目標c：代碼爲lanscaperight和landscapeleft

Question

我正在創建一個iPad，我想只有兩個方向：lanscape右和左（不是人像）......我已經改變了。 plist文件，但我應該寫在代碼中？

- (BOOL) shouldAutorotateToInterfaceOrientation: (UIInterfaceOrientation) {interfaceOrientation return?? }

Answer 1

試試這個方法：

- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation 
{ 
    return interfaceOrientation == UIInterfaceOrientationLandscapeLeft || interfaceOrientation == UIInterfaceOrientationLandscapeRight; 
} 

Answer 2

- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation { 
    return (interfaceOrientation == UIInterfaceOrientationLandscapeRight || interfaceOrientation == UIInterfaceOrientationLandscapeLeft); 
} 

還有，如果你想保持一點清潔劑就可以利用方便的功能：

return UIInterfaceOrientationIsLandscape(interfaceOrientation);
