  • Trouble in type casting or any ideas ???

    - by ahmet732
    I write code below but it gives warning.. I identified dbdesc as a NSString but nothing changes.. How will I handle with this type of warnings? **[self.searchDetailViewController setText:appDelegate.dbdesc];** warning:'searchDetailViewController' may not respond to 'setText:' (Messages without a message method signatures will be assumed to return (id) and accept '...'as arguments )

  • Replace an Array with an Array

    - by Dane Man
    I have and NSMutableArray and I want to replace it with another, but if I try to do it like this... firstArray = secondArray; ...then it seems to erase the entire firstArray and I get this error message.. Terminating app due to uncaught exception 'NSRangeException', reason: '*** -[NSCFArray objectAtIndex:]: index (0) beyond bounds (0)' ...and the bounds should be (6) not (0). Is there a correct way to replace the array? PS: I already checked the secondArray and it functions fine.

  • Recording custom overlay on iPhone

    Hi all, I'm interested in recording a video with a custom overlay which would end up in the video itself. They could be UIImage or even better, an OpenGL viewport, is there even such possibility right now on any iPhone devices/SDK ? Thanks

  • Accessing Amazon E-Commerce Services through Cocoa Touch

    - by Gregory Hill
    Has anyone successfully accessed AWS (Amazon E-Commerce Services) through Cocoa Touch? I've been digging around, and haven't seen the issue addressed directly. I've created an AWS account, and have seen some sample code for accessing web services through Cocoa, but I'm not quite sure how to tie it all together. If anyone has any sample code, I'd love to see it. I'm just trying to get my head around the concepts.

  • Change the contents of a UITableView via a swipe?

    - by Mark
    Im currently using a UITableView like any other, and I am researching into the ability to perform a swipe gesture on the screen, which will then shift the contents of the visible table over to display new content for example: swiping right-to-left on the screen would change (via animation) the contents within each of the cells on screen to show new data. What I can do is detect a swipe on the cells, or perhaps on the UITableViewController, but what I dont know how to do two fold: 1) Change data in all cells (could you have a set of hidden views within a custom table cell that animate in and out of each cell per swipe?) 2) How can you do this to all cells? Thanks a lot Mark

  • Optimizing NSNumber numberWithInt:

    - by Riviera
    I am profiling an iPhone app and I noticed a strange pattern. In a certain block of code that's called quite frequently... [item setQuadrant:[NSNumber numberWithInt:a]]; [item setIndex:[NSNumber numberWithInt:b]]; [item setTimestamp:[NSNumber numberWithInt:c]]; [item setState:[NSNumber numberWithInt:d]]; [item setCompletionPercentage:[NSNumber numberWithInt:e]]; [item setId_:[NSNumber numberWithInt:f]]; ...the first call to [NSNumber numberWithInt:] takes an inordinate amount of time, in the order of 10-15x that of the remaining calls. I've verified that the results are consistent if I shuffle the lines (the first line is always the slow one, by the same ratio). Is there something going on that I'm not aware of? Perhaps this happens because this block is inside a try/catch?

  • Can I use drawRect to refresh a UIView subclass?

    - by Timbo
    I've created a subclass of UIView called Status which is designed to display a rectangle of a certain size (within a view) depending on the value of a variable. // Interface #import <Foundation/Foundation.h> #import <QuartzCore/QuartzCore.h> @interface Status: UIView { NSString* name; int someVariable; } @property int someVariable; @property (assign) NSString *name; - (void) createStatus: (NSString*)withName; - (void) drawRect:(CGRect)rect; @end // Implementation #import "Status.h" @implementation Status @synthesize name, someVariable; - (void) createStatus: (NSString*)withName { name = withName; someVariable = 10000; } - (void) drawRect:(CGRect)rect { CGContextRef context = UIGraphicsGetCurrentContext(); //Draw Status CGContextSetRGBFillColor(context, 0.0, 0.0, 1.0, 1); // fill CGContextFillRect(context, CGRectMake(0.0, 0.0, someVariable, 40.0)); } //// myviewcontroller implementation - (void) viewDidAppear:(BOOL)animated { [super viewDidAppear:animated]; myStatus = [[Status alloc] initWithFrame:CGRectMake(8,8,200,56)]; myStatus.backgroundColor = [UIColor grayColor]; [self.view addSubview:myStatus]; } How do I set this up so I can repeatedly call a refresh of the status bar? I'll probably call the refresh 4 times per second using a NSTimer, I'm just not sure what to call or if I should move this rectangle drawing to a separate function or something... Thanks in advance for your help :)

  • CoreData and many NSArrayController

    - by unixo
    In my CoreData Application, I've an outline view on left of main window, acting as source list (like iTunes); on the right I display a proper view, based on outline selection. Each view has its components, such as table view, connected to array controller, owned by the specific view. Very often different views display same data, for example, a table view of the same entity. From a performance point of view, is better to have a single array controller per entity and share it between all views or does CoreData cache avoid memory waste?

  • Faking a UITableView selection

    - by John Smith
    I have a UITableView where a selection displays some cool stuff in another part of the display. I tried to fake a keypress by writing: NSIndexPath *ip = [NSIndexPath indexPathForRow: 1 inSection:0]; [tableView selectRowAtIndexPath:ip animated:NO scrollPosition:UITableViewScrollPositionTop ]; [self tableView:tableView didSelectRowAtIndexPath:ip]; However it seems the last line is not being run. How can I make it run?

  • iPhone NSMutableDictionary setObject forKey after initWithContentsOfFile

    - by andrew
    so here's my function + (void) AddAddress:(NSString*)ip:(NSString*)mac { NSMutableDictionary* currentAddresses = [[NSMutableDictionary alloc] initWithContentsOfFile:[self filePath:ADDRESSES_FILE]]; [currentAddresses setObject:mac forKey:ip]; [Configuration Write:currentAddresses]; [currentAddresses release]; } [self filePath:ADDRESSES_FILE] returns a string containing the full path of a file (ADDRESSES_FILE) located in the Documents. The file may not exist, in this case I want to just write an object to the dictionary and then write it down the problem is that when i do setObject forKey it doesn't add anything to the dict (if i just do alloc init to the dict, it works fine, but i want to read the records from the file, if there are any, and replace/add a record by using the AddAddress function)

  • Code Interaction with Quartz Composition

    - by Alberto MQO
    Hi, i have a Quartz Composition with a Cube, and X/Y/Z rotation inputs are published. On Interface Builder i made a QCView and a QCPatchController with the previous Quartz Composition loaded. In QCView the Patch Controller is binded, and the rotation published ports are binded too to three NSSlider, so when i change the value of the NSSlider's then the cube rotates. All this works fine, but i want to change the rotation values of the cube from the App Delegate on XCode. I tried to change the value of the NSSliders with IBoulets pointing to them, but this change doesnt apply to the cube, like it does when i change the Sliders directly with my mouse. What should i instanciate and/or how to access and change this Input_Ports.value throught the CQPatchController? Thank you very much for reading, i really need help!

  • UIView as dictionary key?

    - by subw
    I want to have a NSDictionary that maps from UIViews to something else. However, since UIViews do not implement the NSCopying protocol, I can't use them directly as dictionary keys.
