iOS Delete AutoLayout

Sometimes, we need to dynamically change a value in the AutoLayout in view, such as moving the X-value, or the Y-value, what to do?

The following encapsulates a better way to remove: excerpt from Https://github.com/MakeZL/ZLAutoLayout (the framework that encapsulates AutoLayout)

The following is used to Zllayoutconstraint is an alias Nslayoutconstraint

typedef Nslayoutconstraint Zllayoutconstraint;

---------------

Remove all constraints

<span style= "FONT-SIZE:14PX;" > #pragma mark-remove view to Superview autolayout-(void) removeallautolayout{    [self removeconstraints: Self.constraints];    For (Zllayoutconstraint *constraint in self.superview.constraints) {        if ([Constraint.firstitem isequal:self]) {            [Self.superview removeconstraint:constraint];}}    </span>

---------------

Delete a single constraint

<span style= "FONT-SIZE:14PX;" > #pragma mark-remove single constraint-(void) Removeautolayout: (Zllayoutconstraint *) constraint{for    ( Zllayoutconstraint *constraint in self.superview.constraints) {        if ([constraint Isequal:constraint]) {            [ Self.superview removeconstraint:constraint];}}    } </span>

---------------

Delete multiple constraints

<span style= "FONT-SIZE:14PX;" > #pragma mark-remove constraints-(void) Removeautolayoutconstraints: (Nsarray *) constraints{for    ( Zllayoutconstraint *constraint in constraints) {for        (Zllayoutconstraint *superviewconstraint in self.superview.constraints) {            if ([Superviewconstraint Isequal:constraint]) {                [Self.superview Removeconstraint:constraint];}}}    </span>

I wish you all a happy!
