objective c - Constraints programatically and with Storyboards -


it possible set constraints programmatically , while using storyboards? using https://github.com/raphaelschaad/rsplaypausebutton constraints https://github.com/snapkit/masonry. not being displayed correctly: bad good

the image on left not being displayed correctly, , not clickable (it button).

relevant code:

- (void)viewdidload {      [super viewdidload];      _playpausebutton = [[rsplaypausebutton alloc] init];     _playpausebutton.tintcolor = [uicolor blackcolor];     [_playpausebutton addtarget:self action:@selector(playpausebuttondidpress:) forcontrolevents:uicontroleventtouchupinside];     [self.view addsubview:_playpausebutton];  }  - (void)viewdidlayoutsubviews {      [self.playpausebutton mas_makeconstraints:^(masconstraintmaker *make) {                 make.center.equalto(self.view).with.offset(10);             }];  }

you need adding width/height constraints playpausebutton, try this:

- (void)viewdidload {     [super viewdidload];      _playpausebutton = [[rsplaypausebutton alloc] init];     _playpausebutton.tintcolor = [uicolor blackcolor];     [_playpausebutton addtarget:self action:@selector(playpausebuttondidpress:) forcontrolevents:uicontroleventtouchupinside];     [self.view addsubview:_playpausebutton];      [playpausebutton mas_makeconstraints:^(masconstraintmaker *make) {         make.center.equalto(self.view).with.offset(10);         make.width.equalto(@(50));         make.height.equalto(@(50));     }]; }
