject:[NSStringstringWithFormat:@"%s", bianlaing_name]];
}
for(inti =0; i < count; i++) {
NSString*keyName = ivarArr[i];
Ivarivar = ivars[i];
if([keyNameisEqualToString:[NSStringstringWithFormat:@"_%@", key]]) {
object_setIvar(self, ivar, value);
free(ivars);
return;
}
}

}
}
