  • Exclude some parameters with POST request on RestKit

    - by Mike Meyers
    I've just integrated RestKit with a Mac application for communicating with a web service. After much confusion, I have successfully got requests and responses working using it. The problem I am now finding is that when I want to make a POST request. I have created a RKRequestDescriptor with a mapping for a whole number of properties and all of the properties are being sent as parameters for the query. I want a way of dynamically changing the parameters that are sent, for example not sending some parameters where the property is nil. Is this possible as part of the built-in functionality of RestKit? And if so, how?

  • Setting UIActivityIndicatorView while view is prepared

    - by iFloh
    Hi, I have a UITabbBarController with a UITableView. Under certain circumstances the TabBarControllers dataset requires updating when a user arrives from another view, e.g. the initial load when the TabBarController is called the first time, or when the settings are changed. This dataset update takes about 2 seconds and I want to show an UIActivityIndicatorView. Trouble is that when I enter from another view I don't know which view to attach it to, since the loading of the tabbarController is carried out in the viewWillAppear method. Any clues how I can go about this?

  • Clean bindings with structs

    - by andyvn22
    I have a model class for which it makes quite a lot of sense to have NSSize and NSPoint instance variables. This is lovely. I'm trying to create an editing interface for this object. I'd like to bind to size.width and whatnot. This, of course, doesn't work. What's the cleanest, most Cocoa-y solution to this problem? Of course I could write separate accessors for the individual members of every struct I use, but it seems like there should be a better solution.

  • Make a view to be the primary one in navigation controller?

    - by Earl Grey
    I am using a tabbar, each tab having a navigation controller, and this in turn having a stack of views. Each view is having its own view controller but this is not important now. Lets have a tab 1 with a navigation controller 1 with views A, B, C. The nature of the application dictates however that the view B is the primary one. So what I want is that by default (after first or after relaunch of the app), when I tap the tab 1, I will see the B view together with the back button to A view. How can I achieve this?

  • UIButton custom font vertical alignment

    - by Willshaw Media
    I've got a UIButton which uses a custom font, which is set when my view loads: - (void)viewDidLoad { [super viewDidLoad]; self.searchButton.titleLabel.font = [UIFont fontWithName: @"FONTNAME" size: 15.0 ]; } The problem I've got is that the font is appearing to float up of the center line. If I comment out this line, the default font appears vertically centered fine. But changing to the custom font breaks the vertical alignment. I'm getting the same issue on a Table Cell with a custom font too. Do I need to tell the view somewhere that the custom font is not as tall as other fonts? EDIT: I've just realized that the font I'm using is a Windows TrueType Font. I can use it fine in TextEdit on the Mac, only a problem with the alignment in my App

  • Urban Airship - not receivng push notifications on device?

    - by Silent
    I just installed everything to my app and tried to push, but no messages appear. The token for my device is saved so that's working. When I push, the website says it sent, but no message are received on the device. Right now I'm using a production certificate for push notifications, with a developer provision and not the distribution certificate. I tried cleaning the build and reinstalling but no luck since an extra app was installed from the same one. I used the code that is on the sample file tutorial, I think that's all the details. Don't know what to do next.

  • Retain Count Question: Some Guidance, Please

    - by yar
    [I'm sure this is not odd at all, but I need just a bit of help] I have two retain properties @property (nonatomic, retain) NSArray *listContent; @property (nonatomic, retain) NSArray *filteredListContent; and in the viewDidLoad method I set the second equal to the first (so now the retainCount is two, I think): self.filteredListContent = self.listContent; and then on every search I do this self.filteredListContent = [listContent filteredArrayUsingPredicate:predicate]; I thought I should do a release right above this assignment -- since the property should cause an extra retain, right? -- but that causes the program to explode the second time I run the search method. The retain counts (without the extra release) are 2 the first time I come into the search method, and 1 each subsequent time (which is what I expected, unfortunately). Some guidance would help, thanks! Is it correct to not release?

