Problem with a NSString that equals to (null)
- by Guy Dor
Hi,
I have an UIViewController named MainViewController
I have another UIViewController named LeftSharingViewController;
I would like to get and use the NSString from MainViewController in my LeftSharingViewController
I have a problem, I always get (null) instead of the NSString wanted value.
Here's my code and how does the NSString get it's value
MainViewController:
- (void)webViewDidFinishLoad:(UIWebView *)webView {
leftWebViewString = [NSString stringWithString:leftWebView.request.URL.absoluteString];
}
LeftSharingViewController.h:
#import <UIKit/UIKit.h>
#import "MainViewController.h"
#import <MessageUI/MessageUI.h>
#import <MessageUI/MFMailComposeViewController.h>
@class MainViewController;
@interface LeftSharingViewController : UIViewController <MFMailComposeViewControllerDelegate> {
MainViewController *mainViewController;
NSString *leftWebViewUrl;
}
@property (nonatomic, retain) MainViewController *mainViewController;
@property (nonatomic, retain) NSString *leftWebViewUrl;
@end
LeftSharingViewController.m:
#import "LeftSharingViewController.h"
#import "MainViewController.h"
@implementation LeftSharingViewController
@synthesize mainViewController;
@synthesize leftWebViewUrl;
- (void)viewWillAppear:(BOOL)animated {
self.leftWebViewUrl = self.mainViewController.leftWebViewString;
}
#pragma mark -
#pragma mark Compose Mail
-(void)displayComposerSheet
{
MFMailComposeViewController *mailPicker = [[MFMailComposeViewController alloc] init];
mailPicker.mailComposeDelegate = self;
[mailPicker setSubject:@"Check Out This Website!"];
[mailPicker setMessageBody:[NSString stringWithFormat:@"Take a look at this site:%@", leftWebViewUrl] isHTML:YES];
mailPicker.modalPresentationStyle = UIModalPresentationFormSheet;
[self presentModalViewController:mailPicker animated:YES];
[mailPicker release];
}
Thanks!
