Question

I got this warning:

'UIView' may not respond to 'addSubview:withAnimation:'

The line of code which produce that warning is this:

[self.masterView addSubview:self.detailImage withAnimation:def];

And my relevant code is like this:

ExUIViewAnimationDefinition *def = [[ExUIViewAnimationDefinition alloc] init];
    def.type = ExUIAnimationTypeTransition;
    def.direction = ExUIAnimationDirectionMoveUp;
    [self.masterView addSubview:self.detailImage withAnimation:def];
    [def release];

I looked on the UIView documentation, i thought addSubview may be deprecated, but it still like this.

Does any one know how to solve this warning? Thanx in advance.

Answer 1

addSubview is a method UIView will respond to. addSubview:withAnimation: is not a method UIView will respond to.

If you want to add a subview with a fade or something like that, try this:

self.detailImage.alpha = 0.0;
[self.masterView addSubview:self.detailImage];

[UIView animateWithDuration:0.3 animations:^{
    self.detailImage.alpha = 1.0;
}];
