如何从 iPhone 中的 NSString 中删除 HTML 标签？

我正在使用日历功能来满足我的应用程序要求。如果我单击今天日期或明天日期或其他某个日期，则需要在其中显示吉祥详细信息UITextview.我一直在尝试在文本视图中格式化字符串，但无法解决。我对 xcode 很陌生。我想删除HTML我的字符串中的标签响应并显示在UITextview.

我在我的代码中这样写：

-(void)connectionDidFinishLoading:(NSURLConnection *)connection

{

[UIApplication sharedApplication].networkActivityIndicatorVisible=NO;

if(connection==urlConnection)

{

NSString *strResponse=[[NSString alloc]initWithData:responseData encoding:NSUTF8StringEncoding];

NSLog(@"String Response is : %@",strResponse);

NSMutableString *mutString=[NSMutableString string];

NSString *s=nil;

NSString *s1=nil;

//NSArray *arr1=[strResponse componentsSeparatedByCharactersInSet:[NSCharacterSet characterSetWithCharactersInString:@"<br>"]];

NSArray *arr2=[strResponse componentsSeparatedByString:@"\n"];

NSLog(@"array %@",arr2);

for(s in arr2)

{

s = [s stringByReplacingOccurrencesOfString: @"<br>" withString: @"\n"];

s1=[s stringByReplacingOccurrencesOfString:@"<font color>" withString:@" "];

[mutString appendString:@""];

[mutString appendString:s1];

}

text1.text=[text1.text stringByAppendingString:mutString];

}

}

- (void)viewDidLoad

{

[super viewDidLoad];
    // Do any additional setup after loading the view.

strZone=[[NSString alloc]init];

dict=[[NSDictionary alloc]init];

text1=[[UITextView alloc]initWithFrame:CGRectMake(10, 280, 300, 120)];

text1.font=[UIFont fontWithName:@"Helvetica" size:12];

text1.font=[UIFont boldSystemFontOfSize:12];

text1.backgroundColor=[UIColor whiteColor];

text1.editable=NO;

[self.view addSubview:text1];

}

这是我的字符串响应。

 S.Panchami 01.38<br>Arudra 02.01<br>V.08.54-10.39<br>D.05.02-06.52<br> <font color=red><u>Festival</u></font><br><font color=blue>Shankara Jayanthi<br></font>

但如果用户单击日历中的日期，我想像这样显示

潘查米 01.38

阿鲁陀罗 02.01

V.08.54-10.39

D.05.02-06.52

Festival

尚卡拉·贾扬蒂

iOS 7 的简单解决方案：

NSString *html = @"S.Panchami 01.38<br>Arudra 02.01<br>V.08.54-10.39<br>D.05.02-06.52<br> <font color=red><u>Festival</u></font><br><font color=blue>Shankara Jayanthi<br></font>";
NSAttributedString *attr = [[NSAttributedString alloc] initWithData:[html dataUsingEncoding:NSUTF8StringEncoding]
                                                            options:@{NSDocumentTypeDocumentAttribute: NSHTMLTextDocumentType,
                                                                      NSCharacterEncodingDocumentAttribute:@(NSUTF8StringEncoding)}
                                                 documentAttributes:nil
                                                              error:nil];
NSLog(@"html: %@", html);
NSLog(@"attr: %@", attr);
NSLog(@"string: %@", [attr string]);
NSString *finalString = [attr string];
