的UIButton沒有可觸 - 自定義從iPhone 4到iPhone 5

Question

我的工作我的應用程序做出iphone 5在下面的代碼，爲iPhone 4 donebutton工程兼容，但是當涉及到的iPhone5是不是可觸摸！我不知道爲什麼？

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

這是因爲在iPhone 5中，scrollView的高度更高，它位於按鈕上方。

所以改變UIButton的原點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)]; 

希望它可以幫助你。
