remove all accents by string

Question

surnameField.text = "Fal à èà ò l'opo";    

// remove space and apostrophe
NSString *surnarmeInput = [[surnameField.text stringByReplacingOccurrencesOfString:@" " withString:@""] stringByReplacingOccurrencesOfString:@"'" withString:@""];

I would remove also accents.

Result "Falaeaolopo"

// convert to a data object, using a lossy conversion to ASCII
NSData *asciiEncoded = [yourOriginalString dataUsingEncoding:NSASCIIStringEncoding
                         allowLossyConversion:YES];

// take the data object and recreate a string using the lossy conversion
NSString *other = [[NSString alloc] initWithData:asciiEncoded
                                        encoding:NSASCIIStringEncoding];
// relinquish ownership
[other autorelease];

which will remove all the accents..To remove all spaces

NSString *yourFinalString = [other stringByReplacingOccurrencesOfString:@" " withString:@""];

First part of removing accent, code copied from dreamlax's answer in this thread..

Careful, this remove not only accents, remove other characters like the Spanish letter `ñ` for example. — jherran, Jan 21 '15 at 12:33

Using dataUsingEncoding:allowLossyConversion: doesn't seem to work for some characters - Đ and đ for example. I use a specific check for these, followed by the ascii encoding.

Try the dataUsingEncoding:allowLossyConversion: method in NSString.

i think is not applicable method in NSString – Maurizio Nov 01 '11 at 10:56
Just convert the NSData to a String with a `initWithData:encoding:` (NSString). – Marcelo Alves Nov 01 '11 at 10:58
