如何在iOS中删除UILabel中的insets

Question

我有简单的标签与文本D和我使用sizeToFit我得到高度21.5

但我看到填充大约2px

如何删除它？

我尝试layoutMargins = UIEdgeInsetsZero - 但没有效果

Answer 1

您可能想尝试子类化UILabel并覆盖drawTextInRect: with：

- (void)drawTextInRect:(CGRect)rect
{
    [super drawTextInRect:UIEdgeInsetsInsetRect(rect, UIEdgeInsetsMake(0., 0., 0., 0.))];
}

Answer 2

CGRect frame = CGRectMake(0, 0, 120, 30);
UIEdgeInsets contentInsets = UIEdgeInsetsMake(0, 0, 0, 0);
CGRect labelFrame = UIEdgeInsetsInsetRect(frame, contentInsets);
UILabel *label = [[UILabel alloc] initWithFrame:labelFrame];
