Hello,
I'm trying to use the NSStream objects to open and then write and read on a socket but i have a problem.
I don't know how to write on the socket, after i have opened it.
Here is how i have done
1) first openning the socket :
NSURL *website = [NSURL URLWithString:urlStr];
if (!website) {
NSLog(@"%@ is no...
Is there anyway to test CoreLocation on the iPhone Simulator?
All I require is to be able to set the location myself and have CoreLocation return it.

Actually I would say: yes, the Getter is the owner. So anyone who calls the Getter is not responsible for freeing the memory. Or more precisely, the object itself is the owner, but the Getter acts as a delivery mechanism of the instance variable to others. Is that right, or did I get that wrong?

I have a static library that includes some xibs. These will basically be the same across projects. I'd like to include the xibs as part of the library. I can include their veiwcontrollers, reference these controllers in the calling project but then there isn't a xib to load. When I right click the xib in the library project, it can't...
Below is a block of code that runs in a separate thread from my app's main thread. How do I get the UI to update after each button gets its thumbnail? Right now it doesn't update until the whole method finishes. The buttons are already added to a UIScrollView.
(LotsGridButton is just a UIButton with some extra properties.)

I've created a new View-based Application in XCode.
In the ViewController, the only code that I've modified looks like this:
- (void)viewDidLoad {
[super viewDidLoad];
UIView *newView = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 200, 200)];
newView.backgroundColor = [UIColor redColor];
[self.view addSubview:newView];

I'm trying to draw a shadow under the bottom edge of a UIView in Cocoa Touch. I understand that I should use CGContextSetShadow() to draw the shadow, but the Quartz 2D programming guide is a little vague:
Save the graphics state.
Call the function CGContextSetShadow, passing the appropriate values.
Perform all the drawing to which you ...
I've been reading that if I have something like this:
@property (nonatomic, assign) UIView *anView;
Then I don't have to care about memory management. I don't have to do [anView release] in the -dealloc method.
Why?
"assign" just tells the compiler: "Hey man, this property does not retain whatever anyone assigns to it". And then you...
Somewhere I was reading that - regarding low memory warnings and giving up an non-visible view with all it's subviews (= a whole nib, I think), you should do that:
-(void)dealloc {
[anView release], anView = nil;
[someImageView release], someImageView = nil;
[super dealloc];
}
rather than
-(void)dealloc {
[anView rel...
Hey,
is there a way to connect the iPhone with Sharepoint?
I wonder, if it is possible to implement the HTTP or WEBDAV
protocol of Sharepoint in Cocoa/Objective-C.

I managed to design a fairly decent launch image/default.png. But I noticed that it just flashes for a second then goes to the UI. Is it possible to code the launch image and make it dynamic? Remaining on screen until the user touches it or a button. Or is this something one would definitely not want to do?
Thanks,
~D1~

If I define an property and just do:
@property(nonatomic) UIButton* button;
then I think that it's an "assign" property. Is that correct?

Like I understand, @synthesize actually is generating the Getters and Setters. But what's @property then doing? Is it just setting up the parameters for that cool @synthesize magic function?

I have an application that has a UITableView. This UITableView is populated by an NSMutableArray being held (as a property) in the appDelegate. You can think of this as an email window. It lists messages in a subclassed UITableViewCell. When a new message appears, I have all the code done which downloads the message, adds the data to the...
I wrote this function in a Helper class for reading a table from my database, and returning it to my controller.
On my viewdidload, i cache this result into a class variable (retain property set) and trying to use that inside a picker view control's delegate method. (titleForRow)
Somehow, I get a EXC_BAD_ACCESS when I try to access the...
Hello, I have a question dealing with UIButton and it's hit area. I am using the Info Dark button in interface builder, but I am finding that the hit area is not large enough for some people's fingers.
Is there a way to increase the hit area of a button either programmatically or in Interface Builder without changing the size of the I...
Hello again. I am wondering if anyone has used the userInteractionEnabled method on a UILabel to allow the label to act like a button (or just to fire off a method). Any help would be greatly appreciated. Cheers!
Update (4/30/09 @1:07pm) Clarification: I have a standard InfoButton and next to it I want to place a label with the text...
In reference to this related question on stackoverflow:

As my question in the subject above states, what requirements do you typically have to meet in order to say "Ok, I need encodeWithCoder: and initWithCoder: instantiation for this"? Typically you can write object state to NSUserDefaults, so I'm curious when do you experts decide to use one vs the other?

Hi hi. Does anyone know of a quick way to dump the standardUserDefaults of NSUserDefaults via NSLog? This is what I have:
NSLog(@"NSUserDefaults dump: %@", [NSUserDefaults standardUserDefaults]);
But it returns:
NSUserDefaults dump: <NSUserDefaults: 0x50b520>
...which is not quite what I'm looking for. I'd really like to have ke...
