TTTAttributedLabel继承自UILabel,很方便基于现有代码进行修改,Star超过6K+,作者一直有更新,今天用了一下作点笔记。
//设置高亮颜色
label.highlightedTextColor = [UIColor greenColor];
//检测url
label.enabledTextCheckingTypes = NSTextCheckingTypeLink;
//对齐方式
label.verticalAlignment = TTTAttributedLabelVerticalAlignmentCenter;
//行间距
label.lineSpacing = 8;
//设置阴影
label.shadowColor = [UIColor grayColor];
label.delegate = self; // Delegate
//NO 不显示下划线
label.linkAttributes = [NSDictionary dictionaryWithObject:[NSNumber numberWithBool:NO] forKey:(NSString *)kCTUnderlineStyleAttributeName];
NSString *text = @"冷清风 赞了 王战 的说说";
[label setText:text afterInheritingLabelAttributesAndConfiguringWithBlock:^ NSMutableAttributedString *(NSMutableAttributedString*mutableAttributedString)
{
//设置可点击文字的范围
NSRange boldRange = [[mutableAttributedString string] rangeOfString:@"冷清风" options:NSCaseInsensitiveSearch];
//设定可点击文字的的大小
UIFont *boldSystemFont = [UIFont boldSystemFontOfSize:16];
CTFontRef font = CTFontCreateWithName((__bridge CFStringRef)boldSystemFont.fontName, boldSystemFont.pointSize, NULL);
if (font) {
//设置可点击文本的大小
[mutableAttributedString addAttribute:(NSString *)kCTFontAttributeName value:(__bridge id)font range:boldRange];
//设置可点击文本的颜色
[mutableAttributedString addAttribute:(NSString*)kCTForegroundColorAttributeName value:(id)[[UIColor blueColor] CGColor] range:boldRange];
CFRelease(font);
}
return mutableAttributedString;
}];
//正则
NSRegularExpression *regexp = NameRegularExpression();
NSRange linkRange = [regexp rangeOfFirstMatchInString:text options:0 range:NSMakeRange(0, 3)];
NSURL *url = [NSURL URLWithString:[NSString stringWithFormat:@"http://www.exiucai.com/"]];
//设置链接的url
[label addLinkToURL:url withRange:linkRange];
