  • Remove newline character while XML parsing

    - by Prashant
    Hi, I am facing a problem while XML parsing. I have an NSMutablestring currentElementValue that has newlines into it. It has been received as an XMl from a web source. Even when i am trying to remove newline charactersets of substring the first 3 char there is no effect on the string. What can be done here? Regards PC Code is (void)parser:(NSXMLParser *)parser foundCharacters:(NSString *)string { if(!currentElementValue) currentElementValue = [[NSMutableString alloc] initWithString:string]; else { [currentElementValue substringFromIndex:3]; [currentElementValue stringByTrimmingCharactersInSet:[NSCharacterSet newlineCharacterSet]]; NSLog(@"Processing Value : %@ with length %d", currentElementValue,[currentElementValue length] ); }

  • subversioning ipad app project

    - by MistakesRInevitable
    Hi All, I am currently looking at setting up an Ipad app project into subversion. Ive had a lot of experience with windows based development and .net. With this we have just created a repository in a network folder (by just right clicking - TortiseSVN - create repository) , than all we have done is our developers have checked out from this directory. How do we go about doing this in xcode. I know subversion is integrated with xcode and I am pretty confident of doing everything (from tutorials) except for the creation of the repository. Just wondering how we go about creating a repository in a folder based up on network folder? Thanks in advance

  • iPad search bar bad memory access?

    - by Geoff Baum
    Hello all, So I am trying to implement a search bar in my app and am very close but can't seem to figure out where this memory error is occurring. This is what part of my search method looks like: filters = [[NSMutableArray alloc] init]; NSString *searchText = detailSearch.text; NSMutableArray *searchArray = [[NSMutableArray alloc] init]; // Normally holds the object (ex: 70 locations) searchArray = self.copyOfFilters ; //This is the line that is breaking after ~2-3 letters are entered in the search for (NSString *sTemp in searchArray) { NSRange titleResultsRange = [sTemp rangeOfString:searchText options:NSCaseInsensitiveSearch]; if (titleResultsRange.length > 0) [filters addObject:sTemp]; } displayedFilters = filters; copyOfFilters is a deep copy of the displayed filters that appear when the view first loads via: self.copyOfFilters = [[NSMutableArray alloc] initWithArray:displayedFilters copyItems:YES]; I have traced through the entry of letters and it is accurate after 2 letters, but once you try and enter a letter after a space in the search bar, it crashes. The value of copyOfFilters = {(int)[$VAR count]} objects. Does anyone know what may be causing this? Thanks!

  • best way to use CoreLocation across multiple views

    - by Matt
    I have two views in my app, one is a general view where CoreLocation works away calculating the users location while the user is doing other stuff in the view. The second view is accessed by the user when they touch a button allowing them to locate themselves more accurately using a mapview and MapKit, i would like the mapview in this view to show the location that CoreLocation has already identified in the first view AND to continue displaying this location based on updates from CoreLocation in the other view. Is the best way here to create a singleton that encapsulates the CoreLocation stuff and have this referenced in the view with the map, or to use notifications ? or to use some other better practice for my scenario ? Thanks

  • How do I prevent my table cell's textview from being editable after editing is done?

    - by Gorgando
    So this is an interesting problem. I have custom tableviewcells that include a text field. When In my cellForRowAtIndexPath I have an if statement that determines whether or not the cell's text field should be editable- it looks like this: (self.isEditing) ? [infoCell.textField setEnabled:YES] : [infoCell.textField setEnabled:NO]; This actually works well - except for the issue I'm having. It makes it so that when the tableview is displayed, the rows' text field cannot be edited. When the user clicks "Edit" to put it into editing mode, then the text fields are enabled for editing. The Problem: When I am editing a field, and click "Done", it goes back to the regular tableview but the keyboard stays visible and the last cell's text field I was editing continues to be editable. What Should happen: The keyboard should go away and all the cells' text fields should no longer be editable. Any ideas about what could be going wrong? Things to look for? Thanks!

  • iOS Development: Can I store an array of integers in a Core Data object without creating a new table to represent the array?

