iPhone 開發筆記10: 利用 UIWebView 讀取 PDF 檔案

A. 新增一個 View-based Project(ex: viewPDF).

B. 在 Resources 裡,  新增一個 PDF 檔(ex: top.pdf).

C. 在 Interface Builder 的 View 裡, 新增一個 UIWebView.

-----------------------------------------------------------------------------------------------------------------

D. 調整 viewPDFViewController.h 如下:
#import <UIKit/UIKit.h>

@interface viewPDFViewController : UIViewController {
    UIWebView *myUIWebView;

}

@property (nonatomic, retain) IBOutlet UIWebView *myUIWebView;

@end

-----------------------------------------------------------------------------------------------------------------

E. 調整 viewPDFViewController.m 如下:
#import "viewPDFViewController.h"

@implementation viewPDFViewController

@synthesize myUIWebView;

........

// Implement viewDidLoad to do additional setup after loading the view, typically from a nib.
- (void)viewDidLoad {
    [super viewDidLoad];
   
    NSString *pdfPath = [[NSBundle mainBundle] pathForResource:@"toc" ofType:@"pdf"];

    NSURL *pdfURL = [NSURL fileURLWithPath:pdfPath];

    NSURLRequest *pdfRequest = [NSURLRequest requestWithURL:pdfURL];

    [myUIWebView loadRequest:pdfRequest];
}

- (void)viewDidUnload {
    // Release any retained subviews of the main view.
    // e.g. self.myOutlet = nil;
    self.myUIWebView = nil;
}

- (void)dealloc {
    [myUIWebView release];
   
    [super dealloc];
}

-----------------------------------------------------------------------------------------------------------------

F. 在 Interface Builder , 將 File's Owner 的 Outlets: myUIWebView 連結到 View 下的 UIWebView.
