  • How to programaticly access min and Max values defined in a core-data model designed with XCode ?

    - by Xav
    I was expecting to find that in the NSAttributeDescription class, but only the default value is there. Behind the scene I tought a validationPredicate was created but trying to reach it using NSDictionary* dico= [[myManagedObject entity] propertiesByName]; NSAttributeDescription* attributeDescription=[dico objectForKey:attributeKey]; for (NSString* string in [attributeDescription validationWarnings]) just get me nowhere, no validationWarnings, no validationPredicates... any thoughts on this ? Edit1: It seems that getting the entity straight from the managedObject doesn't give you the full picture. Getting the Entity from the NSManagedObjectModel permits to reach the validationWarnings & validationPredicates...

  • APNS Sending Frequent Notifications to Device

    - by user564447
    I'm trying to mimic a pager with my app by sending push notifications to the user until he or she responds. My thought was to send a push every few seconds and play the default sound on arrival. Not perfect, but better than nothing. It's working all right. However, I am finding that the sound starts to stutter/interrupt a bit after a few notifications have been sent -- as if it's trying to play the sound more than once. This happens even if I only send the push every 10 seconds. I just tested it at 20 second intervals and even then it starts to sound interrupted after about 10 times. Any idea how to resolve this so each message plays the sound crisply? p.s. Testing performed on an iPad.

  • Why does initWithFrame have the wrong frame value?

    - by greypoint
    I have a subclass of UIButton called INMenuCard and I am overriding the initWithFrame to include an activity indicator. The menuCard places correctly but any internal reference to "frame" give me "inf,inf,0,0" which means my activityIndicator subview is not placed correctly. What might I be missing? @implementation INMenuCard - (id)initWithFrame:(CGRect)frame { if (self = [super initWithFrame:frame]) { CGRect innerFrame = CGRectInset(frame, 50.0f, 100.0f); activityIndicator = [[UIActivityIndicatorView alloc] initWithFrame:innerFrame]; activityIndicator.activityIndicatorViewStyle = UIActivityIndicatorViewStyleWhite; [self addSubview:activityIndicator]; } return self; } I am instantiating INMenuCard with (debugging shows the CGRect values are correct): CGRect cardFrame = CGRectMake(cardX, cardStartY, cardWidth, cardHeight); INMenuCard *menuCard = [[INMenuCard buttonWithType:UIButtonTypeCustom] initWithFrame:cardFrame]; [theView addSubView:menuCard];

  • Value from UISlider method?

    - by fuzzygoat
    Can anyone point me in the right direction regarding sliders, the version below was my first attempt (the range is 0.0 - 100.0) The results I get are not right. // Version 1.0 -(IBAction)sliderMoved:(id)sender { NSLog(@"SliderValue ... %d",(int)[sender value]); } // OUTPUT: // [1845:207] SliderMoved ... -1.991753 // [1845:207] SliderMoved ... 0.000000 // [1845:207] SliderMoved ... 0.000000 // [1845:207] SliderMoved ... 32768.000435 With the version below I get the values I expect, what am I missing in version_001? // Version 2.0 -(IBAction)sliderMoved:(UISlider *)sender { NSLog(@"SliderValue ... %d",(int)[sender value]); } // OUTPUT: // [1914:207] SliderMoved ... 1 // [1914:207] SliderMoved ... 2 // [1914:207] SliderMoved ... 3 // [1914:207] SliderMoved ... 4 cheers Gary

  • Save Values AUTOMATICALLY with NSUserDefaults

    - by Edouard Tarter
    I have an app with two UITextFields, where the user enters an integer, and then a method is called with the values the user enters. But when I completely close the app, the values are deleted. I want to change it to save the value the user entered when it closes, and loads it up when the app is re-opened. I tried this with NSUserDefault, and it worked fine (with save and load button), but I want it to make it automatically, without pressing any buttons. I saw some other people do it with the basic methods in the AppDelegate.m, but I don't know anything about that, therefore I didn't understand it at all. I saw MANY tutorials online, but I didn't understand any of them, please help, and give a detailed answer, thanks :)

  • Couldn't I just pass an copied string to an Core Data property?

    - by dontWatchMyProfile
    The docs say: The default implementation does not copy attribute values. If the attribute value may be mutable and implements the NSCopying protocol (as is the case with NSString, for example), you can copy the value in a custom accessor to help preserve encapsulation (for example, in the case where an instance of NSMutableString is passed as a value). So instead of getting into trouble and inconvenience with overwriting accessors in my NSManagedObject subclass, couldn't I simply do something like this? myManagedObject.firstName = [[firstNameMutableStr copy] autorelease]; This would have the exact same effect, or not? The dynamic implementation would retain that anyways ... so.... why not the easy way?

