如何在iOS Swift 3.1 Xcode 8.3.2中适用于iPad应用程序的iPhone应用程序

Question

我使用 swift 3 和 Xcode 8.3.2 制作 iOS应用，并且它正常工作（适合所有​​iPhone屏幕大小）但在 iPad 中有适合的问题 我在常规/目标设置中设置 iPhone 模式 我已经完成了这个过程，没有问题 请帮我修理它。我不想设置环球 看到这个：

Answer 1

您可以从info.plist为iPad和iPhone设置不同的故事板，也可以从appdelegate加载特定的故事板。你可以查看this link out

Answer 2

那么您可以通过在班级中使用以下代码来更改屏幕尺寸或组件约束值，从而可以为iphone和ipad设置视图。

@ControllerAdvice
public class PutMyEntityBodyAdvice implements ResponseBodyAdvice<Object> {

    @Override
    public boolean supports(MethodParameter returnType, Class<? extends HttpMessageConverter<?>> converterType) {

        // Write the condition to check if beforyBodyWrite should be called
        return returnType.getParameterType().equals(ResponseEntity.class);
    }

    @Override
    public Object beforeBodyWrite(Object object, MethodParameter returnType, MediaType selectedContentType,
                                  Class<? extends HttpMessageConverter<?>> selectedConverterType,
                                  ServerHttpRequest request, ServerHttpResponse response) {

        // Check if it is a PUT request for MyEntity object
        if (HttpMethod.PUT.equals(request.getMethod()) && object instanceof PersistentEntityResource) {
            PersistentEntityResource persistentEntityResource = (PersistentEntityResource) object;
            if (persistentEntityResource.getContent().getClass().equals(MyEntity.class)) {
                // Add custom header or manipulate response object
                response.getHeaders().add("X-Save", "MyEntity");
            }
        }
        return object;
    }
}

现在您可以像这样设置约束：==

    struct Device {
    // iDevice detection code
    static let IS_IPAD             = UIDevice.current.userInterfaceIdiom == .pad
    static let IS_IPHONE           = UIDevice.current.userInterfaceIdiom == .phone
    static let IS_RETINA           = UIScreen.main.scale >= 2.0
    static let SCREEN_WIDTH        = Int(UIScreen.main.bounds.size.width)
    static let SCREEN_HEIGHT       = Int(UIScreen.main.bounds.size.height)
    static let SCREEN_MAX_LENGTH   = Int( max(SCREEN_WIDTH, SCREEN_HEIGHT) )
    static let SCREEN_MIN_LENGTH   = Int( min(SCREEN_WIDTH, SCREEN_HEIGHT) )
    static let IS_IPHONE_4_OR_LESS = IS_IPHONE && SCREEN_MAX_LENGTH  < 568
    static let IS_IPHONE_5         = IS_IPHONE && SCREEN_MAX_LENGTH == 568
    static let IS_IPHONE_6         = IS_IPHONE && SCREEN_MAX_LENGTH == 667
    static let IS_IPHONE_6P        = IS_IPHONE && SCREEN_MAX_LENGTH == 736
    static let IS_IPHONE_X         = IS_IPHONE && SCREEN_MAX_LENGTH == 812
    }
