i've tried below,but couldn't see on headerview.

nsdictionary *views2 = nsdictionaryofvariablebindings(label1, label2, label3);  [headerview addconstraints:[nslayoutconstraint constraintswithvisualformat:@"h:|-leftpadding-[label1]-0-[label2]-0-[label3]-rightpadding-|" options:0 metrics:@{@"leftpadding":[nsnumber numberwithint:15],@"rightpadding":[nsnumber numberwithint:15]} views:views2]];  [headerview addconstraint:[nslayoutconstraint constraintwithitem:label1                                                        attribute:nslayoutattributewidth                                                        relatedby:nslayoutrelationequal                                                           toitem:label2                                                        attribute:nslayoutattributewidth                                                       multiplier:1                                                         constant:0]];  [headerview addconstraint:[nslayoutconstraint constraintwithitem:label1                                                        attribute:nslayoutattributewidth                                                        relatedby:nslayoutrelationequal                                                           toitem:label3                                                        attribute:nslayoutattributewidth                                                       multiplier:1                                                         constant:0]];  [headerview addconstraint:[nslayoutconstraint constraintwithitem:label2                                                        attribute:nslayoutattributewidth                                                        relatedby:nslayoutrelationequal                                                           toitem:label3                                                        attribute:nslayoutattributewidth                                                       multiplier:1                                                         constant:0]];   [headerview addconstraints:[nslayoutconstraint constraintswithvisualformat:@"v:|[label1]|" options:0 metrics:nil views:views2]]; [headerview addconstraints:[nslayoutconstraint constraintswithvisualformat:@"v:|[label2]|" options:0 metrics:nil views:views2]]; [headerview addconstraints:[nslayoutconstraint constraintswithvisualformat:@"v:|[label3]|" options:0 metrics:nil views:views2]];

if want views have same width irrespective of distance between them. should use concept of spacer views. refer apple documentation more information on spacer views. think spacer best way go this. when have used spacers need apply constraints spacer views cause labels become equal in width.
