我们可以为 iPad 而不是 iPhone 显示 Settings.bundle 设置吗？

Question

Suppose I want to give permission to the user if he wants to rotate in iPad. There is no rotation scheme for iPhone so I need not provide this option of iPhone settings.

Answer 1

To check if the device is iPad, you can do this:

if ([UIDevice currentDevice].userInterfaceIdiom == UIUserInterfaceIdiomPad) {
    //Setting for iPad
}
else {
    //Setting for iPhone
}

Similarly you can also do this:

if ([UIDevice currentDevice].userInterfaceIdiom == UIUserInterfaceIdiomPhone) {
    //Setting for iPhone
}
else {
    //Setting for iPad
}

Answer 2

BOOL isiPad;
//Declare global Bool value
if (UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPad) {
// The device is an iPad 
// Enable rotation here
 isiPad=YES;
}
else {
// The device is an iPhone or iPod touch.
// disable rotation here
}


//Set your rotation methods here 
-(BOOL)shouldAutorotate
{

        return isiPad;
}

In your project

Target->Summery-> Supported Interface Orientations in that it gives settings for interface orientations for iPhone and i pad separately Check it once

Like below image

Answer 4

Settings.bundle file is common in program. Its not like that if you an Universal application than you can have separate file for both iPhone & iPad. It will be 1 common file.

You should give validations by checking If iPad Device than you can open orientations or if iPhone Device & lock the Orientation.
