I have the following code
// Breakpoint here
[label removeFromSuperview];
[label release];
label = nil;
stepping through it with the debugger outputs
(gdb) po [self subviews]
<NSCFArray 0x476af70>(
<UIImageView: 0x47581a0; frame = (0 0; 232 81); opaque = NO; autoresize = W+H; userInteractionEnabled = NO; layer = <CALayer: 0x476b3d0>>,
<UILabel: 0x4758870; frame = (15 11; 202 56); text = 'Test'; clipsToBounds = YES; autoresize = W+H; userInteractionEnabled = NO; layer = <CALayer: 0x476b590>>
)
(gdb) po label
<UILabel: 0x4758870; frame = (15 11; 202 56); text = 'Test'; clipsToBounds = YES; autoresize = W+H; userInteractionEnabled = NO; layer = <CALayer: 0x476b590>>

<NSCFArray 0x478c4e0>(
<UIImageView: 0x47581a0; frame = (0 0; 232 81); opaque = NO; autoresize = W+H; userInteractionEnabled = NO; layer = <CALayer: 0x476b3d0>>
)
Yet it is still visible, it does not disappear. Not even if I do [self setNeedsDisplay] immediately after.
Has anyone else come across this? Is it a bug in the SDK or am I missing something?
