-(void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info
{
UIImage *tempImage = [info objectForKey:UIImagePickerControllerOriginalImage];
imgview.image = tempImage;
[self dismissModalViewControllerAnimated:YES];
[picker release];
}
-(void)imagePickerControllerDidCancel:(UIImagePickerController *)picker
{
[self dismissModalViewControllerAnimated:YES];
[picker release];
}
-(IBAction) calllib
{
img1 = [[UIImagePickerController alloc] init];
img1.delegate = self;
img1.sourceType = UIImagePickerControllerSourceTypePhotoLibrary;
[self presentModalViewController:img1 animated:YES];
}
all the codes above works well for taking out photos from the photo library.
problem is that when i tried to use it under the UIActionSheet it does not work.
i just copy the lines of codes from the -(IBAction) calllib as follow.
- (void)actionSheet:(UIActionSheet *)actionSheet clickedButtonAtIndex:(NSInteger)buttonIndex
{
UIImage *detectface = [Utilities detectFace:imgview.image];
UIImage *grayscale = [Utilities grayscaleImage:imgview.image];
UIImage *avatars = [Utilities avatars:imgview.image];
img1 = [[UIImagePickerController alloc] init];
img1.delegate = self;
img1.sourceType = UIImagePickerControllerSourceTypePhotoLibrary;
switch (buttonIndex)
{
case 0:
[self presentModalViewController:img1 animated:YES];
imgview.image = detectface;
break;
case 1:
[self presentModalViewController:img1 animated:YES];
imgview.image = grayscale;
break;
case 2:
[self presentModalViewController:img1 animated:YES];
imgview.image = avatars;
break;
default:
break;
}
}
它不起作用。有人能幫我弄清楚是什麼問題?如何使UIImagePickerController在開關盒下工作UIActionSheet
沒有[self presentModalViewController:img1 animated:YES]; switch case可以正常工作; ...
感謝

開關櫃的作品!但只有當我在UIImage上有圖像。現在的問題是,在我選擇了一個案例之後,代碼看起來像是在同一時間一起運行。它會改變圖像,然後只會去照片庫。 – Phy 2011-01-08 13:07:11
