Question

我正在尝试更改自定义UITableViewCell中包含的UILabel的位置，但它不会移动。我启用了自动布局。

- (void)updateLayout
{
    NSArray* comp = [self.accessibilityHint componentsSeparatedByString:@"/"];
    if (comp.count > 1)
    {
    CGRect rect = _imageViewT.frame;
    rect.origin.x = 20 * comp.count;
    rect.size.width = 44.0;
    [_imageViewT setFrame:rect];
    [_imageConstraint setConstant:_imageViewT.frame.origin.x-8];

    rect = _lableT.frame;
    rect.origin.x = _imageViewT.frame.size.width+_imageViewT.frame.origin.x+8;
    rect.size.width = self.frame.size.width-rect.origin.x-40;
    [_lableT setFrame:rect];
    //[_imageConstraint setConstant:_imageViewT.frame.origin.x-8];


}
else
{
    CGRect rect = _imageViewT.frame;
    rect.origin.x = 10;
    rect.size.width = 43.0;
    [_imageViewT setFrame:rect];
    [_imageConstraint setConstant:2];

    rect = _lableT.frame;
    rect.origin.x = 62;
    rect.size.width = self.frame.size.width-rect.origin.x-40;
    [_lableT setFrame:rect];
}

}

我从cellForRowAtIndexPath调用update方法。 self.accessibilityHint包含字符串，如aa / bb / cc，aa / cc

Answer 1

UITableViewCell将在layoutSubviews:之后在 cellForRowAtIndexPath:中布置子视图，因此您的布局将在单元格的layoutSubviews中重置。您应该将布局代码从cellForRowAtIndexPath：移动到单元格的layoutSubviews。

Answer 2

设置label的autoresizingMask属性，我总是将它与单元格的子视图一起使用。

UILabel位置在UITableviewcell内不会改变
