}
This code worked fine in iOS7. After I upgraded my device to iOS8, the program was blocked and imagePickerView didn't dismiss.
Is this a bug in iOS8? Anyone can help me?

{
NSURL *assetURL = [info objectForKey:UIImagePickerControllerReferenceURL];
__block NSString *fileName = nil;

hi in my app i am able to take a photo or select a photo from library and display it in a imageview
but my question is how can i add a second image view and display a image in that
here is my code
- (IBAction)TakePhoto:(id)sender {
picker = [[UIImagePickerController alloc] init];
picker.delegate = self;
[picker setSourceType:UIImagePickerControllerSourceTypeCamera];
[self presentViewController:picker animated:YES completion:NULL];
}
- (IBAction)ChoosePhoto:(id)sender {
picker = [[UIImagePickerController alloc] init];
picker.delegate = self;
[picker setSourceType:UIImagePickerControllerSourceTypePhotoLibrary];
[self presentViewController:picker animated:YES completion:NULL];
}
- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info
{
image = [info objectForKey:UIImagePickerControllerOriginalImage];
[ImageView setImage:image]; // "myImageView" name of any UImageView.
[self dismissViewControllerAnimated:YES completion:NULL];
}
-(void)imagePickerControllerDidCancel:(UIImagePickerController *)picker {
[self dismissViewControllerAnimated:YES completion:NULL];
}
What I think from your question is you are going to select two image one bye one.
Either from camera or from photo library.
Try this one:
- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info
{
image = [info objectForKey:UIImagePickerControllerOriginalImage];
if(ImageView.image == Nil)
{
[ImageView setImage:image];
}
else if(ImageView2.image == Nil)
{
[ImageView2 setImage:image];
}
[self dismissViewControllerAnimated:YES completion:NULL];
}
After picking image from UIImagePickerController I want to Tweet it but there is error!
Warning: Attempt to present <SLTwitterComposeViewController: 0x210d84b0> on <UITabBarController: 0x1fd67650> while a presentation is in progress!
P.S
This is tabbar application (4 tabbars)
All code:
-(void)useCamera:(id)sender
{
if ([UIImagePickerController isSourceTypeAvailable:UIImagePickerControllerSourceTypeCamera]){
UIImagePickerController *imagePicker =[[UIImagePickerController alloc] init];
imagePicker.delegate = self;
imagePicker.sourceType = UIImagePickerControllerSourceTypeCamera;
imagePicker.mediaTypes = #[(NSString *) kUTTypeImage];
imagePicker.allowsEditing = NO;
[self presentViewController:imagePicker animated:YES completion:nil];
_newMedia = YES;
}
}
-(void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info{
NSString *mediaType = info[UIImagePickerControllerMediaType];
[self dismissViewControllerAnimated:YES completion:nil];
if ([mediaType isEqualToString:(NSString *)kUTTypeImage]) {
[self buttonTweet:info[UIImagePickerControllerOriginalImage]];
}
}
- (IBAction)buttonTweet:(id)sender {
SLComposeViewController *composeController = [SLComposeViewController composeViewControllerForServiceType:SLServiceTypeTwitter];
[composeController setInitialText:[NSString stringWithFormat:#"#this is tweet text"]];
[composeController addImage:sender];
[composeController addURL: [NSURL URLWithString:#"http://www.abc.com"]];
[self presentViewController:composeController animated:YES completion:nil];
}
You are presenting a new view controller while the old one is still disappearing. You can present the new one upon completion of the other animation by doing it like this:
[self dismissViewControllerAnimated:YES completion:^{
if ([mediaType isEqualToString:(NSString *)kUTTypeImage]) {
[self buttonTweet:info[UIImagePickerControllerOriginalImage]];
}
}];
I have a problem with the UIActivityViewController on iPad
Here is my Code:
NSString* someText = #"Hi, I am using the official iEveryThing Tech app #iEveryTech";
NSString* Website = [NSURL URLWithString:#"https://itunes.apple.com/us/app/ieverytech/id578148847?l=de&ls=1&mt=8"];
NSArray* dataToShare = #[someText,Website];
Class activityViewController = NSClassFromString(#"UIActivityViewController");
if(activityViewController) {
