You can't select multiple photos or videos simultaneously
You have to use custom ImagePicker. And I think ELCImagePickerController is the best option in my opinion.
There is also some other library that can be used..
ELCImagePickerController
WSAssetPickerController
QBImagePickerController
ZCImagePickerController
CTAssetsPickerController
AGImagePickerController

After picking the image from gallery or camera - needs to enable rotate, flip editing How can i acive that.Here my code :
-(void)photofromCamera
{
#try
{
NSLog(#"2");
UIImagePickerController *picker = [[UIImagePickerController alloc] init];
picker.delegate = self;
picker.allowsEditing = YES;
picker.sourceType = UIImagePickerControllerSourceTypeCamera;

UIImagePickerController *picker = [[UIImagePickerController alloc] init];
picker.delegate = self;
picker.allowsEditing = YES;
picker.sourceType = UIImagePickerControllerSourceTypePhotoLibrary;
[self presentViewController:picker animated:YES completion:NULL];
}
So after the delegate method :
- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info {
[self.imageDeletionButton setHidden:NO];
UIImage *chosenImage = [info valueForKey:UIImagePickerControllerEditedImage];
self.PostImageView.image = chosenImage;
[picker dismissViewControllerAnimated:YES completion:nil];
}
As if now, if i pick any image from gallery, camera - i needs to show the crop, flip, rotation.please help me out how can i achive that.
Thanks in advance !!!
You can use the swift based framework IGRPhotoTweaks for rotate, flip and crop the image.
You can check the https://github.com/IGRSoft/IGRPhotoTweaks for git and
https://cocoapods.org/pods/IGRPhotoTweaks for cocoapods.
In the framework cropAction() and changedAngel(value: radians) are the 2 methods that you need to try to achieve your requirement.
I'm using ios 8.4. When debugging an app, and I present a UIImagePickerController, xcode loses connection with the iphone. This wasn't a problem before.
Sometimes it will bring up the image picker... but then when I save an image, there'll be a crash.
Is anyone else experiencing this? How to fix?
UIImagePickerController *imagePickerController = [[UIImagePickerController alloc] init];
imagePickerController.sourceType = UIImagePickerControllerSourceTypeCamera;
imagePickerController.editing = NO;
imagePickerController.delegate = self;
imagePickerController.showsCameraControls=YES;
[self presentViewController:imagePickerController animated:YES completion:nil];
try this code
- (IBAction)galleryButtonPressed:(id)sender
{
UIImagePickerController *pickerController = [[UIImagePickerController alloc] init];
if ([UIImagePickerController isSourceTypeAvailable:UIImagePickerControllerSourceTypePhotoLibrary]) {
pickerController.sourceType = UIImagePickerControllerSourceTypePhotoLibrary;
pickerController.allowsEditing = YES;
pickerController.delegate = self;
[self presentViewController:pickerController animated:YES completion:NULL];
}
}
#pragma mark - UIImagePickerControllerDelegate
- (void)imagePickerController:(UIImagePickerController *)picker
didFinishPickingMediaWithInfo:(NSDictionary *)info
{
[self dismissViewControllerAnimated:YES completion:NULL];
UIImage *image = [info objectForKey:UIImagePickerControllerEditedImage];
if (image == nil)
image = [info objectForKey:UIImagePickerControllerOriginalImage];
// Do something with the image
[self.imageView setImage:image];
}
- (void)imagePickerControllerDidCancel:(UIImagePickerController *)picker
{
[self dismissViewControllerAnimated:NO completion:nil];
}
In iOS 8, When i click to open the camera from my ipad mini it gives warning
"Snapshotting a view that has not been rendered results in an empty snapshot"
I am using the below code to open camera from my device.
- (IBAction)takePhotograph:(UIButton *)sender {
UIImagePickerController *picker = [[UIImagePickerController alloc] init];
picker.delegate = self;
picker.allowsEditing = YES;
picker.sourceType = UIImagePickerControllerSourceTypeCamera;
[self presentViewController:picker animated:YES completion:NULL];
}
- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info {
UIImage *chosenImage = info[UIImagePickerControllerEditedImage];
[self.cmdTakePhotograph setImage:chosenImage forState:UIControlStateNormal];
[picker dismissViewControllerAnimated:YES completion:NULL];
imageTaken = 1;
Compress = 1;
self.lblErrMsg.hidden = YES;
}
- (void)imagePickerControllerDidCancel:(UIImagePickerController *)picker {
[picker dismissViewControllerAnimated:YES completion:NULL];
}
Please suggest me solution to remove this warning.
Hope this helps you.
UIImagePickerController *imagePicker = [[UIImagePickerController alloc] init];
[imagePicker setSourceType:UIImagePickerControllerSourceTypeCamera];
[imagePicker setDelegate:self];
if ([self respondsToSelector:#selector(presentViewController:animated:completion:)])
{
[imagePicker setShowsCameraControls:NO];
[self presentViewController:imagePicker animated:YES completion:^{
[imagePicker setShowsCameraControls:YES];
}];
}
else
{
[imagePicker setShowsCameraControls:YES];
[self presentModalViewController:imagePicker animated:YES];
}
I am trying to select a picture from the device's photo library.
This is my code so far. I am following a tutorial and that should work, but I am getting an error :
"Use of undeclared identifier info", on the second method, line 3.
What am I doing wrong?
- (IBAction)selectPicturePressed:(UIButton *)sender {
UIImagePickerController *picker = [[UIImagePickerController alloc] init];
picker.delegate = self;
picker.allowsEditing = NO;
picker.sourceType = UIImagePickerControllerSourceTypePhotoLibrary;
[self presentViewController:picker animated:YES completion:NULL];
}
- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingImage:(UIImage *)img editingInfo:(NSDictionary *)editInfo
{
UIImage *chosenImage = [info objectForKey:#"UIImagePickerControllerOriginalImage"];
self.imgToUpload.image = chosenImage;
[picker dismissViewControllerAnimated:YES completion:NULL];
}
- (void)imagePickerControllerDidCancel:(UIImagePickerController *)picker {
[picker dismissViewControllerAnimated:YES completion:NULL];
}
Change info to editInfo will resolve it.
I can take a photo and it shows in imageviewn but as soon as I leave detailviewn and go to back to detailviewn its disappear. How should the image always be saved?
- (IBAction)takePhoto:(UIButton *)sender {
UIImagePickerController *picker = [[UIImagePickerController alloc] init];
picker.delegate = self;
picker.allowsEditing = YES;
picker.sourceType = UIImagePickerControllerSourceTypeCamera;
[self presentViewController:picker animated:YES completion:NULL];
}
- (IBAction)selectPhoto:(UIButton *)sender {
UIImagePickerController *picker = [[UIImagePickerController alloc] init];
picker.delegate = self;
picker.allowsEditing = YES;
picker.sourceType = UIImagePickerControllerSourceTypePhotoLibrary;
[self presentViewController:picker animated:YES completion:NULL];
}
- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info {
UIImage *chosenImage = info[UIImagePickerControllerEditedImage];
self.imageView.image = chosenImage;
[picker dismissViewControllerAnimated:YES completion:NULL];
}
- (void)imagePickerControllerDidCancel:(UIImagePickerController *)picker {
[picker dismissViewControllerAnimated:YES completion:NULL];
}
Check your IBOutlet Connection in xib file and You have to save the image taken in documents directory of your application , unless you cannot view the selected image
