활동 표시기가 PDF에 표시되지 않습니다. uiwebview로드

Question

uiwebview가있는 응용 프로그램을 개발 중이며 해당 webview에서 uiwebview가 Java를 통해 원시 메소드를 호출 할 때 로컬 pdf 파일을로드해야합니다. 그리고 내가 성공적으로 일을하지만 내가 webisete 활동 표시기를 통해 탐색 할 때 잘 표시하지만 네이티브 함수 호출 및 uiwebview에서 PDF로드 할 때 그것은 URL에서 PDF로드하는 동안 doesnot 보여줍니다. 내 코드를 여기에 게시하도록하겠습니다. UIWebViewDelegate 방법에

#import "ViewController.h" 

@interface ViewController() 

@end 

@implementation ViewController 

@synthesize webPage; 
- (BOOL) shouldAutorotate{ 
    return NO; 
} 

- (void)viewDidLoad 
{ 
    [super viewDidLoad]; 
    webLink = @"http://url.com/m/"; 
    liNk = webLink; 
    [webPage loadRequest:[NSURLRequest requestWithURL:[NSURL URLWithString:liNk]]]; 
    webPage.backgroundColor = [UIColor blackColor]; 
    //[[webPage.subviews objectAtIndex:0] setBounces:NO]; 
    [(UIScrollView*)[webPage.subviews objectAtIndex:0] setShowsVerticalScrollIndicator:NO]; 
    [webPage addSubview:activity]; 
    timer = [NSTimer scheduledTimerWithTimeInterval:(1.0/2.0) target:self selector:@selector(loading) userInfo:nil repeats:YES]; 
    webPage.delegate = self; 
} 
- (BOOL)webView:(UIWebView *)webView shouldStartLoadWithRequest:(NSURLRequest *)request navigationType:(UIWebViewNavigationType)navigationType 
{ 
    if ([[[request URL] absoluteString] hasPrefix:@"ios:"]) { 
     // Call the given selector 
     [self performSelector:@selector(webToNativeCall)]; 
     return NO; 
    } 
    return YES; 

} 
- (void)webToNativeCall 
{ 
     NSString *pdfurl = @"http://url.com/mypdf.pdf"; 
     NSData *pdfData = [[NSData alloc] initWithContentsOfURL:[NSURL URLWithString:pdfurl]]; 
     NSString *resourceDocPath = [[NSString alloc] initWithString:[[[[NSBundle mainBundle] resourcePath] stringByDeletingLastPathComponent]stringByAppendingPathComponent:@"Documents"]]; 
     NSString *filePath = [resourceDocPath stringByAppendingPathComponent:@"mypdf.pdf"]; 
     [pdfData writeToFile:filePath atomically:YES]; 
     // Now create Request for the file that was saved in your documents folder 
     NSURL *url = [NSURL fileURLWithPath:filePath]; 
     NSURLRequest *requestObj = [NSURLRequest requestWithURL:url]; 
     [webPage setUserInteractionEnabled:YES];
