Iphone：获取当前视图尺寸或屏幕尺寸 [英] Iphone: Get current view dimensions or screen dimensions

问题描述

您好我想获得主视图的宽度和高度。我想在横向或纵向模式下使用正确的值。我尝试了以下内容：

Hello i want to get the width and height of my main view. I want the correct value in landscape or portrait mode. I've tried the following:

  NSLog(@"aaa %f", [UIScreen mainScreen].applicationFrame.size.width);
  NSLog(@"zzz %f", self.view.frame.size.width);

这些在横向模式下为300，在纵向模式下为320，是的在纵向模式下更大。所以..我的视图占据整个屏幕（ - 状态栏）所以我希望在横向模式下为480，在纵向模式下为320。其余的像素发生了什么。我是否需要对这些值进行硬编码？谢谢。

These give 300 in landscape and 320 in portrait mode, yes it is larger in portrait mode. So.. my view takes up the whole screen (- status bar) so I expect 480 in landscape mode and 320 in portrait mode. What happened to the rest of the pixels. Do I have to hardcode these values? Thanks.

推荐答案

以下任一行是否适合您？

Do either of the following lines work for you?

[[UIScreen mainScreen] bounds].size.height
[[UIScreen mainScreen] bounds].size.width

我想你可以减去状态栏的高度？也许我不理解你的问题

I suppose you can subtract the height of the status bar? Maybe i'm not understanding your question
