UITextView 识别链接、电话、地址

UITextView 识别链接、电话、地址

识别一段文字中是否包含链接/电话/地址我们只需要设置UITextView这个属性就OK了

self.textView.dataDetectorTypes = UIDataDetectorTypePhoneNumber;

self.textView.editable = NO;编辑模式设为NO，才可以开启识别模式

type枚举类型

typedef NS_OPTIONS(NSUInteger, UIDataDetectorTypes) {
    UIDataDetectorTypePhoneNumber                                        = 1 << 0, // Phone number detection
    UIDataDetectorTypeLink                                               = 1 << 1, // URL detection
    UIDataDetectorTypeAddress NS_ENUM_AVAILABLE_IOS(4_0)                 = 1 << 2, // Street address detection
    UIDataDetectorTypeCalendarEvent NS_ENUM_AVAILABLE_IOS(4_0)           = 1 << 3, // Event detection
    UIDataDetectorTypeShipmentTrackingNumber NS_ENUM_AVAILABLE_IOS(10_0) = 1 << 4, // Shipment tracking number detection
    UIDataDetectorTypeFlightNumber NS_ENUM_AVAILABLE_IOS(10_0)           = 1 << 5, // Flight number detection
    UIDataDetectorTypeLookupSuggestion NS_ENUM_AVAILABLE_IOS(10_0)       = 1 << 6, // Information users may want to look up
    UIDataDetectorTypeNone          = 0,               // Disable detection
    UIDataDetectorTypeAll           = NSUIntegerMax    // Enable all types, including types that may be added later
} __TVOS_PROHIBITED;

如果我们想判断一个stirng里面是否包含 电话号码 URL 地址 日期 还在为写一正则而苦恼😞?

NSDataDetector 可以轻松帮我们搞定

使用:

NSString * string = @"欢迎访问http://www.111cn.net，https://111cn.net\n以及ftp://111cn.net";
NSError * error = nil;
NSDataDetector * detector = [NSDataDetector dataDetectorWithTypes:NSTextCheckingTypePhoneNumber| NSTextCheckingTypeLink  error:&error];
NSUInteger numberOfMatches = [detector numberOfMatchesInString:string                                                  options:0                                                         range:NSMakeRange(0, [string length])];

matches(in:options:range:)的用法:
查看一共有多少匹配项.还有matches(in:options:range:)和firstMatch(in:options:range:)

NSString * string = @"欢迎访问http://www.jianshu.com/users/72ee5da886ff/latest_articles. 咱的电话是012-1304445928.ps:电话随便写的哟.今天是2016-10-25,天气(weather)不错";
    
NSString * string = @"欢迎访问http://www.jianshu.com/users/72ee5da886ff/latest_articles. 咱的电话是012-1304445928.ps:电话随便写的哟.今天是2016-10-25,天气(weather)不错";
NSError * error = nil;
NSDataDetector * detector = [NSDataDetector dataDetectorWithTypes:NSTextCheckingTypeLink|NSTextCheckingTypePhoneNumber error:&error];
    
NSArray *matches = [detector matchesInString:string
                                         options:0
                                           range:NSMakeRange(0, [string length])];
for (NSTextCheckingResult *match in matches) {
        NSRange matchRange = [match range];
        if ([match resultType] == NSTextCheckingTypeLink) {
            NSURL *url = [match URL];
            NSLog(@"url:%@", url);
        } else if ([match resultType] == NSTextCheckingTypePhoneNumber) {
            NSString *phoneNumber = [match phoneNumber];
            NSLog(@"phoneNumber:%@", phoneNumber);
        }
}

块用法

NSString * string = @"欢迎访问http://www.jianshu.com/users/72ee5da886ff/latest_articles. 咱的电话是012-1304445928.ps:电话随便写的哟.今天是2016-10-25,天气(weather)不错";
    NSError * error = nil;
    NSDataDetector * detector = [NSDataDetector dataDetectorWithTypes:NSTextCheckingTypeLink|NSTextCheckingTypePhoneNumber error:&error];
    
    
    __block NSUInteger count = 0;
    [detector enumerateMatchesInString:string options:0 range:NSMakeRange(0, [string length]) usingBlock:^(NSTextCheckingResult * _Nullable match, NSMatchingFlags flags, BOOL * _Nonnull stop) {
        
        NSLog(@"flag:%lu",(unsigned long)flags);
        NSRange matchRange = [match range];
        
        if ([match resultType] == NSTextCheckingTypeLink) {
            NSURL *url = [match URL];
            NSLog(@"url:%@", url);
        }
        if (count == 0) *stop = YES;
        
        if ([match resultType] == NSTextCheckingTypePhoneNumber) {
            NSString *phoneNumber = [match phoneNumber];
            NSLog(@"phoneNumber:%@", phoneNumber);
        }
        
    }];
