如何了解uiimagepicker中的图像拾取以及如何修改拾取图像或如何在图像拾取后调用？以及如何使用xcode for iphone将拾取图像作为下一个视图的背景图像？

Answer 1

您可以参考UIImagePickercontroller并使用UIImagePickerController的委托方法UIImagePickerDelegate

     - (void)imagePickerController:(UIImagePickerController  *)picker didFinishPickingMediaWithInfo:(NSDictionary  *)info
{
// Get the image picked by the image picker
UIImage *image = [info objectForKey:@"UIImagePickerControllerOriginalImage"];
//Do something
}

Answer 2

使用UIImagePickerController的委托方法：

- (void)imagePickerController:(UIImagePickerController *)pickerdidFinishPickingMediaWithInfo:(NSDictionary *)info {

   // Get the image picked by the image picker
   UIImage *image :[info objectForKey:@"UIImagePickerControllerOriginalImage"] ;
   //Do something
   [picker dismissModalViewControllerAnimated:YES];
}
