Question

我必须为多个按钮设置边框并调整插图，所以我为UIButton写了一个类别类来添加边框并调整边缘插图。

这是我的ui button catgory代码

@implementation UIButton (BorderAndEdgeInsets)

- (void) addBorderOnSides:(UITableViewcellSides )sides
               withColour:(UIColor *)colour
                  ofWidth:(float)width{

    CALayer *border = [CALayer layer];
    border.backgroundColor = [colour CGColor];
    if(sides & Top)
    {
        border.frame = CGRectMake(self.frame.origin.x, self.frame.origin.y, self.frame.size.width, width);
        [self.layer addSublayer:border];
    }

    if(sides & Right)
    {
        border.frame = CGRectMake(self.frame.size.width - width, self.frame.origin.y, width, self.frame.size.height);
        [self.layer addSublayer:border];
    }
    if(sides & Bottom)
    {
        border.frame = CGRectMake(self.frame.origin.x, self.frame.size.height - width, self.frame.size.width, width);
        [self.layer addSublayer:border];
    }
    if(sides & Left)
    {
        border.frame = CGRectMake(self.frame.origin.x, self.frame.origin.y, width, self.frame.size.height);
        [self.layer addSublayer:border];
    }
}

- (void) adjustImageAndTitleSpacings{
    [[self titleLabel] setTextAlignment:NSTextAlignmentCenter];
    [self setImageEdgeInsets:UIEdgeInsetsMake(0, 50, 20, 0)];
    [self setTitleEdgeInsets:UIEdgeInsetsMake(25, -15, 0, 0)];
}

这是我对按钮的用法：

int leftboundary = 0;
    for (NSDictionary *tab in tabDetails) {
        UIButton *tabButton = [[UIButton alloc]initWithFrame:CGRectMake(leftboundary, 0, 130, 66)];
        leftboundary += 130;
        [[tabButton titleLabel] setFont:[UIFont fontWithName:@"Helvetica" size:12]];
        [tabButton addBorderOnSides:Right withColour:[UIColor darkGrayColor] ofWidth:2];
        [tabButton addBorderOnSides:Top withColour:[UIColor whiteColor] ofWidth:5];
        [tabButton adjustImageAndTitleSpacings];

但在我的输出中，顶部白色边框仅在备用按钮上，而右边框在所有按钮上都是一致的。

我在这里做错了什么？提前谢谢。
