  • How can I fix this NavigationController and UIToolbar offset issue in Objective-C?

    - by editor
    I'm adding a couple of buttons to an already-existing NavigationController. The two buttons are added to a UIView, which is pushed onto the NavigationItem. The buttons stop and reload a UIWebView. Problem is that there's a slight offset issue that is making it all look pretty ugly. I wish I could set the UIToolbar to transparent or clear background but that doesn't seem to be an option. Can't seem to use negative offsets either. I've got color matching, but if you look closely there's 1px or 2px of highlighting up top that's causing a visual mismatch and then a slight offset at the bottom. Some relevant code below (based on this, inbound Googlers). What are my options to resolve this? // create a toolbar for the buttons UIToolbar* toolbar = [[UIToolbar alloc] initWithFrame:CGRectMake(0, 0, 100, 45)]; [toolbar setBarStyle: UIBarStyleDefault]; UIColor *colorForBar = [[UIColor alloc] initWithRed:.72 green:0 blue:0 alpha:0]; toolbar.tintColor = colorForBar; [colorForBar release]; //[toolbar setTranslucent:YES]; // create an array for the buttons NSMutableArray* buttons = [[NSMutableArray alloc] initWithCapacity:3]; // create a standard reload button UIBarButtonItem *reloadButton = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemRefresh target:self action:@selector(reload)]; reloadButton.style = UIBarButtonItemStyleBordered; [buttons addObject:reloadButton]; [reloadButton release]; // create a spacer between the buttons UIBarButtonItem *spacer = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemFixedSpace target:nil action:nil]; [buttons addObject:spacer]; [spacer release]; // create a standard delete button with the trash icon UIBarButtonItem *stopButton = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemStop target:self action:@selector(stopLoading)]; stopButton.style = UIBarButtonItemStyleBordered; [buttons addObject:stopButton]; [stopButton release]; // put the buttons in the toolbar and release them [toolbar setItems:buttons animated:NO]; [buttons release]; // place the toolbar into the navigation bar self.navigationItem.rightBarButtonItem = [[UIBarButtonItem alloc] initWithCustomView:toolbar]; [toolbar release];

  • Automatically Loading XIB for UITableViewController

    - by ACBurk
    Ran into something interesting, want to know if I'm doing something wrong or if this is the correct behavior. I have a custom UITableViewController. I ASSUMED (first mistake) that if you initialize as such: [[CustomTableController alloc] init]; it would automatically load from a XIB of the same name, CustomTableController.xib, if it is in the same directory and such. HOWEVER This does not work; doesn't load the XIB. BUT, if I change the parent class of my controller from 'UITableViewController' to 'UIViewController', EVERYHTING WORKS FINE! Calling: [[CustomTableController alloc] init]; loads the controller and view from my xib. Am I doing something wrong? Is this a bug? Expected behavior?

  • In Cocoa, why won't a textfield be shown until after the IBAction is completely executed?

    - by Nano8Blazex
    I have an IBAction with some simple code inside: -(IBAction)change:(id)sender { [textfield setHidden:NO]; [self dolengthyaction]; } 'textfield' is an NSTextField in a nib file, and -'dolengthyaction' is a function that takes about a minute to finish executing. My question is: Why isn't the textfield shown until AFTER "dolengthyaction" is done executing? I want it to be revealed before the dolengthyaction starts taking place. Is this an inherent problem or is there something wrong with my code? (or in another part of my code?) I'm still not very good at programming so I apologize if I worded something badly and formatted something wrong.

