ios - UILabel 以编程方式添加，在 iphone 6 上显示模糊文本

Question

int dx = (int)CGRectGetMaxX(coverView.frame)+10;
int dy = (int)self.frame.size.width-CGRectGetMaxX(coverView.frame)-5;
titleView = [[UILabel alloc] initWithFrame:CGRectMake(dx, padding,dy , 20)];
titleView.center = [self roundedCenterPoint:titleView.center];
[titleView setBackgroundColor:[UIColor clearColor]];
[titleView setTextColor:[UIColor blackColor]];
[titleView setFont:[UIView yoda_fontWithType:YODA_FONT_TABLEVIEWCELL_TITLE]];
titleView.numberOfLines = 0;
titleView.opaque = YES;
titleView.autoresizingMask = UIViewAutoresizingFlexibleWidth;

然后在创建后将其添加到 UIatbleviewCell

 [self addSubview:titleView];

此方法设置文本并通过标签框架上的类别设置

 -(void) setTitle:(NSString*)title
{
    [titleView setText:title];
    [titleView setVerticalAlignmentTop];
}

圆心点

-(CGPoint)roundedCenterPoint:(CGPoint) pt {
  return CGPointMake(round(pt.x), round(pt.y));
 }

UIlabel分类方法

- (void) setVerticalAlignmentTop
{
     CGSize textSize = [self.text sizeWithFont:self.font
                        constrainedToSize:self.frame.size
                            lineBreakMode:self.lineBreakMode];

    CGRect textRect = CGRectMake(self.frame.origin.x,
                             self.frame.origin.y,
                             self.frame.size.width,
                             ceilf(textSize.height));

    [self setFrame:CGRectIntegral(textRect)];
    [self setNeedsDisplay];
}

这一行的第一个

titleView.autoresizingMask = UIViewAutoresizingFlexibleWidth;

像这样添加UIViewAutoresizingFlexibleHeight

titleView.autoresizingMask = UIViewAutoresizingFlexibleWidth | UIViewAutoresizingFlexibleHeight;

第二次增加标签的高度，例如当前设置的 20 使其变为 30 并检查。
