iOS:个性化UITextView(缩进,行距,铺满)
总体来说个性化定制UITextView中的内容有两种方法:
1,从文件中读取内容到UITextView,这个个人感觉使用rtfd和rtf格式文件效果非常好。
2,使用NSAttributeString进行定制
具体方法如下:
- NSMutableParagraphStyle *paragraphStyle = [[NSMutableParagraphStyle alloc]init];
- paragraphStyle.lineHeightMultiple = 20.f;
- paragraphStyle.maximumLineHeight = 25.f;
- paragraphStyle.minimumLineHeight = 15.f;
- paragraphStyle.firstLineHeadIndent = 20.f;
- paragraphStyle.alignment = NSTextAlignmentJustified;
- NSDictionary *attributes = @{ NSFontAttributeName:[UIFont systemFontOfSize:14], NSParagraphStyleAttributeName:paragraphStyle, NSForegroundColorAttributeName:[UIColor colorWithRed:76./255. green:75./255. blue:71./255. alpha:1]
- };
- textView.attributedText = [[NSAttributedString alloc]initWithString:content attributes:attributes];
当然也可以初始化一个NSMutableAttributedString,然后向里面添加文字样式,最后将它赋给textView的AttributedText即可
- NSMutableAttributedString *atr = [[NSMutableAttributedString alloc]initWithString:detail];
- [atr addAttribute:NSFontAttributeName value:[UIFont systemFontOfSize:14] range:NSMakeRange(0, detail.length)];
- textView.attributedText = atr;
另外,对于textview中的链接样式,同样也可以定制
- NSDictionary *linkAttributes = @{NSForegroundColorAttributeName: [UIColor blueColor],
- NSUnderlineColorAttributeName: [UIColor blackColor],
- NSUnderlineStyleAttributeName: @(NSUnderlinePatternDash)};
- self.linkTextAttributes = linkAttributes;
这里只是个简单的例子,具体还有很多属性可以自行参考头文件
