#pragma mark -
#pragma mark UIImagePickerControllerDelegate

- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingImage:(UIImage *)image editingInfo:(NSDictionary *)editingInfo
{
    NSLog(@"image picker method called");
    // Dismiss the image selection, hide the picker and show the image view with the picked image
    [imagePickerController dismissModalViewControllerAnimated:YES];
    //imagePickerController.view.hidden = YES;


    CGRect frame = CGRectMake(40, 5, 200, 200);
    UIImageView *imageView = [[UIImageView alloc] initWithFrame:frame];
    imageView.image = image;
    imageView.hidden = NO;
    [self.view addSubview: imageView];
    [self.view addSubview: messageText];
    [self.view addSubview: sendGreet];
    [fromGallery removeFromSuperview];
    [fromCamera removeFromSuperview];

}

我，您的方法-(void) getImageAction:(id) sender最后添加[imagePickerController release];。当你使用presentModalViewController时，你必须释放你要移动的控制器。

通常，当存在内存泄漏或未知标识符发送到某个方法时，应用程序崩溃。

希望这对你有用!!
