Erase a subview

If I want to erase a subview, is it done w开发者_JAVA技巧hen I put mysubview.alpha = 0;? Or do I have to do anything else? Thank you!

If you just want to remove it do so using

[mySubview removeFromSuperview];

To "erase" a subview, just release it ;) It you put it's alpha value to 0, it is only hidden. As said in comment, you also have to remove it from superview ([myView removeFromSuperview]).

simply use:-

[*yoursubviewname* removeFromSuperView];
