UITableViewCell自定义分隔符在滚动ios8期间消失
我已经搜索过了,但还没有找到解决方案,我有一个带有uitableviewcell的tableview。对于需要应用此自定义分隔符的单元格:UITableViewCell自定义分隔符在滚动ios8期间消失,ios,objective-c,uitableview,custom-cell,Ios,Objective C,Uitableview,Custom Cell,我已经搜索过了,但还没有找到解决方案,我有一个带有uitableviewcell的tableview。对于需要应用此自定义分隔符的单元格: UIView *lineView = [[UIView alloc] initWithFrame:CGRectMake(90, self.contentView.frame.size.height, 80, 1)]; lineView.backgroundColor = [UIColor lightGrayColor]; [self.contentView
UIView *lineView = [[UIView alloc] initWithFrame:CGRectMake(90, self.contentView.frame.size.height, 80, 1)];
lineView.backgroundColor = [UIColor lightGrayColor];
[self.contentView addSubView:lineView];
分隔符显示正确,现在,我不知道为什么如果我以中速上下滚动tableview,分隔符会在某些单元格上消失。我试着设定:
- (void)layoutSubviews
{
[super layoutSubviews];
UIView *lineView = [[UIView alloc] initWithFrame:CGRectMake(90, self.contentView.frame.size.height, 80, 1)];
lineView.backgroundColor = [UIColor lightGrayColor];
[self.contentView addSubview:lineView];
}
有什么建议吗?感谢
layoutSubviews
方法用于添加子视图是错误的,因为它调用了很多次。在awakeFromNib
方法中添加此子视图
另外,由于您使用的是self.contentView.frame.size.height
请尝试self.contentView.frame.size.height-1,因此您的行似乎超出了单元格
此外,试着在设备上测试它,有时模拟器也会有类似的图形错误。你还没有展示任何关于如何创建单元格的代码,但我会给出一个示例,例如,你可以这样做
//during initialisation
- (instancetype)initWithFrame:(CGRect)frame
{
self = [super initWithFrame:frame];
if(self)
{
[self setUpCell];
}
return self;
}
- (void)awakeFromNib
{
[self setUpCell];
}
//hear add the views only once
- (void)setUpCell
{
//hear add the all views
UIView *lineView = [[UIView alloc] initWithFrame:CGRectMake(90, self.contentView.frame.size.height - 1, 80, 1)];
lineView.backgroundColor = [UIColor greenColor];
lineView.tag = 123; //set its tag to access it in "layoutsubviews"
[self.contentView addSubview:lineView];
}
//this method may be called repeatedly, just set the frames of the subviews hear
- (void)layoutSubviews
{
[super layoutSubviews];
UIView *lineView = [self.contentView viewWithTag:123]; //get the subview with tag
lineView.frame = CGRectMake(90, self.contentView.bounds.size.height - 1,self.contentView.bounds.size.height - 1, 1);
}
您是否尝试过UIView*lineView=[[UIView alloc]initWithFrame:CGRectMake(90,self.contentView.frame.size.height-1,80,1)]?不要在layoutSubviews
方法中添加任何子视图,在初始化过程中添加视图,并在layoutSubviews
@ArbenPnishi中设置其框架谢谢我认为设置self.contentView.frame.size.height-1解决了我的问题!没有考虑到框架高度!
