  • Navigation Controller with Tab Bar only on first view

    - by dinoc
    I am seeking advice on how to start my project. I need to use a combination of the navigation controller and tabbar controller but on the second screen, I need the tabbar controller not to be there. Here is a brief description of the two main screens Screen 1 will have a tabbar controller with two tabs. The first tab is a tableview and when you tap on a table cell, it drills down to Screen 2. The second tab is just a filter view that updates the table in the first tab of Screen 1. Screen two is just a details screen from the cells of Screen 1. The catch is that I don't want the TabBar on Screen 2. I am struggling with how to get started. Do I start with a Navigation-based application since I need to be able to drill down? How do I just add a tab bar to the main screen of the navigation based app? I can't start with a Tab Bar application because if I load a navigation controller inside one of the views of the tab controller, then when I drill down inside the nav controller, the tab bar still stays on the next screen when I need it to go away. Any help would be appreciated.

  • How to navigate to a UITableView position by the cell it's title using indexing

    - by BarryK88
    I'm using a UITableView filled with a around 200 cells containing a title, subtitle and thumbnail image. I want to a have a selection method just like within the contact App from Apple where you can select a character from the alphabet. I'm at the point where I've drawn the selection interface (A,B,C etc), and via it's delegate I'm retrieving the respective index and title (i.e: A = 1, B = 2, C = 3 etc.). Now I want to navigate to the first cell, where the first character of the cell it's title is starting with the selected index character. Just like the contacts App. Can someone give me a direction for how to implement such functionality. - (NSInteger)tableView:(UITableView *)tableView sectionForSectionIndexTitle:(NSString *)title atIndex:(NSInteger)index I filled my sectionIndex by means of - (NSArray *)sectionIndexTitlesForTableView:(UITableView *)tableView { if(searching) return nil; NSMutableArray *tempArray = [[NSMutableArray alloc] init]; [tempArray addObject:@"A"]; [tempArray addObject:@"B"]; [tempArray addObject:@"C"]; [tempArray addObject:@"D"]; [tempArray addObject:@"E"]; [tempArray addObject:@"F"]; [tempArray addObject:@"G"]; [tempArray addObject:@"H"]; [tempArray addObject:@"I"]; [tempArray addObject:@"J"]; [tempArray addObject:@"K"]; [tempArray addObject:@"L"]; [tempArray addObject:@"M"]; [tempArray addObject:@"N"]; [tempArray addObject:@"O"]; [tempArray addObject:@"P"]; [tempArray addObject:@"Q"]; [tempArray addObject:@"R"]; [tempArray addObject:@"S"]; [tempArray addObject:@"T"]; [tempArray addObject:@"U"]; [tempArray addObject:@"V"]; [tempArray addObject:@"W"]; [tempArray addObject:@"X"]; [tempArray addObject:@"Y"]; [tempArray addObject:@"Z"]; return tempArray; }

  • 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!

  • Audio File continues to play even on leaving the view

    - by Swastik
    What I am doing is -(void)viewWillAppear:(BOOL)animated{ [NSTimer scheduledTimerWithTimeInterval:0.3 target:self selector:@selector(clickEvent:) userInfo:nil repeats:YES]; } -(void)clickEvent:(NSTimer *)aTimer{ NSDate* finishDate = [NSDate date]; if([finishDate timeIntervalSinceDate: self.startDate] 11 && touched == NO){ NSString *mp3Path = [[[NSBundle mainBundle] resourcePath] stringByAppendingPathComponent:@"test.mp3"]; [self playMusicFile:mp3Path]; NSLog(@"Timer from First Page"); [aTimer invalidate]; //[touchCheckTimer release]; aTimer = nil; } else{ } -(void)playMusicFile:(NSString *)mp3Path{ NSURL *mp3Url = [NSURL fileURLWithPath:mp3Path]; NSError *err; AVAudioPlayer *audPlayer = [[AVAudioPlayer alloc] initWithContentsOfURL:mp3Url error:&err]; [self setAudioPlayer1:audPlayer]; if(audioPlayer1) [audioPlayer1 play]; [audPlayer release]; } Now, on pushing another view this audio file keeps playing in the background. Please help!

  • Load all tab bar views when application first runs

    - by codenoobie
    Here's the problem. I have a tab bar controller with 4 separate views. When I navigate from the first view to the second view, it takes some time to load up the second view. What I want to do is be able to load and initialize all of my tab bar views during my splash screen. That way, when the user navigates between the tab views, there is no wait time. So the question is... how do I manually initialize my individual tab bar views in my app delegate? And once again, thank you stackoverflow!