    - by BeachRunnerJoe
    Hello. I'm using Core Data and I'm trying to figure out the simplest way to store an array of integers in one of my Core Data entities. Currently, my entities contain various arrays of objects that are more complex than a single number, so it makes sense to represent those arrays as tables in my DB and attach them using relationships. If I want to store a simple array of integers, do I need to create a new table with a single column and attach it using a one-to-many relationship? Or is there a more simple way? Thanks in advance for your wisdom!

  • multiple regionDidChangeAnimated calls - what gives?

    - by mvexel
    I have a MKMapView inside a UITableView as a custom cell (don't ask ;) - don't know if it matters really), for which I register a regionDidChangeAnimated delegate method. This method gets called three times when the UITableView is loaded - once with the actual region and then two more times with a region that is way off. In the simulator, I consistently get a region with center (+37.43997405, -97.03125000). On the device, it seems to depend on the location reported by the location manager, which initializes the map view. Why am I getting three regionDidChangeAnimated calls? And why are the center coordinates for the last two of them off? This is the code I use to get the center coordinates: - (void)mapView:(MKMapView *)mapView regionDidChangeAnimated:(BOOL)animated { CLLocation *l = [[CLLocation alloc] initWithLatitude:self.mapView.centerCoordinate.latitude longitude:self.mapView.centerCoordinate.longitude]; (....)

  • indentationLevel property doesn't appear to do anything?

    - by JoBu1324
    I'm have a number rows I'm inserting into a table using -insertRowsAtIndexPaths:withRowAnimation, and I would like the rows to be indented from the left to distinguish them from the rest of the cells. The indentationLevel property of UITableViewCell looks like it's exactly what I need, but it doesn't seem to do anything. Here's the code I'm using to set the indentation level (dot syntax doesn't make a difference): [cell setIndentationWidth:10]; [cell setIndentationLevel:1]; Is indentationLevel what I want, or should I be looking elsewhere?

  • Failure when adding images to a thumbnail gallery

    - by Martin KS
    morning all, I've been browsing around trying to work out what I've done wrong when trying to add a thumbnail to a gallery view, but can't work out what on earth it might be. I'm trying to use the following code to stick a thumbnail onto a blank view: UIImageView *any = [[UIImageView alloc] initWithFrame:CGRectMake(a,b,70,60)]; any.image = [UIImage imageNamed:selectedThumbPath]; any.tag = 0; [self.view addSubview:any]; In the above example: a = 165 b = 150 selectedThumbPath = the full path to a thumbnail ie. /users/Cleverbum/library etc I'm pulling my hair out, there are no error messages, and no clues as to why it's not drawing anything. What's worse is that this is one of the only parts of the code i've not changed!

  • What is the best way to properly test object equality against an array of objects?

    - by radesix
    My objective is to abort the NSXMLParser when I parse an item that already exists in cache. The basic flow of the program works like this: 1) Program starts and downloads an XML feed. Each item in the feed is represented by a custom object (FeedItem). Each FeedItem gets added to an array. 2) When the parsing is complete the contents of the array (all FeedItem objects) are archived to the disk. The next time the program is executed or the feed is refreshed by the user I begin parsing again; however, since a cache (array) now exists as each item is parsed I want to see if the object exists in the cache. If it does then I know I have downloaded all the new items and no longer need to continue parsing. What I am learning, I think, is that I can't use indexOfObject or indexOfObjectIDenticalTo: because these really seem to be checking to see that the objects are using the same memory address (thus identical). What I want to do is see if the contents of the object are equal (or at least some of the contents). I've done some research and found that I can override the IsEqual method; however, I really don't want to iterate/enumerate through the entire cache contents table for every newly parsed XML FeedItem. Is iterating through the collection and testing each one for equality the only way to do this or is there a better technique I am not aware of? Currently I am using the following code though I know it needs to change: NSUInteger index = [self.feedListCache.feedList indexOfObject:self.currentFeedItem]; if (index == NSNotFound) { }

