it looks like that didn't help. maybe i've made a mistake with the size
constraints, or maybe there's something else wrong.
i have a method that calculates the required height for the subview. here's the
code i added to that method:
[self setFrameSize:NSMakeSize(width, height)];
if (heightConstraint) {
[self removeConstraint:heightConstraint];
heightConstraint = nil;
}
if (widthConstraint) {
[self removeConstraint:widthConstraint];
widthConstraint = nil;
}
heightConstraint = [NSLayoutConstraint constraintWithItem:self
attribute:NSLayoutAttributeHeight
relatedBy:NSLayoutRelationEqual
toItem:nil
attribute:NSLayoutAttributeNotAnAttribute
multiplier:1
constant:height];
[self addConstraint:heightConstraint];
widthConstraint = [NSLayoutConstraint constraintWithItem:self
attribute:NSLayoutAttributeWidth
relatedBy:NSLayoutRelationEqual
toItem:nil
attribute:NSLayoutAttributeNotAnAttribute
multiplier:1
constant:width];
[self addConstraint:widthConstraint];
did i screw up? wouldn't surprise me, since this is my first project where i
use constraints in code…
come to think of it, should i add the constraints to the superview instead of
self? gonna try that...
