  • Performance issue finding weekdays over a given period

    - by Oysio
    I have some methods that return the number of weekdays between two given dates. Since calling these methods become very expensive to call when the two dates lie years apart, I'm wondering how these methods could be refactored in a more efficient way. The returned result is correct but I feel that the iphone processor is struggling to keep up and consequently freezes up the application when I would call these methods over a period of say 10years. Any suggestions ? //daysList contains all weekdays that need to be found between the two dates -(NSInteger) numberOfWeekdaysFromDaysList:(NSMutableArray*) daysList startingFromDate:(NSDate*)startDate toDate:(NSDate*)endDate { NSInteger retNumdays = 0; for (Day *dayObject in [daysList objectEnumerator]) { if ([dayObject isChecked]) { retNumdays += [self numberOfWeekday:[dayObject weekdayNr] startingFromDate:startDate toDate:endDate]; } } return retNumdays; } -(NSInteger) numberOfWeekday:(NSInteger)day startingFromDate:(NSDate*)startDate toDate:(NSDate*)endDate { NSInteger numWeekdays = 0; NSDate *nextDate = startDate; NSComparisonResult result = [endDate compare:nextDate]; //Do while nextDate is in the past while (result == NSOrderedDescending || result == NSOrderedSame) { if ([NSDate weekdayFromDate:nextDate] == day) { numWeekdays++; } nextDate = [nextDate dateByAddingDays:1]; result = [endDate compare:nextDate]; } return numWeekdays; }

  • Is there a difference between NSString compare: and isEqual(ToString): ?

    - by frenetisch applaudierend
    Occasionally I find code which tests if two NSStrings are the same like this: if ([str1 compare:str2] == NSOrderedSame) { // Do something } Now, I believe this is less readable than using isEqualToString: and it also has some nasty side effects, like if str1 == nil the if(..) evaluates to true, or when str2 == nil havoc might break upon us according to the Apple docs. But before I crusade against those statements in my companys code, I wanted to make sure I didn't miss some important point. So my question basically boils down to: Is there any difference between a compare: to NSOrderedSame and isEqual:?

  • Disable the Go button in the Keyboard for a UITextfield in iphone app.

    - by coder net
    Hi, My app has a screen where keyboard is always visible. The main element of the screen is a UITextfield. For easy data entering, keyboard is always made visible. When the user finishes entering data and hits Go, the app performs a 4,5 seconds action which is done in the background thread in order to show UIActivityIndicatorView. My problem is that the Go button on the keyboard still shows as enabled since the logic is performed in the background. The user could potentially hit the Go again causing it to run again. I am not able to set editable/userinteraction properties to No because then the keyboard disappears. Is there anyway just to disable the Go button or freeze the keyboard until the background thread returns?

  • Drop down view in cocoa

    - by coffeebean
    I'm looking to create a 'drop down' view that falls in front of the main window. An example of this would be the window that drops down when you click 'Advanced' in System Preferences-Networking. If someone could point me in the right direction documentation-wise that would be great. Thanks in advance.

