Ios5 dismissViewControllerAnimated:完成：不适用于iPhone 5

因此，在我的iPhone4设备中，在我选择图像后，我希望图像选择器弹出框消失。以下代码适用于iOS 5上的iPad3、iOS 6上的iPad4、iOS 5上的iPhone4，但以下代码不适用于iOS 6上的iPhone5。为什么会这样

- (void) imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info {
[self loadImage:[info objectForKey:UIImagePickerControllerOriginalImage]];

if (UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPad ) {
    if ([popoverController isPopoverVisible]) {
        // called for iPad
        [popoverController dismissPopoverAnimated:YES];
    }
}
else {
    // called for iPhone
    [self dismissModalViewControllerAnimated:YES]; <== NOT WORKING
    [self dismissViewControllerAnimated:YES completion:nil]; <== ALSO NOT WORKING
}

-（void）imagePickerController:（UIImagePickerController*）选取器未使用信息完成PickingMediaWithInfo:（NSDictionary*）信息{
[self-loadImage:[info-objectForKey:UIImagePickerController原始图像]；
if（UI\u USER\u INTERFACE\u IDIOM（）==UIUserInterfaceIdiomPad）{
如果（[popoverController ispoverVisible]）{
//要求购买iPad
[popoverController解除PopOveranimated:是]；
}
}
否则{
//呼吁iPhone
[self dismissModalViewControllerAnimated:YES]；看起来您是在告诉图像选取器（self）的代理，而不是图像选取器本身
