    本人工作之余写的一个红海新闻应用,MVC架构设计,项目虽然很小,但是五脏俱全。下面请先看看项目结构吧:

    项目结构如图 

    项目效果图 

    新闻首页就不多说,是TableView实现,但是详情页面是富文本实现,具体代码如下: 

    * //进行NSTextAttachment的创建 

    NSTextAttachment * attach = [[NSTextAttachment alloc]init]; 

    //设置显示的图片 

    attach.image =self.model.image; 

    //设置尺寸 

    attach.bounds = CGRectMake(10, 10, [UIScreen mainScreen].bounds.size.width-20, self.model.ImageHeight); 

    //创建文本NSAttributedString对象 

    NSMutableAttributedString * attri = [[NSMutableAttributedString alloc]initWithString:self.model.content];* 

    NSRange ragen = NSMakeRange(0, self.model.content.length);

    [attri addAttribute:NSFontAttributeName

                          value:[UIFont systemFontOfSize:13.0]

                          range:ragen];

    [attri addAttribute:NSUnderlineStyleAttributeName

                  value:@(NSUnderlineStyleSingle)

                  range:ragen];

    NSMutableParagraphStyle *paragraphStyle = [[NSMutableParagraphStyle alloc] init];

    paragraphStyle.lineSpacing = 10;// 字体的行间距

    paragraphStyle.firstLineHeadIndent = 40.0f;//首行缩进

    paragraphStyle.paragraphSpacing = 15;//段与段之间的间距

    paragraphStyle.paragraphSpacingBefore = 40.0f;//段首行空白空间

    [attri addAttribute:NSParagraphStyleAttributeName value:paragraphStyle range:ragen];

    //将NSTextAttachment映射为NSAttributedString对象

    NSMutableAttributedString * att = [[NSMutableAttributedString alloc]initWithAttributedString:[NSAttributedString attributedStringWithAttachment:attach]];

    //将图片插入NSAttributedString中

    [attri insertAttributedString:att atIndex:100];

    UITextView * label = [[UITextView alloc]init];

    label.editable = NO;

    label.backgroundColor = [UIColor clearColor];

    label.attributedText = attri;

    [self.view addSubview:label];

    [label mas_makeConstraints:^(MASConstraintMaker *make) {

        make.top.equalTo(@(0));

        make.left.equalTo(@(10));

        make.bottom.equalTo(@(-10));

        make.right.equalTo(@(-10));

    }];*

    这是今年第一次写,希望以后多写写,现在把代码地址贴上:https://gitee.com/baishiyun/red_sea_news_app ,初学者可以看看,大牛勿喷!谢谢大家,觉得不错的请给一个星星吧!您的支持就是我前进的动力,以后会写更多文章供需要的朋友学习!谢谢!
