Question

解决方案：将它们添加到uistackview中并希望并祈祷互联网上的代码最终看起来很好，在这种情况下确实如此。编辑;似乎间距并没有真正起作用，但是当添加另一个（不适当的间隔，如果我想出来会更新）

    if (self) {
        //CGFloat width = [UIScreen mainScreen].bounds.size.width;
     //CGPoint point = [self convertPoint:self.center fromView:self.superview];

        // button 1
        UIImage *bugImage = [[UIImage alloc] initWithContentsOfFile:[NSString stringWithFormat:@"%@/Bug.png", kSelfBundlePath]];
         //UIButton *bugbutton = [[UIButton alloc] initWithFrame:CGRectMake(point.x+(width/4),point.y, 70, 70)];
            UIButton *bugbutton = [[UIButton alloc] initWithFrame:CGRectMake(0, 0, 70, 70)];
    [bugbutton setImage:bugImage forState:UIControlStateNormal];
    [bugbutton addTarget:self action:@selector(bugButton) forControlEvents:UIControlEventTouchUpInside];
        [bugbutton.heightAnchor constraintEqualToConstant:100].active = true;
     [bugbutton.widthAnchor constraintEqualToConstant:100].active = true;
  //  [self addSubview:bugbutton];


        //button 2
        UIImage *paypalImage = [[UIImage alloc] initWithContentsOfFile:[NSString stringWithFormat:@"%@/Paypal.png", kSelfBundlePath]];
       //UIButton *paypalbutton = [[UIButton alloc] initWithFrame:CGRectMake(point.x+(width/8),point.y, 70, 70)];
            UIButton *paypalbutton = [[UIButton alloc] initWithFrame:CGRectMake(0, 0, 70, 70)];
    [paypalbutton setImage:paypalImage forState:UIControlStateNormal];
    [paypalbutton addTarget:self action:@selector(paypalButton) forControlEvents:UIControlEventTouchUpInside];

     [paypalbutton.heightAnchor constraintEqualToConstant:100].active = true;
    [paypalbutton.widthAnchor constraintEqualToConstant:100].active = true;
  //  [self addSubview:paypalbutton];

        //button 3
        UIImage *btcImage = [[UIImage alloc] initWithContentsOfFile:[NSString stringWithFormat:@"%@/bitcoin.png", kSelfBundlePath]];
      //UIButton *btcbutton = [[UIButton alloc] initWithFrame:CGRectMake(point.x+(width/16),point.y, 70, 70)];
        UIButton *btcbutton = [[UIButton alloc] initWithFrame:CGRectMake(0, 0, 70, 70)];
        [btcbutton setImage:btcImage forState:UIControlStateNormal];
        //[btcbutton setTitle:@"Send BTC" forState:UIControlStateNormal];
        //[btcbutton.titleLabel setTextAlignment: NSTextAlignmentCenter];
        [btcbutton addTarget:self action:@selector(btcButton) forControlEvents:UIControlEventTouchUpInside];
        [btcbutton.heightAnchor constraintEqualToConstant:100].active = true;
     [btcbutton.widthAnchor constraintEqualToConstant:100].active = true;
    //  [self addSubview:btcbutton];

        //Stack View
    UIStackView *stackView = [[UIStackView alloc] init];

    stackView.axis = UILayoutConstraintAxisHorizontal;
    stackView.distribution = UIStackViewDistributionEqualSpacing;
    stackView.alignment = UIStackViewAlignmentCenter;
    stackView.spacing = 60;

    [stackView addArrangedSubview:bugbutton];
     [stackView addArrangedSubview:paypalbutton];
     [stackView addArrangedSubview:btcbutton];

     stackView.translatesAutoresizingMaskIntoConstraints = false;
     [self addSubview:stackView];
    }

