iPhone SDK - (void)viewDidLoad { } - Show Progress
- by Hank Brekke
I have a long - (void)viewDidLoad { } function that uses the internet to load a page, and whenever the application loads the URL, the screen is black. I have a UIActivityIndicator setup to show that the address is loading, but I don't know how to prevent it from seeming as if the application is not responding, and I don't want to show the network activity indicator [[UIApplication sharedApplication] setNetworkActivityIndicatorVisible:YES]; because the screen will still be black, just with a loader in the top corner. My code is below:
- (void)viewDidLoad {
NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults];
email.text = [defaults objectForKey:@"mom_email"];
pass.text = [defaults objectForKey:@"mom_pass"];
if (email.text != nil && pass.text != nil) {
[self login:loginBtn];
}
}
- (IBAction)login:(id)sender {
[email resignFirstResponder];
[pass resignFirstResponder];
[loader startAnimating]; // Does nothing though
NSString *em = (NSString *)CFURLCreateStringByAddingPercentEscapes(NULL,(CFStringRef)email.text,NULL,(CFStringRef)@"!*'();:@&=+$,/?%#[]",kCFStringEncodingUTF8);
NSString *ps = (NSString *)CFURLCreateStringByAddingPercentEscapes(NULL,(CFStringRef)pass.text,NULL,(CFStringRef)@"!*'();:@&=+$,/?%#[]",kCFStringEncodingUTF8);
NSURL *url = [[NSURL alloc] initWithScheme:@"http" host:@"localhost" path:[[NSString alloc] initWithFormat:@"/app/login.php?email=%@&pass=%@", em, ps]];
NSURLRequest *request = [NSURLRequest requestWithURL:url];
NSData *data = [NSURLConnection sendSynchronousRequest:request returningResponse:nil error:nil];
NSString *loginResult = [[NSString alloc] initWithData:data encoding:NSASCIIStringEncoding];
[loader stopAnimating];
NSRange range = [loginResult rangeOfString:@"1"];
if (range.location != NSNotFound) {
[self dismissModalViewControllerAnimated:YES]; // Doesn't do anything if function called from viewDidLoad
}
}
