I simply trying to add my passbook without sharing via email. How i can add my passbook on click button?
This code assumes that you know how to create the pass in the first place...
NSError * passerror;
PKPass * pass = [[PKPass alloc] initWithData:data error:&passerror];
if(!pass) {
UIAlertView* alertView = [[UIAlertView alloc] initWithTitle:#"Pass Failed" message:#"Sorry there was a problem creating your Passbook." delegate:nil cancelButtonTitle:#"OK" otherButtonTitles:nil];
[alertView show];
return;
}
//init a pass library
PKPassLibrary* passLib = [[PKPassLibrary alloc] init];
//check if pass library contains this pass already
if([passLib containsPass:pass]) {
//pass already exists in library, show an error message
UIAlertView* alertView = [[UIAlertView alloc] initWithTitle:#"Pass Exists" message:#"Pass is already in Passbook." delegate:nil cancelButtonTitle:#"OK" otherButtonTitles:nil];
[alertView show];
} else {
//present view controller to add the pass to the library
PKAddPassesViewController *vc = [[PKAddPassesViewController alloc] initWithPass:pass];
[vc setDelegate:(id)self];
[self presentViewController:vc animated:YES completion:nil];
}
EDIT You'll need to import
#import <PassKit/PassKit.h>

// Configure the fields of the interface.

