Xcode 4.5背景图片iPhone 4,4s，5 [英] Xcode 4.5 background image iPhone 4, 4s, 5
问题描述
我在viewController.m中写了背景代码：
I have in my viewController.m written the background code:
self.view.backgroundColor = [UIColor colorWithPatternImage:[UIImage imageNamed:@"image.png"]];
我有不同图片的正确名称：
And I have the correct names of the different pictures:
image.png for non-retina display (320x480)
image@2x.png for retina display (640x960)
image-568h@2x.png for iPhone 5 (640x1136)
但是当我运行它时对于iPhone 5屏幕它没有采取image-568h@2x.png的模拟器它只需要图像@ 2x用于4s屏幕并缩放它以适应屏幕...我不知道是否有任何编码使用图像-568h @ 2x for iPhone 5 screen？
But when I run it in the simulator it does not take the image-568h@2x.png for iPhone 5 screen it only takes the image@2x for 4s screen and scale it to fit the screen... I dont know if there is any coding to use the image-568h@2x for iPhone 5 screen?
我正在使用Xcode 4.5
Im using Xcode 4.5
推荐答案
iPhone 5是视网膜，就像iPhone 4和4S一样，@ 2x图像将自动用于所有这些设备。对于iPhone 5，它只是一个名为-568h @ 2x的启动图像。你需要编写一些代码来使用不同的图像，这样的东西可以工作：
iPhone 5 is retina, just like iPhone 4 and 4S, and the @2x-image will be used automatically for all these devices. It's only the startup-image that is called "-568h@2x" for iPhone 5. You need to write some code to use a different image, something like this would work:
NSString *filename = @"image.png";
CGRect screenRect = [[UIScreen mainScreen] bounds];
if (screenRect.size.height == 568.0f)
filename = [filename stringByReplacingOccurrencesOfString:@".png" withString:@"-568h.png"];
imageView.image = [UIImage imageNamed:filename];这篇关于Xcode 4.5背景图片iPhone 4,4s，5的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持IT屋！
