iOS 纵向和横向应用仅适用于 iPhone 6+/7+

Question

如何设置我的项目配置以允许我的应用在 iPhone 6+ 和 7+ 型号上同时以纵向和横向模式工作，而其他 iPhone 型号必须仅支持纵向？

Answer 1

use this third party lib for detecting the running device's model and screen size.

//AppDelegate.h

@property () BOOL restrictRotation;

//AppDelegate.m

导入“AppDelegate.h”

导入“SDVersion.h”

@implementation AppDelegate

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{

 // Check for device model
if ([SDiOSVersion deviceVersion] == iPhone7Plus){
    NSLog(@"You got the iPhone 7. Nice!");
  restrictRotation=YES;
}
else if ([SDiOSVersion deviceVersion] == iPhone6SPlus){
    NSLog(@"You got the iPhone 6S Plus. Awesome device!");
   restrictRotation=YES;
}


 return YES;
}

-(UIInterfaceOrientationMask )application:(UIApplication *)application supportedInterfaceOrientationsForWindow:(UIWindow *)window
{
    if(self.restrictRotation)
    {
        return UIInterfaceOrientationMaskPortrait;
    }
    else
    {
       return UIInterfaceOrientationMaskAll;
    }
    
}