  • UIView to Form Sheet flip animation rotation issue

    - by GSD
    I have this view to form sheet flip animation that works great in portrait mode but not in any other orientations. In my code, I use it with a UIView embedded in another UIView, which is in the root view. The animation will be rotated. Anyone has an idea why? - (void)presentModalViewControllerWithFlipAnimation:(UIViewController *)modalViewController fromView:(UIView *)fromView { UIWindow* window = [[UIApplication sharedApplication] windows][0]; _fromViewSnapshot = [[UIImageView alloc] initWithFrame:fromView.bounds]; UIGraphicsBeginImageContext(fromView.bounds.size); [fromView.layer renderInContext:UIGraphicsGetCurrentContext()]; [_fromViewSnapshot setImage:UIGraphicsGetImageFromCurrentImageContext()]; [_fromViewSnapshot sizeToFit]; UIGraphicsEndImageContext(); _fromViewSnapshot.autoresizesSubviews = YES; _fromViewSnapshot.frame = [fromView.superview convertRect:fromView.frame toView:window]; [window addSubview:_fromViewSnapshot]; fromView.hidden = YES; modalViewController.modalPresentationStyle = UIModalPresentationFormSheet; [self presentViewController:modalViewController animated:NO completion:nil]; UIView __weak *presentedView = modalViewController.view.superview; UIGraphicsBeginImageContext(presentedView.bounds.size); [presentedView.layer renderInContext:UIGraphicsGetCurrentContext()]; UIImage* modalSnapshot = UIGraphicsGetImageFromCurrentImageContext(); UIGraphicsEndImageContext(); UIView __weak *presentationSuperview = presentedView.superview; [presentedView removeFromSuperview]; UIImageView* presentationSnapshotView = [[UIImageView alloc] initWithImage:modalSnapshot]; presentationSnapshotView.autoresizingMask = UIViewAutoresizingNone; [_fromViewSnapshot.superview bringSubviewToFront:_fromViewSnapshot]; [UIView animateWithDuration:kFlipAnimationScaleSpeed delay:0 options:UIViewAnimationOptionCurveEaseIn|UIViewAnimationOptionBeginFromCurrentState animations: ^{ [UIView animateWithDuration:kFlipAnimationScaleSpeed delay:0 options:UIViewAnimationOptionBeginFromCurrentState animations: ^{ _fromViewSnapshot.frame = [_fromViewSnapshot.superview convertRect:presentedView.frame fromView:presentationSuperview]; } completion:nil]; } completion:^(BOOL finished) { [UIView setAnimationBeginsFromCurrentState:YES]; [UIView transitionWithView:_fromViewSnapshot duration:kFlipAnimationSpeed options:UIViewAnimationOptionCurveEaseIn|UIViewAnimationOptionTransitionFlipFromRight animations: ^{ presentationSnapshotView.frame = _fromViewSnapshot.bounds; [_fromViewSnapshot addSubview:presentationSnapshotView]; } completion:^(BOOL finished) { [presentationSuperview addSubview:presentedView]; [presentationSnapshotView removeFromSuperview]; [_fromViewSnapshot removeFromSuperview]; }]; }]; } - (void)dismissViewControllerWithFlipAnimation:(UIView*)fromView completion:(void (^)(void))completion { UIWindow* window = [[UIApplication sharedApplication] windows][0]; UIView __weak *presentedView = self.presentedViewController.view.superview; UIGraphicsBeginImageContext(presentedView.bounds.size); [presentedView.layer renderInContext:UIGraphicsGetCurrentContext()]; UIImage* modalSnapshot = UIGraphicsGetImageFromCurrentImageContext(); UIGraphicsEndImageContext(); [presentedView removeFromSuperview]; UIImageView* presentationSnapshotView = [[UIImageView alloc] initWithImage:modalSnapshot]; presentationSnapshotView.autoresizingMask = UIViewAutoresizingNone; presentationSnapshotView.frame = presentedView.frame; [window addSubview:presentationSnapshotView]; [UIView animateWithDuration:kFlipAnimationScaleSpeed delay:0 options:UIViewAnimationOptionCurveEaseIn|UIViewAnimationOptionBeginFromCurrentState animations: ^{ [UIView animateWithDuration:kFlipAnimationScaleSpeed delay:0 options:UIViewAnimationOptionBeginFromCurrentState animations: ^{ presentationSnapshotView.frame = [fromView.superview convertRect:fromView.frame toView:window]; } completion:nil]; } completion:^(BOOL finished) { [UIView setAnimationBeginsFromCurrentState:YES]; [UIView transitionWithView:presentationSnapshotView duration:kFlipAnimationSpeed options:UIViewAnimationOptionCurveEaseIn|UIViewAnimationOptionTransitionFlipFromLeft animations: ^{ _fromViewSnapshot.frame = presentationSnapshotView.bounds; [presentationSnapshotView setImage:[(UIImageView*)_fromViewSnapshot image]]; [self dismissViewControllerAnimated:NO completion:nil]; } completion:^(BOOL finished) { [presentationSnapshotView removeFromSuperview]; _fromViewSnapshot = nil; completion(); }]; }]; }

  • iphone memory management: alloc and retain properties.

