Using -setFrame: is a key part of what my old code does, and that works fine with struts and springs. If these are translated to constraints, it may be that things work OK until I call -setFrame:, at which point it blows up. What I really want is that part of my view hierarchy to be free to use -setFrame:, but other parts use the autolayout constraints normally. The object is to avoid rewriting working code that has been functional for a decade, and so introducing a whole bunch of new bugs that will need a load of time to eliminate that I just don't have. There may be no general solution, but since the particular view is the content of a scroller, it might be possible to come up with a special case for this, because it seems constraints can't cross "scroller barriers", and that might therefore allow me to isolate the use of -setFrame: to this particular case. --Graham _______________________________________________ Cocoa-dev mailing list ([email protected]) Please do not post admin requests or moderator comments to the list.
