- (void)viewDidLoad {
[super viewDidLoad];
NSString *originalString = @"非汉字 !@##@¥、字母 adafsa、#@#@#¥数字 空 格121223123¥¥#";
NSString *resultString = [self filterCharactor:originalString withRegex:@"[^a-zA-Z0-9\u4e00-\u9fa5\\s+]"];
NSLog(@"%@", resultString);
}
// 过滤字符串中的非汉字、字母、数字
- (NSString *)filterCharactor:(NSString *)string withRegex:(NSString *)regexStr {
NSString *filterText = string;
NSError *error = NULL;
NSRegularExpression *regex = [NSRegularExpression regularExpressionWithPattern:regexStr options:NSRegularExpressionCaseInsensitive error:&error];
NSString *result = [regex stringByReplacingMatchesInString:filterText
options:NSMatchingReportCompletion
range:NSMakeRange(0, filterText.length)
withTemplate:@""];
return result;
}
