我有一个类似以下格式的字符串,
来电免费电话:180012345678(印度)
来电号码:+ 44-(0)123456789(英国)
英国免费电话:12345678910
会议代码:123 456 56789
如何在Objective-C
中将电话号码与此字符串分开答案 0 :(得分:3)
您可以使用NSDataDetector(https://developer.apple.com/library/ios/documentation/Foundation/Reference/NSDataDetector_Class/)
支持以下类型:
NSTextCheckingTypeOrthography = 1ULL << 0,
NSTextCheckingTypeSpelling = 1ULL << 1,
NSTextCheckingTypeGrammar = 1ULL << 2,
NSTextCheckingTypeDate = 1ULL << 3,
NSTextCheckingTypeAddress = 1ULL << 4,
NSTextCheckingTypeLink = 1ULL << 5,
NSTextCheckingTypeQuote = 1ULL << 6,
NSTextCheckingTypeDash = 1ULL << 7,
NSTextCheckingTypeReplacement = 1ULL << 8,
NSTextCheckingTypeCorrection = 1ULL << 9,
NSTextCheckingTypeRegularExpression = 1ULL << 10
NSTextCheckingTypePhoneNumber = 1ULL << 11,
NSTextCheckingTypeTransitInformation = 1ULL << 12
离。
NSError *error = NULL;
NSDataDetector *detector = [NSDataDetector dataDetectorWithTypes:NSTextCheckingTypePhoneNumber error:&error];
NSUInteger numberOfMatches = [detector numberOfMatchesInString:string options:0 range:NSMakeRange(0, [string length])];
NSArray *matches = [detector matchesInString: stringoptions:0 range:NSMakeRange(0, [string length])];
for (NSTextCheckingResult *match in matches) {
NSRange matchRange = [match range];
if ([match resultType] == NSTextCheckingTypePhoneNumber) {
NSString *phoneNumber = [match phoneNumber];
}
}
