Hi folks
Sorry if this is an easy one. Basically, here is my code:
MainViewController.h:
//
// MainViewController.h
// Site

#import "FlipsideViewController.h"
@interface MainViewController : UIViewController <UIWebViewDelegate, FlipsideViewControllerDelegate> {
IBOutlet UIWebView *webView;
IBOutlet UIActivityIndicatorView *spinner;
}
- (IBAction)showInfo;
@property(nonatomic,retain) UIWebView *webView;
@property(nonatomic,retain) UIActivityIndicatorView *spinner;
@end
MainViewController.m:
//

#import "MainViewController.h"
#import "MainView.h"
@implementation MainViewController
@synthesize webView;
@synthesize spinner;
- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil {
if (self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil]) {
// Custom initialization
}
return self;
}
// Implement viewDidLoad to do additional setup after loading the view, typically from a nib.
- (void)viewDidLoad {
NSURL *siteURL;
NSString *siteURLString;
siteURLString=[[NSString alloc] initWithString:@"http://www.site.com"];
siteURL=[[NSURL alloc] initWithString:siteURLString];
[webView loadRequest:[NSURLRequest requestWithURL:siteURL]];
[siteURL release];
[siteURLString release];
[super viewDidLoad];
}
- (void)flipsideViewControllerDidFinish:(FlipsideViewController *)controller {
[self dismissModalViewControllerAnimated:YES];
}
- (void)webViewDidFinishLoad:(UIWebView *)webView {
[spinner stopAnimating];
spinner.hidden=FALSE;
NSLog(@"viewDidFinishLoad went through nicely");
}
- (void)webViewDidStartLoad:(UIWebView *)webView {
[spinner startAnimating];
spinner.hidden=FALSE;
NSLog(@"viewDidStartLoad seems to be working");
}
- (IBAction)showInfo {
FlipsideViewController *controller = [[FlipsideViewController alloc] initWithNibName:@"FlipsideView" bundle:nil];
controller.delegate = self;
controller.modalTransitionStyle = UIModalTransitionStyleFlipHorizontal;
[self presentModalViewController:controller animated:YES];
[controller release];
}
- (void)didReceiveMemoryWarning {
// Releases the view if it doesn't have a superview.
[super didReceiveMemoryWarning];
// Release any cached data, images, etc that aren't in use.
}
- (void)viewDidUnload {
// Release any retained subviews of the main view.
// e.g. self.myOutlet = nil;
}
- (void)dealloc {
[spinner release];
[webView release];
[super dealloc];
}
@end
Unfortunately nothing is ever written to my log, and for some reason the Activity Indicator never seems to appear. What's going wrong here?
Thanks folks
Jack
