Make this work for iPad as well? - iphone

Question

How to make this work for iPad as well? it works fine on iphone but Apple requires that all apps should work on ipad. any help with this?
- (IBAction)chooseImage:(id)sender
{
self.imagePicker = [[UIImagePickerController alloc] init];
self.imagePicker.delegate = self;
[self.imagePicker setSourceType:UIImagePickerControllerSourceTypePhotoLibrary];
[self presentViewController:self.imagePicker animated:YES completion:nil];
}
- (void) imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info
{
self.image = info[UIImagePickerControllerOriginalImage];
[self.imageView setImage:self.image];
[self dismissViewControllerAnimated:YES completion:nil];
}
- (void) imagePickerControllerDidCancel:(UIImagePickerController *)picker
{
[self dismissViewControllerAnimated:YES completion:nil];
}
Now I've got this far! It doesn't crash anymore now when I pick an image from the photo library using the ipad. The problem is that the image doesn't get picked?
Any suggestions?
- (IBAction)chooseImage:(id)sender
{
self.imagePicker = [[UIImagePickerController alloc] init];
self.imagePicker.delegate = self;
[self.imagePicker setSourceType:UIImagePickerControllerSourceTypePhotoLibrary];
if (UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPad){
_popover = [[UIPopoverController alloc] initWithContentViewController:_imagePicker];
_popover.delegate = self;
[_popover setPopoverContentSize:CGSizeMake(320, 460)];
[_popover presentPopoverFromBarButtonItem:[[UIBarButtonItem alloc]initWithCustomView:(UIButton*)sender] permittedArrowDirections:UIPopoverArrowDirectionAny animated:YES];
}
[self presentViewController:self.imagePicker animated:YES completion:nil];
}
- (void) imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info
{
if
(self.popover && self.popover.popoverVisible) {
[self.popover dismissPopoverAnimated:YES];
}
else
self.image = info[UIImagePickerControllerOriginalImage];
[self.imageView setImage:self.image];
[self dismissViewControllerAnimated:YES completion:nil];
}
- (void) imagePickerControllerDidCancel:(UIImagePickerController *)picker
{
[self dismissViewControllerAnimated:YES completion:nil];
}

Here's the section from my book on UIImagePickerController:
http://www.apeth.com/iOSBook/ch30.html#_uiimagepickercontroller
Okay, sorry, no universal code. But it works just the same way architecturally as for MPMediaPickerController, for which I do give code showing how to do it on both iPhone and iPad:
http://www.apeth.com/iOSBook/ch29.html#EXmodalOrPop
It's tricky because popover management is very different from presented view controller management. That code shows you some of what you have to worry about...
Here is actual code from a universal app I just wrote:
- (IBAction)doPickAPicture:(id)sender {
UIImagePickerControllerSourceType type = UIImagePickerControllerSourceTypePhotoLibrary;
BOOL ok = [UIImagePickerController isSourceTypeAvailable:type];
if (!ok) {
return;
}
UIImagePickerController* picker = [UIImagePickerController new];
picker.sourceType = type;
picker.mediaTypes = #[(__bridge NSString*)kUTTypeImage];
picker.delegate = self;
if (UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPhone)
[self presentViewController:picker animated:YES completion:nil];
else {
UIPopoverController* pop = [[UIPopoverController alloc] initWithContentViewController:picker];
[pop presentPopoverFromRect:[sender bounds] inView:sender permittedArrowDirections:UIPopoverArrowDirectionAny animated:YES];
self.currentPop = pop;
}
}
-(void)imagePickerControllerDidCancel:(UIImagePickerController *)picker {
[self dismissViewControllerAnimated:YES completion:nil];
}
-(void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info {
if (self.currentPop && self.currentPop.popoverVisible) {
[self.currentPop dismissPopoverAnimated:YES];
} else {
[self dismissViewControllerAnimated:YES completion:nil];
}
[CATransaction setCompletionBlock:^{
self.currentPop = nil;
// do more stuff
}];
}
