コンテンツをNSString含む がありHTMLます。< img src=..../>しかし、タグフォーム NSStringを削除したいです。

例えば

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>

私の img src タグは常に異なります。これどうやってするの？？

私のコード:

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

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

HTMLを文字列に変換することで解決しました。

2 つのファイルNSString+HTML.h と NSString+HTML.mファイルをインポートするだけです。

次に呼び出されtext_str=[html_str stringByConvertingHTMLToPlainText]ます。

//以下のようにしてください...動作しているかどうかを教えてください!!!!

-(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;
}
