Is there such a thing as an "on load complete" for images in iphone?
I want to be able to destroy a UIActivity indicator once and image is loaded.
What the general best practice for doing this?
When I start editing a UITextField, I have the "Clear When Editing Begins" option checked so it starts off with no text. However, the "Return" button is grayed out until you type at least one character.
I've seen other iphone apps where the "Return" button is not grayed out (and if you press it with no text, then it goes back to what the text used to be). How is this done?
Thanks.

Is there any way of placing a file into application "sandbox" i.e into eg:
/var/mobile/Applications/30B51836-D2DD-43AA-BCB4-9D4DADFED6A2/Documents
of iphone?
My Application expects a file to be put into /Documents folder of application so that it can be uploaded to my local server.
This method should confirm to the rules of Apple so that it should not be rejected.
iPhone Safari seems to have some sort of problem whereby a page with css like this:
body {
background: #000 url(fixedimage.png) fixed repeat-x;
}
...doesn't actually lead to a fixed image. It scrolls as the user scrolls.
I've seen plenty of people kvetching about this on the internets, but no real solution. Does anyone have any ideas?

Many are saying that Apple has restricted it for better performance. It should increase the size of RAM to support multitasking. So, they Apple is not allowing it.
But some say that Cocoa Touch applications can't be multitasking as iPhone has only one window and views on it. But I could not understand what is the correct reason for this ?
Please clarify me.
I am writing an iPhone app which will start with asking the user to register with a login/passwd. These should be :
Saved securely locally
Send securely to a remote web-server
What do I need to achieve the above? Say, for local storage, shall I save them in a file or database? Shall I encrypt it? For sending it over, is HTTPS sufficient?
What's the battery time of iPhone 3G and 3Gs with GPS active? I'm getting approx. 2 hours of battery life with active GPS (Note: I'm using my own App).
When you use facebook connect on the iPhone do you have to use the supplied login button and login screen built into the framework? The reason I ask is because I'm also using twitter and I would like to have the same user experience when they log in to user as they have when they log in to facebook. So I can either replicate the login screen facebook connect uses for twitter or just not use the facebook connect login screen all together.
I can't find any support for GL_TEXTURE_RECTANGLE_ARB in OpenGL ES. Is there any extension specific for iPhone or iPad which can render arbitrary sprites (non power of two)?
Thanks for help.
Hi,
How I can write a phone number in the xhtml file and when the user clicks (on the number) the iphone call automatically (to that number)?
Any ideas?
Thanks :-)
I am newbie to iPhone programming. I am not using Interface Builder in my programming. I have some doubt about memory management, @property topics in iPhone.
Consider the following code
@interface LoadFlag : UIViewController {
UIImage *flag;
UIImageView *preview;
}
@property (nonatomic, retain) UIImageView *preview;
@property (nonatomic, retain) UIImage *flag;
@implementation
@synthesize preview;
@synthesize flag;
- (void)viewDidLoad
{
flag = [UIImage imageNamed:@"myImage.png"]];
NSLog(@"Preview: %d\n",[preview retainCount]); //Count: 0 but shouldn't it be 1 as I am retaining it in @property in interface file
preview=[[UIImageView alloc]init];
NSLog(@"Count: %d\n",[preview retainCount]); //Count: 1
preview.frame=CGRectMake(0.0f, 0.0f, 100.0f, 100.0f);
preview.image = flag;
[self.view addSubview:preview];
NSLog(@"Count: %d\n",[preview retainCount]); //Count: 2
[preview release];
NSLog(@"Count: %d\n",[preview retainCount]); //Count: 1
}
When & Why(what is the need) do I have to set @property with retain (in above case for UIImage & UIImageView) ? I saw this statement in many sample programs but didn't understood the need of it.
When I declare @property (nonatomic, retain) UIImageView *preview; statement the retain Count is 0. Why doesn't it increase by 1 inspite of retaining it in @property.
Also when I declare [self.view addSubview:preview]; then retain Count increments by 1 again. In this case does the "Autorelease pool" releases for us later or we have to take care of releasing it. I am not sure but I think that the Autorelease should handle it as we didn't explicitly retained it so why should we worry of releasing it.
Now, after the [preview release]; statement my count is 1. Now I don't need UIImageView anymore in my program so when and where should I release it so that the count becomes 0 and the memory gets deallocated. Again, I am not sure but I think that the Autorelease should handle it as we didn't explicitly retained it so why should we worry of releasing it. What will happen if I release it in -(void) dealloc method
In the statement - flag = [UIImage imageNamed:@"myImage.png"]]; I haven't allocated any memory to flag but how can I still use it in my program. In this case if I do not allocate memory then who allocates & deallocates memory to it or is the "flag" just a reference pointing to - [UIImage imageNamed:@"myImage.png"]];. If it is a reference only then do i need to release it.
Thanks in advance.
