hi,
i want to use webDAv server to share files among systems and (iPod or iPhone)in my iphone project.to use it,i have to use individual webserver?
or is it a built in facility ? any one can help?
I'm a newbie in iPhone Programming. I'm trying to send a message from one view controller to another. The idea is that viewControllerA takes information from the user and sends it to viewControllerB. viewControllerB is then supposed to display the information in a label.
viewControllerA.h
#import <UIKit/UIKit.h>
@interface viewControllerA : UIViewController
{
int num;
}
-(IBAction)do;
@end
viewControllerA.m
#import "viewControllerA.h"
#import "viewControllerB.h"
@implementation viewControllerA
- (IBAction)do {
//initializing int for example
num = 2;
viewControllerB *viewB = [[viewControllerB alloc] init];
[viewB display:num];
[viewB release];
//viewA is presented as a ModalViewController, so it dismisses itself to return to the
//original view, i know it is not efficient
[self dismissModalViewControllerAnimated:YES];
}
- (void)dealloc {
[super dealloc];
}
@end
viewControllerB.h
#import <UIKit/UIKit.h>
@interface viewControllerB : UIViewController
{
IBOutlet UILabel *label;
}
- (IBAction)openA;
- (void)display:(NSInteger)myNum;
@end
viewControllerB.m
#import "viewControllerB.h"
#import "viewControllerA.h"
@implementation viewControllerB
- (IBAction)openA {
//presents viewControllerA when a button is pressed
viewControllerA *viewA = [[viewControllerA alloc] init];
[self presentModalViewController:viewA animated:YES];
}
- (void)display:(NSInteger)myNum {
NSLog(@"YES");
[label setText:[NSString stringWithFormat:@"%d", myNum]];
}
@end
YES is logged successfully, but the label's text does not change. I have made sure that
all of my connections in Interface Builder are correct, in fact there are other (IBAction)
methods in my program that change the text of this very label, and all of those other methods work perfectly...
Any ideas, guys? You don't need to give me a full solution, any bits of information will help. Thanks.
how does one use code to do this:
produce 15 random numbers that are not in any order, and that only occur once
eg.
1 4, 2, 5, 3, 6, 8, 7, 9, 10, 13, 12, 15, 14, 11
rand() or arc4rand() can repeat some, which is not what im after.
Thanks
Today my app approved, but I got emails from users says it crash. I figured out that
[[UIApplication sharedApplication] setStatusBarHidden:YES withAnimation: UIStatusBarAnimationSlide];
Is the problem, Because users have firmware 3.1.x this API is not working and app crash.
So I have replace it with
if ([[[UIDevice currentDevice] systemVersion] floatValue]>=3.2)
[[UIApplication sharedApplication] setStatusBarHidden:YES withAnimation: UIStatusBarAnimationSlide];
else
[[UIApplication sharedApplication] setStatusBarHidden:YES animated:YES];
My questions...
Is what I did the best solution?
Why XCODE did not warn me that SetStatusBarHidden withAnimation is not in 3.0 while I set my Traget OS firmware 3.0?
Do I have to check on every API to see if it is working with my Target OS?
Thank you

I am resuing ListPreference for a setting which I store in the database. I do not want it stored in the preference file.
How can I reuse ListPreference in such way that it does not save to SharedPreference file?
I've seen in applications a popup that prompts me what I do want to do with a text. I am prompted to choose from Send by SMS, Send by Email, Send by Bluetooth, Send by Fring etc.
How do I make such a popup, it seamed to be automatically built?
Also how do I tell what message to use?
And if needed how do I tell who the contact is? Maybe chooses the options based on the contact, (if has email, show email)
Has anyone come across a strange behaviour with the Camera API when used on Sony-Ericsson X10 or Droid?
For example the following code doesn't work on those devices. As a result I'm getting a lot of negative feedback on the Market translating into many cancelled orders...
mParameters.set("rotation", orientation);
mParameters.set("jpeg-quality", img_quality);
mParameters.set("picture-size", "1024x768");
mCamera.setParameters(mParameters);
Could you suggest an alternative way of achieving the same? Thanks.

I've got a couple of Core Data-generated class files that I'd like to add custom methods to. I don't need to add any instance variables. How can I do this?
I tried adding a category of methods:
// ContactMethods.h (my category on Core Data-generated "Contact" class)
#import "Contact.h"
@interface Contact (ContactMethods)
-(NSString*)displayName;
@end
...
// ContactMethods.m
#import "ContactMethods.h"
@implementation Contact (ContactMethods)
-(NSString*)displayName {
return @"Some Name"; // this is test code
}
@end
This doesn't work, though. I get a compiler message that "-NSManagedObject may not respond to 'displayName' " and sure enough, when I run the app, I don't get "Some Name" where I should be seeing it.
Hi,
I have to manage xml's and Strings in my app.
by efficenty and memory saving, is collection(ArrayList) will be much more 'expensive' then array of Strings?
another issue is: i could use the content as regular String, or XML.. is working with XML also makes it more 'expensive' ?
when i say i expensive i talk about taking system sources.
please tell me by any of your exprience if the diffrences are significant?
thanks,
ray.

