Re: [twitter-dev] problem in Posting a tweet using OAuth from IOS app
I assume that your URL encoding is wrong in the OAuth code. Make sure
that you use %20 for a space and not +. The standard NSString URLencode
function won't really work.
Code that has always worked for me to URLencode (got it from the web
somewhere, sorry for not mentioning the original author) :
+(NSString*)urlEncode:(NSString*)str {
return [(NSString *)CFURLCreateStringByAddingPercentEscapes(
NULL,
(CFStringRef)str,
NULL,
(CFStringRef)@"!*'();:@&=+$,/?%#[]",
kCFStringEncodingUTF8 ) autorelease];
}

For example the tweet : "ThisIsATweet" works, but the tweet : "this is
a tweet" doesn't work here's my http request body code:
NSData* body =[NSString stringWithFormat:@"status=%@",[self

[request setValue:@"application/x-www-form-urlencoded"

[twitter-dev] problem in Posting a tweet using OAuth from IOS app
I am building a twitter client for the IPhone and I'm using OAuth to
authenticate my requests to twitter,
Right now I am able to get the home time line and even post tweets
( that do not contain any spaces or symbols) the problem starts when I
try to post a tweet that contains spaces for example it gives me :
{"error":"Incorrect signature","request":"\/1\/statuses\/update.json"}
For example the tweet : "ThisIsATweet" works, but the tweet : "this is
a tweet" doesn't work here's my http request body code:
NSData* body =[NSString stringWithFormat:@"status=%@",[self
percentageEncoding:tweet]];
[request setValue:@"application/x-www-form-urlencoded"
forHTTPHeaderField:@"Content-Type"];
[request setValue:[NSString stringWithFormat:@"%d",[body length]]
forHTTPHeaderField:@"Content-Length"];
[request setHTTPBody:[body
dataUsingEncoding:NSISOLatin1StringEncoding]];
