从NSString中的某个字符获取子字符串 [英] Getting the substring from a certain character in NSString

问题描述

如果我最初有一个NSString：

If I have an NSString that is initially:

"ABCDE*FGHI"

如何让它变成

"FGHI"

换句话说，从星号开始的所有内容都会保留。

In other words, everything from the asterisk onwards is kept.

同样，我如何将其变为：

Likewise, how would I turn it into:

"ABCDE"

（保留星号的所有内容）

(everything up to the asterisk is kept)

谢谢

推荐答案

NSString *myString = @"ABCDE*FGHI"; 
NSArray *myArray = [myString componentsSeparatedByString:@"*"];

• myArray的密钥0将包含@ABCDE


• 键1将包含@FGHI



如果您想要多个字符作为分隔符，

使用 componentsSeparatedByCharactersInSet ：

If you want more than one character to be the separator,
use componentsSeparatedByCharactersInSet:

NSString *myString = @"ABCDE*FGHI-JKL"; 
NSArray *myArray = [myString componentsSeparatedByCharactersInSet:[NSCharacterSet characterSetWithCharactersInString:@"*-"]];







• myArray的密钥0将包含@ABCDE


• 键1将包含@FGHI


• 键2将包含@JKL
