很多开发工具都有支持正则表达式的内容,IOS也不例外,在IOS中NSRegularExpression类就是一个专门来处理正则表达式的类。...一、初始化方法 初始化NSRegularExpression的方法有两种,一个init方法和一个类方法。...其作用基本是一样的 + (NSRegularExpression *)regularExpressionWithPattern:(NSString *)pattern options:(NSRegularExpressionOptions...usingBlock:(void (^)(NSTextCheckingResult *result, NSMatchingFlags flags, BOOL *stop))block; 使用举例: NSRegularExpression... * regex = [[NSRegularExpression alloc]initWithPattern:@"[a-z]" options:NSRegularExpressionCaseInsensitive
NSString * pattern = @"\\[[a-zA-Z0-9\\u4e00-\\u9fa5]+\\]"; NSError *error = nil; NSRegularExpression...*re = [NSRegularExpression regularExpressionWithPattern:pattern options:NSRegularExpressionCaseInsensitive
NSRegularExpression(pattern: pattern, options: NSRegularExpression.Options.caseInsensitive) else {
"; NSError *error = NULL; NSRegularExpression *regx = [NSRegularExpression regularExpressionWithPattern
areaFlag) { return false; } NSRegularExpression *regularExpression; NSUInteger numberofMatch...if (year %4 ==0 || (year 0 ==0 && year %4 ==0)) { regularExpression = [[NSRegularExpression...error:nil];//测试出生日期的合法性 }else { regularExpression = [[NSRegularExpression...if (year %4 ==0 || (year 0 ==0 && year %4 ==0)) { regularExpression = [[NSRegularExpression...error:nil];//测试出生日期的合法性 }else { regularExpression = [[NSRegularExpression
通过正则表达式来匹配字符串 NSString*regex_emoji =@"\\[[a-zA-Z0-9\\/\\u4e00-\\u9fa5]+\\]";//匹配表情 NSError*error =nil; NSRegularExpression...*re = [NSRegularExpression regularExpressionWithPattern:regex_emoji options:NSRegularExpressionCaseInsensitive...与以上方法主要不同点在于正则表达式: //2、匹配字符串 NSError *error = nil; NSRegularExpression*re = [NSRegularExpression
下面介绍一下 NSRegularExpression ?...NSRegularExpression 位于 Foundation 框架中,主要作用相当与检索条件判断,但是其强大方便的功能是以晦涩的语法为牺牲的。...NSRegularExpression 的相关方法 # 初始化方法 + (nullable NSRegularExpression *)regularExpressionWithPattern:...*regex = [NSRegularExpression regularExpressionWithPattern:@"\\d{3}-\\d{8}|\\d{3}-\\d{7}|\\d{4}-\\d{...参考文章 iOS中的谓词(NSPredicate)使用 正则表达式 NSRegularExpression
// 1.创建正则表达式,[0-9]:表示‘0’到‘9’的字符的集合 NSString *pattern = @"[0-9]"; // 1.1将正则表达式设置为OC规则 NSRegularExpression...*regular = [[NSRegularExpression alloc] initWithPattern:pattern options:NSRegularExpressionCaseInsensitive

/正则表达式 NSString * pattern = @"\\[[a-zA-Z0-9\\u4e00-\\u9fa5]+\\]"; NSError *error = nil; NSRegularExpression...* re = [NSRegularExpression regularExpressionWithPattern:pattern options:NSRegularExpressionCaseInsensitive
符合要求的字符串及参数 数组 */ + (NSArray *)matchString:(NSString *)string toRegexString:(NSString *)regexStr { NSRegularExpression...*regex = [NSRegularExpression regularExpressionWithPattern:regexStr options:NSRegularExpressionCaseInsensitive
= NSNotFound) { NSLog(@"range :%@", [searchText substringWithRange:range]); } 3.正则表达式类(NSRegularExpression...) NSString *searchText = @"you want to match"; NSError *error = NULL; NSRegularExpression...*regex = [NSRegularExpression regularExpressionWithPattern:@"^[0-9]+$" options:NSRegularExpressionCaseInsensitive
client_port=(\\w+) NSRegularExpression *regex = [NSRegularExpression regularExpressionWithPattern
//正则替换 NSRegularExpression *regex = [NSRegularExpression regularExpressionWithPattern:@"(]+esrc
NSRegularExpression(pattern: pattern, options: []) if let match = regex?.
通过iOS中的NSRegularExpression这个类就可以帮助我们实现这个。 下面先来介绍一下正则表达式的基本语法。
