How to split items in a string separated by ","

In my App, data comes in Str开发者_JAVA百科ing like this

"Hi,Hello,Bye"

I want to separate data by ","

How can I do that?

---

use componentsSeparatedByString:

NSString *str = @"Hi,Hello,Bye";  
NSArray *arr = [str componentsSeparatedByString:@","];  
NSString *strHi = [arr objectAtIndex:0];  
NSString *strHello = [arr objectAtIndex:1];
NSString *strBye = [arr objectAtIndex:2];

---

NSString *str = @"Hi,Hello,Bye";

NSArray *aArray = [str componentsSeparatedByString:@","];

For more info, look at this post.

Well, the naïve approach would be to use componentsSeparatedByString:, as suggested in the other answers.

However, if your data is truly in the CSV format, you'd do well to consider using a proper CSV parser, such as this one (which I wrote): https://github.com/davedelong/CHCSVParser

Use [myString componentsSeparatedByString:@","].

If it's NSString, you can use componentsSeparatedByString.

If it's std::string, you can iterate looking for the item (using find_frst_of and substr)

---

NSArray *components = [@"Hi,Hello,Bye" componentsSeparatedByString:@","];
