与CoreText,textKit的区别

代码示例及注释讲解
- (void)setupTextView
{
// 富文本技术:
// 1.图文混排
// 2.随意修改文字样式
// self.textView.text = @"哈哈4365746875";
// self.textView.textColor = [UIColor blueColor];
NSMutableAttributedString *string = [[NSMutableAttributedString alloc] initWithString:@"哈哈123456"];
// 设置“哈哈”为蓝色
[string addAttribute:NSForegroundColorAttributeName value:[UIColor blueColor] range:NSMakeRange(0, 2)];
[string addAttribute:NSFontAttributeName value:[UIFont systemFontOfSize:30] range:NSMakeRange(0, 2)];
[string addAttribute:NSBackgroundColorAttributeName value:[UIColor redColor] range:NSMakeRange(0, 2)];
// 设置“456”为红色
[string addAttribute:NSForegroundColorAttributeName value:[UIColor redColor] range:NSMakeRange(6, 2)];
[string addAttribute:NSFontAttributeName value:[UIFont boldSystemFontOfSize:24] range:NSMakeRange(6, 2)];
[string addAttribute:NSUnderlineStyleAttributeName value:@(NSUnderlineStyleSingle) range:NSMakeRange(6, 2)];
// 创建图片图片附件
NSTextAttachment *attach = [[NSTextAttachment alloc] init];
attach.image = [UIImage imageNamed:@"d_aini"];
attach.bounds = CGRectMake(0, 0, 15, 15);
NSAttributedString *attachString = [NSAttributedString attributedStringWithAttachment:attach];
[string appendAttributedString:attachString];
[string appendAttributedString:[[NSAttributedString alloc] initWithString:@"789"]];
self.textView.attributedText = string;
