Ios 如何根据uiimageview的标记值属性在其上添加图像。？

我在uiimageview点击事件中打开了一个摄像头，希望根据点击的图像添加摄像头图像。在我看来，我有四个形象。每个imageview将分别打开相机。看看我的代码

步骤1

为手势指定相同的方法名称

步骤2

获取标签并将标签传递给imagepickercontroller

步骤3

根据标记设置最终图像

什么是第一个和第二个…这些是图像名称，先生，我的视图中有四个图像什么是第一个和第二个…这些是图像名称，先生，我的视图中有四个图像，先生，这样的标记会给我错误，例如“在uiimagePickerController类型的对象上找不到属性标记”，您在哪一行看到了这一个，先生“picker.tag=tabbedIamage.tag；“它应该类似于

picker.view.tag

您不能将标记设置为viewcontrollerYa bro我知道imagepicker没有任何标记属性bro，很抱歉我修改了我的回答sir它给我这样的标记错误“在uiimagePickerController类型的对象上找不到属性标记”，您在哪一行看到这个sir”picker.tag=tabbedIamage.tag；“它应该像

picker.view.tag

你不能将tag设置为viewcontrollerYa bro我知道了imagepicker没有任何标记属性bro，很抱歉我修改了我的答案
