IOS loading files in PDF format

Can be loaded in a way more, for the time being summed up two kinds:

Locally piloted into a PDF file

Type 1: Load with UIWebView

UIWebView *webview = [[UIWebView alloc] Initwithframe:cgrectmake (00, Self.view.bounds.size.width, Self.view.bounds.size.height)];    [Self.view Addsubview:webview];     *path = [[NSBundle mainbundle] Pathforresource:@ " based on Apache+jmeter" ofType:@ "  PDF"];     *url = [Nsurl Fileurlwithpath:path];     *request = [Nsurlrequest requestwithurl:url];    [WebView loadrequest:request];

Type 2: Frame Quicklook with preview file of the system

First import the frame quicklook.framework

Introducing Header Files #import <QuickLook/QuickLook.h>

Instantiating an Object

  Qlpreviewcontroller *myqlpreviewcontroller = [[Qlpreviewcontroller alloc]init];    Myqlpreviewcontroller. delegate = self;     = self;    [Myqlpreviewcontroller Setcurrentpreviewitemindex: 0 ];     // Here you can go with the navigation bar, or you can jump without the navigation bar, you can also get the view to add    [Self Presentviewcontroller:myqlpreviewcontroller animated:yes completion:^{        NSLog (@ " Jump Completion " );    }];

Declaring an agent

<QLPreviewControllerDelegate,QLPreviewControllerDataSource>

Implementation protocol

#pragma mark-qlpreviewcontroller agent-(Nsinteger) Numberofpreviewitemsinpreviewcontroller: (Qlpreviewcontroller *) controller{    return 1;} -(id<qlpreviewitem>) Previewcontroller: (Qlpreviewcontroller *) controller previewitematindex: (NSInteger) index{        NSString *path = [[NSBundle Mainbundle] pathforresource:@ "based on Apache+jmeter" oftype:@ "PDF"];    return [Nsurl Fileurlwithpath:path];} -(void) Previewcontrollerdiddismiss: (Qlpreviewcontroller *) controller{    NSLog (@ "Preview interface has disappeared");} File internal link Click No external jump-(BOOL) Previewcontroller: (Qlpreviewcontroller *) controller shouldopenurl: (nsurl *) URL Forpreviewitem: (id <QLPreviewItem>) item{    return NO;}

At this end, the loading process may be slow, after all, a local PDF file needs to be loaded;

Two ways to compare can be seen, the first kind of loading is more convenient, but the memory consumption of more, the second memory consumption of less, I actually measured the difference of 20MB (with the simulator).
