如何使用NSLineSeparatorCharacter和NSParagraphSeparatorCharacter? [英] How to use NSLineSeparatorCharacter and NSParagraphSeparatorCharacter?

问题描述

我想知道如何使用常量NSLineSeparatorCharacter和NSParagraphSeparatorCharacter作为函数的参数，而不是对\n进行硬编码.

I wonder how I can use the constants NSLineSeparatorCharacter and NSParagraphSeparatorCharacter as a parameter to a function instead of hard coding \n.

- (id)initWithSeparator:(id)separator {
 m_separator = separator;
}

正确的参数类型是什么，需要进行哪些转换?
根据文件的内容，我希望调用类似...的函数.

What would be the correct parameter type and what conversion needs to be done?
Depending on the file contents I wish to call the function like ...

Object* obj = [[Object alloc] initWithSeparator:NSLineSeparatorCharacter];

...或...

Object* obj = [[Object alloc] initWithSeparator:NSParagraphSeparatorCharacter];

Apples 字符串编程指南/段落和但是，换行符没有帮助.

Apples String Programming Guide / Paragraphs and Line Breaks was not helpful, though.

推荐答案

正确的参数类型为unichar-无需进行任何转换?如果以后要创建NSString，则必须使用

The correct parameter type would be unichar - no need to convert anything? If you want to create an NSString later, you'll have to use something like

    unichar myChar = NSParagraphSeparatorCharacter;
    NSString *myString = [NSString stringWithCharacters:&myChar length:1];
