如何从iPhone中的NSString中删除HTML标签？ [英] how to remove HTML Tags from NSString in iphone?

问题描述

我正在为我的应用程序需求工作日历功能。我今天点击日期或明天日期或其他日期需要在 UITextview 中显示吉利详情。我一直在尝试在我的文本视图中格式化字符串，但我无法解决它。我是xcode的新手。我想删除 HTML 我的stringResonse中的标签，并显示在 UITextview 。

I am working Calendar functionality for my app requirement.IF i click today date or tomorrow date or some other date need to display auspicious details in UITextview.I have been trying to format a string in my text view but I cant work it out. Im very new to xcode.I want to remove HTML Tags in my stringResonse and display in UITextview.

我在我的代码中这样写：

I am writing like this in my code:

-(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。

This is my string Response.

 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>

但如果用户点击日历中的日期，我想显示如下

S.Panchami 01.38

S.Panchami 01.38

Arudra 02.01
