替换NSMutableAttributedString中的字符

Question

This works for a regular NSString :

NSString *newString = [myString stringByReplacingOccurrencesOfString:@"," withString:@""];

But there is no such method for NSMutableAttributedString . How could I remove all instances of a comma in an NSMutableAttributedString ?

Answer 1

let attrString = NSMutableAttributedString(string: "Hello <b>friend<b>")

attrString.mutableString.replaceOccurrencesOfString("<b>", withString: "", options: NSStringCompareOptions.CaseInsensitiveSearch, range: NSRange(location: 0, length: attrString.length))

Try this :)

Answer 2

Do it before you create the attributed string, if you can or depending on how you source it. If you can't then you can use replaceCharactersInRange:withString: (or replaceCharactersInRange:withAttributedString: ), but you need to know the range so you need to search and iterate yourself.

Answer 3

NSString *newString= "I want to ,show, you how to achieve this";
NSMutableAttributedString *displayText = [[NSMutableAttributedString alloc] initWithString:[NSString stringWithFormat:@"%@",newString]];
[[displayText mutableString] replaceOccurrencesOfString:@"," withString:@"" options:NSCaseInsensitiveSearch range:NSMakeRange(0, displayText.string.length)];

Answer 4

You can initialize the attributed string with the stripped string with the designed init. No?

Answer 5

The code could be applied from my answer here :

NSAttributedString *attributedString = ...;
NSAttributedString *anotherAttributedString = ...; //the string or characters which will replace

while ([attributedString.mutableString containsString:@"replace"]) {
        NSRange range = [attributedString.mutableString rangeOfString:@"replace"];
        [attributedString replaceCharactersInRange:range  withAttributedString:anotherAttributedString];
    }
