通过导航呈现自定义尺寸的视图控制器 [英] Presenting a view controller of custom size with navigation

问题描述

我想提供一个自定义大小的视图控制器说（500,500）。我尝试用下面的代码做到这一点，如果我单独呈现视图控制器，但是当我将视图控制器放在导航控制器（我想做）时，它可以正常使用半透明浅灰色背景，有黑色背景出现了，我不想要这个，我想要灰色的。

我在这个问题的帮助下做了以下代码：

I want to present a view controller of custom size say (500,500). I try to do that with the below code, it works fine with a semi transparent light gray background if I present the view controller alone but when i put the view controller in a navigation controller (which I want to do) there is a black background that comes up, I dont want this and I want the gray one.

I did the following code with the help of this question:

iOS -- how do you control the size of a modal view controller?

MyViewController *vc=[[MyViewController alloc]initWithNibName:@"MyViewController" bundle:nil];

UINavigationController *nav=[[UINavigationController alloc]initWithRootViewController:vc];

nav.modalPresentationStyle=UIModalPresentationPageSheet;

[self.window.rootViewController presentModalViewController:nav animated:YES];

CGRect r = CGRectMake(self.window.rootViewController.view.bounds.size.width/2 - 250,
                              self.window.rootViewController.view.bounds.size.height/2 - 250,
                              500, 500);
r = [self.window.rootViewController.view convertRect:r toView:vc.view.superview.superview];
  vc.view.superview.superview.frame = r;

Any guess, what I am missing here?? Or is there a easy way to present a custom size VC with navigation??

With navigation:

Without navigation: (i am using a dark background, so it may appear like it is black but it is not)

解决方案

Just putting transparent overlay on the view controller and present it, sothat it looks like as what you actually want...
