  • Can't use method from class in other file

    - by user1833848
    I am not able to use one of my methods that i implemented in my tableviewcell file in my tableview controller implementation. I tried searching the web and xcode help with no luck. My codes looks like this: TableViewController.h: #import TableViewCell.h @interface TableViewController : UITableViewController @property (nonatomic, strong) IBOutlet UIBarButtonItem *A1Buy; @property (nonatomic, getter = isUserInteractionEnabled) BOOL userInteractionEnabled; - (IBAction)A1Buy:(UIBarButtonItem *)sender; TableViewController.m: @implementation A1ViewController @synthesize A1Buy = _A1Buy; @synthesize userInteractionEnabled; - (IBAction)A1Buy:(UIBarButtonItem *)sender { [TableViewCell Enable]; //this is where it gives an error } TableViewCell.h: @interface TableViewCell : UITableViewCell { BOOL Enable; BOOL Disable; } @property (nonatomic, getter = isUserInteractionEnabled) BOOL userInteractionEnabled; TableViewCell.m: @implementation TableViewCell; @synthesize userInteractionEnabled; - (BOOL) Enable { return userInteractionEnabled = YES; } - (BOOL) Disable { return userInteractionEnabled = NO; } As you can see i am trying to enable user interaction with a button, but Xcode only gives me errors like "class does not have this method" and stuff like that. All files are importet correctly so thats not why. Would appreciate any help. Thanks!

  • Working with Content Shell on windows 7

    - by JAre
    I can't run Content Shell on my system (Windows 7 x64): When i run --dump-render-tree with the stable release content_shell.exe crashes with message: [XXXX:XXXX:0522/XXXXXX:XXXXXXXXX:FATAL:content_main_runner.cc(735)] Check failed: base::i18n::InitializeICU() were X - some number. And i can't run dev build because it misses mojo_system.dll. Is there any way to fix it? Does it work on Linux or MacOS? If so i probably can run it in VM For the time being.

  • Moving UITableView row to top of list when selected

    - by Max Kilgore
    I am sure this is an easy thing to do. I am very new to objective C (picked up a job the boss was going to outsource) and could use all the help I can get. Just point me in the right direction here. Basically what I want to set up is this: I have a list of phone numbers that expands to as many rows as needed. I have no problem populating and the list works fine, but I would like for all of the recently selected items in the list to be more easily accessible at the top. So, whenever the user "didSelectRowAtIndexPath", I would like the row to move to the top. I just KNOW this is super simple... but I haven't found the solution yet. No hurry. I am just trying to figure things out on my own. Thanks in advance!

  • UIActionsSheet text shadow problem

    - by AlexVogel
    I have a problem with the text shadow of the UIActionSheet buttons. At iOS 4.0.2 long string were truncated automatically. No at iOS 4.2 these texts are presented with a smaller font. But now the offset of the shadow is corrupted and to big. Is there a possibility to change/remove the text shadow of the UIActionSheet. EDIT: I'm building the UIActionSheet not with initWithTitle:, but with the normal init and sets all needed properties afterwards because the number of possible buttons is dynamic and the texts cannot be change. I've tested it with initWithTitle: and got the same results.

  • 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.

  • UITextView refuses to change its color

    - by Friendlydeveloper
    Hello, in some cases things you'd expect to solve within a sec turn out to become a lifetime adventure. This is one of these cases :) All I wanted to do, is simply change the text color of one of my UITextViews. So far I tried: UIColor *myColor = [UIColor colorWithHue:38 saturation:98 brightness:100 alpha:1.0]; [myTextView setTextColor:myColor]; OR UIColor *myColor = [UIColor colorWithPatternImage:[UIImage imageNamed:@"colorImage.png"]]; [myTextView setTextColor:myColor]; Both seem to work fine for UILabels, but fail for UITextView elements. When I try [UIColor colorWithHue... I only get a reddish kinda color, no matter what values I choose (except values for black and white. They work). The colorWithPatternImage does not change textColor at all. Strange isn't it? I obviously must be missing something. Help is very much appreciated. Thanks in advance.

  • How many android apps are open source?

    - by Alex

  • Application HANGS UP if 3G connection is used (WiFi is OK)

    - by SkyEagle888
    Hi, My application uses the following codes to connect to web site and download a web page for processing. HttpURLConnection c = (HttpURLConnection) url.openConnection(); c.setRequestMethod("GET"); c.setRequestProperty("User-Agent", "Mozilla/3.0 (compatible; MSIE 4.0; Windows NT)"); c.setRequestProperty("Accept-Language", "zh-hk"); c.setRequestProperty("Connection", "Keep-Alive"); c.setConnectTimeout(6000); // mTimeout is in seconds intTries = 3; do { c.connect(); if (c.getResponseCode() == 200) { break; } else { intTries --; } } while (intTries > 0); The codes are run in main thread only. If WiFi is being used, it is nice and clean. If 3G connection is being used, sometimes, it cannot get connected OR application HANGS. Is there any significant difference between handling WiFi and 3G ? Thanks.

  • 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 is Core Data detecting the conflicts, actually?

    - by brainfrog
    Apple says about -detectConflictsForObject: If on the next invocation of save: object has been modified in its persistent store, the save fails. This allows optimistic locking for unchanged objects. Conflict detection is always performed on changed or deleted objects. So what does this mean? If I simply modify an managed object and then save the context, there is always a conflict detection happening? Does this conflict detection simply compare the timestamps of the "records" to see if the "new" data is actually "old"? Is that a conflict?

    scrollViewDidEndScrollingAnimation and scrollViewDidEndDecelerating Looks like the last one is called when the bouncing effect is finished. But can't really understand what's the difference between first because they are called same time(well, decelerating called first).