  • UIView, UIScrollView and UITextFields problem calling Method

    - by Jeff Groby
    I have a view with several embedded UITextFields, this UIView is subordinated to a UIScrollView in IB. Each text field is supposed to invoke a method called updateText defined in the viewcontroller implementation file when the user is done editing the field. For some reason, the method updateText never gets invoked. Anyone have any ideas how to go about fixing this? The method fired off just fine when the UIScrollView was not present in the project but the keyboard would cover the text fields during input, which was annoying. Now my textfields move up above the keyboard when it appears, but won't fire off the method when done editing. Here is my implementation file: #import "MileMarkerViewController.h" @implementation MileMarkerViewController @synthesize scrollView,milemarkerLogDate,milemarkerDesc,milemarkerOdobeg,milemarkerOdoend,milemarkerBusiness,milemarkerPersonal,milemarker; - (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil { if (self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil]) { // Initialization code } return self; } - (BOOL) textFieldShouldReturn: (UITextField*) theTextField { return [theTextField resignFirstResponder]; } - (void)viewDidLoad { [super viewDidLoad]; [[NSNotificationCenter defaultCenter] addObserver: self selector: @selector(keyboardWasShown:) name: UIKeyboardDidShowNotification object: nil]; [[NSNotificationCenter defaultCenter] addObserver: self selector: @selector(keyboardWasHidden:) name: UIKeyboardDidHideNotification object: nil]; keyboardShown = NO; // 1 [scrollView setContentSize: CGSizeMake( 320, 480)]; // 2 } - (void)keyboardWasShown:(NSNotification*)aNotification { if (keyboardShown) return; NSDictionary* info = [aNotification userInfo]; // Get the size of the keyboard. NSValue* aValue = [info objectForKey:UIKeyboardBoundsUserInfoKey]; CGSize keyboardSize = [aValue CGRectValue].size; // Resize the scroll view (which is the root view of the window) CGRect viewFrame = [scrollView frame]; viewFrame.size.height -= keyboardSize.height; scrollView.frame = viewFrame; // Scroll the active text field into view. CGRect textFieldRect = [activeField frame]; [scrollView scrollRectToVisible:textFieldRect animated:YES]; keyboardShown = YES; } - (void)keyboardWasHidden:(NSNotification*)aNotification { NSDictionary* info = [aNotification userInfo]; // Get the size of the keyboard. NSValue* aValue = [info objectForKey:UIKeyboardBoundsUserInfoKey]; CGSize keyboardSize = [aValue CGRectValue].size; // Reset the height of the scroll view to its original value CGRect viewFrame = [scrollView frame]; viewFrame.size.height += keyboardSize.height; [scrollView scrollRectToVisible:CGRectMake(0, 0, 1, 1) animated:YES]; scrollView.frame = viewFrame; keyboardShown = NO; } - (void)textFieldDidBeginEditing:(UITextField *)textField { activeField = textField; } - (void)textFieldDidEndEditing:(UITextField *)textField { activeField = nil; } - (IBAction)updateText:(id) sender { NSLog(@"You just entered: %@",self.milemarkerLogDate.text); self.milemarker.logdate = self.milemarkerLogDate.text; self.milemarker.desc = self.milemarkerDesc.text; self.milemarker.odobeg = self.milemarkerOdobeg.text; self.milemarker.odoend = self.milemarkerOdoend.text; self.milemarker.business = self.milemarkerBusiness.text; self.milemarker.personal = self.milemarkerPersonal.text; NSLog(@"Original textfield is set to: %@",self.milemarker.logdate); [self.milemarker updateText]; } - (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)dealloc { [super dealloc]; } @end

  • Customize iPhone view for iPad

    - by Erick Sasse
    I have converted a very simple iPhone app to Universal app. Now I need to customize the view on the iPad to use a higher resolution image for the background, move and resize some labels, etc. How can I do it without changing the iPhone version? I can see that there is a new MainWindow-iPad.xib, but when I open in IB, it looks empty. Thanks.

  • iPhone application lifecycle

    - by iter
    InterfaceBuilder generates this method for me in fooAppDelegate.m: - (void)applicationDidFinishLaunching:(UIApplication *)application { // Override point for customization after app launch [window addSubview:[navigationController view]]; [window makeKeyAndVisible]; } IB also puts UIWindow *window; in fooAppDelegate.h and @synthesize window; in fooAppDelegate.m, and correspondingly for navigationController. IB generates code to release window and navigationController in dealloc. I cannot see any code that allocates and initializes the window and the navigationController. I wonder where that happens. Ari.

  • Capturing USB Plug/Unplug events in Firemonkey

    - by radsdau
    [RAD Studio XE3 / C++] I have a FMX project running in Windows only at this stage, but I need to detect events when USB devices are connected and disconnected. I have a similar VCL app that can do this fine, but the Application-HookMainWindow is not exposed in FMX (only VCL). Is there an elegant way to handle this? Or do I have to hack some VCL stuff into my FMX app to make that work? I'd imagine I have to abstract it so I can support other platforms down the track. For the meantime though I need to get the Windows solution working. If the 'VCL hack' thing is required, how would I reference the vcl::Forms::Application from within my Fmx app? Cheers.

