搞个图文混排，发现网上的都比较复杂，我就想简单的使用一下textview，没有必要用coreText等复杂的东西，上代码啦
NSString *textStr = @"首单红包规则\n1.每个淘宝账号每天可领取一次\n2.首单礼金金额随机，以实际领取的金额为准\n3.礼金当日有效，请及时使用\n4.领取后建议当日使用，否则以后领取的金额会变小\n5.使用礼金的订单发生退款，礼金作废\n";
self.view.backgroundColor = SepratorLineColor;
UITextView * textview = [[UITextView alloc] init]; textview.frame = CGRectMake(0, 0, ScreenWidth, 600); [self.view addSubview:textview]; [textview mas_makeConstraints:^(MASConstraintMaker *make) { make.left.right.bottom.mas_equalTo(0); make.top.mas_equalTo(WidthRate(15)); }]; textview.font = SYSTEM_FONT(13); textview.editable = false; textview.textColor = textColor_333333;
//调整文字和间距 NSMutableParagraphStyle *MParaStyle = [[NSMutableParagraphStyle alloc] init]; MParaStyle.paragraphSpacing = 11; // 段落间距离 MParaStyle.firstLineHeadIndent = 15; NSMutableAttributedString *att = [[NSMutableAttributedString alloc] initWithString:textStr]; [att addAttribute:NSForegroundColorAttributeName value:[UIColor blackColor] range:NSMakeRange(0, 6)]; [att addAttribute:NSFontAttributeName value:BoldSYSTEM_FONT(16) range:NSMakeRange(0, 6)]; [att addAttribute:NSParagraphStyleAttributeName value:MParaStyle range:NSMakeRange(0, [textStr length])]; //添加分割线图片
NSTextAttachment *attachmentLine = [[NSTextAttachment alloc] init];
attachmentLine.image = [YFDTools createImageWithColor:SepratorLineColor frame:CGRectMake(0, 0, ScreenWidth, WidthRate(15))];
NSMutableAttributedString *attachmentLineString = [[NSMutableAttributedString alloc] initWithAttributedString:[NSAttributedString attributedStringWithAttachment:attachmentLine]]; attachmentLine.bounds = CGRectMake(0, -0, ScreenWidth, WidthRate(15)); [att appendAttributedString:attachmentLineString];
NSString *SecondtextStr = @"\n\n如何使用\n第一步:领取首单礼金（禁拍）\n"; //调整文字和间距 NSMutableParagraphStyle *SecondMParaStyle = [[NSMutableParagraphStyle alloc] init]; SecondMParaStyle.paragraphSpacing = 11; // 段落间距离 SecondMParaStyle.firstLineHeadIndent = 15; NSMutableAttributedString *secondAtt = [[NSMutableAttributedString alloc] initWithString:SecondtextStr]; [secondAtt addAttribute:NSForegroundColorAttributeName value:[UIColor blackColor] range:NSMakeRange(0, 6)]; [secondAtt addAttribute:NSFontAttributeName value:BoldSYSTEM_FONT(16) range:NSMakeRange(0, 4)]; [secondAtt addAttribute:NSParagraphStyleAttributeName value:SecondMParaStyle range:NSMakeRange(0, [SecondtextStr length])]; [att appendAttributedString:secondAtt];
NSTextAttachment *attachment = [[NSTextAttachment alloc] init]; attachment.image = [UIImage imageNamed:@"bg_explain1"];
NSMutableAttributedString *attachmentString = [[NSMutableAttributedString alloc] initWithAttributedString:[NSAttributedString attributedStringWithAttachment:attachment]]; attachment.bounds = CGRectMake(0, -200, ScreenWidth, WidthRate(235)); [att appendAttributedString:attachmentString];
NSString *ThirdtextStr = @"\n第二步：返回活动页面选择满意的商品下单\n";
//调整文字和间距 NSMutableParagraphStyle *thirdMParaStyle = [[NSMutableParagraphStyle alloc] init]; thirdMParaStyle.paragraphSpacing = 11; // 段落间距离 thirdMParaStyle.firstLineHeadIndent = 15; NSMutableAttributedString *thirdAtt = [[NSMutableAttributedString alloc] initWithString:ThirdtextStr]; [thirdAtt addAttribute:NSParagraphStyleAttributeName value:thirdMParaStyle range:NSMakeRange(0, [ThirdtextStr length])]; [att appendAttributedString:thirdAtt];
NSTextAttachment *attachment1 = [[NSTextAttachment alloc] init];
attachment1.image = [UIImage imageNamed:@"bg_explain2"];
NSMutableAttributedString *attachmentString1 = (NSMutableAttributedString *)[NSAttributedString attributedStringWithAttachment:attachment1];
//只是简单的计算的高度 CGFloat newH = 368*279/346; attachment1.bounds = CGRectMake(0, 0, WidthRate(368), WidthRate(newH));
[att appendAttributedString:attachmentString1]; textview.attributedText = att;
实现效果
