问题描述
I load a UIImageView with an image depending on user interaction. When the parent view is initially displayed, no image has been selected and the imageview is black. If the user leaves that view and comes back, the image is still there. I've tried
myImageView.image = nil;
upon leaving the view but the image remains. How can I remove the image so the UIImageView appears black again?
The
is connected through IB.
解决方案
Setting the UIImageView as:
myImageView.image = nil
is the correct way to clear an UIImageView. Are you loading the image when your calling function returns? Is your UIImageView being declared, and/or used elsewhere in your main function?
