  • 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

  • Urban Airship Tags issue

    - by Moshe
    I modified the alias sample code from: [request addRequestHeader: @"Content-Type" value: @"application/json"]; [request appendPostData:[[NSString stringWithFormat: @"{\"alias\": \"%@\"}", self.deviceAlias] dataUsingEncoding:NSUTF8StringEncoding]]; to: [request addRequestHeader: @"Content-Type" value: @"application/json"]; [request appendPostData:[[NSString stringWithFormat: @"{\"tags\": \"%@\"}", offsetStr] dataUsingEncoding:NSUTF8StringEncoding]]; offsetStr is a string containing a Timezone offset (which can be any number between -12 and 12). For some reason, Urban Airship is making each character of the string into its own tag. I've tried to substitute the - for a string neg with the same results. What's wrong?

  • Big time Leaking in Objective-C Category

    - by Daniel Amitay
    I created a custom NSString Category which lets me find all strings between two other strings. I'm now running into the problem of finding that there are a lot of kBs leaking from my script. Please see code below: #import "MyStringBetween.h" @implementation NSString (MyStringBetween) -(NSArray *)mystringBetween:(NSString *)aString and:(NSString *)bString; { NSAutoreleasePool *autoreleasepool = [[NSAutoreleasePool alloc] init]; NSArray *firstlist = [self componentsSeparatedByString:bString]; NSMutableArray *finalArray = [[NSMutableArray alloc] init]; for (int y = 0; y < firstlist.count - 1 ; y++) { NSString *firstObject = [firstlist objectAtIndex:y]; NSMutableArray *secondlist = [firstObject componentsSeparatedByString:aString]; if(secondlist.count > 1){ [finalArray addObject:[secondlist objectAtIndex:secondlist.count - 1]]; } } [autoreleasepool release]; return finalArray; } @end I admit that I'm not super good at releasing objects, but I had believed that the NSAutoreleasePool handled things for me. The line that is leaking: NSMutableArray *secondlist = [firstObject componentsSeparatedByString:aString]; Manually releasing secondlist raises an exception. Thanks in advance!

  • Clear button at uisearchbar not working at all

    - by kevin.ng
    I created a search bar programmatically and added to my view using the codes below: - (void)viewDidLoad { searchBar = [[UISearchBar alloc] initWithFrame:CGRectMake(xPositionForSearchBar, yPositionForSearchBar, widthForSearchBar, heightForSearchBar)]; UIView *bg = [[searchBar subviews] objectAtIndex:0]; searchBar.delegate = self; searchBar.placeholder = @"Search record"; for(UIView *view in searchBar.subviews){ if([view isKindOfClass:[UITextField class]]){ UITextField *tf = (UITextField *)view; tf.delegate = self; break; } } [bg removeFromSuperview]; [self.view addSubview: searchBar]; } The code is implemented with UISearchBarDelegate and UITextFieldDelegate. I have tried using - (void)searchBarCancelButtonClicked:(UISearchBar *)aSearchBar { NSLog(@"cancel clicked"); searchBar.text = @""; [aSearchBar resignFirstResponder]; } - (BOOL)textFieldShouldClear:(UITextField *)textField { NSLog(@"clear"); [self performSelector:@selector(searchBarCancelButtonClicked:) withObject:searchBar afterDelay: 0.1]; return YES; } and yet, the text inside the searchBar is not cleared at all when i click on the "clear button" - a circle with a "X" inside. The clear button works when I implemented it in IB. Wonder why? Kindly advice, many thanks.

  • How can I know which viewController is being displayed(in view) currently by my appdelegate?

    - by wolverine
    I am doing a normal viewBased application and have added another viewController(along with the xib). When the application starts, normally it will display its own view. I am doing an action and is going to another viewController class. From this class, I want to check which viewController is being displayed currently in the view. How can I do this? Does anyone have an idea?

  • textFieldShouldBeginEditing + UIKeyboardWillShowNotification + OS 3.2

    - by user193545
    I have multiple textfields on a UIView. I resign for a previous textField in textFieldShouldBeginEditing method, where following sequence of events are performed UIKeyboardWillHideNotification is received corresponding to that field where the keyboard for the previous field is hidden. the method textFieldShouldBeginEditing returns a YES and then UIKeyboardWillShowNotification is received where the keyboard for the current field is displayed. However, in OS 3.2 even though textFieldShouldBeginEditing returns a YES, UIKeyboardWillShowNotification for the current field is not received. The logic works for OS < 3.2 Any ideas where I might be doing wrong?

    - by Nic Hubbard
    This is driving me crazy as I cannot figure out what in the world is going on. I load up files form you main bundle all the time, xml files, html files, etc. But, now I am trying to get the contents of a javascript file but it can never find it.

My globaly.js file is in my Resources folder, the exact location where my other files are location that work totally fine using the above method. Why can't it find my js file?

  • nsfetchedresultscontroller with empty sections

    - by WearyMonkey
    I have a database of People and pets, with a one to many relationship Person Pet Name Name Pet <----- Owner I am using a UITableView backed by Core data and a nsfetchedresultscontroller to display the list of pets, grouped into sections by the owner. NSFetchRequest *fetchRequest = [[NSFetchRequest alloc] init]; fetchRequest.entity = [NSEntityDescription entityFromName:@"Pet" inManagedObjectContext:context] NSSortDescriptor *sortDescriptor = [[NSSortDescriptor alloc] initWithKey:@"Owner.name" ascending:YES]; NSArray *sortDescriptors = [[NSArray alloc] initWithObjects:sortDescriptor, nil]; [fetchRequest setSortDescriptors:sortDescriptors]; NSFetchedResultsController *controller = [[NSFetchedResultsController alloc] initWithFetchRequest:fetchRequest managedObjectContext:context sectionNameKeyPath:@"Owner.name" cacheName:@"Root"]; This works to display all pets under their owners section, however I also want to display the empty sections of People who do not have any pets? Is this possible? Thanks for any help.

