1 当我们动态加载某个类的时候，可以用到runtime,可以便捷的获取到动态加载类的所有信息 （属性，属性名）
/**
*测试自动生成某个类
*/
NSDictionary *dict =@{
@"class": @"WaitViewController",
@"property": @{
@"ID": @"123",
@"type": @"12"
}
};
NSString *class =[NSString stringWithFormat:@"%@",dict[@"class"]];
const char *className =[class cStringUsingEncoding:NSUTF8StringEncoding];
Class newClass =objc_getClass(className);
if (!newClass) {
Class superClass =[UIViewController class];
newClass =objc_allocateClassPair(superClass, className, 0);
objc_registerClassPair(newClass);
}
id instance =[[newClass alloc] init];
NSDictionary *propertys =dict[@"property"];
[propertys enumerateKeysAndObjectsUsingBlock:^(id _Nonnull key, id _Nonnull obj, BOOL * _Nonnull stop) {
//加载类中的属性
NSLog(@"%@",key);
unsigned int outCount, i;
objc_property_t *property1 =class_copyPropertyList([instance class], &outCount);
for (i=0; i<outCount; i++) {
objc_property_t property =property1[i];
NSLog(@"%s",property_getAttributes(property));
// NSLog(@"%@",method_getName((__bridge Method)(instance)));
NSString *propertyName =[[NSString alloc] initWithCString:property_getName(property) encoding:NSUTF8StringEncoding];
if ([propertyName isEqualToString:key]) {
NSLog(@"yes");
}
}
}];
