一、YYLabel
強大的富文本顯示功能，可根據文字的range隨意添加點擊事件
1 自動換行
YYLabel? *yyLabel = [YYLabel new];
yyLabel.numberOfLines = 0;
創建容器
YYTextContainer *titleContarer = [YYTextContainer new];
限制寬度
titleContarer.size = CGSizeMake([UIScreen mainScreen].bounds.size.width-40,CGFLOAT_MAX);
設置富文本
NSMutableAttributedString? *resultAttr = [self getAttr:title];
根據容器和文本創建布局對象
YYTextLayout *titleLayout = [YYTextLayout layoutWithContainer:titleContarer text:resultAttr];
得到文本高度
CGFloat titleLabelHeight = titleLayout.textBoundingSize.height;
設置frame
yyLabel.frame = CGRectMake(20,84,[UIScreen mainScreen].bounds.size.width-40,titleLabelHeight);
2 各種格式設置
對齊方式 這里是 兩邊對齊
resultAttr.alignment = NSTextAlignmentCenter;
設置行間距
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];
}
描邊
{
NSRange range =[attributedString rangeOfString:@"it was the age of wisdom"];
//文字描邊（空心字）默認黑色，必須設置width
[resultAttr setStrokeColor:[UIColor orangeColor] range:range];
[resultAttr setStrokeWidth:@(2) range:range];
}
劃線
{
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]];
//刪除樣式
[resultAttr setTextStrikethrough:decoration range:range];
//下劃線
[resultAttr setTextUnderline:decoration range:range];
}
設置邊框
{
NSRange range = [attributedString rangeOfString:@"這是最好的時代，這是最壞的時代" options:NSCaseInsensitiveSearch];
//邊框
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];
}
設置陰影
{
NSRange range = [attributedString rangeOfString:@"這是智慧的時代，這是愚蠢的時代" options:NSCaseInsensitiveSearch];
//陰影
NSShadow *shadow = [[NSShadow alloc] init];
[shadow setShadowColor:[UIColor redColor]];
[shadow setShadowBlurRadius:1.0];
[shadow setShadowOffset:CGSizeMake(2, 2)];
[resultAttr setShadow:shadow range:range];
}
3 高亮顯示文本 點擊交互事件
{
NSRange range = [attributedString rangeOfString:@"這是希望之春，這是失望之冬" 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];
// 點擊復制
[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:@"復制成功"];
}];
}
4 圖文混排 支持各種格式包括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推薦pod安裝方式（我使用的是 ?pod 'YYKit', '~> 1.0.9' 最新版本)
以下為全部代碼貼到項目中可以直接運行查看效果
