iOS 实现 presentViewController:界面，

TZImagePickerController *imagePickController = [[TZImagePickerController alloc] initWithMaxImagesCount:self.maxImageSelected delegate:self];
   *** 这句的代码是关键 *** 
   *** imagePickController.modalPresentationStyle = UIModalPresentationFullScreen;***
    [self.currentViewController presentViewController:imagePickController animated:YES completion:nil];
}
