照片选取器和照相机的iPad

Question

我有编码从照片库或从最适合iPhone的照相机附加文件。但对于iPAD，我开始知道必须使用popUpViewController。任何人都可以建议在iPad上附加图片的代码？

而且我的代码里面酥料饼

-(void)openCamera 
{ 
@try 
{ 
     UIImagePickerController *picker = [[UIImagePickerController alloc] init]; 
     picker.delegate = self; 
     picker.sourceType = UIImagePickerControllerSourceTypeCamera; 
     picker.navigationBar.tintColor = [UIColor blackColor]; 
     [self.navigationController presentViewController:picker animated:YES completion:nil]; 



} 
@catch (NSException *exception) 
{ 
    CustomAlertView *alert = [[CustomAlertView alloc] initWithTitle:@"No Camera" 
                  message:@"Camera is not available " 
                  delegate:self cancelButtonTitle:@"Ok" 
                otherButtonTitles:nil]; 
    [alert show]; 

} 
} 

-(void)pick 
{ 
UIImagePickerController *picker = [[UIImagePickerController alloc] init]; 
picker.delegate = self; 
picker.sourceType = UIImagePickerControllerSourceTypePhotoLibrary; 
picker.navigationBar.tintColor = [UIColor blackColor]; 
[self presentViewController:picker animated:YES completion:nil]; 

} 

- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info 
{ 

if (picker.sourceType == UIImagePickerControllerSourceTypeCamera) 
{ 

    [picker dismissViewControllerAnimated:YES completion:nil]; 

    UIImage *fullImage = (UIImage *) [info objectForKey:UIImagePickerControllerOriginalImage]; 

    UIImage *thumbImage = [fullImage imageByScalingAndCroppingForSize:CGSizeMake(180,180)]; 
    self.detailItem.fullImage = fullImage; 
    self.detailItem.thumbImage = thumbImage; 

    NSData *dataObj = UIImagePNGRepresentation(thumbImage); 
    base64String=[dataObj base64Encoding]; 

    NSDate *currentDateTime = [NSDate date]; 
    NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init]; 
    [dateFormatter setDateFormat:@"MMddyyyy_HHmmss"]; 
    NSString *dateInStringFormated = [dateFormatter stringFromDate:currentDateTime]; 

    fileName = [NSString stringWithFormat:@"IMG_%@.png",dateInStringFormated]; 

    [self Uploadfile]; 
} 
else 
{ 
    [picker dismissViewControllerAnimated:YES completion:nil]; 

    UIImage *fullImage = (UIImage *) [info objectForKey:UIImagePickerControllerOriginalImage]; 


    UIImage *thumbImage = [fullImage imageByScalingAndCroppingForSize:CGSizeMake(180,180)]; 
    self.detailItem.fullImage = fullImage; 
    self.detailItem.thumbImage = thumbImage; 

    NSData *dataObj = UIImagePNGRepresentation(thumbImage); 
    base64String=[dataObj base64Encoding]; 

    NSURL *imageURL = [info valueForKey:UIImagePickerControllerReferenceURL]; 
    ALAssetsLibraryAssetForURLResultBlock resultblock = ^(ALAsset *myasset) 
    { 
     ALAssetRepresentation *representation = [myasset defaultRepresentation]; 
     fileName = [representation filename]; 
     NSLog(@"fileName siva : %@",fileName); 
     [self Uploadfile]; 

    }; 

    ALAssetsLibrary* assetslibrary = [[ALAssetsLibrary alloc] init]; 
    [assetslibrary assetForURL:imageURL 
        resultBlock:resultblock 
        failureBlock:nil];  



} 


} 

Answer 1

用户图像选择器。

UIPopoverController *popover = [[UIPopoverController alloc] initWithContentViewController:picker]; 

Answer 2

试试这个

UIImagePickerController *imagePickerController= [[UIImagePickerController alloc]init]; 
[imagePickerController setSourceType:UIImagePickerControllerSourceTypePhotoLibrary]; 
[imagePickerController setDelegate:self]; 
self.popoverPickerController = [[UIPopoverController alloc] initWithContentViewController:imagePickerController]; 
[self.popoverPickerController presentPopoverFromRect:CGRectMake(0,0,100,100) inView:[self teilnehmerCollectionView] permittedArrowDirections:UIPopoverArrowDirectionAny animated:YES];