  • 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 to make same UIWebView take data from different local .html files?

    - by Mike Rychev
    I have an app, where there's one UIWebView and a UITableView. I don't want to create many .xib's, so I decided to make one .xib for all elements of the table. When user chooses a table element, the UIWebView appears and I want it to load data from different .html's depending on the name of the parent controller. I tried this: if (selectedTableElement==@"FirstElement") { [childController.message loadRequest:[NSURLRequest requestWithURL:[NSURL fileURLWithPath:[[NSBundle mainBundle] pathForResource:@"_" ofType:@"html"]isDirectory:NO]]]; } And then myWebView=message; But it didn't work. Thanks in advance!

  • UIButton title disappears on touch

    - by psychotik
    I want a touchable UILabel, but since that's not possible I decided to create a UIButton of type UIButtonTypeCustom. It looks how I want it to look, but when I touch it, the title disappears. I tried setting the title for state UIControlStateHighlighted but that didn't help. I know I'm doing something really silly here, but can't figure it out. I tried a few things (commented in the code below) which didn't seem to help. Here's how I'm configuring the button: UIButton* button = [UIButton buttonWithType:UIButtonTypeCustom]; button.frame = CGRectMake(0, 0, width, height); button.clearsContextBeforeDrawing = YES; button.contentHorizontalAlignment = UIControlContentHorizontalAlignmentLeft; button.contentVerticalAlignment = UIControlContentVerticalAlignmentCenter; button.enabled = YES; button.hidden = NO; button.highlighted = NO; button.opaque = YES; button.selected = NO; button.userInteractionEnabled = YES; button.showsTouchWhenHighlighted = NO; [button setTitle:@"Hello World" forState:UIControlStateNormal]; button.titleLabel.font = [UIFont boldSystemFontOfSize:16]; button.titleLabel.textColor = [UIColor blackColor]; // Things I tried that didn't help //[button setBackgroundColor:[UIColor clearColor]]; //button.titleLabel.text = @"Hello World"; //[button setTitle:@"Hello World" forState:UIControlStateHighlighted]; Any ideas?

  • How to fit more operations to tab bar + navigation bar?

    - by Henry
    I want to use Tabview for my whole app. However in certain view, I have more operations than I can fit in the navigator bar. So I thought of using Toolbar but toolbar should be located at the bottom, right? Toolbar looks weird to be on top of the tabview, and hiding tabview for one view doesn't really make sense. I guess I can go with more buttons in the main view, but any other alternatives? What can one use to add more operation(s) to tabview? Thanks

  • Does NSClassFromString affect performance?

    - by Tomen
    I want to create a controller that depends on the class of a given instance of a model -(BaseController *)getControllerForModel:(Model *)model { BaseController *controller = nil; Class controllerClass = [BaseController class]; //the default value //find the right controller if ([model isMemberOfClass:[ModelClass1 class]]) controllerClass = [ConcreteController1 class]; else if ([model isMemberOfClass:[ModelClass2 class]]) controllerClass = [ConcreteController2 class]; else if ([model isMemberOfClass:[ModelClass3 class]]) controllerClass = [ConcreteController3 class]; ... else if ([model isMemberOfClass:[ModelClassX class]]) controllerClass = [ConcreteControllerX class]; else Trace(TRACELEVEL_WARNING, @"Unrecognized model type: %@", NSStringFromClass([model class])); //Now instantiate it with the model controller = [[[controllerClass alloc] initWithModel:model] autorelease]; return slotController; } I want to find a more flexible solution to this and thought of having a dictionary, which maps Model-Classes to Controller-Classes and then NSClassFromString could give me the right instance. My question is this: Is NSClassFromString using much of my applications performance if i use it several times (say, 100 times at once)? Or would it be about as fast as the above approach?

  • Getting Values from fetched Core Data

    - by user571905
    Hi there, Thanks to the wonderful people on this forum, I have overcome most of my Core Data woes. However one persists, and I'm certain it is a simple fix. I have a recipe app that parses an XML doc on load and puts the data in Core Data. Then I search that Core Data for particular recipes, ingredients, etc. Everything is working with one exception... I cannot do anything with the data I retrieve. For example, I search the core data for "eggplant" and get this at the end of the process: "<RecipeData: 0x6112a40> (entity: RecipeData; id: 0x6113880 <x-coredata:///RecipeData/tCDE9A0EE-DA3F-4BD0-AEF8-3C038586991D4> ; data: {\n ingredients = \"Eggplant|Cheese|Tomatoes|\";\n name = \"Eggplant Parm\";\n time = 40;\n})" How do I get the info out of there? I tried looping through, but that causes the app to crash: for (NSString* key in selectedRecipe) { id value = [selectedRecipe objectForKey:key]; NSLog(@"IN LOOP: %@", value); } Any suggestions? Thank you for your time.

  • Rewrite C++ code into Objective C

    - by Phil_M
    Hello I got some C++ Sourcecode that I would like to rewrite into Objective C. It would help me alot if someone could write me a header file for this Code.