UIActivityViewController* activityViewController =
[[UIActivityViewController alloc] initWithActivityItems:dataToShare
applicationActivities:nil];
[self presentViewController:activityViewController animated:YES completion:nil];}
}
On iPhone the Mail composer View will disappear after sending the mail but not the Composer on the iPad here is my Composer:
-(void)mailComposeController:(MFMailComposeViewController *)controller didFinishWithResult:(MFMailComposeResult)result error:(NSError *)error {
if (error) {
UIAlertView *alert = [[UIAlertView alloc] initWithTitle:#"error"
message:[NSString stringWithFormat:#"error %#", [error description]]
delegate:nil cancelButtonTitle:#"Dismiss" otherButtonTitles:nil, nil];
[alert show];
[self dismissModalViewControllerAnimated:YES];
}
else {
[self dismissModalViewControllerAnimated:YES];
}
}
The activityViewController use a native method for send mail don't need use mailComposeController, like this
NSMutableArray *items = [NSMutableArray new];
[items addObject:#"text for share"];
[items addObject:[UIImage imageWithData:[NSData dataWithContentsOfFile:self.imagePath]]];
NSArray *activityItems = [NSArray arrayWithArray:items];
self.activityVC = [[UIActivityViewController alloc] initWithActivityItems:activityItems applicationActivities:[NSArray arrayWithObjects:whatsapp,instagram, nil]];
self.activityVC.excludedActivityTypes = #[UIActivityTypeAssignToContact, UIActivityTypePrint,UIActivityTypeAirDrop,UIActivityTypeCopyToPasteboard];
[self presentViewController:self.activityVC animated:YES completion:nil];
First thing, when using the activityViewController, your class is not the delegate for the mail composer and the code will not be called. This is all handled internally in the activityViewController.
As for your view not being dismissed, implement the complete block call for the activityViewController. In the block be sure to dismiss the view controller.
I was using UIImagePickerController without any problem.
Before when I was taking a picture in the landscape mode, the picture in the Preview (when the buttons Retake and Use Photo were present) was always automatically rotated so as to appear correctly in the portrait mode.
But now when I use the UIImagePickerController the preview mode does not rotate the picture anymore.
Where can I activate or desactivate this mode?
Here is my code:
- (IBAction)getCameraPicture{
//Create an UIImagePickerController to be able to take a picture
UIImagePickerController *picker = [[UIImagePickerController alloc] init];
picker.delegate = self;
picker.sourceType = UIImagePickerControllerSourceTypeCamera;
picker.allowsImageEditing = NO;
[self presentModalViewController:picker animated:YES];
[picker release];
- (IBAction)selectExistingPicture{
if ([UIImagePickerController isSourceTypeAvailable:UIImagePickerControllerSourceTypePhotoLibrary]) {
UIImagePickerController *picker = [[UIImagePickerController alloc] init];
picker.delegate = self;
picker.sourceType = UIImagePickerControllerSourceTypePhotoLibrary;//Here is specified the fact that the picker source is the library
[self presentModalViewController:picker animated:YES];
[picker release];
}
else {
UIAlertView *alert = [[UIAlertView alloc] initWithTitle:#"Error accessing photo library" message:#"Device does not support a photo library" delegate:nil cancelButtonTitle:#"Drat!" otherButtonTitles:nil];
[alert show];
[alert release];
}
}
- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingImage:(UIImage *)image editingInfo:(NSDictionary *)editingInfo {
int imageCase=0;
UIImage *imageSaved=rotateImage(image);
UIImage* imageNormal =scaleImage(imageSaved,imageCase);
imageView.image = imageNormal;
[picker dismissModalViewControllerAnimated:YES];
}
- (void)imagePickerControllerDidCancel:(UIImagePickerController *)picker {
[picker dismissModalViewControllerAnimated:YES];
}
I really need to at least understand what is happening so any help would be really appreciated even if it is not the solution!
Thanks folks!
one possibility is that you need to call
[[UIDevice currentDevice] beginGeneratingDeviceOrientationNotifications];