Hi Guys, Do you know what could cause this as a return for a Facebook Canvas app. It works for most users of our site but some users, it generates this and i cant figure out what would cause this. The userID is returned as 0 and the Token seems to be missing something. there is no other way for the users to reach the site other than visiting the Facebook App page... Please let me know what i can do to prevent this from happening
UserID: 0
Token: 104743107829|b8bbc20eac6127d8a9a85451490a0663

I need to set sounds for different players in my game. There are 10 players. And I have 10 sounds.
The players are loaded int his way
for( int i = 1; i <5; i++ )
{
[playerAnimation addFrameWithFilename: [NSString stringWithFormat:@"Player %02d gun draw_%02d.png", playerNumber, i]];
}
How can I set the sounds in this way by giving the filenames. And player1 shoots player1sound should play.
How can I do it using
[[SimpleAudioEngine sharedEngine] playEffect:@"player1.sound.wav"];
I have a ViewController that has its own NIB. I would like to embed that NIB inside of another master NIB. How can I accomplish this in Interface Builder and how do I reference it in code?
Hello all,
i am using an example from the iphone developer book from apress.
the problem is that this example only works on the simulator im trying to figure out how i can make it work on the device. This chapter isn't working at all. below is the sample code. data.plist is located in the resource folder.
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentsDirectory = [paths objectAtIndex:0];
return [documentsDirectory stringByAppendingPathComponent:kFilename];
Below then checks to see if the file is located. this is skipped, so im guessing this does not find the file.
if ([[NSFileManager defaultManager]fileExistsAtPath:filePath]) {
NSArray *array = [[NSArray alloc] initWithContentsOfFile:filePath];
BGDataSave = [array objectAtIndex:0];
NSLog(@"%@", BGDataSave);
price.text = [array objectAtIndex:1];
percent.text = [array objectAtIndex:2];
salepriceLabel.text = [array objectAtIndex:3];
origpriceLabel.text = [array objectAtIndex:4];
}
hi,

hi,i coded like
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
UIButton *btn = [UIButton buttonWithType:UIButtonTypeRoundedRect];
btn.frame = CGRectMake(230.0f, 4.0f, 60.0f, 36.0f);
[btn setTitle:@"OK" forState:UIControlStateNormal];
[btn setTitle:@"OK" forState:UIControlStateSelected];
[btn addTarget:self action:@selector(onClickRename:) forControlEvents:UIControlEventTouchUpInside];
[cell addSubview:btn];
return cell;
}
but if the user selects the button on particular row, i can change that image through onClickRename...but can i get inwhich row's image has been touched through
(void)tableView:(UITableView )tableView didSelectRowAtIndexPath:(NSIndexPath)indexPath ?
Title is quite self explanatory, but I have some animation being done in a loop triggered by CADisplayLink. However, as soon as I scroll a UIScrollView I have added to my view hierarchy, the animation stops immediately, only to return again when scrolling has completely stopped and come to a standstill....
Anyway to cancel this behaviour?
Hi all, Could someone please tell me how to make an image appear when the user taps the screen and make it appear at the position of the tap. Thanks in advance, Tate
I have a custom table cell. In it I have put (via the IB) an image view of a certain frame
In 'cellForRowAtIndexPath', under certain conditions, I would like to modify the frame of this UIImageView, so I write something like:
UIImageView *imgv = (UIImageView *)[cell viewWithTag:1];
CGRect r = CGRectMake(20.0, 20.0, 10.0, 10.0);
imgv.frame = r;
But nothing expected happens (The frame does move a little though not to where I want, but doesn't change its size at all);

I have a particular link to a video file in server. when i load the safari through
[[UIApplication sharedApplication] openURL:[NSURL URLWithString:@"http://mydomain/category/2.mp4"]];
simulator pops out an alert message saying that "Cannot Play MOVIE.. Server is not correctly configured".......
Even I tried using the mediaPlayer framework - MPMoviePlayerController and loading it with th e url-"http://mydomain/category/2.mp4" but it didnt play out.
when i paste the same url in the 10.5 leopards safari it plays out smoothly..
What may be the reason behind it.?
