iPhone 6和iPhone 6 Plus上的UIImageView高度缩放显示模式 [英] UIImageView height on iPhone 6 and iPhone 6 Plus Zoomed display mode

问题描述

我的ViewController中有一个UIImageView *backgroundImageView，并在我的viewDidLoad中调用了

I have a UIImageView *backgroundImageView in my ViewController and call in my viewDidLoad

[self.backgroundImageView sizeToFit]

我发现在 iPhone 6 上，高度从667 (Normal display)更改为558 (Zoomed display)

I found that on the iPhone 6 the height changes from 667 (Normal display) to 558 (Zoomed display)

但是在 iPhone 6 Plus 上，两者的高度均保持在736.

However on the iPhone 6 Plus the height remains the same at 736 for both.

这是预期的吗?

推荐答案

尝试一下.这里给出了基于您当前屏幕高度的代码.

Try it. Here Given code based on your current screen height.

float img = frame.size.height / frame.size.width;

frame.size.width = [[UIScreen mainScreen] bounds].size.width;

frame.size.height = frame.size.width * img ;
