I am receiving this error when trying to post an image to Twitter using the following code, cannot think what I am doing wrong any ideas for how to solve?;
- (void)PostToTwitter
{
UIImage* pxImage = [[self GetResultImage] retain];
TWTweetComposeViewController *twitter = [[[TWTweetComposeViewController alloc] init] autorelease];
[twitter setInitialText:#"Twitter Pic"];
[twitter addImage:pxImage];
FaceAppDelegate* app = (FaceAppDelegate*)[[UIApplication sharedApplication] delegate];
[app.mainCtrl presentViewController:twitter animated:YES completion:NULL];
twitter.completionHandler = ^(TWTweetComposeViewControllerResult res)
{
if(res == TWTweetComposeViewControllerResultDone)
{
UIAlertView *alert = [[UIAlertView alloc]initWithTitle:#"Success" message:#"You have posted successfully." delegate:self cancelButtonTitle:#"Close" otherButtonTitles: nil];
[alert show];
[alert release];
}
else if(res == TWTweetComposeViewControllerResultCancelled)
{
UIAlertView *alert = [[UIAlertView alloc]initWithTitle:#"Cancelled" message:#"You have cancelled posting to Twitter." delegate:NULL cancelButtonTitle:#"Close" otherButtonTitles: nil];
[alert show];
[alert release];
}
[app.mainCtrl dismissModalViewControllerAnimated:YES];
};
[pxImage release];
}
I think, that your view isn't presented. Try to use app.window.rootViewController, not property mainContr.
thanks in advance every time I call to create an in app SMS i get the following error...
Application tried to push a nil view controller on target .
This is the code I have that worked in OS 4 SDK...
MFMailComposeViewController *MailController;
MFMessageComposeViewController *SMScontroller;
NSError *error;
NSString *EmailMessage;
NSString *SubjectMessage;
-(IBAction)sendInAppSMS
{
if([MFMessageComposeViewController canSendText])
{
SMScontroller = [[MFMessageComposeViewController alloc] init];
SMScontroller.messageComposeDelegate = self;
NSString *MessageString = #"Hello";
SMScontroller.body = MessageString;
SMScontroller.navigationBar.tintColor = [UIColor blackColor];
[[UIApplication sharedApplication] setStatusBarStyle:UIStatusBarStyleBlackOpaque];
[self presentModalViewController:SMScontroller animated:YES];
[[UIApplication sharedApplication] setStatusBarStyle:UIStatusBarStyleBlackOpaque];
}
else{
// alertView to tell user to setup a mail account.
NSString *message = [[NSString alloc] initWithFormat:#"To use this feature, you need to have an iPhone with SMS abilities."];
UIAlertView *alert = [[UIAlertView alloc] initWithTitle:#"SMS Account Not Detected" message:message delegate:nil cancelButtonTitle:#"Understood" otherButtonTitles:nil];
[alert show];
}
}
- (void)messageComposeViewController:(MFMessageComposeViewController *)controller didFinishWithResult:(MessageComposeResult)result
{
switch (result) {
case MessageComposeResultCancelled:
{
UIAlertView *alert = [[UIAlertView alloc] initWithTitle:#"I Like It" message:#"User cancelled sending the SMS"
delegate:self cancelButtonTitle:#"OK" otherButtonTitles: nil];
[alert show];
}
break;
case MessageComposeResultFailed:
{
UIAlertView *alert = [[UIAlertView alloc] initWithTitle:#"I Like It" message:#"Error occured while sending the SMS"
delegate:self cancelButtonTitle:#"OK" otherButtonTitles: nil];
[alert show];
}
break;
case MessageComposeResultSent:
{
UIAlertView *alert = [[UIAlertView alloc] initWithTitle:#"I Like It" message:#"SMS sent successfully..!"
delegate:self cancelButtonTitle:#"OK" otherButtonTitles: nil];
[alert show];
}
break;
default:
break;
}
[self dismissModalViewControllerAnimated:YES];
}
I believe if you are running this in the simulator you'll get the error since it doesn't have sms. I get the same error in simulator but if i connect to my phone it works fine.
I'm trying to trigger an AlertView when my camera detect a face using OpenCV. I manage to do the face detection and can output an NSLog successfully. But when I tried to trigger the alert view with
NSLog(#"Face Detected");
UIAlertView *alert = [[[UIAlertView alloc] initWithTitle:#"Face Detected" message:#"Do you really want to try again?" delegate:self cancelButtonTitle:#"Cancel" otherButtonTitles:nil] autorelease];
[alert addButtonWithTitle:#"Yes"];
[alert show];
[alert release];
I can see the Alert View is kind of triggered as the screen is dimmed but I could never see the alert view came out...
Thanks for helping!
Remove [alert release]. You already called autorelease on it.
Also, you can integrate [alert addButtonWithTitle:#"Yes"]; in the initializer:
UIAlertView *alert = [[[UIAlertView alloc] initWithTitle:#"Face Detected"
message:#"Do you really want to try again?"
delegate:self
cancelButtonTitle:#"Cancel"
otherButtonTitles:#"OK", nil] autorelease];
where are you calling this from ? Main thread or secondary ?
