我正在使用documenthandler cordova插件,在该插件中,如果单击该按钮,则可以从正常工作的url中获取文档处理程序中的pdf,这样我就可以将pdf保存到iBooks中。
现在,与其在查看器中打开文档并单击“共享”按钮,然后再次单击以保存到iBook中,我需要能够在不打开文档的情况下触发共享按钮。我知道可以使用presentOpenInMenuFromRect
而不是presentViewController
来完成此操作,但是由于某些原因,它无法正常工作,代码如下:
#import "DocumentHandler.h"
@implementation DocumentHandler
- (void)HandleDocumentWithURL:(CDVInvokedUrlCommand*)command;
{
CDVPluginResult *commandResult = [CDVPluginResult resultWithStatus:CDVCommandStatus_OK messageAsString:@""];
__weak DocumentHandler* weakSelf = self;
dispatch_queue_t asyncQueue = dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_DEFAULT, 0);
dispatch_async(asyncQueue, ^{
NSDictionary* dict = [command.arguments objectAtIndex:0];
NSString* urlStr = dict[@"url"];
NSURL* url = [NSURL URLWithString:urlStr];
NSData* dat = [NSData dataWithContentsOfURL:url];
NSString* fileName = [url lastPathComponent];
NSString* path = [NSTemporaryDirectory() stringByAppendingPathComponent: fileName];
NSURL* tmpFileUrl = [[NSURL alloc] initFileURLWithPath:path];
[dat writeToURL:tmpFileUrl atomically:YES];
weakSelf.fileUrl = tmpFileUrl;
dispatch_async(dispatch_get_main_queue(), ^{
QLPreviewController* cntr = [[QLPreviewController alloc] init];
cntr.delegate = weakSelf;
cntr.dataSource = weakSelf;
UIViewController* root = [[[UIApplication sharedApplication] keyWindow] rootViewController];
[root presentViewController:cntr animated:YES completion:nil];//this works fine and open the document with share button
CGRect rect = CGRectMake(0, 0, 1024, 768);
[root presentOpenInMenuFromRect:rect inView:self.view animated:YES]; // this doesn't work where
//I want to see only sharing options
//here are errors,one of them is /Property'view' not found on object of type ''DocumentHandler
});
[weakSelf.commandDelegate sendPluginResult:commandResult callbackId:command.callbackId];
});
}
#pragma mark - QLPreviewController data source
- (NSInteger) numberOfPreviewItemsInPreviewController: (QLPreviewController *) controller
{
return 1;
}
- (id <QLPreviewItem>) previewController: (QLPreviewController *) controller previewItemAtIndex: (NSInteger) index
{
return self;
}
#pragma mark - QLPreviewItem protocol
- (NSURL*)previewItemURL
{
return self.fileUrl;
}
@end
我需要帮助:(
编辑:看到图像,我正在试图实现:
最佳答案
presentOpenInMenuFromRect
是UIDocumentInteractionController
方法。我不认为您在此代码中使用一个,除非您的根视图控制器是UIDocumentInteractionController
,这将非常奇怪。
而不是实例化并呈现QLPreviewController
,而是实例化UIDocumentInteractionController
并呈现与文档图标相对应的rect中的弹出窗口。
为此,请检查UIDocumentInteractionController documentation。您会看到有一个interactionControllerWithURL:
方法,可用于实例化指向文件的UIDocumentInteractionController
。然后,您可以调用presentOpenInMenuFromRect:inView:animated:
以显示所需的弹出窗口。
