  • Creating 1 page PDF of iPad Screen view - How?

    - by user314695
    Hi All, I've asked this question on a couple other forums and have had zero response, so I'm hoping someone here can help point me in the right direction. I have a pretty simple one screen application for my work. It's basically just a recreation of a 1 page paper report that has a company logo, some labels, a few text boxes and a scroll text box for the report. I need to be able to fill out the report then click a button to save it in a graphical form so I can fax, print or email it later. Currently, I'm just programmatically taking a screen capture and saving it to the photo's library (default for screen capture). Then I can just email it from photo's. This works ok, but is kind of hacky, at best. I've read through the new iPad 3.2 guide for creating PDF's (apparently it's supposed to be much easier than before) but I can not get it to work and I've spent countless hours on it now. I'm hoping someone has the answer for me. Alternatively, if anyone knows how I can redirect where the screen capture is stored (default is in the photo album) then maybe I can make that function work. If I could redirect the screen capture to store in my applications document folder, then I can use MFMailCompose to attach it to an email. Lastly, on a side note, does anyone know of a good way to capture a digital signature via touch. For instance, I'd love to have my users be able to just sign their name via touch at the bottom of the document before I convert to PDF or take a screen capture. Thanks in advance for your help. -Ray

  • How to reset the context to the original rectangle after clipping it for drawing?

    - by mystify
    I try to draw a sequence of pattern images (different repeated patterns in one view). So what I did is this, in a loop: CGContextRef context = UIGraphicsGetCurrentContext(); // clip to the drawing rectangle to draw the pattern for this portion of the view CGContextClipToRect(context, drawingRect); // the first call here works fine... but for the next nothing will be drawn CGContextDrawTiledImage(context, CGRectMake(0, 0, 2, 31), [img CGImage]); I think that after I've clipped the context to draw the pattern in the specific rectangle, I cut out a snippet from the big canvas and the next time, my canvas is gone. can't cut out another snippet. So I must reset that clipping somehow in order to be able to draw another pattern again somewhere else? Edit: In the documentation I found this: CGContextClip: "... Therefore, to re-enlarge the paintable area by restoring the clipping path to a prior state, you must save the graphics state before you clip and restore the graphics state after you’ve completed any clipped drawing. ..." Well then, how to store the graphics state before clipping and how to restore it?

  • UITableView: Highlighted cell after switching back views

    - by Matthias
    Hi, I'm using a UINavController together with some UITableViews to display a kind of drill down for some data (e.g. like the Contact App). Works well. The only problem I have is, when I select a cell in the first table view it is highlighted, then the view switches to the next level and then, if I go back to the first level, the cell is still highlighted. So, how can I reset the highlighting when switching back? Thanks for your help. Regards Matthias

  • What's the most effective path to top level development?

    - by Glycerine
    I got a questions asked from one of my delegates the other day, "how did you get to where you are in programming?" I'm now at a java application realm - and I'm just about OK at it. the path that brought me there: BASIC VB6 PHP javascript actionscript java/objective-C I still live in the web development but I now prefer java - I see this as a good flow but I was wondering how you guys got to where you are and the best path to take? Edit: reword I guess I've asked the question wrong - I was wondering how to progress to a top level application from starting off in development. Where good paradyms connect languages. I won't have considered C++ as my first language see.

  • Implementing activity indicator

    - by Prash.......
    I am implementing an activity indicator in my application. In my application on button click a webservice is called and it takes some time. To show the user that process is going on I implemented an activity indicator: CGRect frame = CGRectMake(140, 300, 40, 37); UIActivityIndicatorView *activityIndicator = [[UIActivityIndicatorView alloc] initWithFrame:frame]; activityIndicator.activityIndicatorViewStyle = UIActivityIndicatorViewStyleGray; [self.view addSubview:activityIndicator]; This Snippet is written in viewDidLoad() method, and I have an action called, -(IBAction)agree:(id)sender { //here webservice is called } I have to start that activity by [activityIndicator startAnimating]; But I am unable to start that activityIndicator, please suggest a proper solution for that.

