iphone - 每次点击更改4个按钮标题

我的应用程序中有四个按钮，我从数组中获取按钮标题，我想每当我单击任何按钮时都更改4个按钮标题，但是这里被单击的按钮标题只是改变了，这是我的代码，

-(IBAction)setting:(id)sender
{
int value = rand() % ([arraytext count] -1) ;
UIButton *mybuton = (UIButton *)sender;
[mybuton setTitle:[arraytext objectAtIndex:value] forState:UIControlStateNormal];
}

更新

-(IBAction)answersetting:(id)sender
{

UIButton *mybutton = (UIButton *)sender;
static int j = 0;
if(sender == mybutton)
    j++;
if (j >= arcount)
{
    j = 0;
}
else if(j < 0)
{
    j = arcount - 1;
}

CATransition *transition = [CATransition animation];
transition.duration = 1.0f;
transition.timingFunction = [CAMediaTimingFunction    functionWithName:kCAMediaTimingFunctionEaseOut];
transition.type = kCATruncationMiddle;

[animage.layer addAnimation:transition forKey:nil];
animage.image=[arimage objectAtIndex:j];

for(UIView *view in self.view.subviews)
{
    if([view isKindOfClass:[UIButton class]])
    {
        UIButton *button = (UIButton *)view;
        if(button.tag == 1||button.tag == 2||button.tag == 3||button.tag == 4)
        {
            int value = rand() % ([artext count] -1) ;
            NSMutableDictionary *dictionary = [[NSMutableDictionary alloc]init];
            [dictionary setValue:animage.image forKey:@"button"];
            [button setTitle:[artext objectAtIndex:value] forState:UIControlStateNormal];

        }
    }
}

}

我将此方法与4个按钮相关联，我想在单击任何按钮时更改所有按钮标题，请帮助进行编码

最佳答案

因为sender仅保留您单击的那个UIButton。
要更改所有UIButton的标题，您需要循环。
将tag设置为全部4个buttons。

然后这样做-

-(IBAction)setting:(id)sender
{
     int value = rand() % ([arraytext count] -1) ;
     for(UIView *view in self.view.subviews)
     {
        if([view isKindOfClass:[UIButton class]])
        {
            UIButton *button = (UIButton *)view;
            if(button.tag == 1||button.tag == 2||button.tag == 3||button.tag == 4)
            {
                [button setTitle:[arraytext objectAtIndex:value] forState:UIControlStateNormal];
            }
        }
     }
}
