NSString ==> remove "carriage return" ?????

[aryaxt]

How can i remove the carriage return from my NSString???
I tried :
str = [str stringByReplacingOccurrencesOfString:@"\n" withString:@""];
but that didn't remove it

[david_david]

It works fine..

NSString *test = @"123\n4";
test = [test stringByReplacingOccurrencesOfString:@"\n" withString:@""];
	
UIAlertView *alert = [[UIAlertView alloc] initWithTitle:NSLocalizedString(@"ApplicationName", @"") 
													message:test
												   delegate:self cancelButtonTitle:NSLocalizedString(@"Cancel", @"") otherButtonTitles:NSLocalizedString(@"OK", @""), nil];
	

[alert show];
[alert release];

there is no "\n" in my string, but when i use NSLog to see it's data i see that at some points the string skips to a new line

Thats what a "\n" IS.

If you're carriage return is only at the end of the line you can try

str = [str stringByTrimmingCharactersInSet:[NSCharacterSet newlineCharacterSet]];

thanks for the reply, and no the carriage return is all over the place. is there a way to remove them all.
Is replacing "\n" with "" suppose to work?

The thing about carriage returns, some OS's put in more than just "\n".

Try the following:

NSArray* newLineChars = [NSArray arrayWithObjects:@"\u000A", @"\u000B",@"\u000C",@"\u000D",@"\u0085",nil];

for( NSString* nl in newLineChars )
    str = [str stringByReplacingOccurrencesOfString: nl withString:@""];

[aryaxt]

I get an error on this, it won't build
'\u000A' is not a valid universal character
'\u000B' is not a valid universal character
'\u000D' is not a valid universal character
'\u0085' is not a valid universal character

[smithdale87]

Sorry, wasntpositive how to put those chars, and since I'm not near a mac, I can't verify. One moment, I'm sure some googling can figure this out..

[smithdale87]

This may be usefu, try this: ( Again not near my mac, so you get to be the guinea pig )

NSArray* newLineChars = [NSArray arrayWithObjects:@"\\u000A", @"\\u000B",@"\\u000C",@"\\u000D",@"\\u0085",nil];

I would like to also display on the web a text composed on the iPhone.
The problem is that when I display it on a web text area all newlines are turned into %10.
Conversely when I write the text on the web it get displayed correctly on the iPhone.
The question is what operation should I make to the NSString before submitting it to the sql server so to replace the %10's with more portable characters.

If you have problem/question don't just post it in any random thread. Create a new thread for it. If some other thread is relevant, link to it.
