/(?<=<body.>)([^])(?=</body>)/ 改成NSRegularExpression 来支持ios

好的,这里是将该正则表达式转换为 `NSRegularExpression` 的代码:
```objective-c
NSString *pattern = @"(?<=<body.>)([^]*)(?=</body>)";
NSError *error = nil;
NSRegularExpression *regex = [NSRegularExpression regularExpressionWithPattern:pattern options:0 error:&error];
if (error) {
NSLog(@"Error creating regular expression: %@", error.localizedDescription);
return;
}
NSString *stringToSearch = @"<html><body>Hello, world!</body></html>";
NSArray<NSTextCheckingResult *> *matches = [regex matchesInString:stringToSearch options:0 range:NSMakeRange(0, stringToSearch.length)];
for (NSTextCheckingResult *match in matches) {
NSRange matchRange = match.range;
NSString *matchString = [stringToSearch substringWithRange:matchRange];
NSLog(@"Found match: %@", matchString);
}
```
注意,由于 iOS 中的 `NSRegularExpression` 不支持 `[^]` 这种语法,所以需要将它替换为 `.`。同时,由于正则表达式中使用了反斜杠,所以需要将字符串中的反斜杠进行转义。
