如何刪除插圖中的UILabel iOS中

Question

我有文字d簡單的標籤和我使用sizeToFit我得到了高度21.5

不過我看填充約2px的

如何去除呢？

我嘗試layoutMargins = UIEdgeInsetsZero - 但沒有效果

Answer 1

你可能想嘗試繼承了UILabel和壓倒一切的drawTextInRect:有：

- (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];
