    NickyImagePickerViewController *pickerController = [[NickyImagePickerViewController alloc]init];
    pickerController.pickerDelegate = self;  //设置代理
    [self.navigationController presentViewController:pickerController animated:YES completion:nil];

- (void)nickyImagePicker:(NickyImagePickerViewController *)picker didSelectedImages:(NSArray *)imageArray{
    NSLog(@"%@",imageArray);    // imageArray子元素为UIImage对象
}