  • Same code, not the same place, different results

    - by Tom
    Hi! I'm trying to something pretty simple but I don't understand why the second bit of code is giving me a bad access error... First: - (UITableViewCell *)tableView:tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { static NSString *CellIdentifier = @"Cell"; UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier]; if (cell == nil) { cell = [[[UITableViewCell alloc] initWithFrame:CGRectZero reuseIdentifier:CellIdentifier] autorelease]; } // Tom: Converting the row int to a string and adding 1 to it so that the rows fit with the array indexes.) NSString *key = [NSString stringWithFormat:@"%d", indexPath.row+1]; NSArray *array = [self.tableDataSource objectForKey:key]; NSLog(@"%@", key); NSLog(@"%@", [array description]); cell.textLabel.text = [array objectAtIndex:1]; return cell; } That code gives me exactly what I want: 2010-03-18 15:18:12.884 PremierSoins[28005:40b] 1 2010-03-18 15:18:12.885 PremierSoins[28005:40b] ( 7, Blessures ) 2010-03-18 15:18:12.892 PremierSoins[28005:40b] 2 2010-03-18 15:18:12.893 PremierSoins[28005:40b] ( 18, "Test 2" ) But then, the second: - (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath { NSString *key = [NSString stringWithFormat:@"%d", indexPath.row+1]; NSArray *array = [self.tableDataSource objectForKey:key]; NSLog(@"%@", key); NSLog(@"%@", [array description]); } Is only able to get me the key, but the description of the array makes it crash... tableDataSource is a NSMutableDictionary containing multiple arrays... Like this: { 1 = ( 7, Blessures ); 2 = ( 18, "Test 2" ); } Do you have any clue? I've been looking at this since yesterday... Thanks! Tom

  • My view is displaying y=-20 dispite its frame set to y=0. After rotation it snaps back to y=0

    - by jamone
    I started by creating a universal window based app. Starting with the iPhone version I created a UIViewController and associated nib. My App delegate: rootViewController = [[RootViewController alloc] initWithNibName:nil bundle:nil]; [window makeKeyAndVisible]; [window addSubview:rootViewController.view]; return YES; My RootViewController: - (void)viewDidLoad { [super viewDidLoad]; adBannerView = [[ADBannerView alloc] initWithFrame:CGRectZero]; [self.view addSubview:adBannerView]; } I've tried instanciating buttons instead of the adBanner and I get the same result. My RootViewController's nib has not been changed since x-code created it for me. My MainWindow_iPhone.xib also is stock. What's causing this?

  • ObjC get property name

    - by Joe Even
    Yes. I've searched a lot without success. I've looking for a way to get a property name as StringValue from inside a method. Lets say: My class has X Subviews from the Type UILabel. @property (strong, nonatomic) UILabel *firstLabel; @property (strong, nonatomic) UILabel *secondLabel; [...] and so on. Inside the method foo, the views are iterated as followed: -(void) foo { for (UIView *view in self.subviews) { if( [view isKindOfClass:[UILabel class]] ) { /* codeblock that gets the property name. */ } } } The Result should be something like that: THE propertyName(NSString) OF view(UILabel) IS "firstLabel" I've tried class_getInstanceVariable, object_getIvar and property_getName without Success. For Example, the Code for: [...] property_getName((void*)&view) [...] RETURNS: <UILabel: 0x6b768c0; frame = (65 375; 219 21); text = 'Something'; clipsToBounds = YES; opaque = NO; autoresize = RM+BM; userInteractionEnabled = NO; layer = <CALayer: 0x6b76930>> But i'm looking for this kind of result: "firstLabel" , "secondLabel" and so on. Thanks for your help! Reagrds Joé

  • How to access the CGColor property of UIColor in CGContextSetFillColorWithColor?

    - by Azeworai
    CGContextSetFillColorWithColor(g, [UIColor greyColor].CGColor); I'm trying to follow O'Reilly's iPhone Game Development book on page 73 Chapter 3 but I'm running into a compile error that states error: request for member 'CGColor' in something not a structure or union According to the book's errata page this is an unconfirmed errata in the book. I'm hoping that someone could help me replace that line of code to something that works. The example project can be downloaded from sourceforge at this link.

  • Increasing width of UISearchDisplayController PopOver Results

    - by George
    I have an iPad app that has a UISearchBar in its navigation bar. When I enter text in the search bar the results are automatically displayed in a UIPopOverController. That's great except the popover's default size is not wide enough for my needs. Is there a way to set its width? Apple has done this themselves with Safari's search bar. The popover that displays search results is a good bit wider than the default and they have removed the "Results" title from the popover.

