iOS归档自定义对面时,其中image属性怎么反序列化的时候为nil,下面是代码

//编码

• (void)encodeWithCoder:(NSCoder *)aCoder{

  [aCoder encodeObject:_name forKey:@"name"];

  [aCoder encodeInteger:_age forKey:@"age"];

  [aCoder encodeObject:_phoneNo forKey:@"phoneNo"];

  [aCoder encodeObject:_image forKey:@"image"];

  NSLog(@"111%@",_image);

}

//解码

• (instancetype)initWithCoder:(NSCoder *)aDecoder{

  _name = [aDecoder decodeObjectForKey:@"name"];

  _age = [aDecoder decodeIntegerForKey:@"age"];

  _phoneNo = [aDecoder decodeObjectForKey:@"phoneNo"];

  _image = [aDecoder decodeObjectForKey:@"image"];

  NSLog(@"222%@",[aDecoder decodeObjectForKey:@"image"]);

  return self;

}
其他三个属性都是有值的

Person对象定义属性的时候,UIImage直接敲好像出不来 ,手动加入了UIKit.h
#import
#import
@interface Person : NSObject
@property (strong, nonatomic) NSString *name;
@property (assign, nonatomic) NSInteger age;
@property (strong, nonatomic) NSString *phoneNo;
@property (strong, nonatomic) UIImage *image;
@end

不知道是不是这个原因导致的?求大神解答疑惑,谢谢了
