  • iphone getting hours/min/seconds app crashes.

    - by coure06
    i have this code in my overridden drawRect method NSDate *date = [NSDate date]; NSCalendar *calendar = [NSCalendar currentCalendar]; unsigned int unitFlags = NSHourCalendarUnit|NSMinuteCalendarUnit|NSSecondCalendarUnit; NSDateComponents *comp = [calendar components:unitFlags fromDate:date]; NSInteger h = [comp hour]; NSInteger m = [comp minute]; NSInteger s = [comp second]; NSLog(@"%i,%i,%i", h,m,s); NSLog(@"test"); [date release]; [calendar release]; [comp release]; I am calling drawRect using setNeedsDisplay from my custom method (timer based after each 1 secon). It runs only once and then app exit automatically. If i comment out all the code and just write NSLog(@"test"); then application works ok, it logs "test" after each 1 sec.

  • How to check Internet status in iPhone

    - by Radix
    Hello; I wanted to check whether internet is connected or not using either the SystemConfiguration or the CFNetwork i am not quite sure which one. Then i want to know that if the internet is connected then is it connected through wifi or not. I tried an example where i used the below code -(IBAction) shownetworkStatus { NSURL *url = [NSURL URLWithString:@"www.google.com"]; if (url!=NULL) { lbl.text = @"Connected"; } else { lbl.text = @"notConnected"; } } some say that its not valid as per apple and you have to use the SystemConfiguration Framework, Please let me know what needs to be done. Also i personally think that what i am doing in the above code is not proper as if one day google may also be down due to maintenance or some other factors. Also if you could provide me a link where i could display the name of the WIFI network then it would be really cool. I searched the internet then i got these Reachability.h code which again is a bouncer as i wana learn the concepts not copy paste them Thanks and Regards Radix

  • iphone best practice, how to load multiple high quality images

    - by bennythemink
    Hi guys and girls, I have about 20-ish high quality images (~3840x5800 px) that I need to load in a simple gallery type app. The user clicks a button and the next image is loaded into the UIImageView. I currently use [UIImage imageWithContentsOfFile:] which takes about 6 seconds to load each image in the simulator :( if I use [UIImage imageNamed:] it takes even longer to load but caches the images which means its quicker if the user wishes to see the same images again. But it may cause memory problems later with all that caching crashing my app. I want to know whats the best practice for loading these? I'm experimenting with reducing image file size as much as is possible but I really need them to be high quality image for the purpose of the app (zoomable, etc.). Thanks for any advice

If you have some tips to achieve a good insert, do not hesitate ;) Thank you for your time, Gotye.

  • iPhone audio Filter Question

    - by Joe
    Okay, I am going to try to make this totally not a "plz send teh codez kthxbai" I am considering an app which takes sound (eventually an audio track) and applies an audio filter to it. So I can play sounds with AudioServicesPlaySystemSound via AudioToolbox framework just fine. What I need is a very simple example of how I might take a sound and apply (for instance) midrange boost etc. Actually the kind of alteration is irrelevant -- if I can get my head around how the alteration is done I can figure out the rest. I am just finding both docs and examples of altering audio in code to be very scarce. Thanks for any help!

  • POST and multiple submit buttons on form (iphone)

    - by Jonathan
    NSString *reqURL = [NSString stringWithFormat:@"%@/login",SERVER_URL]; NSMutableURLRequest *req = [[NSMutableURLRequest alloc]initWithURL:[NSURL URLWithString:reqURL]]; [req setValue:@"application/x-www-form-urlencoded" forHTTPHeaderField:@"content-type"]; NSData *myRequestData = [NSData dataWithBytes:[@"username=whatever&password=whatever" UTF8String] length: [@"username=whatever&password=whatever" length]]; [req setHTTPMethod: @"POST"]; [req setHTTPBody: myRequestData]; NSData *returnData = [NSURLConnection sendSynchronousRequest:req returningResponse: nil error: nil]; NSString *html = [[NSString alloc] initWithData:returnData encoding:NSUTF8StringEncoding]; I got this code from another question I asked. But what happens if there is more than one submit button. I really have no idea how to ask this question. An example of such situation is on the logout page for this site. There are no fields to enter data into, but there are 2 submit buttons. How can I "simulate clicking" on one of those buttons using code like the above (so not using a UIWebView)

  • iphone selecting a row to change view

    - by Rob J
    I have created the view Controllers and attached those to control their respective views. I can't figure out how to make the following code to go the right views though. (This is in the root view controller:) - (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath { RunViewController *runViewController = [[RunViewController alloc] initWithNibName:@"RunView" bundle:[NSBundle mainBundle]]; CalcViewController *calcViewController = [[CalcViewController alloc] initWithNibName:@"CalcView" bundle:[NSBundle mainBundle]]; PushViewController *pushViewController = [[PushViewController alloc] initWithNibName:@"PushView" bundle:[NSBundle mainBundle]]; SitViewController *sitViewController = [[SitViewController alloc] initWithNibName:@"SitView" bundle:[NSBundle mainBundle]]; TimerViewController *timerViewController = [[TimerViewController alloc] initWithNibName:@"TimerView" bundle:[NSBundle mainBundle]]; [self.navigationController pushViewController:runViewController animated:YES]; [runViewController release]; [self.navigationController pushViewController:pushViewController animated:YES]; [pushViewController release]; [self.navigationController pushViewController:sitViewController animated:YES]; [sitViewController release]; [self.navigationController pushViewController:timerViewController animated:YES]; [timerViewController release]; [self.navigationController pushViewController:calcViewController animated:YES]; [calcViewController release]; runViewController = nil; pushViewController = nil; sitViewController = nil; timerViewController = nil; calcViewController = nil; } Each time I select any of the rows in the table - all of the views come up. How do I arrange them to only open the view that it is supposed to?

  • Pattern for iPhone background loading during init?

    - by Rob S.
    Hi everyone, I'm currently kicking off a background thread to do some REST queries in my app delegate's didFinishLaunchingWithOptions. This thread creates some objects and populates the model as the rest of the app continues to load (because I don't block, and didFinishLaunchingWithOptions returns YES). I also put up a loading UIViewController 'on top' of the main view that I tear down after the background initialization is complete. My problem is that I need to notify the first view (call it the Home view) that the model is ready, and that it should populate itself. The trick is that the background download could have finished before Home.viewDidAppear is called, or any of the other Home.initX methods. I'm having difficulty synchronizing all of this and I've thought about it long enough that it feels like I'm barking up the wrong tree. Are there any patterns here for this sort of thing? I'm sure other apps start by performing lengthy operations with loading screens :) Thanks!
