copyWithZone :(深拷贝）在子类中崩溃
我尝试创建一个赋予NSCopying协议的复制方法。
我有以下课程：
@interface Gene : NSObject <NSCopying>
{
int firstAllele;
int secondAllele;
}
-(id) copyWithZone:(NSZone*) zone
{
id clonedGene = [[[self class] allocWithZone:zone] initWithAllele1:first andAllele2:second];
return clonedGene;
}
Gene* gene1 = [[Gene alloc]initWithAllele1:4 andAllele2:2];
Gene* gene2 = [gene1 copy];
[gene1 copyWithZone:(NSZone *)]
没有找到相关结果

@interface Gene : NSObject { Allele * first; Allele * second; }-(id) copyWithZone:(NSZone*) zone { id clonedGene = [[[self class] allocWithZone:zone] initWithAllele1:[first copy] andAllele2:[second copy]]; return clonedGene; }Allele类中的方法：-(id) copyWithZone:(NSZone*) zone { id copiedAllele = [[[self class] allocWithZone:zone] initWithAllele:allele]; return copiedAllele; }
