在我的一个视图中,我只想在UIWebView中显示pdf文件.
#import <UIKit/UIKit.h>
@interface FCOMViewController : UIViewController
{IBOutlet UIWebView *fcomWebView;}
//flag to denote if this is first time the app is run
@property (nonatomic) BOOL firstRun;
@end
- (void)viewDidLoad {
//Show the procedures PDF
NSString *path = [[NSBundle mainBundle] pathForResource:@"b777normalprocedures" ofType:@"pdf"];
NSURL *url = [NSURL fileURLWithPath:path];
NSURLRequest *request = [NSURLRequest requestWithURL:url];
[fcomWebView loadRequest:request];
[fcomWebView setScalesPageToFit:YES];
该应用程序启动正常,不崩溃或任何东西.引用出口已设置,但不显示PDF.控制台说：
DiskImageCache: Could not resolve the absolute path of the old
directory. Failed to find PDF header: `%PDF’ not found.
pdf在项目目录中,我已经仔细检查过它是否正确写入.
我能在这做什么？任何帮助,将不胜感激.
解决方法
如果您的目标是iOS 8.0,请尝试此操作：
NSString *path = [[NSBundle mainBundle] pathForResource:@"b777normalprocedures" ofType:@"pdf"]; NSURL *targetURL = [NSURL fileURLWithPath:path]; NSData *pdfData = [[NSData alloc] initWithContentsOfURL:targetURL]; [_webView loadData:pdfData MIMEType:@"application/pdf" textEncodingName:@"utf-8" baseURL:nil];
