iphone - 在 iphone SDK 中删除特定的 HTML 标签

Question

我有一个 NSString其中包含 HTML内容。但我想删除 < img src=..../>标记形式 NSString。

例如

Source = < p>< a href="http://wpcore.mpf.s3.amazonaws.com/wp-content/uploads/2012/12/thumbs_img_0500.jpg">**< img class="alignleft size-full wp-image-4730" style="margin-left: 5px; margin-right: 5px;" title="thumbs_img_0500" src="http://wpcore.mpf.s3.amazonaws.com/wp-content/uploads/2012/12/thumbs_img_0500.jpg" alt="thumbs img 0500" width="120" height="120" />**< /a>The two professional level < a title="3d printing" href="http://www.makepartsfast.com/category/products/3d-printers/">3D printers< /a> that build parts in color are the Zprinter from 3D Systems and the < a href="http://www.makepartsfast.com/2012/05/3812/mcor-announces-full-3d-color-3d-printer">Iris< /a> from Mcor Technologies. Earlier this year, Mcor Technologies announced its Iris full color 3D printer at the Rapid show and recently at Euromold. The Zprinter uses ink jetted into the build powder. The Iris, however, uses a different technique for creating color parts. Dr. Conor MacCormack, CEO of Mcor, discusses this technology.</p>

我的 img src 标签将一直不同。我该怎么做？？

我的代码:

-(void)viewWillAppear:(BOOL)animated
{
source = [NSString stringWithFormat:@"%@",[[self.parseResults objectAtIndex:k] objectForKey:@"summary"]];

NSLog(@"%@",source);
}

我通过将 HTML 转换为字符串来解决这个问题。

只需导入两个文件 NSString+HTML.h & NSString+HTML.m 文件。

然后调用 text_str=[html_str stringByConvertingHTMLToPlainText];
