我想在数组中或在保存之前合并两个对象

我正在从 ABpeoplepickerNavcontroller 保存名字和姓氏,我想在保存到数组之前合并名字和姓氏,以便当我检索它时,它们会在一起。第一个代码是正在创建的对象:

// setting the first name
firstName.text = (NSString *)ABRecordCopyValue(person, kABPersonFirstNameProperty);

// setting the last name
lastName.text = (NSString *)ABRecordCopyValue(person, kABPersonLastNameProperty);   

这是我保存它的位置:

NSMutableArray *array = [[NSMutableArray alloc] init];
[array addObject:firstName.text];
[array addObject:lastName.text];
[array addObject:addressLabel.text];

[array writeToFile:recipient atomically:NO];
[array release];

我可以在一行上保存添加两个对象吗?或者我可以在添加到数组之前合并对象吗?

谢谢,郑重声明……这个网站和帮助我的人都很棒。

I am saving the first and last name from ABpeoplepickerNavcontroller, I would like to merge the first and last name prior to saving into an array so that when i retrieve it, they would be together. The first code is the object being created:

// setting the first name
firstName.text = (NSString *)ABRecordCopyValue(person, kABPersonFirstNameProperty);

// setting the last name
lastName.text = (NSString *)ABRecordCopyValue(person, kABPersonLastNameProperty);   

Here's where I save it:

NSMutableArray *array = [[NSMutableArray alloc] init];
[array addObject:firstName.text];
[array addObject:lastName.text];
[array addObject:addressLabel.text];

[array writeToFile:recipient atomically:NO];
[array release];

Can I save add two objects on one line? or Can I merge the objects prior to adding to array?

Thanks, and for the record...this site and the people who have helped me have been fantastic.

我不确定你所说的合并是什么意思。如果要将一个字符串附加到另一个字符串,请执行以下操作:

NSString *joinedNamed = [NSString stringWithFormat:@"%@ %@", firstName.text, lastName.text]; 

I am not sure what you mean by merging. If you want to append one string to the other do the following:

NSString *joinedNamed = [NSString stringWithFormat:@"%@ %@", firstName.text, lastName.text];

您可以像这样使用stringByAppendingString

[array addObject:[firstName.text stringByAppendingString:lastName.text]];

You can use the stringByAppendingString like this:

[array addObject:[firstName.text stringByAppendingString:lastName.text]];

来自 iPhone 通讯录编程指南:

“然而,在实际应用中,推荐使用 ABRecordCopyCompositeName 函数来显示一个人的全名。它将名字和姓氏按照用户喜欢的顺序排列,这提供了更统一的用户体验。”

这里的解决方案可以工作,但如果您只使用复合名称,您可能根本不需要这样做。

From the Address Book Programming Guide for iPhone:

"However, in actual applications, the function ABRecordCopyCompositeName is the recommended way to get a person’s full name to display. It puts the first and last name in the order preferred by the user, which provides a more uniform user experience."

The solutions here will work but it's something you may not need to do at all if you just use the composite name.
