NSString stringWithFormat example objc

Following code fragment shows how to use NSString:stringWithFormat method. stringWithFormat method performs the same work as C's printf() function. The object created by stringWithFormat is auto-released. Please note that you should prefix @ to all Objective-C strings.


NSString *urlString = [NSString stringWithFormat:@"%@/accounts/%d/apps/%d/dev-msgs", ILIME_BASE_URL, ILIME_ACCOUNT_ID, ILIME_APP_ID];
NSString *sendMessage = [NSString stringWithFormat:messageText.text];
NSString *requestBody = [NSString stringWithFormat:@"%@< notificationRequest>", sendMessage]; NSURL* url = [NSURL URLWithString:urlString]; [self postMessage:requestBody toURL:urlString];
