  • How to change the size of NSImageView control from within program?

    - by Adam
    The following line of code displays an image on my application window, within an NSImageView control named outputImageView. I used Interface Builder to put the NSImageView control onto the window, initially (then bound it to outputImageView). How do I change the size of the NSImageView control within my program, so that it matches the size of the actual image I am displaying (which may change, periodically)? And what if I wanted to change the anchor point for the image (i.e., centered, left edge, bottom right, or whatever? Thanks in advance! [outputImageView setImage: outputImage];

  • How to get iPhones current orientation?

    - by Mike Rychev
    Is there a special method to get iPhones orientation? I don't need it in degrees or radians, I want it to return an UIInterfaceOrientation object. I just need it for an if-else construction like if(currentOrientation==UIInterfaceOrientationPortrait ||currentOrientation==UIInterfaceOrientationPortraitUpsideDown) { //Code } if (currentOrientation==UIInterfaceOrientationLandscapeRight ||currentOrientation==UIInterfaceOrientationLandscapeLeft ) { //Code } Thanks in advance!

  • Public class: Makes pointer from integer without cast

    - by meridimus
    I have written a class to help save and load data for the sake of persistence for my iPhone application but I have a problem with some NSUIntegers that I'm passing across. Basically, I have the code to use pointers, but eventually it has to start out being an actual value right? So I get this error warning: passing argument 1 of 'getSaveWithCampaign:andLevel:' makes pointer from integer without a cast My code is laid out like so. (Persistence is the name of the class) NSDictionary *saveData = [Persistence getSaveWithCampaign:currentCampaign andLevel:[indexPath row]]; Here's Persistence.m #import "Persistence.h" @implementation Persistence + (NSString *)dataFilePath { NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES); NSString *documentsDirectory = [paths objectAtIndex:0]; return [documentsDirectory stringByAppendingPathComponent:kSaveFilename]; } + (NSDictionary *)getSaveWithCampaign:(NSUInteger *)campaign andLevel:(NSUInteger *)level { NSString *filePath = [self dataFilePath]; if([[NSFileManager defaultManager] fileExistsAtPath:filePath]) { NSDictionary *saveData = [[NSDictionary alloc] initWithContentsOfFile:filePath]; NSString *campaignAndLevelKey = [self makeCampaign:campaign andLevelKey:level]; NSDictionary *campaignAndLevelData = [saveData objectForKey:campaignAndLevelKey]; [saveData release]; return campaignAndLevelData; } else { return nil; } } + (NSString *)makeCampaign:(NSUInteger *)campaign andLevelKey:(NSUInteger *)level { return [[NSString stringWithFormat:@"%d - ", campaign+1] stringByAppendingString:[NSString stringWithFormat:@"%d", level+1]]; } @end

  • What's safe to assume about the NSMutableArray / NSArray class cluster?

    - by andyvn22
    I know you shouldn't use this to decide whether or not to change an array: if ([possiblyMutable isKindOfClass:[NSMutableArray class]]) But say I'm writing a method and need to return either an NSMutableArray or an NSArray, depending on the mutability of possiblyMutable. The class using my method already knows whether or not it's acceptable to change the returned array. Whether or not it's acceptable to change the returned array directly correlates with whether or not it's acceptable to change possiblyMutable. In that specific case, is this code safe? It seems to me that if it's not acceptable to change the array, but we accidentally get a mutable array, it's ok, because the class using my method won't try to change it. And if it is acceptable to change the array, then we will always get possiblyMutable as an NSMutableArray (though this is the part I'm not entirely clear on). So... safe or not? Alternatives?

  • Correct way to clear/release an array of arrays

    - by iFloh
    And again my array of arrays .... When I have an array "x" that contains multiple instances of an array "y", how do I clear/release it without risking memory leaks? are the following calls sufficient? (a) clearing the array [x removeAllObjects]; (b) releasing the array [x release]; or do I need to enumerate the array, such as: (c) clearing the array for(int i=0;i<x.count;i++) [[x objectAtIndex:i] release]; [x removeAllObjects]; (d) releasing the array for(int i=0;i<x.count;i++) [[x objectAtIndex:i] release]; [x release]; thanks in advance

  • App Crashing Inspite of Being ARC Enabled

    - by proctr
    I have been working on an iOS App for sometime now and its almost ready to submit. However, when I gave it to few people for testing purposes (running iOS 5)..they reported cases where the app crashes and the home screen is displayed on the phone OR a frozen app screen appears with no response whatsoever The app is ARC enabled and Xcode shows no warnings. So, I'm relli tensed about what's going wrong. I have declared properties in the following fashion: @property (nonatomic) IBOutlet UILabel *devCountLabel; @property (nonatomic) IBOutlet UIView *splashView; Likewise other properties are declared. Could anyone provide a solution ASAP. It is mainly a network based app and thus, CoreData usage is minimum.. Anyway, I'm running out of time..So Please provide a fix asap..oh and thanks a ton for it. PS: The App doesn't crash in the simulator, so I'm guessing it has something related to memory. And the crashes are random. So, repeating a set of steps to reproduce the crash doesn't help either. For Eg. When I click a button, modalViewControllerAnimation results in normal case. Now this occurs as expected most of the time and freezes the app other times.

