How to convert NSString to UTF8Encode ?
My NSLog print the same result as input string
NSString* username =#"MYUSERNAME";
username=[username stringByReplacingPercentEscapesUsingEncoding:NSUTF8StringEncoding];
NSString* Password =#"MYUSERNAMEPASS";
Password=[Password stringByReplacingPercentEscapesUsingEncoding:NSUTF8StringEncoding];
NSLog(#"username=%#",username);
NSLog(#"Password=%#",Password);
You need to use stringByAddingPercentEscapesUsingEncoding instead of stringByReplacingPercentEscapesUsingEncoding.
NSString *encodeUserName = [username stringByAddingPercentEscapesUsingEncoding:NSUTF32StringEncoding];
Also stringByAddingPercentEscapesUsingEncoding is deprecated so batter to use stringByAddingPercentEncodingWithAllowedCharacters like this
NSString *encodeUserName = [username stringByAddingPercentEncodingWithAllowedCharacters: [NSCharacterSet URLQueryAllowedCharacterSet]];

I have a NSString:
NSString *string1 = #"http://example.com/this-is-an-example-post"
By removing a range of characteres I have substringed it to:
NSString *string2 = #"this-is-an-example-post"
But I am struggling to get it into the form of:
NSString *string3 = #"this is an example post"
Any help? Much appreciated.
For example this way
string3 = [string2 stringByReplacingOccurrencesOfString:#"-" withString:#" "];

How to convert elements of NSMutableArray to NSString
(3 answers)
Closed 9 years ago.
I am trying to convert (or copy?) a NSMutableArray into a NSString. I guess my problem is that I don't really understand the structure of a NSString. In my limited knowledge, a string could look like this: in iphone
Try this code:-
NSString *string = [array componentsJoinedByString:#","];
take the NSMutableString and append every array string into your string
like
string = [string appendString:[NSString stringWithFormat:"%#", [array objectAtIndex:i]]];
