EXC_BAD_ACCESS (CODE=2 ,ADDRESS=0Xbf7fff2c) when switching tab ios6 - ios

My code is working fine for iOS 7 but crashes in iOS 6. My app is working fine but the problem occurs when i click on a tab else its working fine.
Checked the link :EXC_BAD_ACCESS While switching tabControllers but no luck.
Below is my code:
- (void)viewDidLoad
{
[super viewDidLoad];
// Do any additional setup after loading the view.
self.webView = [[UIWebView alloc] init];
self.view.backgroundColor = [UIColor colorWithPatternImage:[JLTBackgroundHelper getBackgroundImageForView]];
self.webView.opaque = NO;
self.webView.backgroundColor = [UIColor clearColor];
UIViewController *rootVC = [[UIViewController alloc] init];
rootVC.title = #"Contact JLT Sport";
rootVC.view = self.webView;
self.viewControllers = #[rootVC];
NSString *fileName;
if (UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPad) {
// iPad-specific
fileName = #"contact_ipad";
} else {
// iPhone-specific
fileName = #"contact";
}
NSString *htmlFile = [[NSBundle mainBundle] pathForResource:fileName ofType:#"html" inDirectory:#"Assets/web"];
NSURL *url = [NSURL fileURLWithPath:htmlFile];
NSURLRequest *request =[NSURLRequest requestWithURL:url];
[_webView loadRequest:request];
_webView.delegate= self;
}
//send external URL requests to Safari
- (BOOL) webView:(UIWebView*)wv shouldStartLoadWithRequest:(NSURLRequest*)request navigationType:(UIWebViewNavigationType)navType
{
if (navType == UIWebViewNavigationTypeLinkClicked
&& [request.URL.scheme hasPrefix:#"http"])
{
[[UIApplication sharedApplication] openURL:request.URL];
return NO;
}
return YES;
}
#end
Plese guide/suggest.

try this :
- (void)viewDidLoad
{
[super viewDidLoad];
// Do any additional setup after loading the view.
self.webView = [[UIWebView alloc] init];
self.view.backgroundColor = [UIColor colorWithPatternImage:[JLTBackgroundHelper getBackgroundImageForView]];
self.webView.opaque = NO;
self.webView.backgroundColor = [UIColor clearColor];
UIViewController *rootVC = [[UIViewController alloc] init];
rootVC.title = #"Contact JLT Sport";
rootVC.view = self.webView;
self.viewControllers = #[rootVC];
NSString *fileName;
if (UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPad) {
// iPad-specific
fileName = #"contact_ipad";
} else {
// iPhone-specific
fileName = #"contact";
}
NSString *htmlFile = [[NSBundle mainBundle] pathForResource:fileName ofType:#"html" inDirectory:#"Assets/web"];
NSURL *url = [NSURL fileURLWithPath:htmlFile];
NSURLRequest *request =[NSURLRequest requestWithURL:url];
[self.webView loadRequest:request];
self.webView.delegate= self;
}
if above solution does not work then try this:
Debug with Instrument
Go to Product >> Profile >> All > Zoombies
Press "Record" button on top left corner
Perform your task and when application get EXC_BAD_ACCESS the instrument give that line where the application was being crash.
Also debug in this method to:[JLTBackgroundHelper getBackgroundImageForView];
**Make sure that all variable is being get memory before use it.**
May be the resin is that some method is depreciated in iOS 7.
These are the possible scenario of application is being crash and its solution.

iOS - Navigation Title comes from left when back button is pressed

In my app when I visit certain view controllers and touch the Back button in the navigation bar, the navigation title of the resulting viewcontroller looks to be coming from the upper left corner and it looks ugly.
A picture of such an instance is shown below.
I have set the titles programatically.
Can somebody please tell me why this is happening and how I could fix it? Thanks in advance.

