引言
应用场景：使用原生视图UILabel显示服务端返回的带有HTML标签的内容
I 、 html转换为富文本
NSString *html = @"<p style='color:green'>博客<span style='color:#e83c36;'><a>https://kunnan.blog.csdn.net/<a/></span><br/>微信公众号：<span style='color:red'>iOS逆向</span><br/>“订阅”一次 ，享受终身服务的快乐。</br><span style='color:red'>专注《iOS应用逆向与安全》</span>(包括iOS基础)</p>";
NSAttributedString *attStr = [[NSAttributedString alloc] initWithData:[html dataUsingEncoding:NSUnicodeStringEncoding] options:@{NSDocumentTypeDocumentAttribute: NSHTMLTextDocumentType} documentAttributes:nil error:nil];
II、富文本转换为html
- (void)NSAttributedStringtohtmlWith:(NSAttributedString*)attStr{
NSDictionary *dic = @{NSDocumentTypeDocumentAttribute:NSHTMLTextDocumentType,NSCharacterEncodingDocumentAttribute:@(NSUnicodeStringEncoding)};
NSData *data = [attStr dataFromRange:NSMakeRange(0, attStr.length) documentAttributes:dic error:nil];
NSString *str = [[NSString alloc] initWithData:data encoding:NSUnicodeStringEncoding];
NSLog(@"NSAttributedStringtohtmlWith:%@",str);
[self gotoAXWebViewControllerWithHtmlstr:str];
}
III、加载本地HTML文件
1、文章：kunnan.blog.csdn.net/article/det… 2、原理：`使用[_webView loadHTMLString:html baseURL:baseURL]; 进行代码加载
NSURL *baseURL = [NSURL fileURLWithPath:[[NSBundle mainBundle] bundlePath]];
[self loadHTMLString:_HTMLString baseURL:_baseURL];
`
- 例子
#import <AXWebViewController/AXWebViewController.h>
- (void)gotoAXWebViewControllerWithHtmlstr:(NSString*)html{
NSURL *baseURL = [NSURL fileURLWithPath:[[NSBundle mainBundle] bundlePath]];
AXWebViewController *webVC = [[AXWebViewController alloc] initWithHTMLString:html baseURL:baseURL];
UINavigationController *tmp = [[UINavigationController alloc]initWithRootViewController:webVC];
webVC.showsToolBar = NO;
webVC.navigationController.navigationBar.translucent = NO;
webVC.navigationController.navigationBar.tintColor = [UIColor colorWithRed:0.100f green:0.100f blue:0.100f alpha:0.800f];
webVC.navigationController.navigationBar.barTintColor = [UIColor colorWithRed:0.996f green:0.867f blue:0.522f alpha:1.00f];
//webVC.navigationType = AXWebViewControllerNavigationToolItem;
// webVC.showsToolBar = YES;
[self presentViewController:tmp animated:YES completion:^{
} ];
}
