ios - UIView autoresizingMask 在设置不同的固定左右边距和灵活宽度时出现错误？

Question

我正在尝试使用该代码创建一个带有左插入分隔符的 View (如 iOS 7 中的表格 View 单元格):

UIView *container = [[UIView alloc] initWithFrame:CGRectMake(0.0f, 0.0f, 500.0f, 90.0f)];
container.backgroundColor = [UIColor whiteColor];
container.autoresizingMask = UIViewAutoresizingFlexibleWidth;
container.layer.cornerRadius = 5.0f;
container.layer.borderColor = grayColor.CGColor;
container.layer.borderWidth = 1.0f;
NSLog(@"container: %@", NSStringFromCGRect(container.bounds));

UIView *separator = [[UIView alloc] initWithFrame:CGRectMake(13.0f, floorf(container.height / 2), container.width - 13.0f, 1.0f)];
separator.backgroundColor = grayColor;
separator.autoresizingMask = UIViewAutoresizingFlexibleWidth | UIViewAutoresizingFlexibleTopMargin | UIViewAutoresizingFlexibleBottomMargin;
[container addSubview:separator];
NSLog(@"separator: %@", NSStringFromCGRect(separator.frame));

如您所见，我将容器的宽度明确设置为 500 像素。然而，后来它变成了 258px。结果我得到的是:

我应该怎么做才能去掉分隔符右边多余的部分？当容器的宽度为 500px 时，我的 autoresizingMask 看起来是正确的:

尝试一下

separator.autoresizingMask = UIViewAutoresizingFlexibleRightMargin | UIViewAutoresizingFlexibleWidth | UIViewAutoresizingFlexibleWidth | UIViewAutoresizingFlexibleWidth | UIViewAutoresizingFlexibleWidth UIViewAutoresizingFlexibleTopMargin | UIViewAutoresizingFlexibleTopMargin | UIViewAutoresizingFlexibleTopMargin | UIViewAutoresizingFlexibleTopMargin UIViewAutoresizingFlexibleBottomMargin;
