Question

¿Podemos abrir el archivo pdf desde UIWebView?

Si alguien ha implementado esto, por favor ayudame.

Cualquier fragmento de código o cualquier enlace web ayudaría.

Answer 1

Sí, esto se puede hacer con UIWebView.

Si está intentando mostrar un archivo PDF que reside en un servidor en alguna parte, simplemente puede cargarlo en su vista web directamente:

C objetivo

UIWebView *webView = [[UIWebView alloc] initWithFrame:CGRectMake(10, 10, 200, 200)];
NSURL *targetURL = [NSURL URLWithString:@"https://www.example.com/document.pdf"];
NSURLRequest *request = [NSURLRequest requestWithURL:targetURL];
[webView loadRequest:request];
[self.view addSubview:webView];

Rápido

let webView = UIWebView(frame: CGRect(x: 10, y: 10, width: 200, height: 200))
let targetURL = NSURL(string: "https://www.example.com/document.pdf")! // This value is force-unwrapped for the sake of a compact example, do not do this in your code
let request = NSURLRequest(URL: targetURL)
webView.loadRequest(request)
view.addSubview(webView)

O si tiene un archivo PDF incluido con su aplicación (en este ejemplo llamado "document.pdf"):

C objetivo

UIWebView *webView = [[UIWebView alloc] initWithFrame:CGRectMake(10, 10, 200, 200)];
NSURL *targetURL = [[NSBundle mainBundle] URLForResource:@"document" withExtension:@"pdf"];
NSURLRequest *request = [NSURLRequest requestWithURL:targetURL];
[webView loadRequest:request];
[self.view addSubview:webView];

Rápido

let webView = UIWebView(frame: CGRect(x: 10, y: 10, width: 200, height: 200))
let targetURL = NSBundle.mainBundle().URLForResource("document", withExtension: "pdf")! // This value is force-unwrapped for the sake of a compact example, do not do this in your code
let request = NSURLRequest(URL: targetURL)
webView.loadRequest(request)
view.addSubview(webView)

Una actualización de la respuesta de Martin Alléus, para obtener la pantalla completa, ya sea un teléfono o un iPad sin tener que codificarlo:

CGRect rect = [[UIScreen mainScreen] bounds];
CGSize screenSize = rect.size;
UIWebView *webView = [[UIWebView alloc] initWithFrame:CGRectMake(0,0,screenSize.width,screenSize.height)];
NSString *path = [[NSBundle mainBundle] pathForResource:@"pdf" ofType:@"pdf"];
NSURL *targetURL = [NSURL fileURLWithPath:path];
NSURLRequest *request = [NSURLRequest requestWithURL:targetURL];
[webView loadRequest:request];
[self.view addSubview:webView];

Answer 3

Versión Swift:

if let docPath = NSBundle.mainBundle().pathForResource("sample", ofType: "pdf") {
let docURL = NSURL(fileURLWithPath: docPath)
webView.loadRequest(NSURLRequest(URL: docURL))
}

Answer 4

Webviews también puede cargar el pdf usando el método loadData , si lo adquiere como NSData:

[self.webView loadData:self.pdfData
MIMEType:@"application/pdf"
textEncodingName:@"UTF-8"
baseURL:nil];

Answer 5

use esto para abrir el archivo pdf en la vista web

NSString *path = [[NSBundle mainBundle] pathForResource:@"mypdf" ofType:@"pdf"];
NSURL *targetURL = [NSURL fileURLWithPath:path];
NSURLRequest *request = [NSURLRequest requestWithURL:targetURL];
UIWebView *webView=[[UIWebView alloc] initWithFrame:CGRectMake(0, 0, 300, 300)];
[[webView scrollView] setContentOffset:CGPointMake(0,500) animated:YES];
[webView stringByEvaluatingJavaScriptFromString:[NSString stringWithFormat:@"window.scrollTo(0.0, 50.0)"]];
[webView loadRequest:request];
[self.view addSubview:webView];
[webView release];

NSString *type=[tempDictLitrature objectForKey:@"type"];
NSString *path=[[NSBundle mainBundle]pathForResource:fileName ofType:type inDirectory:folderName];
NSURL *targetURL = [NSURL fileURLWithPath:path];
NSURLRequest *request = [NSURLRequest requestWithURL:targetURL];
webView=[[UIWebView alloc] initWithFrame:CGRectMake(0, 0, 1024, 730)];
[webView setBackgroundColor:[UIColor lightGrayColor]];
webView.scalesPageToFit = YES;
[[webView scrollView] setContentOffset:CGPointZero animated:YES];
[webView stringByEvaluatingJavaScriptFromString:[NSString stringWithFormat:@"window.scrollTo(0.0, 50.0)"]];
[webView loadRequest:request];
[self.view addSubview:webView];
