我使用TTTAttributedLabel检测我的超文本链接，这样我可以让他们点击。 我的代码不能正常工作，并链接无法点击。 事实上，一切都点击。 我只想网址为不可点击。
这里是正则表达式：
static NSRegularExpression *websiteRegularExpression;
static inline NSRegularExpression * WebsiteRegularExpression() {
if (!websiteRegularExpression) {
websiteRegularExpression = [[NSRegularExpression alloc] initWithPattern:@"\b(https?|ftp|file)://[-A-Z0-9+&@#/%?=~_|!:,.;]*[A-Z0-9+&@#/%=~_|]"
options:NSRegularExpressionCaseInsensitive
error:nil];
}
return websiteRegularExpression;
}
下面是执行
-(void)setBodyText
{
__block NSRegularExpression *regexp = nil;
NSString* labelText = [[message valueForKey:@"body"]gtm_stringByUnescapingFromHTML]; //@"http://www.google.com is a cool website";
[self.bodyLabel setText:labelText afterInheritingLabelAttributesAndConfiguringWithBlock:^NSAttributedString *(NSMutableAttributedString *mutableAttributedString) {
NSRange stringRange = NSMakeRange(0, [mutableAttributedString length]);
/* regexp = WebsiteRegularExpression ();
NSRange nameRange = [regexp rangeOfFirstMatchInString:[mutableAttributedString string] options:0 range:stringRange];
UIFont *boldSystemFont = [UIFont boldSystemFontOfSize:18.0];
CTFontRef boldFont = CTFontCreateWithName((CFStringRef)boldSystemFont.fontName, boldSystemFont.pointSize, NULL);
if (boldFont) {
[mutableAttributedString addAttribute:(NSString *)kCTFontAttributeName value:(id)boldFont range:nameRange];
CFRelease(boldFont);
}
if (nameRange.location != NSNotFound)
[mutableAttributedString replaceCharactersInRange:nameRange withString:[[[mutableAttributedString string] substringWithRange:nameRange] uppercaseString]];
return mutableAttributedString;
*/
regexp = WebsiteRegularExpression();
[regexp enumerateMatchesInString:[mutableAttributedString string] options:0 range:stringRange usingBlock:^(NSTextCheckingResult *result, NSMatchingFlags flags, BOOL *stop) {
UIFont *italicSystemFont = [UIFont italicSystemFontOfSize:18.0];
CTFontRef italicFont = CTFontCreateWithName((CFStringRef)italicSystemFont.fontName, italicSystemFont.pointSize, NULL);
if (italicFont) {
[mutableAttributedString addAttribute:(NSString *)kCTFontAttributeName value:(id)italicFont range:result.range];
CFRelease(italicFont);
[mutableAttributedString addAttribute:(NSString*)kCTForegroundColorAttributeName value:(id)[[UIColor grayColor] CGColor] range:result.range];
}
}];
return mutableAttributedString;
}];
regexp = WebsiteRegularExpression();
NSRange linkRange = [regexp rangeOfFirstMatchInString:labelText options:0 range:NSMakeRange(0, [labelText length])];
NSURL *url = [NSURL URLWithString:@"http://www.google.com"];
[self.bodyLabel addLinkToURL:url withRange:linkRange];
[Utils alignLabelWithTop:bodyLabel];
}
