tableviewcell 中的水平 space 约束

Question

我在表格视图单元格中有标签如何将常量的值更新为 -65

我试过

[cell.address.leadingAnchor constraintEqualToAnchor:cell.address.leadingAnchor constant:-65].active = YES;

Answer 1

作为出风口需要拖拽

@property (weak, nonatomic) IBOutlet NSLayoutConstraint *leadCon;

然后改变它的常量

_leadCon.constant = -65;
[cell layoutIfNeeded];

Tip : What you currently do will add another constraint which will make a conflict between the 1 in IB , hence unexpected results