It always goes in the else condition even when tested on real device. please help. this works in other Xcode versions
I am currently working on a project and using tesseract API .
The code is following :
UIImage *bwImage = [image g8_blackAndWhite];
[self.activityIndicator startAnimating];
// Display the preprocessed image to be recognized in the view
self.imageView.image = bwImage;
G8RecognitionOperation *operation = [[G8RecognitionOperation alloc] init];
operation.tesseract.engineMode = G8OCREngineModeTesseractOnly;
operation.tesseract.pageSegmentationMode = G8PageSegmentationModeAutoOnly;
operation.delegate = self;
operation.recognitionCompleteBlock = ^(G8Tesseract *tesseract) {
// Fetch the recognized text
NSString *recognizedText = tesseract.recognizedText;
NSLog(#"%#", recognizedText);
[self.activityIndicator stopAnimating];
// Spawn an alert with the recognized text
UIAlertView *alert = [[UIAlertView alloc] initWithTitle:#"OCR Result"
message:recognizedText
delegate:nil
cancelButtonTitle:#"OK"
otherButtonTitles:nil];
[alert show];
};
//NSLog(#"%#",);
// Finally, add the recognition operation to the queue
[self.operationQueue addOperation:operation];
}
I want to pass recognizedText string to second View controller but it is not visible outside the block.
How can I achieve this, any advice?
Declare recognizedText outside block with __block keyword to make it visible outside block.
Like below code:
......
__block NSString *recognizedText;//declared outside to make it visible outside block
operation.recognitionCompleteBlock = ^(G8Tesseract *tesseract) {
// Fetch the recognized text
recognizedText = tesseract.recognizedText;
NSLog(#"%#", recognizedText);
[self.activityIndicator stopAnimating];
// Spawn an alert with the recognized text
UIAlertView *alert = [[UIAlertView alloc] initWithTitle:#"OCR Result"
message:recognizedText
delegate:nil
cancelButtonTitle:#"OK"
otherButtonTitles:nil];
[alert show];
};
......
I have a tabbed application with 2 tab views. I want to change the view from the second tab to the first when the user presses "OK" on an alert view.
The following code snippet works when I use it on an -IBAction button pressed, but it doesn't do anything when I use it inside the alert code:
self.tabBarController.selectedViewController = [self.tabBarController.viewControllers objectAtIndex:0];
Why does it not work when used as below, in my SeondViewController.m in my
- (void)viewDidLoad {
[super viewDidLoad];?
UIAlertView *alert =[[UIAlertView alloc]
initWithTitle:#"Camera and Target coincident"
message:msg
delegate:nil
cancelButtonTitle:#"OK"
otherButtonTitles:nil];
[alert show];
self.tabBarController.selectedViewController = [self.tabBarController.viewControllers objectAtIndex:0];
I'm just learning this, so anything you can offer would be helpful.
When I use the following code:
if ([ theProjection Trans_Initialise] == 1) {
NSString * msg = nil;
UIAlertView *alertView =[[UIAlertView alloc] initWithTitle:#"Camera and Target coincident" message:msg delegate:self cancelButtonTitle:#"OK" otherButtonTitles:nil];
[alertView show];
- (void)alertView:(UIAlertView *)alertView clickedButtonAtIndex:(NSInteger)buttonIndex {
if ([[alertView buttonTitleAtIndex:buttonIndex] isEqualToString:#"OK"]) {
self.tabBarController.selectedIndex = 0;
}
}
I get the error message on -(void) alertView "Invalid argument type void to unary expression" Am I doing something grammatical, or is it (quite possibly) something I just didn't understand?
First of all, you need a delegate call back from the alert view informing you about the button that was clicked.
Your alert view should be created like this :
UIAlertView *alert =[[UIAlertView alloc] initWithTitle:#"Camera and Target coincident" message:msg delegate:self cancelButtonTitle:#"OK" otherButtonTitles:nil];
Then in your m file implement the function :
- (void)alertView:(UIAlertView *)alertView clickedButtonAtIndex:(NSInteger)buttonIndex {
if ([[alertView buttonTitleAtIndex:buttonIndex] isEqualToString:#"OK"]) {
self.tabBarController.selectedIndex = 0;
}
}
I'm creating an application that has integration with Twitter .. and wanted to know what have to do to create a button to add an image of the device in the tweet.and also wanted to know which framework to use it and also where the code
You can just use the twitter framework, it's included since iOS 5
And the code i use:
- (IBAction)twitter:(id)sender {
if([TWTweetComposeViewController canSendTweet])
{
NSLog(#"Ready to Tweet.");
TWTweetComposeViewController *tweetComposer = [[TWTweetComposeViewController alloc] init];
[tweetComposer setInitialText:[NSString stringWithFormat:#"My message"]];
[tweetComposer addImage:[UIImage imageNamed:#"114x114"]];
[tweetComposer addURL:[NSURL URLWithString:#"http://myPage"]];
tweetComposer.completionHandler = ^(TWTweetComposeViewControllerResult result){
if(result == TWTweetComposeViewControllerResultDone){
NSLog(#"Tweeted.");
} else if(result == TWTweetComposeViewControllerResultCancelled) {
NSLog(#"Cancelled.");
}
[self.navigationController dismissViewControllerAnimated:YES completion:nil];
};
[self presentModalViewController:tweetComposer animated:YES];
}else {
UIAlertView *alert = [[UIAlertView alloc] initWithTitle:#"Oops"
message:#"You can't send a tweet right now, make sure your device has an internet connection and you have at least one Twitter account setup"
delegate:nil
cancelButtonTitle:#"OK"
otherButtonTitles:nil];
[alert show];
[alert release];
}
}
i am a newbie to iOS and am trying to add inapt email in my app. I have a screen in which pushing the email icon should open the inapp email. I have the code for the inapp email. However, the button is already an outlet on the controller. So, I don't know how to link the same button to a different class/file which has the code for the inapp email. I was thinking of setting up a delegate but don't know how to initialize the delegate in the mail class. Have been struggling for a few days...please help!

Try MFMailComposeViewController.... here is some sample code:
Make sure you import the MEssageUI framework and import the MFMailComposeViewController/MessageUI in .h and also conform to its delegate
MFMailComposeViewController *mailView = [[MFMailComposeViewController alloc] init];
[mailView setMailComposeDelegate:self];
if ([MFMailComposeViewController canSendMail]) {
[mailView setSubject:#"Interesting Apple News Article!"];
NSString *mailString = [[NSString alloc] initWithFormat:#"Test!"];
[mailView setMessageBody:mailString isHTML:NO];
[mailView setModalTransitionStyle:UIModalTransitionStyleCoverVertical];
[self presentModalViewController:mailView animated:YES];
[mailString release];
[mailView release];
} else
[mailView release];
}
-(void)mailComposeController:(MFMailComposeViewController *)controller didFinishWithResult:(MFMailComposeResult)result error:(NSError *)error {
if (error) {
UIAlertView *alert = [[UIAlertView alloc] initWithTitle:#"Mailing Error" message:[error localizedDescription] delegate:self cancelButtonTitle:#"Dismiss" otherButtonTitles:nil, nil];
[alert show];
[alert release];
[self dismissModalViewControllerAnimated:YES];
} else {
[self dismissModalViewControllerAnimated:YES];
}
}
