称为unaryoperations”“NSMutableArray”菜单”
那么,我们将在类中加入相关的属性。
AddressBook。h
NSMutableArray * _bookArray;
,
@ property(原子、复制)NSMutableArray * bookArray;
AddressBook。m
@ synthesize bookArray=_bookArray; getset
修改响应初始化的方法来完成初始化:
,
,
——(id) initWithName: (NSString *)名称{
,,自我=(超级init);
,,如果(自我){
,,,,_bookName=[[NSString alloc] initWithString:名称];
,,,,_bookArray=[[NSMutableArray alloc] init];
,,,,_bookDictionary=((称为unaryoperations alloc) init);
,,,,,
,,}
,,回归自我;
}

}
使用时:
