i have menuviewcontroller , inside viewcontroller have 2 childviewcontrollers first 1 on left part , second 1 on right side.
view_width = self.view.frame.size.width; width_listtableview = 0.4; listviewcontroller *listviewcontroller = [[listviewcontroller alloc] init]; listnavigationviewcontroller *listviewnavigation = [[listnavigationviewcontroller alloc] initwithrootviewcontroller:listviewcontroller]; [self addchildviewcontroller:listviewnavigation]; [self.view insertsubview:listviewnavigation.view belowsubview:self.searchbarview.view]; [listviewnavigation didmovetoparentviewcontroller:self]; listviewnavigation.view.frame = cgrectmake(0, y, view_width*width_listtableview, height); previewviewcontroller *readviewcontroller = [[previewviewcontroller alloc] init]; [self addchildviewcontroller:readviewcontroller]; [self.view insertsubview:readviewcontroller.view belowsubview:listviewnavigation.view]; [readviewcontroller didmovetoparentviewcontroller:self]; readviewcontroller.view.frame = cgrectmake(listviewnavigation.view.frame.origin.x + listviewnavigation.view.frame.size.width, listviewnavigation.view.frame.origin.y, view_width - listviewnavigation.view.frame.size.width, listviewnavigation.view.frame.size.height); but cannot change frame of readviewcontroller , width , height (768.0, 1024.0).
i added constraint listviewnavigation, listviewnavigation.view.y = 0
- (void)addconstraintwithlistnavigationviewcontroller:(uiview *)listviewnavigation y:(cgfloat)y height:(cgfloat)height { //set x = 0; nslayoutconstraint *constrainttoanimate1 = [nslayoutconstraint constraintwithitem:listviewnavigation attribute:nslayoutattributeleft relatedby:nslayoutrelationequal toitem:self.view attribute:nslayoutattributeleft multiplier:0.00 constant:0]; [self.view addconstraint:constrainttoanimate1]; //set y = y; nslayoutconstraint *constrainttoanimate2 = [nslayoutconstraint constraintwithitem:listviewnavigation attribute:nslayoutattributetop relatedby:nslayoutrelationequal toitem:self.view attribute:nslayoutattributebottom multiplier:0.00 constant:y]; [self.view addconstraint:constrainttoanimate2]; //set width = self.view.frame.size.width*0.4 nslayoutconstraint *constrainttoanimate3 = [nslayoutconstraint constraintwithitem:listviewnavigation attribute:nslayoutattributewidth relatedby:nslayoutrelationequal toitem:self.view attribute:nslayoutattributewidth multiplier:width_listtableview constant:0.0]; [self.view addconstraint:constrainttoanimate3]; //set height = height nslayoutconstraint *constrainttoanimate4 = [nslayoutconstraint constraintwithitem:listviewnavigation attribute:nslayoutattributeheight relatedby:nslayoutrelationequal toitem:nil attribute:nslayoutattributenotanattribute multiplier:0.00 constant:height]; [self.view addconstraint:constrainttoanimate4]; }
this because have auto layout enabled. try update constraints after changing frame using function [readviewcontroller.view settranslatesautoresizingmaskintoconstraints:yes]