  • Views jump during ViewDidLoad

    - by Jon-Paul
    Hi, I have a custom button, subclassed from UIButton that is initialised as below (obviously all the button does is use a custom font). @implementation HWButton - (id)initWithCoder:(NSCoder *)decoder { if (self = [super initWithCoder: decoder]) { [self.titleLabel setFont:[UIFont fontWithName: @"eraserdust" size: self.titleLabel.font.pointSize]]; } return self; } So far so good. But when I use the custom class in my nib and launch the app, the button initially displays for a split second as tiny with small text, then grows. So the outcome is what I want, but I don't want to see the transition. Can anyone put me right? Thanks. JP

  • How can I make a view start in landscape?

    - by Alex Gosselin
    I have read a few questions about an app doing it through the info file but not a certain view. I just need the interface to be set up to start in landscape view. I managed to get near what I want with shouldAutoRotateToInterfaceOrientation:, but it only works after I rotate the view. I am kinda new to the documentation on this so I may be looking in the wrong places for this. Any help is appreciated.

  • One IBOutlet for two UILabels

    - by Mike Rychev
    I have two views within one .xib (one view for landscape, another for portrait). How can I use the same IBOutlet I've defined in @interface section for both labels if they have the same functionality. (ctrl+dragging to both of them does'n help-each time I drag to second, the first one loses its outlet).

  • Iphone sdk - please help , 1 view takes me 45 minutes to do :(

    - by Dave
    Hey, I've been working on a Cook Book App but each view ( or recipie page) takes about 45 minutes to complete so as you can imagine its taking forever. The problem is that I have to manually: Set up a gradient image for the back ground (Somtimes I have to add a few image backgrounds to fit the view as I often use a scroll view, not sure how this could be automated?) Put an image behind the titles "Recipe name" , "Time needed" and an image to go behind the recipie instructions ( again I might need a few of these depending on how long the description is. Creating view controllers for main sections such as "Breakfast" and "Lunch" and then I need to manually create view controllers to go in these sections. Theres got to be a way to set up a template for this? Thanks for reading all of this.

  • BWToolkit inclusion crashing

    - by Schroedinger
    Hey guys I'm using the latest version of XCode (3.2.2) and I've linked the framework using the tutorial. I was building my app and tested it and I get a BWToolkit exception on decoding. I've included the Framework in the frameworks and added it to the copy files stage. I even created a new dummy app including the framework and adding it to the copy files stage and it still crashes when I try to run. Any ideas? Do I need to include it somewhere in the app? I'm worried I've overlooked something really simple. 2010-04-13 14:14:24.540 BWTestFramework[7504:a0f] An uncaught exception was raised 2010-04-13 14:14:24.543 BWTestFramework[7504:a0f] *** -[NSKeyedUnarchiver decodeObjectForKey:]: cannot decode object of class (BWSplitView) 2010-04-13 14:14:24.545 BWTestFramework[7504:a0f] *** Terminating app due to uncaught exception 'NSInvalidUnarchiveOperationException', reason: '*** -[NSKeyedUnarchiver decodeObjectForKey:]: cannot decode object of class (BWSplitView)' *** Call stack at first throw: ( 0 CoreFoundation 0x00007fff84a77d24 __exceptionPreprocess + 180 1 libobjc.A.dylib 0x00007fff82ba00f3 objc_exception_throw + 45 2 CoreFoundation 0x00007fff84a77b47 +[NSException raise:format:arguments:] + 103 3 CoreFoundation 0x00007fff84a77ad4 +[NSException raise:format:] + 148 4 Foundation 0x00007fff83804aa6 _decodeObjectBinary + 2427 5 Foundation 0x00007fff83805825 -[NSKeyedUnarchiver _decodeArrayOfObjectsForKey:] + 1229 6 Foundation 0x00007fff83805d65 -[NSArray(NSArray) initWithCoder:] + 462 7 Foundation 0x00007fff83804b1f _decodeObjectBinary + 2548 8 Foundation 0x00007fff83803f99 _decodeObject + 208 9 AppKit 0x00007fff8069fbfb -[NSView initWithCoder:] + 362 10 Foundation 0x00007fff83804b1f _decodeObjectBinary + 2548 11 Foundation 0x00007fff83803f99 _decodeObject + 208 12 AppKit 0x00007fff806adfbb -[NSWindowTemplate initWithCoder:] + 3824 13 Foundation 0x00007fff83804b1f _decodeObjectBinary + 2548 14 Foundation 0x00007fff83805825 -[NSKeyedUnarchiver _decodeArrayOfObjectsForKey:] + 1229 15 Foundation 0x00007fff83805268 -[NSSet(NSSet) initWithCoder:] + 447 16 Foundation 0x00007fff83804b1f _decodeObjectBinary + 2548 17 Foundation 0x00007fff83803f99 _decodeObject + 208 18 AppKit 0x00007fff8062fcde -[NSIBObjectData initWithCoder:] + 1983 19 Foundation 0x00007fff83804b1f _decodeObjectBinary + 2548 20 Foundation 0x00007fff83803f99 _decodeObject + 208 21 AppKit 0x00007fff8062f40d loadNib + 146 22 AppKit 0x00007fff8062e96d +[NSBundle(NSNibLoading) _loadNibFile:nameTable:withZone:ownerBundle:] + 248 23 AppKit 0x00007fff8062e7a5 +[NSBundle(NSNibLoading) loadNibNamed:owner:] + 326 24 AppKit 0x00007fff8062bd27 NSApplicationMain + 279 25 BWTestFramework 0x0000000100001891 main + 33 26 BWTestFramework 0x0000000100001868 start + 52 ) terminate called after throwing an instance of 'NSException' That's the crash report

