convert string

[ziophase]

Hi All,

I need to be able to send data from the iPhone to a php script.

This has been working remarkably until I tried sending a string with an "&" symbol.

Naturally, this works fine:

mysite.com/test.php?var1=hello world&var2=hello world

but of course this doesn't:

mysite.com/test.php?var1=hello world & universe&var2=hello world

I have been using

NSString *addString = [NSString stringWithFormat:@"http://mysite.com/test.php?var1=%@&var2=%@",myVar1,myVar2];

Any ideas?

Cheers,

Tim

You need to encode myVar1 with the percent escape codes first-

myVar1 = [myVar1 stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding];

Thanks Smasher.

In the debugger and console, it appears that with you code, nothing has changed in the string.

myVar1 = [myVar1 stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding];

Any other ideas?

Sorry, I forgot that method doesn't handle ampersands. It should handle spaces and other problem characters though. Try this.

myVar1 = [myVar1 stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding];
myVar1 = [myVar1 stringByReplacingOccurrencesOfString:@"&" withString:@"%26"];

I've seen other solutions using CFURLCreateStringByAddingPercentEscapes if you want to google that.
