如何从NSString Xcode获取两个单独的值

Question

.es(metric=cardinality:geoip.ip)

在字符串上方，我需要获得两个单独的字符串，就像后面一样。

NSString *mystring = @"123 This is testing message";

有没有快速的方法从NSString *one = @"123"; NSString *Two = @"This is testing message"; 检索两个单独的字符串？

Answer 1

您可以使用此

  - (NSString *)extractNumberFromText:(NSString *)text
  {
    NSCharacterSet *nonDigitCharacterSet = [[NSCharacterSet decimalDigitCharacterSet] invertedSet];
    return [[text componentsSeparatedByCharactersInSet:nonDigitCharacterSet] componentsJoinedByString:@""];
  }

致电

NSString * str = @"123 This is testing message";
NSString *number = [self extractNumberFromText:str];
NSString *text = [str substringFromIndex:number.length+1];
