ios - 水平均匀分布三个按钮ios

Question

我有三个UIButtons和一个支架UIView我想要我的三个 UIButton在 UIView 内垂直居中并且我希望它们在水平方向上均匀分布

float ycentre = CGRectGetMidY(self.buttonHolderView.bounds);
float xposition = (self.buttonHolderView.frame.size.width - 135.0f)/4.0f;


self.button1 = [[UIButton alloc]initWithFrame:CGRectMake(xposition,0, 45, 30)];
self.button1.center = CGPointMake(self.button1.frame.origin.x, ycentre);


self.button2 = [[UIButton alloc]initWithFrame:CGRectMake((xposition*2)+45,0, 45, 30)];
self.button2.center = CGPointMake(self.button2.frame.origin.x, ycentre);

self.button3 = [[UIButton alloc]initWithFrame:CGRectMake((xposition*3)+90,0, 45, 30)];
self.button3.center = CGPointMake(self.button3.frame.origin.x, ycentre);
[self.button3 addTarget:self action:@selector(ShareButtonClicked) forControlEvents:UIControlEventTouchUpInside];

[self.buttonHolderView addSubview:self.button1];
[self.buttonHolderView addSubview:self.button2];
[self.buttonHolderView addSubview:self.button3];

每个按钮的高度为 30 和宽度为 45，但我的代码没有平均分配它们，这是怎么回事？

将它们放在 UIStackView 中。它使 View 之间的间隔非常容易。
