我正在使用以下代码添加一系列带有Array的UIButtons。我想知道是否有办法在每个按钮之间添加一些间距,因为它们目前距离太近。

这是我的代码,感谢您的帮助:

 // Create buttons for the sliding category menu.
    buttonArray = [NSMutableArray array];
    myImages = [NSArray arrayWithObjects:@"category-cafe-unsel.png", @"category-food-unsel.png", @"category-clothing-unsel.png", @"category-health-unsel.png", @"category-tech-unsel_phone.png" , @"category-tech2-unsel.png", @"catefory-theatre-unsel.png", @"category-travel-unsel.png", nil];

    myImagesSel = [NSArray arrayWithObjects:@"category-cafe-sel.png", @"category-food-sel.png", @"category-clothing-sel.png", @"category-health-sel.png", @"category-tech-sel_phone.png" , @"category-tech2-sel.png", @"catefory-theatre-sel.png", @"category-travel-sel.png", nil];

    // only create the amount of buttons based on the image array count
    for(int i = 0;i < [myImages count]; i++)
    {
        // Custom UIButton

        btn.tag  = i+1;

        btn = [UIButton buttonWithType:UIButtonTypeCustom];

        [btn setFrame:CGRectMake(0.0f, 20.0f, 52.0f, 52.0f)];
        [btn setTitle:[NSString stringWithFormat:@"Button %d", i] forState:UIControlStateNormal];
        [btn setImage:[UIImage imageNamed:[myImages objectAtIndex:i]] forState:UIControlStateNormal];
        [btn setImage:[UIImage imageNamed:[myImagesSel objectAtIndex:i]] forState:UIControlStateSelected];

        NSLog(@"The button title is %@ ", btn.titleLabel.text);

        [btn addTarget:self action:@selector(buttonPressed:) forControlEvents:UIControlEventTouchUpInside];
        [buttonArray addObject:btn];


     //   NSLog(@"Button tag is: %d",btn.tag);

    }

    UIImageView *blackColor = [[UIImageView alloc] initWithImage:[UIImage imageNamed:@"blackColor.png"]];


    // initialize the slide menu by passing a suitable frame, background color and an array of buttons.
    slideMenuView = [[SlideMenuView alloc] initWithFrameColorAndButtons:CGRectMake(0.0f, 0.0f, 320.0f, 80.0f) backgroundColor:[UIColor clearColor]  buttons:buttonArray];

试试这个:[btn setFrame:CGRectMake(0.0f, i*25.0f, 52.0f, 52.0f)];按钮之间会有5个像素差距

使用:

垂直间距:

 [btn setFrame:CGRectMake(0.0f, (20.0f + ((52.0 * i) +5)), 52.0f, 52.0f)];

水平间距

if(i==0)
{
   [btn setFrame:CGRectMake(0.0, 52.0, 52.0f, 52.0f)];
}
else
{
   [btn setFrame:CGRectMake((52.0+(52.0 * i)+5), 52.0, 52.0f, 52.0f)];
}

答案 2 :(得分:0)

试试这个: -

[btn setFrame:CGRectMake(0.0f + 54 * i,20.0f,52.0f,52.0f)];