  • What's the best way to return different cells depending on position in a UITableView

    - by Robert Conn
    I have a grouped UITableView that has 3 sections and a number of cells in each section that each need to be a different custom cell, with different display requirements. I currently have a large if statement in cellForRowAtIndexPath, with each branch instantiating and returning the appropriate custom cell based on interrogating the indexPath's section and row properties. e.g. if (indexPath.section == 0 && indexPath.row == 0) { // instantiate and return cell A } else if (indexPath.section == 1 && indexPath.row == 2) { // instantiate and return cell B } //etc etc What is best practice for this scenario? A large if statement does the job, but is it the best implementation?

  • Remembering state: content offset and table cell reuse.

    - by Attacus
    I have a tableview with cells that have a scrollview in them. The scrollview is paged, 2 pages to be exact, and is meant to be able to quickly compare two small blocks of text. I'm trying to find a way to remember what the content offset of the scrollview is. Cell reuse is killing me. I've tried resetting the offset in prepareForReuse or directly in the cellForRowAtIndexPath, but it seems to give me exactly what you'd expect: Randomly offset tablecells after reuse. Anyone have any ideas?

  • How can I make a UIButton "flash" (with a glow, or changing its image for a split second)

    - by marty
    I tried just making the image switch to black and then use sleep(1) and have it go back to the original image, but the sleep doesn't work at the right time, and I can't even see the black flash it goes so fast. [blueButton setImage:[UIImage imageNamed:@"black.png"] forState:UIControlStateNormal]; sleep(3); [blueButton setImage:[UIImage imageNamed:@"blue.png"] forState:UIControlStateNormal]; I just want to make it give a indicator to this button. Any thoughts? Thanks.

  • Using a Data Management Singleton

    - by Dan Ray
    Here's my singleton code (pretty much boilerplate): @interface DataManager : NSObject { NSMutableArray *eventList; } @property (nonatomic, retain) NSMutableArray *eventList; +(DataManager*)sharedDataManager; @end And then the .m: #import "DataManager.h" static DataManager *singletonDataManager = nil; @implementation DataManager @synthesize eventList; +(DataManager*)sharedDataManager { @synchronized(self) { if (!singletonDataManager) { singletonDataManager = [[DataManager alloc] init]; } } NSLog(@"Pulling a copy of shared manager."); return singletonDataManager; } So then in my AppDelegate, I load some stuff before launching my first view: NSMutableArray *eventList = [DataManager sharedDataManager].eventList; .... NSLog(@"Adding event %@ to eventList", event.title); [eventList addObject:event]; NSLog(@"eventList now has %d members", [eventList count]); [event release]; As you can see, I've peppered the code with NSLog love notes to myself. The output to the Log reads like: 2010-05-10 09:08:53.355 MyApp[2037:207] Adding event Woofstock Music Festival to eventList 2010-05-10 09:08:53.355 MyApp[2037:207] eventList now has 0 members 2010-05-10 09:08:53.411 MyApp[2037:207] Adding event Test Event for Staging to eventList 2010-05-10 09:08:53.411 MyApp[2037:207] eventList now has 0 members 2010-05-10 09:08:53.467 MyApp[2037:207] Adding event Montgomery Event to eventList 2010-05-10 09:08:53.467 MyApp[2037:207] eventList now has 0 members 2010-05-10 09:08:53.524 MyApp[2037:207] Adding event Alamance County Event For June to eventList 2010-05-10 09:08:53.524 MyApp[2037:207] eventList now has 0 members ... What gives? I have no errors getting to my eventList NSMutableArray. But I addObject: fails silently?

  • Custom inputAccessoryView push my UITableView first row partially off the screen

    - by TonyMocha
    Hi For my scenario, I have a UITableView with a UITextField for the first row. While I try to set custom toolbar for keyboard with UITextField.inputAccessoryView, it pushed my first row of textfield partially off the screen. This is not happening if I avoid adding the toolbar. Refer screen shot below: I tried with NSNotification with keyboardWillShow by reposition to first row of the tableview, but it just look awkward for the table pulling out and in. It might be something to do overriding UITableView/UIScrollView, but I am out of idea how to do this. Would like to know how you guys resolve this. Thanks you!
