我有以上内容作为回应。我只想将该字符串更改为下面。
怎么获得:
href="/lernmodule/histologie/quergestreifte+muskulatur+histologie#_5AD480AC_7D6C_4AA6_B003_F1C5F38F4D15"
从上面的字符串?
最佳答案
如果您的回答的格式是特定的,如您的问题中所示,那么下面的代码将为您服务:
NSString *match = @"internal";
NSString *postTel;
NSString *preTel;
NSScanner *scanner = [NSScanner scannerWithString:str];
[scanner scanUpToString:match intoString:&preTel];
[scanner scanString:match intoString:nil];
postTel = [str substringToIndex:scanner.scanLocation];
NSString*requiredString=[[postTel substringFromIndex:3] stringByReplacingOccurrencesOfString:@"internal" withString:@""];
