Question

我是iphone的初学者谢谢你给我回答...... 我想将NSMutable字符串分解为子字符串

200,8,"7 Infinite Loop, Cupertino, CA 95014, USA"

我只想要来自Mutable String之上的Cupertino和CA. 可以在iphone中使用objective-C 以上数据是可变数据，来自httprequest对象。我想从同一种类型的可变字符串中获取城市和州名。请给我解决方案，它为我创造了很多hedac。

Answer 1

如果这是CSV数据，请查看

Answer 2

一种方法是用逗号分割字符串并修剪空格：

NSArray *substrings = [myString componentsSeparatedByString: @","];
NSCharacterSet *whitespace = [NSCharacterSet whitespaceCharacterSet];
NSMutableArray *result = [NSMutableArray array];
for ( NSString *str in substrings )
    [result addObject: [str stringByTrimmingCharactersInSet: whitespace]];

Answer 3

您希望以此格式分解所有字符串吗？

NSArray *myArray = [string componentsSeparatedByString:@","];
NSString * strippedNumbers = [[myArray objectAtIndex:4] stringByReplacingOccurrencesOfRegex:@"[^0-9]" withString:@""];
NSString *myString = [NSString stringWithFormat:@"%@ %@", [myArray objectAtIndex:3], strippedNumbers];

我如何在iphone中的objective-C中从NSMutableString中断或创建NSMutableSubstrings？
