ios - How can I apply multiplier to all my constraints created on nib files? -

i've pretty finished project, realize fonts , spaces in between weird in iphone 6plus.

i've created constraints drag , drop on xib files. colleague added these codes on global function can apply multipliers:

- (float)constraintscale {     if (is_standard_iphone_6_plus) {     return 1.29; } return 1.0;}  - (float)textscale {     if (is_standard_iphone_6_plus)    {     return 1.16;   } return 1.0; } 

my problem having drag each (more 100) constraints code , applying each these multiplier , scale. there more convenient way add multipliers xib files? i've thought subclassing take same amount of time?

self.view.constraints 

will give constraints on view.

for(nslayoutconstraint *c in self.view.constraints) {      c.multiplier = [self constraintscale]; } 

probably work. hope helps.

edit: sorry readonly issue. way rid of problem may be;

nsmutablearray *constraintsnew = [nsmutablearray new]; (nslayoutconstraint *c in self.view.constraints) {     nslayoutconstraint *newc = [nslayoutconstraint constraintwithitem:c.firstitem                                                             attribute:c.firstattribute                                                             relatedby:c.relation                                                                toitem:c.seconditem                                                             attribute:c.secondattribute                                                            multiplier:[self constraintscale]                                                              constant:c.constant];     [constraintsnew addobject:newc]; }  [self.view removeconstraints:self.view.constraints]; [self.view addconstraints:constraintsnew];