iPad PDF Rendering too small. Not to screen size

I'm trying to fully render a PDF in an iPad webview but the document displays too small and not the full size as to what it should be. The PDF renders perfectly on the iPhone just not the iPad webview. Please let me know if you need more information.
Main View
-(void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
//NSString *url = [chapterFiles objectAtIndex:indexPath.row];
NSURL *url = [NSURL fileURLWithPath:[[NSBundle mainBundle]pathForResource: [chapterFiles objectAtIndex:indexPath.row] ofType:#"pdf"]];
NSLog(#"Selected File: %#",url);
//transfer selected
UIStoryboard *sb = [UIStoryboard storyboardWithName:#"Main_iPhone" bundle:nil];
chapterDetailViewController *detailView = (chapterDetailViewController *)[sb instantiateViewControllerWithIdentifier:#"chapterDetails"];
detailView.url = url;
[self.navigationController pushViewController:detailView animated:YES];
}
Detail View:
//NSString *path = [[NSBundle mainBundle] pathForResource:url ofType:#"pdf"];
//NSURL *targetURL = [NSURL fileURLWithPath:url];
NSURLRequest *siteRequest = [NSURLRequest requestWithURL:url];
[chapterWebView loadRequest:siteRequest];
chapterWebView.delegate = self;
//[chapterWebView setScalesPageToFit:YES];
chapterWebView.scalesPageToFit = YES;
// chapterWebView.contentMode = UIViewContentModeScaleToFill;
// chapterWebView.multipleTouchEnabled = YES;
// chapterWebView.autoresizingMask = UIViewAutoresizingFlexibleWidth | UIViewAutoresizingFlexibleHeight;
// [self.view addSubview:chapterWebView];
}
You are instantiating a view controller on a storyboard whose filename has "iPhone" in it. You're probably instantiating a view controller from the wrong storyboard. Make sure you're initializing the right storyboard for the right device.

screen blacks out when loading a html file in web view iOS

I am trying to load a html file in a web view and the screen blacks out.
Hierachy of view controller are:
View
Web View
Navigation Item
This is the tab and there is navigation controller to present the View Controller.
Code:
- (void)viewDidLoad
{
[super viewDidLoad];
// Do any additional setup after loading the view.
self.webView = [[UIWebView alloc] init];
self.view.backgroundColor = [UIColor colorWithPatternImage:[JLTBackgroundHelper getBackgroundImageForLandingView]];
self.webView.opaque = NO;
self.webView.backgroundColor = [UIColor clearColor];
UIViewController *rootVC = [[UIViewController alloc] init];
rootVC.title = #"Contact JLT Sport";
rootVC.view = self.webView;
self.viewControllers = #[rootVC];
NSString *fileName;
if (UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPad) {
// iPad-specific
fileName = #"contact_ipad";
} else {
// iPhone-specific
fileName = #"contact";
}
NSString *htmlFile = [[NSBundle mainBundle] pathForResource:fileName ofType:#"html" inDirectory:#"Assets/web"];
NSURL *url = [NSURL fileURLWithPath:htmlFile];
NSURLRequest *request =[NSURLRequest requestWithURL:url];
[_webView loadRequest:request];
_webView.delegate= self;
}
- (BOOL) webView:(UIWebView*)wv shouldStartLoadWithRequest:(NSURLRequest*)request navigationType:(UIWebViewNavigationType)navType
{
if (navType == UIWebViewNavigationTypeLinkClicked
&& [request.URL.scheme hasPrefix:#"http"])
{
[[UIApplication sharedApplication] openURL:request.URL];
return NO;
}
return YES;
}
Not sure whats going wrong. tried for more than 5 hours but no luck.
Instead of
self.viewControllers = #[rootVC];
Try this
[self presentViewController:rootVC animated:NO completion:nil];
If presenting the controller in viewDidLoad gives some problem, then do it in viewDidAppear. First of all I'm not clear why you are creating another view controller within viewDidLoad of a controller and adding the subview to that.

