一、概念

/**

1.添加图片效果图

2.富文本添加图片代码

3.富文本总结

4.直接拷贝代码就可以用

二、添加图片效果图

富文本添加图片-1

三、富文本添加图片代码

// ViewController.m

// 测试富文本

//

// Copyright © 2018年石虎. All rights reserved.

#import "ViewController.h"

@interface ViewController ()

@end

@implementation ViewController

- (void)viewDidLoad {

[super viewDidLoad];

//1.设置标签

UILabel *titleLabel = [[UILabel alloc]initWithFrame:CGRectMake(0, 0, self.view.frame.size.width, self.view.frame.size.height)]; titleLabel.backgroundColor = [UIColor yellowColor];

titleLabel.text = @"石虎祝所有人步步高升,成为技术大神";

titleLabel.textColor = [UIColor redColor];

[self.view addSubview:titleLabel];

//2.初始化富文本对象

NSMutableAttributedString *attributedString = [[NSMutableAttributedStringalloc] initWithString:titleLabel.text];

//2.1修改富文本中的不同文字的样式

[attributedString addAttribute:NSForegroundColorAttributeName value:[UIColor blueColor] range:NSMakeRange(0, 5)];//字体颜色

[attributedString addAttribute:NSForegroundColorAttributeName value:[UIColor purpleColor] range:NSMakeRange(7, 6)];//字体颜色

[attributedString addAttribute:NSFontAttributeName value:[UIFont systemFontOfSize:22] range:NSMakeRange(0, 6)];//字体大小

//3.初始化NSTextAttachment对象

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

attchment.bounds = CGRectMake(0, 0, 40, 40);//设置frame

attchment.image = [UIImage imageNamed:@"release_homework"];//设置图片

//4.创建带有图片的富文本

NSAttributedString *string = [NSAttributedString attributedStringWithAttachment:(NSTextAttachment *)(attchment)];

[attributedString insertAttributedString:string atIndex:0];//插入到第几个下标

[attributedString appendAttributedString:string]; //添加到尾部

//5.用label的attributedText属性来使用富文本

titleLabel.attributedText = attributedString;

}

@end

四、富文本总结

这是富文本的所有属性

属性Name干啥的类型

NSFontAttributeName字号UIFont 默认12

NSParagraphStyleAttributeName段落样式NSParagraphStyle

NSForegroundColorAttributeName前景色UIColor

NSBackgroundColorAttributeName背景色UIColor

NSObliquenessAttributeName字体倾斜NSNumber

NSExpansionAttributeName字体加粗NSNumber 比例 0就是不变 1增加一倍

NSKernAttributeName字间距CGFloat

NSUnderlineStyleAttributeName下划线1或0

NSUnderlineColorAttributeName下划线颜色UIColor

NSStrikethroughStyleAttributeName删除线1或0

NSStrikethroughColorAttributeName删除线颜色UIColor

NSStrokeColorAttributeNamesame as ForegroundColorUIColor

NSStrokeWidthAttributeName字体描边CGFloat

NSLigatureAttributeName连笔字没看出效果1或0

NSShadowAttributeName阴影NSShawdow

NSTextEffectAttributeName设置文本特殊效果,目前只有图版印刷效果可用NSString

NSAttachmentAttributeName设置文本附件,常用插入图片NSTextAttachment

NSLinkAttributeName链接NSURL (preferred) or NSString

NSBaselineOffsetAttributeName基准线偏移NSNumber

NSWritingDirectionAttributeName文字方向分别代表不同的文字出现方向等等，我想你一定用不到它 - -@[@(1),@(2)]

NSVerticalGlyphFormAttributeName水平或者竖直文本在iOS没卵用，不支持竖版1竖直 0水平

谢谢!!!
