Question

我正在开发我的应用程序以兼容iphone 5.在下面的代码中，donebutton适用于iphone 4，但是当涉及到iphone5时，它是不可触摸的！我不知道为什么？

 float screenSizeHeight=[UIScreen mainScreen].bounds.size.height;


if(screenSizeHeight==568)
{
    UIImageView *my_image_view = [[UIImageView alloc] initWithImage:[UIImage imageNamed:@"Plain_Background2.png"]];
    [my_image_view setFrame:CGRectMake(0,20,320,568)];
    [self.view addSubview:my_image_view];
    [self.view sendSubviewToBack:my_image_view];

    imageScrollView = [[UIScrollView alloc] initWithFrame:CGRectMake(0, 20, 320, 460)];
    [doneButtonOutlet setFrame:CGRectMake(124,470,72,28)];
}
if(screenSizeHeight==480)
{
    UIImageView *my_image_view = [[UIImageView alloc] initWithImage:[UIImage imageNamed:@"Plain_Background.png"]];
    [my_image_view setFrame:CGRectMake(0,20,320,480)];
    [self.view addSubview:my_image_view];
    [self.view sendSubviewToBack:my_image_view];
    imageScrollView = [[UIScrollView alloc] initWithFrame:CGRectMake(0, 20, 320, 400)];
    [doneButtonOutlet setFrame:CGRectMake(124,432,72,28)];
}

Answer 1

这是因为在iPhone 5中，scrollView的高度更高，它位于按钮上方。

因此改变UIButton的起源y。

    imageScrollView = [[UIScrollView alloc] initWithFrame:CGRectMake(0, 20, 320, 460)]; 
// Here imageScrollView bottom is at 480 pixel and doneButtonOutlet origin is at 470 so either small height of scrollview or change button origin y.. 
        [doneButtonOutlet setFrame:CGRectMake(124,470,72,28)];

希望它对你有所帮助。