所以目前我有两个按钮出现在自定义按钮单元格中，除了它们重叠的事实外，它们的效果非常好。

我希望它们从中心均匀分布（如果我能以允许我添加/删除按钮而不破坏间距的方式实现它）。

找到一段看起来像我想要的代码，但我似乎无法使它工作，对编码很新，所以不确定是不是因为我写错了

button.center = [self convertPoint:self.center fromView:self.superview];

有关如何解决这个问题的任何建议？以下是我在下面的内容，感谢任何想法/帮助

 - (instancetype)initWithStyle:(UITableViewCellStyle)style reuseIdentifier:(id)reuseIdentifier specifier:(id)specifier {
self = [super initWithStyle:style reuseIdentifier:reuseIdentifier specifier:specifier];



    if (self) {

        // buttons
                UIImage *bugImage = [[UIImage alloc] initWithContentsOfFile:[NSString stringWithFormat:@"%@/Bug.png", kSelfBundlePath]];
    UIButton *bugbutton = [[UIButton alloc] initWithFrame:CGRectMake(0, 0, 70, 70)];
[bugbutton setImage:bugImage forState:UIControlStateNormal];
[bugbutton addTarget:self action:@selector(bugButton) forControlEvents:UIControlEventTouchUpInside];
[self addSubview:bugbutton];
    bugbutton.center = [self convertPoint:self.center fromView:self.superview];


    UIImage *paypalImage = [[UIImage alloc] initWithContentsOfFile:[NSString stringWithFormat:@"%@/Paypal.png", kSelfBundlePath]];
    UIButton *paypalbutton = [[UIButton alloc] initWithFrame:CGRectMake(0, 0, 70, 70)];
[paypalbutton setImage:paypalImage forState:UIControlStateNormal];
[paypalbutton addTarget:self action:@selector(paypalButton) forControlEvents:UIControlEventTouchUpInside];
[self addSubview:paypalbutton];
    paypalbutton.center = [self convertPoint:self.center fromView:self.superview];


    }

    return self;
     }

     - (instancetype)initWithSpecifier:(PSSpecifier *)specifier {
    return [self initWithStyle:UITableViewCellStyleDefault reuseIdentifier:@"harpButtonCell" specifier:specifier];
     }

Answer 1

您想要的图像是使用带有.equalSpacing分布的UIStackView轻松创建的排列。除了固定或以其他方式定位堆栈视图外，无需代码。

结果适用于不同的屏幕尺寸：

我认为你应该指定x位置;

- (instancetype)initWithStyle:(UITableViewCellStyle)style reuseIdentifier:(id)reuseIdentifier specifier:(id)specifier {
            self = [super initWithStyle:style reuseIdentifier:reuseIdentifier specifier:specifier];

if (self) {
     CGFloat width = [UIScreen mainScreen].bounds.size.width;
     CGPoint point = [self convertPoint:self.center fromView:self.superview];

     UIImage *bugImage = [[UIImage alloc] initWithContentsOfFile:[NSString stringWithFormat:@"%@/Bug.png", kSelfBundlePath]];
     UIButton *bugbutton = [[UIButton alloc] initWithFrame:CGRectMake(point.x+(width/4),point.y, 70, 70)];
     [bugbutton setImage:bugImage forState:UIControlStateNormal];
     [bugbutton addTarget:self action:@selector(bugButton) forControlEvents:UIControlEventTouchUpInside];
     [self addSubview:bugbutton];

     UIImage *paypalImage = [[UIImage alloc] initWithContentsOfFile:[NSString stringWithFormat:@"%@/Paypal.png", kSelfBundlePath]];
     UIButton *paypalbutton = [[UIButton alloc] initWithFrame:CGRectMake(frame.size.width-(width/4), point.y, 70, 70)];
     [paypalbutton setImage:paypalImage forState:UIControlStateNormal];
     [paypalbutton addTarget:self action:@selector(paypalButton) forControlEvents:UIControlEventTouchUpInside];
     [self addSubview:paypalbutton];
     }
return self;
}
