How to replace a character in Objective-C String for iPhone SDK?

NSString *str = @”tutori@als”;
Now we have a choice of replacing characters in this string and creating new one, or modify this same string. In this example we will modify this string and print in the next line.
str = [str stringByReplacingOccurrencesOfString:@”@” withString:@””]; NSLog(@”%@”,str);
When we run the above code, str is replaced with “tutorials” which was previously “tutori@als”.

Replacing text in a string using replacingOccurrences(of:)
Replacing text in a string using replacingOccurrences(of:)
Swift version: 5.6
Paul Hudson @twostraws June 1st 2019
It’s easy to replace text inside a string thanks to the method replacingOccurrences(of:) . This is a string method, and you tell it what to look for and what to replace it with, and you’re done.
For example:
let str = “Swift 4.0 is the best version of Swift to learn, so if you’re starting fresh you should definitely learn Swift 4.0.” let replaced = str.replacingOccurrences(of: “4.0”, with: “5.0”)
That will make replaced equal to “Swift 5.0 is the best version of Swift to learn, so if you’re starting fresh you should definitely learn Swift 5.0.”
