如何使用Objective-C按空格分隔字符串? [英] How to separate string by space using Objective-C?

问题描述

假设我有一个像这样的字符串:

Assume that I have a String like this:

hello world       this may     have lots   of sp:ace or little      space

我想将此字符串分隔为:

I would like to seperate this String to this:

@"hello", @"world", @"this", @"may", @"have", @"lots", @"of", @"sp:ace", @"or", @"little", @"space"

谢谢.

推荐答案

NSString *aString = @"hello world       this may     have lots   of sp:ace or little      space";
NSArray *array = [aString componentsSeparatedByCharactersInSet:[NSCharacterSet whitespaceCharacterSet]];
array = [array filteredArrayUsingPredicate:[NSPredicate predicateWithFormat:@"SELF != ''"]];
