I am making one application in which i want to parse pdf document.I dont know how to implement.Please provide me some sample code and document.thanks in advance.
Hi guys!
First of all, sorry for my posibly bad english...
I got a surely big stupid question...
In my enterprise have an automatic door system, that is opened with a HTTP GET request to a file.
Example:
http://ipaddress/rc.cgi?o=1,50
Where the o=number indicates the amount of seconds that the automatic door will run.
The is no need for authentification or nothing (that is made by LAN Radius).
So, the question is...
How can I make a single button (for example in the springboard) that when you touch it, runs the GET request?
You thing that it should be possible with NSURLConection ?
Thanks for all
I have an iPad application that pulls in all of its data from an external web service. I am working on building in a demo mode that will use a cache of demo data stored on the device so it can be demoed and tried out without the web service connection (or an internet connection.)
Is there a project or good practices standard to follow to model this type of sample data? I'm expecting JSON arrays/Dictionaries back from my web service, how could I build a function that uses hardcoded data to create the NSMutableData object I'd expect to get back from a JSON web request?
i have a c++ class with CGrect variable and i'm getting segfault when trying to access it.
class Parent
{
//with some virtual functions/dtors
};
class Child
{
public:
void SetRect(CGRect rect) { mRect = rect; }
CGRect GetRect() { return mRect; }
int GetIndex() { return mIndex; }
private:
CGRect mRect;
int mIndex;
};
i'm doing
CGRect rect = childPtr->GetRect();
from object c code and it segfaults.
I printed *childPtr just before the call and rect looks fine with intended data value.
int index = childPtr->GetIndex();
from same object c code(*.mm), works fine though.
Any idea why I'm getting segfaults?
Thank you
edit -
It's got something to do with virtual functions.
(gdb) p singlePuzzlePiece-GetRect()
Program received signal EXC_BAD_ACCESS, Could not access memory.
Reason: KERN_PROTECTION_FAILURE at address: 0x00000001
0x00000001 in ?? ()
Cannot access memory at address 0x1
The program being debugged was signaled while in a function called from GDB.
GDB remains in the frame where the signal was received.
To change this behavior use "set unwindonsignal on"
Evaluation of the expression containing the function (at 0x1) will be abandoned.
(gdb)
Somehow, the function is not properly compiled?
I've got an app that's approved by Apple and ready-for-sale, but we're holding off for a few days for press reasons. Anyone know of a way to distribute this thing to beta testers without dealing with UDIDs or jailbreaking phones? Does it matter that it's approved, can I just give select users a file without the provisional stuff?
I have an app with a tab bar, and nav controllers in each tab. When user shakes the device, a UIImageView appears as a child view in the nav controller. But the UIImageView must contain a special image, depending on the device's current orientation.
If I write just
- (void)willAnimateRotationToInterfaceOrientation:(UIInterfaceOrientation)
if (interfaceOrientation == UIInterfaceOrientationPortrait|| interfaceOrientation == UIInterfaceOrientationPortraitUpsideDown) {
//Code
}
else if (interfaceOrientation == UIInterfaceOrientationLandscapeRight||interfaceOrientation == UIInterfaceOrientationLandscapeLeft) {
//Code
}
}
The view just goes crazy if user rotated the device before shaking. Is there a method to get iPhones current orientation?
Hello. I am a student programmer who has taken up Objective-C on my free time as my college doesn't teach it. We have only used Java and basic C so far. I am in the middle of making a program for the iPod and was wondering if there was any type of way to call a method in a class similar to the way a Focus Listener does in Java? I have a view that I would like to call a refresh method (to update the newly inputted titles of buttons from another view) when the view is put at the top and visible again. Is this too easy or is there a more methodical way of doing that? I have tried to just call the method from the other view class but it does not seem to work (says the other class is either undefined or may not accept the method call and crashes on execution).
Any insight would be appreciated. Thank you for your time.
I am creating an SDK for a client that includes predefined view controllers. What is the recommended way to package everything (static lib, .xib(s), and .png(s)) for easy use?
SDKs that I've used (e.g. Pinch Media) do a good job of just providing a .h and .a file that expose only user accessible functionality and hiding everything else. As I read Apple's documentation, a framework would be ideal but is not permitted on iPhoneOS.
Some key requirements:
Don't expose source or object
internals.
Be easy to use & set up.
Work on both the device and simulator.
Thanks!
I have a root view controller with no nib file,
I tried adding this at cellForRowAtIndexPath as that passes in a UITableView as tableView.
So I put :
tableView = [[UITableView alloc] initWithFrame:self.view.frame style:UITableViewStyleGrouped];
It ran with no error but it didnt seem to change anything.
Basically -[UIApplication openURL:] would be perfect, if it wasn't for the fact that it doesn't work within the same application (at least on simulator -- if this works on device someone please tell me). It's not a super big deal though if it just relaunches w/o URLness since I can obviously just persist some data. The goal of this is to essentially free all memory in the application and call all of the loading procedures.
I'm fairly new to Objective-C and am confused on what falls under the unbrella of a "private API" that could cause Apple to reject my app. Does this include adding methods to existing classes? For example, I found some code on stackoverflow to recolor the tab bar icons for UITabBars with this extension to the UITabBarItem class. Is this considered a "private API"? If not, what does?
@interface UITabBar (ColorExtensions)
- (void)recolorItemsWithImage:(UIImage *)image shadowColor:(UIColor *)shadowColor shadowOffset:(CGSize)shadowOffset shadowBlur:(CGFloat)shadowBlur;
@end

Thanks in advance.
Hello. I am looking for those arrow icons (a left white arrow and a white right arrow) that are used on the lower toolbar of the Photo Library (or Camera Roll). I also have seen them on the Facebook app and some other custom apps. I am surprised that they are not built in "UIBarButtonSystemItem" icons. Can anybody point me to these icons?
We are creating a video intensive app and want to be sure that adaptive streaming is required (given that we need to write an automated transcoding and segmentation system to support this). Does anyone know if the YouTube app is using adaptive streaming?
In what format the content data is placed on server so that when user buy content from server he can use new content . also if this data is in compressed format then how to uncompress it in application ?
Has anyone had any experience of this? Is it easy? I know very little C, but all I want to do is package the web app as a native app. Is that allowed by Apple anyway?
Thanks!
Hi.
Among many animation scenarios, there are times when I want an object to move a straight line then change direction, move another straight line and so forth.
Assuming I would use either UIImageView or CABasicAnimation with image arrays.
Does it make difference to provide more images when the object is moving in a straight line?
For example,
point1 ---------point2 ------- point3 (all points are in a straight line)
Providing an image at point2 to UIImageView or CABasicAnimation, gives any better animation result, assuming I don't need to change the animation speed along the course?
If I were flashing each image myself, yes it would make the animation look smooth, but I'm giving the images to UIImageView/CABasicAnimation, and wonder what they do.
Thank you
