如何使用正则表达式在iOS中获取匹配？

#import <Foundation/Foundation.h>

int main(int argc, const char * argv[]) {
    @autoreleasepool {
        NSString *inputString = @"Hello, my email is example@example.com";
        NSString *pattern = @"\\b[A-Za-z0-9._%+-]+@[A-Za-z0-9.-]+\\.[A-Za-z]{2,}\\b";
        
        NSError *error = nil;
        NSRegularExpression *regex = [NSRegularExpression regularExpressionWithPattern:pattern options:0 error:&error];
        
        if (regex) {
            NSArray<NSTextCheckingResult *> *matches = [regex matchesInString:inputString options:0 range:NSMakeRange(0, inputString.length)];
            
            for (NSTextCheckingResult *match in matches) {
                NSRange matchRange = [match range];
                NSString *matchedString = [inputString substringWithRange:matchRange];
                NSLog(@"Matched string: %@", matchedString);
            }
        } else {
            NSLog(@"Error creating regex: %@", error);
        }
    }
    return 0;
}
