Remove Ten Spaces After Specific Character - ios

Question

I have an string which is coming from a server :
<p>[phone] </p>
I want to remove any space after "tel:" up to 10 characters.
I tried this below code but didn't achieve my goal.
NSString *serviceMessage = dict[#"message"];
serviceMessage = [serviceMessage stringByReplacingOccurrencesOfString:#"<br />" withString:#"\n"];
serviceMessage = [serviceMessage stringByReplacingOccurrencesOfString:#"<div>" withString:#"\n"];
serviceMessage = [serviceMessage stringByReplacingOccurrencesOfString:#"<p>" withString:#""];
serviceMessage = [serviceMessage stringByReplacingOccurrencesOfString:#"</div>" withString:#""];
serviceMessage = [serviceMessage stringByReplacingOccurrencesOfString:#"</p>" withString:#""];
serviceMessage = [serviceMessage stringByReplacingOccurrencesOfString:#" " withString:#""];
serviceMessage = [serviceMessage stringByReplacingOccurrencesOfString:#"\n" withString:#" "];
NSString *mainString = serviceMessage;
if ([mainString containsString:#"tel:"]) {
NSUInteger location = [mainString rangeOfString:#"tel:"].location + 4;
NSString *newString = [mainString substringFromIndex:location];
[newString substringWithRange:NSMakeRange(10,0)];
NSString *newStr =[newString substringToIndex:12];
NSLog(#"New Trimed string:%#",newStr);
newStr = [newStr stringByReplacingOccurrencesOfString:#" " withString:#""];
NSLog(#"Final Trimed string:%#",newStr);
}
serviceMessage = [serviceMessage stringByTrimmingCharactersInSet:
[NSCharacterSet whitespaceAndNewlineCharacterSet]];
NSString *from = #"From : ";
NSString *dealerName = dict[#"messageFrom"];
NSString * append = [NSString stringWithFormat:#"%#%#%#%#",from, dealerName,#"\n",serviceMessage];

Answer 1

Try this
NSString *str1=#"Your Example No = 1";
NSArray *tempArray = [str1 componentsSeparatedByString:#"="];
str1 = [tempArray objectAtIndex:0];
NSLog(#"%#", str1);
Output is Your Example No
Hope this helps

If you want the telephone number after the "tel:", you can do it in following way
My code Snippet :
NSString *str = #"<p>[phone] </p> ";
NSLog(#"str = %#", str);
//It removes the unwanted extra character like (, ), -
NSCharacterSet *dontInclude = [NSCharacterSet characterSetWithCharactersInString:#"()-"];
NSString *strRemoveSpecial = [[str componentsSeparatedByCharactersInSet: dontInclude] componentsJoinedByString: #""];
//Now strRemoveSpecial is without those special character and we remove the space from the resulted string here
NSString *str1 = [strRemoveSpecial stringByTrimmingCharactersInSet:[NSCharacterSet whitespaceCharacterSet]];
NSLog(#"str1 = %#", str1);
//Here we separate string by "tel:" and takes the last part, which contains the telephone number
NSString *strAfterTel = [[strRemoveSpecial componentsSeparatedByString:#"tel:"] lastObject];
//Now substring to 10, which gives us the required telephone number.
NSString *firstTemAfterTel = [strAfterTel substringToIndex:10];
NSLog(#"firstTemAfterTel : %#", firstTemAfterTel);
Hope it helps.
Happy coding ...
