ios - How to get tableviwe to fit content using autolayout -

im rting figure out how tableviews height change depending upon content in tableview. cant allow tablevoew go further bounds of superview. can have tableview anywhere in between bounds of superview, can shrink grow other stuff depending upon content. did set top, leading , trailing constraints left botton constraint out thinking scale tableview needed height didint work. idea?

this have written im trying figure out bottom costraint should in order allow tableview grow contents size

you can have @ answer: https://stackoverflow.com/a/13574193/2082569

pasting solution here easy reference, calculating height of cells , setting tableview's frame-

cgfloat tableheight = 0.0f; (int = 0; < [_stepsarray count]; ++) {     tableheight += [self tableview:self.tableview heightforrowatindexpath:[nsindexpath indexpathforrow:i insection:0]]; } self.tableview.frame = cgrectmake(self.tableview.frame.origin.x, self.tableview.frame.origin.y, self.tableview.frame.size.width, tableheight); 

the thing thats missing don't want go beyond superview's bounds, can use min method this-

min(self.view.frame.size.height, tableheight); 

optionally can checkout answer, uses sizetofit approach: https://stackoverflow.com/a/24202699/2082569

hope helps.
