iOS 如何更改Cell中默认accessoryView的位置

Posted 2022-12-03 阿曌

如果你不想自定义Cell，又希望改变accessoryView的位置的话，很简单，在子Cell类中的layoutSubviews方法中去修改accessoryView的frame。(别忘了调用[super layoutSubviews])

- (void)layoutSubviews

    [super layoutSubviews];

    CGRect adjustedFrame = self.accessoryView.frame;
    adjustedFrame.origin.x += 10.0f;
    self.accessoryView.frame = adjustedFrame;

直接在别的位置修改是没有效果的！~

如果不希望子类化Cell，还有个“作假”的办法，就是把accessoryView里面塞进去的view宽度变大，然后调整对内对齐方式。

static CGFloat const kRightOffset = 10.0;

cell.accessoryView = (UIImageView * imgV = [[UIImageView alloc]initWithImage:[UIImage imageNamed:@"image.png"]];
                CGRect frame = imgV.frame;
                frame.size.width = frame.size.width + kRightOffset;
                imgV.frame = frame;
                [imgV setContentMode:UIViewContentModeLeft];
                imgV; );

该方法是我试验是能够得到效果是往左移，往右移的办不到（估计默认给cell.accessoryView加了右边的margin）