  • Objective-C: Cannot Change Value of Instance Variable Inside a Function

    - by user262325
    Hello everyone, I cannot change the value of an instance variable inside a function. I have defined a class: // info.h #import <Foundation/Foundation.h> @interface NSMyObject : NSObject { NSInteger i; } -(void) setI:(NSInteger)v; @end #import "info.h" @implementation NSMyObject -(void) setI:(NSInteger)v ; { i=v; } - (void)dealloc { [super dealloc]; } @end I call a function 'myFunction' with parameter temObj which is a NSMyObject instance. myFunction(temObj);//temObj is NSMyObject In the function, I can change the value of the instance variable of parameter obj. -(void)myFunction:(NSMyObject*) obj; { [obj setI:0]; } ... expecting this to change the content of temObj. But when I check the results of operation on obj in function myFunction the value of temObj.i has not changed. Welcome any comment Thanks

  • EventKitUI view and edit problem!

    - by Alish
    I try to to find a solution to do View and Edit of a the item from a tablview. My application base on UITabBarController. Each of the Bar items contain a class with a a couple of UIViews. This is the first items of UITabBarController. I done Add event from Apple sample code: SimpleEKDemo. Add Event working without any problem. I tried to add View and Edit part to the code. I would able to select an items from tableView to edit the selected item. But after I tried to add code from SimpleEKDemo to my code, I realized I have to add UINavigationController to the implement. So I did. After I add that it's came to the items of UITabBarController. Also I even the Add Event didn't worked very well (I couldn't insert event name and location. but edit was working. So I need to know: 1- Is it possible to implement Edit/View without using UINavigationController. If yes please let me know a sample code. 2- If I must use UINavigationController. Because I don't need UINavigationController to become it the first page and I don't need any bar added to my application. Is it possible it's appear in the application when I choose a item of tableView but appear alike that! Snapshots: https://public.me.com/alish (pict.zip)

  • SQLite3 - select date range not working

    - by iFloh
    yet anotherone that gives me grief. In a SQLite3 DB Select I query for a date range specified in (NSDate *)fromDate to (NSDate *)toDate const char *sql = "SELECT * FROM A, B WHERE A.key = B.key AND A.date between ? and ?"; After opening the DB I run the query in Objective-C as follows: NSDateFormatter *tmpDatFmt = [[[NSDateFormatter alloc] init] autorelease]; [tmpDatFmt setDateFormat:@"dd-MM-yyyy"]; sqlite3_stmt *stmt; if(sqlite3_prepare_v2(db, sql, -1, &stmt, NULL) == SQLITE_OK) { NSLog(@"From %s to %s;", [[tmpDatFmt stringFromDate:fromDate] UTF8String], [[tmpDatFmt stringFromDate:toDate] UTF8String]); sqlite3_bind_text(stmt, 1, [[tmpDatFmt stringFromDate:fromDate] UTF8String], -1, SQLITE_STATIC); // first '?' sqlite3_bind_text(stmt, 2, [[tmpDatFmt stringFromDate:toDate] UTF8String], -1, SQLITE_STATIC); // second '?' while(sqlite3_step(stmt) == SQLITE_ROW) { NSLog(@"Success");} In the database I have several records that match the date range: 12-04-2010 = in seconds 1271059200 13-04-2010 = in seconds 1271145600 13-04-2010 = in seconds 1271152800 14-04-2010 = in seconds 1271267100 When I run it the first NSLog shows From 2010-04-01 to 2010-04-30 my problem is the records are not selected (no "Success" shows in the log) and I don't understand why. earlier I had miscalculated the dates 2 days later as 14-04-2010 = in seconds 1271232000 15-04-2010 = in seconds 1271318400 15-04-2010 = in seconds 1271325600 16-04-2010 = in seconds 1271439936 These dates worked fine (4 x "Success in the log). I am puzzled ...

  • Code formatting when using pointers

    - by HD-VRSCA
    Is there any reason why the asterisk is next to the object type in this code? I'm a little confused by the way I see this used. Some times it looks like this: NSString* stringBefore; and sometimes like this: NSString *stringBefore; Is there a difference? Or a right or wrong way to do this? Thanks