  • create CLLocationCoordinate2D from array

    - by shani
    I have a plist with dictionary of array's with coordinates (stored as strings). I want to create a CLLocationCoordinate2D from every array and crate an overlay for the map. I did that - NSString *thePath = [[NSBundle mainBundle] pathForResource:@"Roots" ofType:@"plist"]; NSDictionary *pointsDic = [[NSDictionary alloc] initWithContentsOfFile:thePath]; NSArray *pointsArray = [NSArray arrayWithArray:[pointsDic objectForKey:@"roade1"]]; CLLocationCoordinate2D pointsToUse[256]; for(int i = 0; i < 256; i++) { CGPoint p = CGPointFromString([pointsArray objectAtIndex:i]); pointsToUse[i] = CLLocationCoordinate2DMake(p.x,p.y); NSLog(@"coord %f",pointsToUse [i].longitude); NSLog(@"coord %f",pointsToUse [i].latitude); } MKPolyline *myPolyline = [MKPolyline polylineWithCoordinates:pointsToUse count:256]; [[self mv] addOverlay:myPolyline]; but the app is crashing without any error. (BTW when i remove the addOverLay method the app does not crash). I have 2 questions- What am i doing wrong? I have tried to set the pointsArray count as the argument for the CLLocationCoordinate2D like that - CLLocationCoordinate2D pointsToUse[pointsArray count]; And i am getting an error. How can i set the CLLocationCoordinate2D dynamically ? Thanks for any help. Shani

    - by phx
    Hey all, i use some code for inline cell editing from Apples TaggedLocations Example and im now stuck. At the demo Code they save the changes at textFieldDidEndEditing, this works because they asume to edit only the first element in a table view. I have to edit every row at the table view, so my problem is how to get indexPath.row to update the correct object stored in a mutableArray. Or did i miss something? Thanks for your help!

  • Android/ iOS how to determine small changes in distance using sensors?

    - by Tom
    I have been doing a bit of research, but I cannot seem to find a way to determine small distances (centimeters and meters) using the sensors in Android or iOS devices. Bluetooth appears too inaccurate and require more than one device, GPS only works over larger variations in distance, and small variations in rotation seem to make using the accelerometer nearly impossible. Is there a method that I am unaware of that would allow me to do such a thing? I am familiar with Calculus, so using Integrals to determine distance based on changes in time and velocity/ acceleration is not a problem for me, I just do not know how to determine those things. Thank you.

  • Multiple peers connected.

    - by Ranbeuer
    I'm developing a game that requires up to four iPhones or iPod Touch to connect each other to play in turns. My question is, how can I accomplish this via GameKit. I've read that using client/server sessions is the way of doing it. But I can't find any examples that would illustrate this. Is it really possible to do it, or there can only be two devices connected at a time. I'd really appreciate if you all could help me with a code sample. Thanks.

  • Creation of model in core data on the fly

    - by user1740045
    How can we create a model in core data on the fly? I.e getting the schema of database from somewhere and then creating a Core Data Object graph? *QuesTion:* Yes thats fine, agreed with all the advantages. But, can anybody can tell practically, what is the benefit of integrating Core Data into project instead of using SQL directly. 1.No need to write SQL boiler plate code [but need to learn Core Data Model (steep curve)] 2.WE can undo and redo changes [but practically who needs it] 3.we can migrate to another schema [that can be done by SQLite as well jus need to add another field into table] 4.For say aggregation on some field in table,in Core Data we need to loop through Core Data Objects whereas in SQLite we need to first write SQLite Boiler Plate Code and then the basic aggregation SQL query,which is easy to write,only length of code will increase...But in case of Core Data (need to learn a lot). So apart from reducing the length of Code,does it actually adds value to project? or in terms of Memory Efficiency,Performance,etc.. PS: If anybody has actualy worked on Core Data(Model Creation On the Fly) , if possible share and gve pointers..thanks!

  • Is it possible to submit an update for an app on the AppStore without losing reviews?

    - by Frank Krueger
    Whenever I submit an update for me app, the number of reviews visible for it drops to 0. If the customer bothers to click through they can see the previous versions' reviews... But the damage has been done. Since the app has 0 stars, I see a significant drop in sales. It takes the app a good week of earning new reviews to restore sales. I usually version the app as 1.1, 1.2, 1.3 etc. Is there something I can do during the update process to prevent losing reviews like this?
