yytextview多种格式_iOS YYText的使用笔记一(YYTextView图文编辑器)

YYText是强大的YYKit的一部分可以单独下载

Powerful text framework for iOS to display and edit rich text. (It's a component ofYYKit)

集成的时候建议使用cocopod管理

1.里面主要两个控件：

YYTextView 和 YYLabel

现在主要是YYTextview的简单使用

YYText主要是NSMutableAttributedString来处理富文本他的内部实现可以自己去深究。

简单的图文并排，使用NSMutableAttributedString创建一个对象然后 appendAttributesString来拼接文字和图片(占位)

直接上代码：

// TextAndImageTextViewVC.h

// YYTextDemo

// Created by linpeng on 16/3/13.

#import

@interface TextAndImageTextViewVC : UIViewController

@end

// TextAndImageTextViewVC.m

// YYTextDemo

// Created by linpeng on 16/3/13.

#import "TextAndImageTextViewVC.h"

#import "YYText.h"

#import "UIView+YYAdd.h"

#import "YYTextView.h"

#import "YYImage.h"

#import "NSBundle+YYAdd.h"

#import "NSString+YYAdd.h"

@interface TextAndImageTextViewVC ()

@end

YYTextView *textView;

@implementation TextAndImageTextViewVC

- (void)viewDidLoad {

[super viewDidLoad];

[self.view setBackgroundColor:[UIColor whiteColor]];

textView = [[YYTextView alloc] initWithFrame:CGRectMake(0, 0, 0, 0)];

textView.userInteractionEnabled = YES;

textView.textVerticalAlignment = YYTextVerticalAlignmentTop;

textView.size = CGSizeMake(self.view.frame.size.width, self.view.frame.size.height);

//创建最主要的attribute文本

NSMutableAttributedString *contentText = [NSMutableAttributedString new];

UIFont *font = [UIFont systemFontOfSize:16];

//图片资源

YYImage *image = [YYImage imageNamed:@"demo.jpg"];

image.preloadAllAnimatedImageFrames = YES;

//添加文本+图片

[contentText appendAttributedString:[[NSAttributedString alloc] initWithString:@"这是第一站图片" attributes:nil]];

{

YYAnimatedImageView *imageView = [[YYAnimatedImageView alloc] initWithImage:image];

imageView.frame = CGRectMake(0, 0, textView.width - 10, textView.width/image.size.width*image.size.height);

NSMutableAttributedString *attachText = [NSMutableAttributedString yy_attachmentStringWithContent:imageView contentMode:UIViewContentModeScaleAspectFit attachmentSize:imageView.size alignToFont:font alignment:YYTextVerticalAlignmentCenter];

[contentText appendAttributedString:attachText];

}

//添加文本+图片

[contentText appendAttributedString:[[NSAttributedString alloc] initWithString:@"\n 接下来是第二张" attributes:nil]];

{

YYAnimatedImageView *imageView2 = [[YYAnimatedImageView alloc] initWithImage:image];

imageView2.frame = CGRectMake(0, 0, textView.width - 10, textView.width/image.size.width*image.size.height);

NSMutableAttributedString *attachText2 = [NSMutableAttributedString yy_attachmentStringWithContent:imageView2 contentMode:UIViewContentModeScaleAspectFit attachmentSize:imageView2.size alignToFont:font alignment:YYTextVerticalAlignmentCenter];

[contentText appendAttributedString:attachText2];

}

textView.attributedText = contentText;

[self.view addSubview:textView];

//获取图片资源

NSArray *attachments = textView.textLayout.attachments;

for(YYTextAttachment *attachment in attachments)

{

YYAnimatedImageView *imageView = attachment.content;

YYImage *image = (YYImage *)imageView.image;

NSLog(@"获取到图片:%@",image);

}
