如何添加按钮＆ldquo;上传＆rdquo;在Iphone中使用相机时？

- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {


//do actions
UIImagePickerController *picker = [[UIImagePickerController alloc] init];

// Set the image picker source to the camera:
picker.sourceType = UIImagePickerControllerSourceTypeCamera;

// Hide the camera controls:
picker.showsCameraControls = YES;
picker.navigationBarHidden = NO;

// Make the view full screen:
picker.wantsFullScreenLayout = YES;
//picker.cameraViewTransform = CGAffineTransformScale(picker.cameraViewTransform, CAMERA_TRANSFORM_X, CAMERA_TRANSFORM_Y);

// Now insert our overlay view (it has to be here cuz it's a modal view):
//picker.cameraOverlayView = overlayView;

matches *aMatch = [appDelegate.matches objectAtIndex:indexPath.row];
NSLog(@"%@", [NSString stringWithFormat:@"%d", aMatch.match_id]);

// Show the picker:
[self presentModalViewController:picker animated:YES];


[picker release];