-writeToURL is not overwriting the previous write

UPDATE #1: forgot to mention this is running on an iPad app
This is my revised code (still not working, but got rid of the unnecessary code):
NSURL *tmpDirURL = [NSURL fileURLWithPath:NSTemporaryDirectory() isDirectory:YES];
NSURL *fileURL = [[tmpDirURL URLByAppendingPathComponent:#"custImage"] URLByAppendingPathExtension:#"png"];
NSError*writeError = nil;
[client.aClientImage writeToURL:fileURL options:0 error:&writeError];
NSAssert(writeError==nil, writeError);
// write appointment info
NSString *htmlString;
if(client.aClientEMail.length > 0) {
htmlString = [NSString stringWithFormat:NSLocalizedString(#"HTML_STRING1",nil),
client.aClientFirstName,
client.aClientLastName,
client.aClientEMail.length == 0? #"": client.aClientEMail,
client.aClientPrimaryPhone,
apptSelected.aServices,
fileURL];
}
else {
htmlString = [NSString stringWithFormat:NSLocalizedString(#"HTML_STRING2",nil),
client.aClientFirstName,
client.aClientLastName,
client.aClientPrimaryPhone,
apptSelected.aServices,
fileURL];
}
When I look at custImage in the XCode debugger, I see a different image from the previous image, which is correct. However, when it gets time to display the image at fileURL, it's a totally different image than custImage and is the same image that was displayed the first time!
UPDATE #2: I have figured out that fileURL has the correct image, but it is NOT being written to the device the second time (the first image is not being replaced).
UPDATE #3: this is the contents of htmlString that is displayed in the UIWebView popover:
<html><head><style type="text/css"> body {font-family: "Verdana"; font-size: 12;} </style></head><body>
<h2>Rolf Marsh</h2><p>phone: 213-555-1234<p>services: Art, Decals<p><img src="file:///private/var/mobile/Applications/FEE7159E-1FF8-4B94-A446-2A4C72E0AD41/tmp/custImage.png"/></body></html>
Any suggestions on how to fix this?
you never write the data to disk as far as I can see.
Only in the commented out section you attempt to.
Write it in between:
NSURL *tmpDirURL = [NSURL fileURLWithPath:NSTemporaryDirectory() isDirectory:YES];
NSURL *fileURL = [[tmpDirURL URLByAppendingPathComponent:#"custImage"] URLByAppendingPathExtension:#"png"];
//write
NSError*writeError = nil;
[client.aClientImage writeToURL:fileURL options:0 error:&writeError];
NSAssert(writeError==nil, writeError);
//read / use in the html or so
...
Dont forget to reload the web view or whatever you use to show the html
I figured it out... for others that are having the same problem, here is the code that works. Notice that I do NOT save it to a temporary file, since I already have the image in the Core Data entity. Here's the code:
-(void) showExistingAppointmentDetails: (AppointmentInfo *) apptSelected {
// make rectangle to attach popover
CGRect rectangle = CGRectMake( [apptSelected.aPosX floatValue], [apptSelected.aPosY floatValue],
[apptSelected.aPosW floatValue], [apptSelected.aPosH floatValue]);
// see if this is for staff; if so, don't display anything
if([apptSelected.aApptKey isEqual: #"Staff"])
return;
NSPredicate *predicate = ([NSPredicate predicateWithFormat: #"aClientKey == %#", apptSelected.aApptKey ]); // was aApptKey
ClientInfo *client = [ClientInfo MR_findFirstWithPredicate:predicate inContext:localContext];
UIImage *image = [UIImage imageWithData:client.aClientImage]; // image is good <---------
// write appointment info into html string
NSString *htmlString;
if(client.aClientEMail.length > 0) {
htmlString = [NSString stringWithFormat:NSLocalizedString(#"HTML_STRING1",nil),
client.aClientFirstName,
client.aClientLastName,
client.aClientEMail.length == 0? #"": client.aClientEMail,
client.aClientPrimaryPhone,
apptSelected.aServices,
[self htmlForPNGImage:image]];
}
else {
htmlString = [NSString stringWithFormat:NSLocalizedString(#"HTML_STRING2",nil),
client.aClientFirstName,
client.aClientLastName,
client.aClientPrimaryPhone,
apptSelected.aServices,
[self htmlForPNGImage:image]];
}
UIViewController* popoverContent = [[UIViewController alloc] init];
UIView* popoverView = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 250, 300)];
popoverView.backgroundColor = [UIColor colorWithWhite:(CGFloat)1.0 alpha:(CGFloat)1.0]; // frame color?
popoverContent.view = popoverView;
//resize the popover view shown in the current view to the view's size
popoverContent.contentSizeForViewInPopover = CGSizeMake(250, 300);
// add the UIWebView for RichText
UIWebView *webView = [[UIWebView alloc] initWithFrame:popoverView.frame];
webView.backgroundColor = [UIColor whiteColor]; // change background color here
// add the webView to the popover
[webView loadHTMLString:htmlString baseURL:[NSURL URLWithString:nil]];
[popoverView addSubview:webView];
// if previous popoverController is still visible... dismiss it
if ([popoverController isPopoverVisible]) {
[popoverController dismissPopoverAnimated:YES];
}
//create a popover controller
popoverController = [[UIPopoverController alloc] initWithContentViewController:popoverContent];
[popoverController presentPopoverFromRect:rectangle inView:self
permittedArrowDirections:UIPopoverArrowDirectionAny animated:YES];
}
- (NSString *) htmlForPNGImage:(UIImage *) image {
NSData *imageData = UIImagePNGRepresentation(image);
NSString *imageSource = [NSString stringWithFormat:#"data:image/png;base64,%#",[imageData base64Encoding]];
return [NSString stringWithFormat:#"%#", imageSource];
}
