次のコードを使用した場合にのみiPadでエラー/クラッシュが発生します。iPhoneは正常に動作します。
基本的には、ギャラリーを読み込んで画像を選択しようとするときです。
デバッグエラーは次のとおりです。「iPadでは、UIImagePickerControllerはUIPopoverControllerを介して提示する必要があります」
-(void) actionSheet:(UIActionSheet *)actionSheet clickedButtonAtIndex:(NSInteger)buttonIndex{
if (buttonIndex == 0) {
if ([UIImagePickerController isSourceTypeAvailable:UIImagePickerControllerSourceTypePhotoLibrary]) {
UIImagePickerController *picker = [[UIImagePickerController alloc] init];
picker.delegate = self;
picker.sourceType = UIImagePickerControllerSourceTypePhotoLibrary;
[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:@"Abort!"
otherButtonTitles:nil];
[alert show];
[alert release];
}
}
if (buttonIndex == 1) {
if ([UIImagePickerController isSourceTypeAvailable:UIImagePickerControllerSourceTypeCamera]) {
UIImagePickerController *picker = [[UIImagePickerController alloc] init];
picker.delegate = self;
picker.allowsEditing = YES;
picker.sourceType =UIImagePickerControllerSourceTypeCamera;

UIImage *image2=[info objectForKey:UIImagePickerControllerEditedImage];

//imageData = UIImagePNGRepresentation(myscaledImage);

}
else {

//UIImage *myscaledImage=[self scaleImage:image toSize:CGSizeMake(18, 24)];
//imageData = UIImagePNGRepresentation(myscaledImage);
imageData=UIImageJPEGRepresentation(image, .6);
NSLog(@"the lenght of the image dataa is %d",[imageData length]);
}

上記のコードを手伝ってくれる人はいますか？if / elseステートメントを推測していますが、それが何であり、どこに配置するかについての最初の考えはありません。
前もって感謝します、
クリス
編集-OKこれでギャラリーからの読み込みが機能するようになりました小さなウィンドウに「写真」が読み込まれます。ここで選択できますが、「選択」または「選択」ボタンはありません。写真をクリックしてもチェックマークはありません、選択されていると言うと、それは選択されますが、閉じるにはウィンドウの外側をクリックします...それで機能しますが、何かを見逃していると思います。ここにコードがあります。
