UICollectionViewCell 边框多一条线

直接上图,红圈内多出来的一条诡异的黑线
并不是每个Cell都会有,也不是每次都会出现

到现在也还没有找到问题到底出在哪里
公司项目紧,搁置了好几天没去理会
- (id)initWithFrame:(CGRect)frame
{
self = [super initWithFrame:frame];
if (self) {
_label = [[UILabel alloc] initWithFrame:self.bounds];
_label.backgroundColor = [UIColor colorWithRed:0.94 green:0.94 blue:0.94 alpha:1.00];
_label.font = [UIFont systemFontOfSize:14];
_label.textAlignment = NSTextAlignmentCenter;
_label.textColor = [UIColor colorWithRed:0.33 green:0.33 blue:0.33 alpha:1.00];
[self.contentView addSubview:_label];
}
return self;
}
今天抽出来点时间研究了一下
- (id)initWithFrame:(CGRect)frame
{
self = [super initWithFrame:frame];
if (self) {
_label = [[UILabel alloc] initWithFrame:CGRectIntegral(self.bounds)];
_label.backgroundColor = [UIColor colorWithRed:0.94 green:0.94 blue:0.94 alpha:1.00];
_label.font = [UIFont systemFontOfSize:14];
_label.textAlignment = NSTextAlignmentCenter;
_label.textColor = [UIColor colorWithRed:0.33 green:0.33 blue:0.33 alpha:1.00];
[self.contentView addSubview:_label];
}
return self;
}

居然,解决了...
上代码
_label = [[UILabel alloc] initWithFrame:self.bounds];
_label = [[UILabel alloc] initWithFrame:CGRectIntegral(self.bounds)];
CGRectIntegral()
这个函数可以将小数类型的值转为整型
frame的数值为小数时,像素渲染到屏幕上时会产生奇怪的黑影,就是那条诡异的黑线产生的原因
CGRectIntegral() 将frame的值都转为整型时,这个问题就被解决了
小白总结,欢迎打脸指正
