iphone - tooltipHtml - 从谷歌地图调用中提取

Question

" (2.1\x26#160;mi / 7 分钟)"

我有上面的字符串，我只需要到达距离和时间。我将如何使用 RegexKitLite 脚本执行此操作？理想情况下，以下是我正在寻找的内容：

时间 = 7 分钟距离 = 2.1 英里

谢谢

不是使用 RegexKitLite 脚本，但我是这样做的：

NSString* tooltipHtml = [apiResponse stringByMatching:@"tooltipHtml:\\"([^\\"]*)\\"" capture:1L];

NSLog(@"tooltip Html: %@", tooltipHtml);


int leftParanthesis = [tooltipHtml rangeOfString:@"("].location;
int inverseSlash = [tooltipHtml rangeOfString:@"\\"].location;
int slash = [tooltipHtml rangeOfString:@"/"].location;
int semiColumn = [tooltipHtml rangeOfString:@";"].location;
int rightParanthesis = [tooltipHtml rangeOfString:@")"].location;


NSRange distanceRange = NSMakeRange(leftParanthesis+1, inverseSlash-leftParanthesis-1);
NSString *distance = [tooltipHtml substringWithRange:distanceRange];

NSRange distanceTypeRange = NSMakeRange(semiColumn+1, slash-semiColumn-1);
NSString *distanceType = [tooltipHtml substringWithRange:distanceTypeRange];

NSRange timeRange = NSMakeRange(slash+1, rightParanthesis-slash-1);
NSString *time = [tooltipHtml substringWithRange:timeRange];
NSString *distanceCompact = [distance stringByAppendingString:distanceType];

NSLog(@"Distance %@:", distance);
NSLog(@"Distance type %@:", distanceType);
NSLog(@"Time %@:", time);
NSLog(@"distance Compact %@:", distanceCompact);
