最近准备接一个编辑类的app,所以就查了下相关的功能,并自己试验了下:
/**
iOS 6之前:CoreText,纯C语言,极其蛋疼
iOS 6开始:NSAttributedString,简单易用
iOS 7开始:TextKit,功能强大,简单易用
*/
具体代码:
- (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.jpeg"];
attach.bounds = CGRectMake(10, 12, 50, 50);
NSAttributedString *attachString = [NSAttributedString attributedStringWithAttachment:attach];
[string appendAttributedString:attachString];
[string appendAttributedString:[[NSAttributedString alloc] initWithString:@"789"]];
self.descTV.attributedText = string;
/**
iOS 6之前:CoreText,纯C语言,极其蛋疼
iOS 6开始:NSAttributedString,简单易用
iOS 7开始:TextKit,功能强大,简单易用
*/
}
效果图如下:
图片是我自己添加的,再加上boundsize那个方法,完全可以满足需求!