  • 'Unable to read symbols' error

    - by cannyboy
    When I 'Build and Go' on the device, the console shows: warning: Unable to read symbols for ""/Users/Steve/Blue/build/Debug-iphoneos"/Blue.app/Blue" (file not found). warning: Unable to read symbols for ""/Users/Steve/Blue/build/Debug-iphoneos"/Blue.app/Blue" (file not found). Is this something I should worry about? If so, where should I look to find the root of the issue? The app works OK, but I'm just worried that this might be an AppStore approval issue.

  • novice needing help on shuffeling an array

  • Problems with UITableView when loading the view into the main window

    - by GuidoMB
    I've created a sub class of UITableViewController named LoginViewController with the XIB file using XCode. Then I opened the XIB file with IB and set the table's style to grouped. Finally I wrote the following code: - (void)applicationDidFinishLaunching:(UIApplication *)application { LoginViewController *loginViewController = [[LoginViewController alloc] initWithNibName:@"LoginViewController" bundle:[NSBundle mainBundle]]; [window addSubview: loginViewController.view]; window.backgroundColor = [UIColor blueColor]; [window makeKeyAndVisible]; [window layoutSubviews]; } I set the window's background color to blue for you to see what the problem is. I put a link to the screenshot If I don't use the table style grouped the problem does not occur

  • Is it okay for multiple objects to retain the same object in Objective-C/Cocoa?

    - by Andrew Arrow
    Say I have a tableview class that lists 100 Foo objects. It has: @property (nonatomic, retain) NSMutableArray* fooList; and I fill it up with Foos like: self.fooList = [NSMutableArray array]; while (something) { Foo* foo = [[Foo alloc] init]; [fooList addObject:foo]; [foo release]; } First question: because the NSMutableArray is marked as retain, that means all the objects inside it are retained too? Am I correctly adding the foo and releasing the local copy after it's been added to the array? Or am I missing a retain call? Then if the user selects one specific row in the table and I want to display a detail Foo view I call: FooView* localView = [[FooView alloc] initWithFoo:[self.fooList objectAtIndex:indexPath.row]]; [self.navigationController pushViewController:localView animated:YES]; [localView release]; Now the FooView class has: @property (nonatomic, retain) Foo* theFoo; so now BOTH the array is holding on to that Foo as well as the FooView. But that seems okay right? When the user hits the back button dealloc will be called on FooView and [theFoo release] will be called. Then another back button is hit and dealloc is called on the tableview class and [fooList release] is called. You might argue that the FooView class should have: @property (nonatomic, assign) Foo* theFoo; vs. retain. But sometimes the FooView class is called with a Foo that's not also in an array. So I wanted to make sure it was okay to have two objects holding on to the same other object.

  • tableView resize problem when pushing another view while keyboard is showing

    - by Rollin_s
    I have a tableview controller under a navigation controller. Some of my table cells contain text fields, so when I tap on them, a keyboard will show up and automatically resize (shrink) the bounds of my tableview. The bounds is then restored when the keyboard is dismissed programmatically by calling resignFirstResponder on my text field. Some of my cells would push a new view controller into the view stack when tapped on, so I first resign my current textfield before pushing the view controller: - (NSIndexPath *)tableView:(UITableView *)tableView willSelectRowAtIndexPath:(NSIndexPath *)indexPath { if (currentEditingTextField != nil) { [currentEditingTextField resignFirstResponder]; currentEditingTextField = nil; } return indexPath; } The problem is when I navigate back to my table view, the bounds of the tableview is sized as if the keyboard is still there. I know this because the scroll indicator only reaches right above where the keyboard was and there is empty view space below the table view. Anybody experienced this and know of a solution? Thanks

  • Question regrarding declaring a property

    - by Simon
    Hi. We declare properties using the @property keyword and synthesize it in the implementation file. My question is, What if I declare a property using the @property keyword and also declare a variable in the interface block with the same name? For example, consider the following code, Interface: @interface myClass : NSObject { NSString *myClass_name; // LINE 1 } @property(nonatomic, retain) NSString *myClass_name; // LINE 2 @end Implementation: @implementation myClass @synthesize myClass_name @end Declaring myClass_name in LINE 1 will make any problem? Like any reference problem or any unnecessary memory consumption problem?

  • UIWebView goBack method acts differently on different devices

    - by maxpower
    First Device: 8gb 2nd gen Version: 3.1.3 (7E18) Model: MB528LL Second Device: 32gb 3rd gen Version: 3.1.3 (7E18) Model: MC008LL When I call goBack on the 8gb device, shouldStartLoadWithRequest:navigationType: is called When I call goBack on the 32gb device, shouldStartLoadWithRequest:navigationType: is not called I am not doing any caching (not like it works anyway). To make sure it wasn't caching I removed any possible caching via the request object's cache policy and removing all cache whenever webViewDidFinishLoading is called. Same app, same url, everything is the same but the device itself. Why? FYI: shouldStartLoadWithRequest:navigationType: is called on the simulator when goBack is called
