你也可以用一个自定义框架初始化你的UILabel来解决这个问题。

    CGRect initialFrame = CGRectMake(0, 0, 100, 100);
    UIEdgeInsets contentInsets = UIEdgeInsetsMake(0, 10, 0, 0);
    CGRect paddedFrame = UIEdgeInsetsInsetRect(initialFrame, contentInsets);

    self.label = [[UILabel alloc] initWithFrame:paddedFrame];

向CGRect Tricks致敬。

和@IBDesignable，使其与接口生成器一起工作

编辑:这个真的很老了。上面有更好的解决方案。

我最终只是在文本中添加了一些空格:

self.titleLabel.text = [NSString stringWithFormat:@"    %@", self.titleLabel.text];

丑陋但有效，不需要子类化。

你也可以试试“\t”。对于一般的解决方案，请参考已接受的答案

这是我发现的最简单的方法。这对我来说很有魔力。

UIView *titleSection = [[UIView alloc] initWithFrame:CGRectMake(0, 0, screenWidth, 100)];
[titleSection addSubview:titleSection];

UILabel *label = [[UILabel alloc] initWithFrame:CGRectInset(titleSection.frame, PADDING, 0)];
[titleSection addSubview:label];

没有子类和所有的爵士。我动态地做了这个:

[cell.textLabel setTranslatesAutoresizingMaskIntoConstraints:NO];
[cell.textLabel constraintTrailingEqualTo:cell.contentView constant:-100];

约束部分只是一个简单的代码糖纸(我们有相同的方法从上/下/左/右添加填充)..如果我在这里得到足够的爱，我将开放整个包装:

- (id)constraintTrailingEqualTo:(UIView *)toView constant:(CGFloat)constant
{
    NSLayoutConstraint *cn = [NSLayoutConstraint constraintWithItem:self
                                                          attribute:NSLayoutAttributeTrailing
                                                          relatedBy:NSLayoutRelationEqual
                                                             toItem:toView
                                                          attribute:NSLayoutAttributeTrailing
                                                         multiplier:1 constant:constant];

    [toView addConstraint:cn];
    return self;
}

(注意，我是在

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath: (NSIndexPath *)indexPath;

你可能需要调用[self setNeedsLayout];这取决于你的语境。

可以使用https://github.com/mattt/TTTAttributedLabel代替UILabel

BITAttributedLabel *label = [BITAttributedLabel new];
label.font = font;
label.text = @"hello";
label.textInsets = UIEdgeInsetsMake(10, 10, 10, 10);
[label sizeToFit];
