重写UITableViewCell子类的layoutSubviews方法

使用Objective-C

- (void)layoutSubviews {    [super layoutSubviews];    for (UIView *subview in self.contentView.superview.subviews) {        if ([NSStringFromClass(subview.class) hasSuffix:@"SeparatorView"]) {            subview.hidden = NO;            CGRect frame = subview.frame;            frame.origin.x += self.separatorInset.left;            frame.size.width -= self.separatorInset.right;            subview.frame =frame;        }    }}

使用Swift

override func layoutSubviews() {    super.layoutSubviews()    for item in self.contentView.superview!.subviews {    var subview = item as! UIView    if NSStringFromClass(subview.classForCoder).hasSuffix("SeparatorView") {        subview.hidden = false            var frame = subview.frame            frame.origin.x += self.separatorInset.left            frame.size.width -= self.separatorInset.right            subview.frame  = frame        }    }}