Because UIKit stuff should always been done on main thread.
Code example:
- (void)opencvFaceDetect
{
// stuff before
[self performSelectorOnMainThread: #selector(openAlertView) withObject:nil waitUntilDone:false];
// stuff after
}
and then
- (void)openAlertView
{
UIAlertView *alert = [[[UIAlertView alloc] initWithTitle:#"Face Detected"
message:#"Do you really want to try again?"
delegate:self
cancelButtonTitle:#"Cancel"
otherButtonTitles:#"OK", nil] autorelease];
}
i want simply to show a double value on a uialert view it is possible?
Put the value into a formatted NSString and send that to the alertView:
NSString *messageString = [NSString stringWithFormat:"#number = %.2f", 42.0];
UIAlertView* alertView = [[UIAlertView alloc] initWithTitle:#"Title text" message:messageString delegate:self cancelButtonTitle:#"OK" otherButtonTitles:nil];
[alertView show];
[alertView release];
How are you showing the UIAlertView now? Something like the following should work:
double myDouble = 12.6;
NSString *alertString = [NSString stringWithFormat:#"%g", myDouble];
UIAlertView *myAlert = [[UIAlertView alloc] initWithTitle:alertString
message:nil
delegate:nil
cancelButtonTitle:nil
otherButtonTitles:nil];
[myAlert show];
I am creating an iphone application in which I have to upload photos using different services.
I am successful in uploading photos with Twitpic & YFrog but not able to do with Plixi.
I am using Oauth ,as Twitter is not allowing Basic authentication.
If anyone has tried with Plixi ,please help me out!!
I have googled a lot but not getting any relevant documentation for the new Oauth for Plixi.
Finally, I am with a solution for my problem :)
If anyone is also stuck with this problem, just add the TweetPhoto folder from the following application link:
http://code.google.com/p/tweetphoto-api-objective-c/downloads/detail?name=TPAPI-Objective-C-Library.zip
Change the tweetphoto urls for plixi now.
Also, can refer to my following code for making function calls:
-(void)uploadtoTweetPhoto{
NSString *message = [self.tweetTextView.text stringByReplacingOccurrencesOfString:#"Max. 140 characters" withString:#""];
NSMutableDictionary *dictionary = [[NSMutableDictionary alloc]init];
if((message == nil) || ([message isEqual:#""])){
UIAlertView *alert = [[UIAlertView alloc] initWithTitle: #"Please enter your tweet message.." message: #"" delegate:nil cancelButtonTitle: #"Ok" otherButtonTitles: nil];
[alert show];
[alert release];
}
else{
[dictionary setObject:message forKey:#"message"];
}
if([dictionary count] == 1){
[indicator startAnimating];
[NSThread detachNewThreadSelector:#selector(uploadPhotoToTweetPhoto:) toTarget:self withObject:dictionary];
}
[dictionary release];
}
- (void)uploadPhotoToTweetPhoto:(NSDictionary *)dictionary{
NSString *message = [dictionary objectForKey:#"message"];
NSAutoreleasePool *pool = [[NSAutoreleasePool alloc] init];
NSString *accessTokenKey = [[NSUserDefaults standardUserDefaults] valueForKey:#"oauth_token"];
NSString *accessTokenSecret = [[NSUserDefaults standardUserDefaults] valueForKey:#"oauth_token_secret"];
TweetPhoto *tweetPhoto = [[TweetPhoto alloc] initWithSetup:accessTokenKey identitySecret:accessTokenSecret apiKey:Plixi_API_Key serviceName:#"Twitter" isoAuth:YES];
NSData *dat =[tweetPhoto upload:UIImageJPEGRepresentation(self.imgView.image,0.8) comment:message tags:#"" latitude:23.4646 longitude:-87.7809 returnType:TweetPhotoCommentReturnTypeXML];
NSString *status =[NSString stringWithFormat:#"%i",[tweetPhoto statusCode]];
[tweetPhoto release];
[self performSelectorOnMainThread:#selector(photoUploadedtoTweetPhoto:) withObject:status waitUntilDone:[NSThread isMainThread]];
[pool release];
}
- (void)photoUploadedtoTweetPhoto:(NSString*)status{
[indicator stopAnimating];
if([status isEqualToString:#"201"])
{
UIAlertView *alert = [[UIAlertView alloc] initWithTitle: #"Tweet Posted" message: #"" delegate:nil cancelButtonTitle: #"Ok" otherButtonTitles: nil];
[alert show];
[alert release];
}
else {
UIAlertView *alert = [[UIAlertView alloc] initWithTitle: #"Tweet Failed" message: #"" delegate:nil cancelButtonTitle: #"Ok" otherButtonTitles: nil];
[alert show];
[alert release];
}
}
I'm curious as to the phrase you used in Google. In any case, googling "plixi api" tool me to this page, which links to a Cocoa wrapper on Google Code.
