直接上代码:
NSString*string =@"我是大大www.baidu.com咪咪咪";
NSError*error;
NSString*regulaStr =@"\\b((?:https?://|www\\d{0,3}[.]|[a-z0-9.\\-]+[.][a-z]{2,4}/)(?:[^\\s()<>]+|\\(([^\\s()<>]+|(\\([^\\s()<>]+\\)))*\\))+(?:\\(([^\\s()<>]+|(\\([^\\s()<>]+\\)))*\\)|[^\\s`!()\\[\\]{};:'\".,<>???“”‘’]))";
NSRegularExpression*regex = [NSRegularExpressionregularExpressionWithPattern:regulaStroptions:NSRegularExpressionCaseInsensitiveerror:&error];
NSLog(@"error:%@", error);
NSArray*arrayOfAllMatches = [regexmatchesInString:stringoptions:NSMatchingReportCompletionrange:NSMakeRange(0, [stringlength])];
for(NSTextCheckingResult*matchinarrayOfAllMatches)
{
NSString* substringForMatch = [stringsubstringWithRange:match.range];
NSLog(@"substringForMatch");
NSLog(@"%@", substringForMatch);
}
判断有没有加http开头：
if ([self.urlString rangeOfString:@"http"].location == NSNotFound) {
self.urlString = [@"http://" stringByAppendingString:self.urlString];
}