  • Access static Method in GDB

    - by Besi
    I recently discovered the GDB in Xcode which makes up for some functionality which IMHO seems to be lacking in Xcode. So I can do the following in GDB: (gdb) po [LoginManager sharedSession].loginToken 20D52FE9-3573-437E-9A65-846572B63726 However, I have another Service class, which is currently not loaded so I get the following error: (gdb) po [SessionService displaySessionInfoForToken:@"XXX"] No symbol "SessionService" in current context. I don't understand why the LoginManager can be loaded but not the SessionService.

  • ios - almost there with updating Core Data

    - by Jeff Kranenburg
    I have been following the answer of this question: How to update existing object in core data? and in the answer it comes across this line of code to update a record within the array: Favorits* favoritsGrabbed = [results objectAtIndex:0]; Now this updates whatever is set a record 0 of the database, no matter what cell I select to edit. I am sorry but I cannot figure out how to change it into updating the cell I have selected. Starting to grow grey hairs here:-) The problem (maybe it is my mindset) is that I am required to give an integer and I am unable to find something to substitute it. Any help would be great.

  • How to take a NSString such as, "0+1+2", get the sum of those and create new string. Obj-C

    - by Ace Legend
    Alright. My app has a text field and next to it are two buttons (Plus button and Equals button). When you press the "Plus" button, it takes the text inside of the textField and adds a "+" to it. Code below: - (IBAction)plusButtonPressed:(id)sender { NSString *plusString = @"+"; NSString *inputString = carbsField.text; NSString *outputString = [NSString stringWithFormat:@"%@%@",inputString,plusString]; NSLog(@"%@",outputString); [carbsField setText:outputString]; } I will eventually make that more intelligent so that I can't put two pluses or whatever. Anyway, then I want the equal button to take whatever is in the textField, which should look something like: "23+54+2.2" and get the sum of those values. I believe I know how to take an Integer and make it a String, but I want to verify it: int *value = 56; NSString *string = @"%d",value; Well, if anyone can show me how to do this, I would be very appreciative. Thanks. EDIT At the moment, I have not tried anything. This is because I do not know where to start. I have an idea of what to do, but I do not know how to execute it. I believe I need to get all characters before a "+" convert them into int and then get the sum of some array of those values.

  • NSTextField enter to trigger action

    - by Chris
    I've been looking all over for a simple example of how to have an action (or button) be triggered when the enter key is hit in the text field. Should I subclass the text field? Would I need to set a delegate to call the action I need? Is there a way to catch the event in my main window controller class? If you could even just point me to the right direction that would be great. Thanks.

  • How do I run modals windows from code with cocoa?

    - by Leandro
    Hi,everybody I`m trying to run a window as modal directly from the code. My program starts and a main NSWindows is showed.A thread still running to see if the user has a valid distribution. if he doesn't I need to run a modal.I mean, I have no buttons clicked in the interface.I've designed a NSWindow on the interface builder for a password set, and I want to call it only when my validation is not successful. I have tested and realized that these methods which are responsible for modal windows running only work in a IBAction environment. //This doesn't work -(void) showPasswordWindow { [NSApp runModalForWindow:[self window]]; } //this works But its not useful for me =( - (IBAction) passwordWindowButton:(id)sender { [NSApp runModalForWindow:[self window]]; } Please, help this newbie =)

  • Passing a column name instead of index in sqlite3

    - by user271753
    The problem code: NSString *query = @"SELECT Name FROM Category"; sqlite3_stmt *statement; if (sqlite3_prepare_v2(database, [query UTF8String], -1, &statement, nil) == SQLITE_OK) { while (sqlite3_step(statement) == SQLITE_ROW) { char *row =(char *)sqlite3_column_text(statement,0); char *rowData = (char *)sqlite3_column_text(statement,1); NSString *fieldName = [[NSString alloc] initWithUTF8String:row]; NSString *fieldValue = [[NSString alloc] initWithUTF8String:rowData]; NSLog(@"%@",fieldName); NSLog(@"%@",fieldValue); [fieldName release]; [fieldValue release]; } sqlite3_finalize(statement); } char *row =(char *)sqlite3_column_text(statement,0); In the above code instead of 0 can't I just pass a column name? How can I do that ?
