ios5 - 模型視圖控制器的大小與故事板

Question

1. 是否有任何方式來調整已使用故事板segue模態呈現的視圖控制器的大小？

2. 如何通過翻轉過渡從此模態視圖控制器中呈現另一個視圖控制器？

如果我將其定義爲Style = Modal，Presentation = Default，Transition = Flip Horizo​​ntal，它看起來很奇怪（背景是白色的）。

Thx！

Answer 1

是的。在界面構建器中選擇視圖控制器，並在屬性檢查器中設置Size以自由形式（從推斷）。然後選擇視圖並將其測量值設置爲您需要的值。一個重要的注意點是在視圖控制器中取消選中從NIB調整視圖大小，否則視圖將再次變爲全屏。

不確定第二個問題，如果背景是唯一的問題，你不能只是設置顏色？

希望這會有所幫助。

Answer 2

我試圖做同樣的，在故事板我ModalView較小，但在模擬器它涵蓋了所有的屏幕...

我覺得這不能在iPhone上完成了...（我在iPad上做了一個簡單的測試，模態視圖起作用）。

我會嘗試iPhone的半透明視圖，不會使用模態視圖。

希望這會有所幫助。

您可以使用自定義UIStoryboardSegue調整模態顯示視圖的大小。在故事板中，將segue設置爲Custom而不是Modal。在Segue類中，給它一個你的UIStoryboardSegue覆蓋的名字。

要覆蓋UIStoryboardSegue，您在.h文件中不需要任何東西。它會出現這樣的事情：

MyStoryboardSegue.h：

#import <UIKit/UIKit.h> 
@interface MyStoryboardSegue : UIStoryboardSegue 
@end 

在MyStoryboardSegue.m，代碼爲：

#import "MyStoryboardSegue.h" 

@implementation MyStoryboardSegue 


- (void)perform 
{ 
    id sourceController = self.sourceViewController; 
    id destinationController = self.destinationViewController; 
    UIView *destinationView = [destinationController view]; 
    CGFloat x, y, w, h; 

    [destinationController setModalPresentationStyle:UIModalPresentationFormSheet]; 
    [destinationController setModalTransitionStyle:UIModalTransitionStyleCrossDissolve]; 
    [sourceController presentViewController:destinationController animated:YES completion:nil]; 

/* 
You have to present the view first, and then resize it. That's because, 
as far as I can tell, when you present your view modally, a new view is created 
that covers the screen in a black semi-transparent mask to give the shadow effect, 
and a container view is placed in the middle of this view that in turn holds the 
view you are presenting. Your view automatically resizes to the size of this 
container view, so that's the view you need to resize to make your view controller 
appear the size you desire. You must present your modal view first 
because until you do, the container view doesn't exist. The following code 
resizes the container view (which is now your modal view's superview) and then 
resets the position of the container view to the center of the source view that 
is presenting the modal view so everything looks nice and centered. 
*/ 
    x = destinationView.superview.frame.origin.x; 
    y = destinationView.superview.frame.origin.y; 
    w = 400; // Your desired modal view width 
    h = 400; // Your desired modal view height 
    destinationView.superview.frame = CGRectMake(x, y, w, h); 
    destinationView.superview.center = [[sourceController view] center]; 
}
