Ios 水平均匀分布三个按钮

我有三个

ui按钮

和一个支架

ui视图

我希望我的三个

ui按钮

在

ui视图

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，宽度为45，但“我的代码”并没有将它们平均分布。有什么问题吗？

请将它们放置在

UIStackView

中。它使视图之间的间隔变得非常均匀。

按如下所示设置按钮的

框

，不要设置

中心

float thirdOfWidth = (self.buttonHolderView.frame.width/3.0);
float buttonWidth = 45.0;
float buttonHeight = 30.0;

self.button1 = [[UIButton alloc]initWithFrame:CGRectMake(thirdOfWidth*0 + (thirdOfWidth - buttonWidth)/2, (self.buttonHolderView.frame.height - buttonHeight)/2, 45, 30)];

self.button2 = [[UIButton alloc]initWithFrame:CGRectMake(thirdOfWidth*1 + (thirdOfWidth - buttonWidth)/2, (self.buttonHolderView.frame.height - buttonHeight)/2, 45, 30)];

self.button3 = [[UIButton alloc]initWithFrame:CGRectMake(thirdOfWidth*2 + (thirdOfWidth - buttonWidth)/2, (self.buttonHolderView.frame.height - buttonHeight)/2, 45, 30)];

它也可以通过任意数量的按钮在循环中完成

        NSInteger count = 3;
        CGFloat buttonWidth = 45;
        CGFloat buttonHeight = 30;
        CGFloat x = (self.bounds.size.width - buttonWidth) / 2;
        CGFloat verticalSpacing = ((self.bounds.size.height - buttonHeight * count) / count) - buttonHeight / 2;
        CGFloat y = verticalSpacing;

        for (int i = 0; i < count; i++) {
            UIButton *button = [[UIButton alloc] initWithFrame:CGRectMake(x, y, buttonWidth, buttonHeight)];
            [self addSubview:button];
            y += buttonHeight + verticalSpacing;
        }

NSInteger计数=3；
CGFloat按钮宽度=45；
CGFloat按钮高度=30；
CGFloat x=（self.bounds.size.width-buttonWidth）/2；
CGFloat垂直间距=（（self.bounds.size.height-buttonHeight*count）/count）-buttonHeight/2；
cGy=垂直间距；
for（int i=0；i
