iphone - 如何在 uibutton 中分配两次标题

Question

在我的应用程序中，我有 10 个 UIButton 和一个包含 5 个文本值的数组。我想为 10 个按钮分配每个值两次。？这里是我的代码

NSString *name;
int value = rand() % ([texts 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.tag == 5||button.tag == 6||button.tag == 7||button.tag == 8||button.tag == 9||button.tag == 10||button.tag == 11||button.tag == 12||button.tag == 13||button.tag == 14||button.tag == 15||button.tag == 16||button.tag == 17||button.tag == 18||button.tag == 19||button.tag == 20)
        {
             name=[NSString stringWithFormat:@"%@",[texts objectAtIndex:value]];
            [button setTitle:name forState:UIControlStateNormal];
            NSLog(@"current  name :%@",name);
        }
    }
   }  

但它显示了所有具有标题的按钮。请帮我将两个按钮更改为仅标题

Answer 1

实现此目的的一个棘手方法是标记 UIButtons，如果您希望button1和button2标题相同，请提供button1.tag = 1和button2.tag = 100 即 button2.tag = button1.tag * 100(不要以 0 作为标签开头，因为 0 是 self.view 的保留标签)。这可以通过 XIB 或以编程方式完成。进一步执行以下内容

for (int i = 0 ;i < [array count] ; i++) {
int myTag = i + 1;

UIButton *button1 = [self.view viewWithTag:myTag];
    [button1 setTitle:[array objectAtIndex:i] forState:UIControlStateNormal];

UIButton *button2 = [self.view viewWithTag:myTag * 100];
    [button2 setTitle:[array objectAtIndex:i] forState:UIControlStateNormal];

 }