  • UIWebView in multithread ViewController

    - by Tao
    I have a UIWebView in a viewcontroller, which has two methods as below. The question is if I pop out(tap back on navigation bar) this controller before the second thread is done, the app will crash after [super dealloc], because "Tried to obtain the web lock from a thread other than the main thread or the web thread. This may be a result of calling to UIKit from a secondary thread.". Any help would be really appreciated. -(void)viewDidAppear:(BOOL)animated { [super viewWillAppear:animated]; NSInvocationOperation *operation = [[NSInvocationOperation alloc] initWithTarget:self selector:@selector(load) object:nil]; [operationQueue addOperation:operation]; [operation release]; } -(void)load { [NSThread sleepForTimeInterval:5]; [self performSelectorOnMainThread:@selector(done) withObject:nil waitUntilDone:NO]; }

  • Programatically get own Phone Number in iPhone OS 4.0

    - by sandy
    I am developing an iPhone application for jail broken phones and in this application I would like to fetch user's phone number. I have gone through the entire stackoverflow.com and found some relevant answers but all of them are obsolete and doesn't work with iOS 4.0 anymore. The most famous solution for this problem is NSString *num = [[NSUserDefaults standardUserDefaults] stringForKey:@"SBFormattedPhoneNumber"]; but as I mentioned this solution no more works with iOS 4.0 As my application is intended towards the jail broken phones and not intended the Apple app store so I am not worried about my app rejection, hence any private API will also work for me. Also please let me know if we can fetch IMSI number from SIM using any private APIs of iPhone

  • iphone simulator crashes when it tries to access user location

    - by kevin Mendoza
    for some reason my code causes my program to crash. does anyone know why or how to fix it? NSLog(@"here"); CLLocation *location = [locationManager location]; [mapView removeAnnotations:mapView.annotations]; NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults]; CLLocationCoordinate2D workingCoordinate = [location coordinate]; NSLog(@" this is %@", workingCoordinate.latitude); it makes it to the first NSLog, but somewhere between the first and second it crashes. My guess is that it has to do with the CLLocation *location line.

  • Background color remaining when switching views

    - by Guy
    Hi Guys. I have a UIViewController named equationVC who's user interface is being programmatically created from another NSObject class called equationCon. Upon loading equationVC, a method called chooseInterface is called from the equationCon class. I have a global variable (globalVar) that points to a user defined string. chooseInterface finds a method in the equationCon class that matches the string globalVar points to. In this case, let's say that globalVar points to a string that is called "methodThatMatches." In methodThatMatches, another view controller needs to show the results of what methodThatMatches did. methodThatMatches creates a new equationVC that calls upon methodThatMatches2. As a test, each method changes the color of the background. When the application starts up, I get a purple background, but as soon as I hit backwards I get another purple screen, which should be yellow. I do not think that I am release the view properly. Can anyone help? -(void)chooseInterface { NSString* equationTemp = [globalVar stringByReplacingOccurrencesOfString:@" " withString:@""]; equationTemp = [equationTemp stringByReplacingOccurrencesOfString:@"'" withString:@""]; SEL equationName = NSSelectorFromString(equationTemp); NSLog(@"selector! %@",NSStringFromSelector(equationName)); if([self respondsToSelector:equationName]){ [self performSelector:equationName]; } } -(void)methodThatMatches{ self.equationVC.view.backgroundColor = [UIColor yellowColor]; [setGlobalVar:@"methodThatMatches2"]; EquationVC* temp = [[EquationVC alloc] init]; [[self.equationVC navigationController] pushViewController:temp animated:YES ]; [temp release]; } -(void)methodThatmatches2{ self.equationVC.view.backgroundColor = [UIColor purpleColor]; }

  • Loading...Please wait for UIWebView - iPhone

    - by niha7229
    Hi guys, In Safari and other browsers, there is a bar that would indicate the percentage of the loading progress, and I, myself, trying to implement something similiar on iPhone, when loading some content in UIWebView, I would like the app to indicate the percentage of the page being loaded. I tried some google search and realize we could use NSURLConnection to read only the header and get the Content-Length ( but don't know how to, I read the Apple's NSURLConnection docs but probably I missed something ... ). And the size ( kb ) which UIWebView had loaded, seem like UIWebView don't support it for the public API... I hope this would be complete in some other ways than I thought, so if you have any ideas, please throw it out, thanks for your patient reading. P.S : I could just show an Activities Indicator for users with the long loading progress actions of the UIWebView but I just want to go further with the loading percentage bar :). Regards.