    - by Jonathan
    According to the docs, you do one release per alloc or retain (etc) However what about when using retain propertys? eg: HEADER @property(retain)UIView *someView; IMPLEMENTATION /*in some method*/ UIView *tempView = [[UIView alloc] init]; //<<<<<ALLOC - retain count = +1 [tempView setBackgroundColor:[UIColor redColor]]; self.someView = tempView; ///<<<<<RETAIN - retain count = +2 [tempView release]; ///should I do this? or a different version of the IMPLEMENTATION self.someView = [[UIView alloc] init]; //<<<<<ALLOC & RETAIN - retain count = +2 //now what??? [self.someView release]; ???? EDIT: I didn't make it clear, but I meant what to do in both circumstances, not just the first.

  • COCOA: Programatically creating new windows and accessing window objects

    - by Jeffrey Kern
    I'm having an issue with creating new windows in Cocoa. Hypothetically speaking, lets say I have "WindowA" and has a button called "myButton". When you click on "myButton", it runs this code in the following class file: -(void)openFile2:(id)sender { myNextWindow = [[TestWindowController alloc] initWithWindowNibName:@"MainMenu"]; NSString *testString = @"foo"; [myNextWindow showWindow:self]; [myNextWindow setButtonText:testString]; } The code in a nutshell makes a duplicate "WindowA" and shows it. As you can see, this code also runs a method called 'setButtonText', which is this: - (void)setButtonText:(NSString *)passedText { [myButton setTitle:passedText]; } The problem is that when I call this method locally, in the original window - the button text changes (e.g., [self setButtonText:testString]) it works. However, it does not work in the newly created window (e.g., [myNextWindow setButtonText:testString];) When I debug the newly created window, step by step, the 'myButton' value it gives is 0x0. Do I have to manually assign controllers/delegates to the new window? I think the 'myButton' in the code isn't associated to the 'myButton' in the newly created window. How would I fix this problem?

  • UIWebView autosize issue only on iOS 4.3

    - by troop231
    I am trying to figure out how to fix this bug that only occurs on iOS 4.3. When the application launches, it displays a PDF that is scaled to fit in the UIWebView. It behaves perfectly until you pinch to zoom on the document, and then rotate it, leaving behind a black area. If you don't pinch to zoom, it doesn't leave the black area. I don't understand why this is a iOS 4.3 only issue. Screenshot of the issue: I've been trying to solve this problem awhile now, and would greatly appreciate your help. Thank you. Screenshots of the .xib settings: The code I'm using is: .h: #import <UIKit/UIKit.h> @interface ViewController : UIViewController { UIWebView *webView; } @property (nonatomic) IBOutlet UIWebView *webView; @end .m: #import "ViewController.h" @interface ViewController () @end @implementation ViewController @synthesize webView; - (BOOL)shouldAutorotateToInterfaceOrientation: (UIInterfaceOrientation)interfaceOrientation { if (UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPad) { return YES; } else { return (interfaceOrientation != UIInterfaceOrientationPortraitUpsideDown); } } - (void)viewDidLoad { [super viewDidLoad]; NSString *urlAddress = [[NSBundle mainBundle] pathForResource:@"test" ofType:@"pdf"]; NSURL *url = [NSURL fileURLWithPath:urlAddress]; NSURLRequest *requestObj = [NSURLRequest requestWithURL:url]; [webView loadRequest:requestObj]; } - (void)didReceiveMemoryWarning { [super didReceiveMemoryWarning]; } @end
