ios4 - 如何更改单个按钮的检查图像？

Question

我实现了检查按钮图像的代码。现在我想在单击时更改该按钮中的图像，但每当我单击时，它只显示单个图像。这里我是这样实现的

-

(IBAction)name:(id)sender{

currenttagvalue = [sender tag];int count = 0;

switch (currenttagvalue) {
        case 1:

            if (count == 0)
{

 [level1 setImage:[UIImage imageNamed:@"one_time_selected.png"] 

forState:UIControlStateNormal];  

count++'

}

 if (count == 1)

{

 [level1 setImage:[UIImage imageNamed:@"two_time_selected.png"] 

forState:UIControlStateNormal];  

count++'

}

 if (count == 2)
{

 [level1 setImage:[UIImage imageNamed:@"one_time_selected.png"] 


forState:UIControlStateNormal];  

count++'

}

 if (count == 2)
{

 [level1 setImage:[UIImage imageNamed:@"three_time_selected.png"] 


forState:UIControlStateNormal];  

count++'

}

提前感谢您

count将值声明为static，例如：

static int count;
