iOS - QLPreviewController - 如何阻止QuickLook旋转？

Question

我有QuickLook(QLPreviewController)几乎按照我想要的方式工作,但由于图像特征,我不希望它旋转成纵向.我在"shouldAutoRotateToInterfaceOrientation"方法中配置它只返回yes用于横向旋转(参见下面的代码详细信息)但它仍然旋转到肖像.

注意: shouldAutoRotateToInterfaceOrientation是一个直接副本,在我的所有视图控制器中用于此项目,它在其他视图控制器中工作.

//
//  documentViewer.m
//

#import "DocumentViewer.h"

@implementation DocumentViewer

@synthesize documents;

// Override to allow orientations other than the default portrait orientation.
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation {
    if (interfaceOrientation == UIInterfaceOrientationLandscapeLeft)
        return YES;
    else if (interfaceOrientation == UIInterfaceOrientationLandscapeRight)
        return YES;
    else 
        return NO;
}

- (void)viewDidLoad {
    [super viewDidLoad];

}

//-(void)viewWillAppear:(BOOL)animated {
//  
//  self.userInteractionEnabled = YES;
//}

//Nessary for Enabling User Interaction
- (BOOL)canBecomeFirstResponder {
    return YES;
}

-(void) createList:(NSString *) document {

    documents =     [[NSArray arrayWithObjects:document, nil] retain];
}

-(NSInteger) numberOfPreviewItemsInPreviewController: (QLPreviewController *) controller {

    return [documents count];
}

- (id <QLPreviewItem>) previewController: (QLPreviewController *) controller previewItemAtIndex: (NSInteger) index {

    return [NSURL fileURLWithPath:[[NSBundle mainBundle] pathForResource:[documents objectAtIndex:index] ofType:nil]];
}
@end

Answer 1

在AppDelegate.m中替换

返回UIInterfaceOrientationMaskAll;

同

返回UIInterfaceOrientationMaskLandscape;

像这样:

- (NSUInteger)application:(UIApplication *)application supportedInterfaceOrientationsForWindow:(UIWindow *)window{
    return UIInterfaceOrientationMaskLandscape;
}

Answer 2

我从来没有找到一个好的答案，所以我最终只使用了 UIWebView。

但我仍在寻找。
