iOS - 支持iPad和iPad iPhone没有使用笔尖 [英] iOS - Support iPad & iPhone without using nib

问题描述

我正在尝试编写应用而不使用 nib ，我会以编程方式执行此操作。

I'm trying to write an app without using nib, everything I'll do it programmatically.

现在的问题是，我如何支持 iPad 和 iPhone ？显然，我不能用

Now the problem is, how am I going to support both iPad and iPhone? Obviously, I can't do it with

if ([[UIDevice currentDevice] userInterfaceIdiom] == UIUserInterfaceIdiomPad) {
    // load iPad nib
} else {
    // load iPhone nib
}

如果我创建2 ViewControllers ，那么 IBAction 将是多余的。

If I create 2 ViewControllers, then the IBAction will be redundant.

有什么建议吗？

推荐答案

您应该只是在 applicationDidFinishLaunching <中找出设备类型/ code>然后为每个设备加载单独的控制器。但是如果你想为所有设备只有一个实现，那么做这样的检查：

You should probably just figure out the device type in applicationDidFinishLaunching and then load separate controllers for each device. But if you want to just have a single implementation for all devices, do checks like this:

 if(UI_USER_INTERFACE_IDIOM()==UIUserInterfaceIdiomPad)
{
    //do some iPad stuff
}
else
{
    CGFloat screenH = [UIScreen mainScreen].bounds.size.height;

    if([UIScreen mainScreen].scale == 2.f && screenH == 568.0f)
    {
        //do iPhone 5 stuff
    }
    else
    {
        //do iPhone 4S and iPhone 4 stuff

        //the dimensions are the same however, if you want to do iPhone 4S specific stuff
        // you'll need to do additional checks against video resolution or other differences etc
    }
}
