iphone - 通过编程 View 创建避免对 iPhone 屏幕尺寸进行硬编码

Question

我正在查找如何以编程方式创建 View ，并找到了以下示例代码:

self.view = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 320, 480)];

这很好用，但我不喜欢它硬编码屏幕的大小。有没有办法查看屏幕尺寸？有人提出的一个重要观点是，如果应用程序在通话过程中运行，那么屏幕会因为绿色的“返回通话”栏而稍微小一些。

Answer 1

Is there a way to look up the size of the screen?

是的:

CGRect screenRect = [[UIScreen mainScreen] applicationFrame];

applicationFrame

This property contains the screen bounds minus the area occupied by the status bar, if it is visible. Using this property is the recommended way to retrieve your application’s initial window size. The rectangle is specified in points.
