一、YYLabel
强大的富文本显示功能，可根据文字的range随意添加点击事件
1 自动换行
YYLabel *yyLabel = [YYLabel new];
yyLabel.numberOfLines = 0;
创建容器
YYTextContainer *titleContarer = [YYTextContainer new];
限制宽度
titleContarer.size = CGSizeMake([UIScreen mainScreen].bounds.size.width-40,CGFLOAT_MAX);
设置富文本
NSMutableAttributedString *resultAttr = [self getAttr:title];
根据容器和文本创建布局对象
YYTextLayout *titleLayout = [YYTextLayout layoutWithContainer:titleContarer text:resultAttr];
得到文本高度
CGFloat titleLabelHeight = titleLayout.textBoundingSize.height;
设置frame
yyLabel.frame = CGRectMake(20,84,[UIScreen mainScreen].bounds.size.width-40,titleLabelHeight);
2 各种格式设置
对齐方式 这里是 两边对齐
resultAttr.alignment = NSTextAlignmentCenter;
设置行间距
resultAttr.lineSpacing = 3;
resultAttr.font = [UIFont systemFontOfSize:20];
{
NSRange range = [attributedString rangeOfString:@"it was the worst of times"];
[resultAttr setFont:[UIFont boldSystemFontOfSize:30] range:range];
}
描边
{
NSRange range =[attributedString rangeOfString:@"it was the age of wisdom"];
//文字描边（空心字）默认黑色，必须设置width
[resultAttr setStrokeColor:[UIColor orangeColor] range:range];
[resultAttr setStrokeWidth:@(2) range:range];
}
划线
{
NSRange range = [attributedString rangeOfString:@"it was the age of foolishness, it was the season of light" options:NSCaseInsensitiveSearch];
YYTextDecoration *decoration = [YYTextDecoration decorationWithStyle:YYTextLineStyleSingle
width:@(1)
color:[UIColor blueColor]];
//删除样式
[resultAttr setTextStrikethrough:decoration range:range];
//下划线
[resultAttr setTextUnderline:decoration range:range];
}
设置边框
{
NSRange range = [attributedString rangeOfString:@"这是最好的时代，这是最坏的时代" options:NSCaseInsensitiveSearch];
//边框
YYTextBorder *border = [YYTextBorder new];
border.strokeColor = [UIColor redColor];
border.strokeWidth = 4;
border.lineStyle = YYTextLineStylePatternDashDotDot;
border.cornerRadius = 1;
border.insets = UIEdgeInsetsMake(0, -2, 0, -2);
[resultAttr setTextBorder:border range:range];
}
设置阴影
{
NSRange range = [attributedString rangeOfString:@"这是智慧的时代，这是愚蠢的时代" options:NSCaseInsensitiveSearch];
//阴影
NSShadow *shadow = [[NSShadow alloc] init];
[shadow setShadowColor:[UIColor redColor]];
[shadow setShadowBlurRadius:1.0];
[shadow setShadowOffset:CGSizeMake(2, 2)];
[resultAttr setShadow:shadow range:range];
}
3 高亮显示文本 点击交互事件
{
NSRange range = [attributedString rangeOfString:@"这是希望之春，这是失望之冬" options:NSCaseInsensitiveSearch];
YYTextBorder *border = [YYTextBorder new];
border.cornerRadius = 50;
border.insets = UIEdgeInsetsMake(0, -10, 0, -10);
border.strokeWidth = 0.5;
border.strokeColor = [UIColor yellowColor];
border.lineStyle = YYTextLineStyleSingle;
[resultAttr setTextBorder:border range:range];
[resultAttr setTextBackgroundBorder:border range:range];
[resultAttr setColor:[UIColor greenColor] range:range];
YYTextBorder *highlightBorder = border.copy;
highlightBorder.strokeWidth = 0;
highlightBorder.strokeColor = [UIColor purpleColor];
highlightBorder.fillColor = [UIColor purpleColor];
YYTextHighlight *highlight = [YYTextHighlight new];
[highlight setColor:[UIColor whiteColor]];
[highlight setBackgroundBorder:highlightBorder ];
highlight.tapAction = ^(UIView *containerView, NSAttributedString *text, NSRange range, CGRect rect) {
[self alertShow:[NSString stringWithFormat:@"Tap: %@",[text.string substringWithRange:range]]];
};
[resultAttr setTextHighlight:highlight range:range];
// 点击复制
[resultAttr setTextHighlightRange:[attributedString rangeOfString:@"450351763"]
color:[UIColor greenColor]
backgroundColor:[UIColor whiteColor]
tapAction:^(UIView *containerView, NSAttributedString *text, NSRange range, CGRect rect){
UIPasteboard *pboard = [UIPasteboard generalPasteboard];
pboard.string = @"450351763";
[self alertShow:@"复制成功"];
}];
}
4 图文混排 支持各种格式包括gif
{
for (int i = 1; i<5; i++) {
NSString *path;
if(i == 4){
path = [[NSBundle mainBundle] pathForScaledResource:[NSString stringWithFormat:@"%d",i] ofType:@"gif"];
}else{
path = [[NSBundle mainBundle] pathForScaledResource:[NSString stringWithFormat:@"%d",i] ofType:@"jpg"];
}
NSData *data = [NSData dataWithContentsOfFile:path];
//修改表情大小
YYImage *image = [YYImage imageWithData:data scale:3];
image.preloadAllAnimatedImageFrames = YES;
YYAnimatedImageView *imageView = [[YYAnimatedImageView alloc] initWithImage:image];
NSMutableAttributedString *attachText = [NSMutableAttributedString attachmentStringWithContent:imageView contentMode:UIViewContentModeCenter attachmentSize:imageView.size alignToFont:[UIFont systemFontOfSize:18] alignment:YYTextVerticalAlignmentCenter];
[resultAttr appendAttributedString:attachText];
}
}
YYkit推荐pod安装方式（我使用的是 pod 'YYKit', '~> 1.0.9' 最新版本)
以下为全部代码贴到项目中可以直接运行查看效果
@interfaceViewController2()
@end
