也许过会儿再去派对，但下面的就行了。只是UILabel的子类。

#import "UITagLabel.h"

#define padding UIEdgeInsetsMake(5, 10, 5, 10)

@implementation UITagLabel

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

- (CGSize) intrinsicContentSize {
    CGSize superContentSize = [super intrinsicContentSize];
    CGFloat width = superContentSize.width + padding.left + padding.right;
    CGFloat height = superContentSize.height + padding.top + padding.bottom;
    return CGSizeMake(width, height);
}

- (CGSize) sizeThatFits:(CGSize)size {
    CGSize superSizeThatFits = [super sizeThatFits:size];
    CGFloat width = superSizeThatFits.width + padding.left + padding.right;
    CGFloat height = superSizeThatFits.height + padding.top + padding.bottom;
    return CGSizeMake(width, height);
}

@end

你需要计算UILabel大小，当你放置嵌入。它可以有不同的行数，因为文本对齐，换行模式。

override func drawText(in rect: CGRect) {

    let size = self.sizeThatFits(UIEdgeInsetsInsetRect(rect, insets).size);
    super.drawText(in: CGRect.init(origin: CGPoint.init(x: insets.left, y: insets.top), size: size));
}

override var intrinsicContentSize: CGSize {

    var size = super.intrinsicContentSize;

    if text == nil || text?.count == 0 {
        return size;
    }

    size = self.sizeThatFits(UIEdgeInsetsInsetRect(CGRect.init(origin: CGPoint.zero, size: size), insets).size);
    size.width  += self.insets.left + self.insets.right;
    size.height += self.insets.top + self.insets.bottom;

    return size;
}

尝试 iEun/InsetLabel

#import "E_LabelWithPadding.h"
#define padding UIEdgeInsetsMake(2, 0, 2, 0)
#define padding1 UIEdgeInsetsMake(0, 0, 0, 0)
@implementation E_LabelWithPadding
- (void)drawTextInRect:(CGRect)rect {
if (![self.text isEqualToString:@""]) {
    [super drawTextInRect:UIEdgeInsetsInsetRect(rect, padding)];
}else {
    [super drawTextInRect:UIEdgeInsetsInsetRect(rect, padding1)];
}

}

- (CGSize) intrinsicContentSize {
if (![self.text isEqualToString:@""]) {
    CGSize superContentSize = [super intrinsicContentSize];
    CGFloat width = superContentSize.width + padding.left + padding.right;
    CGFloat height = superContentSize.height + padding.top + padding.bottom;
    return CGSizeMake(width, height);
}else {
    CGSize superContentSize = [super intrinsicContentSize];
    CGFloat width = superContentSize.width + padding1.left + padding1.right;
    CGFloat height = superContentSize.height + padding1.top + padding1.bottom;
    return CGSizeMake(width, height);
}

}

- (CGSize) sizeThatFits:(CGSize)size {
if (![self.text isEqualToString:@""]) {
    CGSize superSizeThatFits = [super sizeThatFits:size];
    CGFloat width = superSizeThatFits.width + padding.left + padding.right;
    CGFloat height = superSizeThatFits.height + padding.top + padding.bottom;
    return CGSizeMake(width, height);
}else {
    CGSize superSizeThatFits = [super sizeThatFits:size];
    CGFloat width = superSizeThatFits.width + padding1.left + padding1.right;
    CGFloat height = superSizeThatFits.height + padding1.top + padding1.bottom;
    return CGSizeMake(width, height);
}

}

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。

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];