  • Flex4 Application state in a custom component

    - by itarato
    Hi, I'm porting my Flex3 app to Flex4 (FlashBuilder4). I get the whole new state concept, except one thing. In a custom component (separate mxml file) I'm using the main level Application's state. In Flex3 it was: <mx:State name="only_view_mode"> <mx:RemoveChild target="{myComponent.button1}" /> </mx:State> In Flex4 it should be something like that: <mx:State name="only_view_mode" /> and <mx:LinkButton id="button1" excludeFrom="???" /> My question is: how can I access to an Application state from a component? I checked the official reference (http://www.adobe.com/go/learn_flex4_alldocumentation_en) and Google of course but without any success. Thanks in advance

  • ViewController vs. View

    - by James
    Trying to wrap my head around the apple design scheme. I have a UIViewController and the corresponding XIB file that has my main screen in my application. I want to have a button on this XIB that displays another "form" (this is my disconnect) in the foreground where the user selects from a myriad of choices, then it hides that "form" and goes back to the first one. I'm completely lost here. Initially I thought I'd just add another view and set the self.view of my controller to the new view, add another IBAction and call it a day, but I can't seem to make that work. For sake of argument, say I want to "gray out" the current form, have a modal type window that takes up roughly 60% of the screen and requires you select an option, then it hides itself and we go back to normal. What is the standard approach here? Thanks

  • How to convert nib/xib to objective C code?

    - by Mickey Shine
    I am just wondering is there a way to convert nib/xib file to ojbective C code? I just want to find the equivalent code to the nib/xib file (I've tried nib2objc, seems the result is not what I am after). Actually I want to compile this example http://developer.apple.com/iphone/library/samplecode/TableSearch/index.html without nib/xib file (I want it exactly the same with original), any idea about doing this?

  • Puzzled with nib files...

    - by Michael
    I know nib files are serialized objects and they have owner, outlets to make connections. Using XCode Navigation window template I created application, which in its order created 2 nib files - MainWindow and SecondView. I can't understand how MainWindow is referring to SecondView, there is no connection between those two as far as I can see. SecondView's owner is UIViewController and in MainWindow there is a navigation tab which is also UIViewController. But how they are connected in IB I can't understand... Also I don't understand who is instanciating MainWindow's owner object and where that object is being kept, where is the variable which is UIApplication myApp = [[UIApplication alloc] init]. If I create 10 nib files with UIViewController owner, who will trigger their deserialization? If some class is nib file's owner, what is the essential responsibilities of that class? Is it deserializing nib file into memory? Sorry for unorganized questions, I've been reading numerous articles and docs about nib files, but it is still confusing.
