Question

我的NSString包含HTML内容。但我想删除< img src=..../>标记格式NSString。

e.g。

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标签会一直不同。我怎么能这样做？

我的代码：

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

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

Answer 1

我通过将HTML转换为字符串来解决它。

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

然后调用 text_str=[html_str stringByConvertingHTMLToPlainText] ;

Answer 2

//如下所示......让我知道它的工作与否!!!!

-(void)viewWillAppear:(BOOL)animated
{
 source = [NSString stringWithFormat:@"%@",[[self.parseResults objectAtIndex:k] objectForKey:@"summary"]];
 Source=[self flattenHTML:Source];//call flattenhtml method...
 NSLog(@"%@",source);
}


#pragma mark ---Removing HTML Tags
- (NSString *)flattenHTML:(NSString *)html {

NSScanner *theScanner;
NSString *text = nil;
theScanner = [NSScanner scannerWithString:html];

while ([theScanner isAtEnd] == NO) {

    [theScanner scanUpToString:@"<" intoString:NULL] ; 

    [theScanner scanUpToString:@">" intoString:&text] ;

}
html = [html stringByTrimmingCharactersInSet:[NSCharacterSet whitespaceAndNewlineCharacterSet]];

return html;
}
