裡面有詳細的說明，這的錯誤點是iOS6.0 SDK的原生錯誤，而此錯誤只會出現在不要旋轉模式的橫向App。以下是解決方法。
1. 沿用前一篇UIImagePickerController的例子，將方向設成橫向
2. 加入新的class檔，這是為了要避開原生的UIImagePickerController錯誤。
3. noRotationImagePicker.m上加入避開錯誤的程式碼
#import "noRotationImagePicker.h"
@interface noRotationImagePicker ()
@end
@implementation noRotationImagePicker
- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil
{
self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil];
if (self) {
// Custom initialization
}
return self;
}
- (void)viewDidLoad
{
[super viewDidLoad];
// Do any additional setup after loading the view.
}
- (void)didReceiveMemoryWarning
{
[super didReceiveMemoryWarning];
// Dispose of any resources that can be recreated.
}
- (BOOL)shouldAutorotate
{
return NO;
}
-(UIInterfaceOrientation)preferredInterfaceOrientationForPresentation
{
return UIInterfaceOrientationPortrait;
}
4. 在mainViewController.m上使用的地方，改成呼叫自己所改的Class
- (IBAction)openPhotoLibrary:(id)sender {
//UIView *anchor = sender;
UIImagePickerController *m_imagePicker = [[noRotationImagePicker alloc] init];
if ([UIImagePickerController isSourceTypeAvailable:
UIImagePickerControllerSourceTypePhotoLibrary]) {
m_imagePicker.wantsFullScreenLayout = YES;
m_imagePicker.sourceType = UIImagePickerControllerSourceTypePhotoLibrary;
m_imagePicker.delegate = self;
[m_imagePicker setAllowsEditing:YES]; // 圖片出現可編輯的選項
popover = [[UIPopoverController alloc] initWithContentViewController:m_imagePicker];
[popover setPopoverContentSize:CGSizeMake(300, 300)];
[popover presentPopoverFromRect:CGRectMake(0,0,300,300) inView:self.view permittedArrowDirections:UIPopoverArrowDirectionAny animated:YES]; // 此處popover的位置改成自定
}
}
- (IBAction)openPhotoAlbum:(id)sender {
UIView *anchor = sender;
UIImagePickerController *m_imagePicker = [[noRotationImagePicker alloc] init];
if ([UIImagePickerController isSourceTypeAvailable:
UIImagePickerControllerSourceTypeSavedPhotosAlbum]) {
m_imagePicker.sourceType = UIImagePickerControllerSourceTypeSavedPhotosAlbum;
m_imagePicker.delegate = self;
[m_imagePicker setAllowsEditing:YES];
popover = [[UIPopoverController alloc] initWithContentViewController:m_imagePicker];
[popover setPopoverContentSize:CGSizeMake(300, 300)];
[popover presentPopoverFromRect:anchor.frame inView:anchor.superview permittedArrowDirections:UIPopoverArrowDirectionAny animated:YES];
}
}
- (void) imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info
{
UIImage *image = [info objectForKey:UIImagePickerControllerOriginalImage];
[imageView setImage:image];
[popover dismissPopoverAnimated:YES]; // 使用正確的popover dismiss
}
