UIWebView autosize issue only on iOS 4.3
- by troop231
I am trying to figure out how to fix this bug that only occurs on iOS 4.3. When the application launches, it displays a PDF that is scaled to fit in the UIWebView. It behaves perfectly until you pinch to zoom on the document, and then rotate it, leaving behind a black area. If you don't pinch to zoom, it doesn't leave the black area. I don't understand why this is a iOS 4.3 only issue.
Screenshot of the issue: I've been trying to solve this problem awhile now, and would greatly appreciate your help. Thank you.
Screenshots of the .xib settings:
The code I'm using is:
.h:
#import <UIKit/UIKit.h>
@interface ViewController : UIViewController
{
UIWebView *webView;
}
@property (nonatomic) IBOutlet UIWebView *webView;
@end
.m:
#import "ViewController.h"
@interface ViewController ()
@end
@implementation ViewController
@synthesize webView;
- (BOOL)shouldAutorotateToInterfaceOrientation:
(UIInterfaceOrientation)interfaceOrientation
{
if (UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPad) {
return YES;
} else {
return (interfaceOrientation !=
UIInterfaceOrientationPortraitUpsideDown);
}
}
- (void)viewDidLoad
{
[super viewDidLoad];
NSString *urlAddress = [[NSBundle mainBundle] pathForResource:@"test" ofType:@"pdf"];
NSURL *url = [NSURL fileURLWithPath:urlAddress]; NSURLRequest *requestObj = [NSURLRequest requestWithURL:url];
[webView loadRequest:requestObj];
}
- (void)didReceiveMemoryWarning
{
[super didReceiveMemoryWarning];
}
@end
