iOS-使用空格解析字符串

我是一个iOS新手，所以如果这是一个初级问题，请原谅我

---

我有一个字符串“hu_-hu hu Hungarian:Hungarian”，我想把它放入一个类似{“hu”，“hu”，“hu”，“Hungarian:Hungarian”}的数组中。如何解析它以删除空格，然后删除下划线？

使用NSString的方法要获得所需的效果，必须将“u”更改为“”或反之亦然。然后可以使用ComponentSeparatedByString，如下所示：

NSString *source = @"hu_HU Hungary:Hungarian";
source = [source stringByReplacingOccurrencesOfString:@"_" withString:@" "];
NSArray *components = [source componentsSeparatedByString:@" "];
NSLog(@"%@",components);

给你：

NSString *myString = @"hu_HU Hungary:Hungarian";
myString = [myString stringByReplacingOccurrencesOfString:@"_" withString:@" "];
NSArray *myArray = [myString componentsSeparatedByString:@" "];

所有这些答案都有一个恼人的问题。他们假设项目之间只有一个空间

NSString *theStr = @"hu_HU Hungary:Hungarian";
NSArray  *pieces = [theStr componentsSeparatedByCharactersInSet: [NSCharacterSet characterSetWithCharactersInString: @"_ "]];
//pieces = {"hu", "HU", "Hungary:Hungarian"}

NSString *theStr = @"hu_HU  Hungary:Hungarian"; // note extra space
NSArray  *pieces = [theStr componentsSeparatedByCharactersInSet: [NSCharacterSet characterSetWithCharactersInString: @"_ "]];
//pieces = {"hu", "HU", " ", "Hungary:Hungarian"}

NSString *theStr = @"hu_HU Hungary:Hungarian";
NSArray  *pieces = [theStr componentsSeparatedByCharactersInSet: [NSCharacterSet characterSetWithCharactersInString: @"_ "]];
//pieces = {"hu", "HU", "Hungary:Hungarian"}

NSString *theStr = @"hu_HU  Hungary:Hungarian"; // note extra space
NSArray  *pieces = [theStr componentsSeparatedByCharactersInSet: [NSCharacterSet characterSetWithCharactersInString: @"_ "]];
//pieces = {"hu", "HU", " ", "Hungary:Hungarian"}
