Get String From HTML String

- (NSString *)flattenHTML:(NSString *)htmlstr
{
NSScanner *theScanner;
NSString *text = nil;
theScanner = [NSScanner scannerWithString: htmlstr];
while ([theScanner isAtEnd] == NO) {
// find start of tag
[theScanner scanUpToString:@"<" intoString:NULL] ;
// find end of tag
[theScanner scanUpToString:@">" intoString:&text] ;
// replace the found tag with a space
//(you can filter multi-spaces out later if you wish)
htmlstr = [htmlstr stringByReplacingOccurrencesOfString:
[ NSString stringWithFormat:@"%@>", text]
withString:@" "];
} // while //
htmlstr=[htmlstr stringByReplacingOccurrencesOfString:@" " withString:@" "];
htmlstr=[htmlstr stringByReplacingOccurrencesOfString:@"\n" withString:@""];
htmlstr=[htmlstr stringByReplacingOccurrencesOfString:@"\r" withString:@""];
NSCharacterSet *set = [NSCharacterSet characterSetWithCharactersInString:@" "];
htmlstr =[htmlstr stringByTrimmingCharactersInSet:set]retain];
return htmlstr;
}

strPhone = [[strPhone componentsSeparatedByCharactersInSet:charactersToRemove] componentsJoinedByString:@""];

NSLog(@"%@",strPhone);

Result : Get 545646556665113 by removing -,( and ) from string

NSString *strPhone = @"54564-6556-6-65(113)";

Iphone:Trimming whitespace characters from NSString

If you need to trim whitespace characters at the start and end of a NSString, here’s an easy way:

existingStr = [ existingStr stringByTrimmingCharactersInSet:[NSCharacterSet whitespaceAndNewlineCharacterSet]] ;

UTF String Convertion

-(NSString *)encodeString:(NSString *)string
{
NSString *result = (NSString *)CFURLCreateStringByAddingPercentEscapes(kCFAllocatorDefault, (CFStringRef)string, NULL, CFSTR("% '\"?=&+<>;:-"), kCFStringEncodingUTF8); return [result autorelease];

}

or

We Can insert %20 in place on Space in String by below statement:
str =[str stringByAddingPercentEscapesUsingEncoding:NSStringEncodingConversionExternalRepresentation];
