ios - Masonry.unrecognized 选择器发送到实例

Question

  UIView *v2 = ({
        UIView *view = [UIView new];
        [self.view addSubview:view];
        [view mas_makeConstraints:^(MASConstraintMaker *make) {
            make.size.mas_equalTo(CGSizeMake(50, 50));
            make.left.equalTo(v1.mas_right);
            make.top.equalTo(v1.mas_bottom);
        }];
        view.backgroundColor = [UIColor blueColor];
        view.layoutMargins = UIEdgeInsetsMake(-20, -20, -20, -20);
        view;
    });


     UIView *v3 = ({
        UIView *view = [UIView new];
        [self.view addSubview:view];
        [view mas_makeConstraints:^(MASConstraintMaker *make) {
            make.size.mas_equalTo(CGSizeMake(50, 50));
            make.centerY.equalTo(v2);
            make.left.equalTo(v2.mas_rightMargin);
//            make.left.equalTo(v2.mas_right);
        }];
        view.backgroundColor = [UIColor redColor];
        view;
    });

如您所见，我正在使用 Masonry 来创建 UI。

这段代码有错误。

-[UIView mas_rightMargin]: unrecognized selector sent to instance 0x7fdfa640cf80'

如果我将 make.left.equalTo(v2.mas_rightMargin); 更改为 make.left.equalTo(v2.mas_right);;，它不会崩溃。

只需将 Pods -> Masonry -> iOS Deployment Target 设置为您项目的目标即可。这是截图，希望对你有帮助...
