  • Uitableview not able to hold data

    - by pankaj
    Hi i have a uitableview, i am displaying some data of about 200 rows in it. Data will be displayed in several sections which will be determined at run time. I am able to get sections but i am not able to display data for a particular section in correct order. I have data in the form of dictionaries in an array. My Code: - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { TeraGoAppDelegate *appDel = (TeraGoAppDelegate *)[[UIApplication sharedApplication] delegate]; UITableViewCell *cell = nil; if (cell == nil) { cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:nil] autorelease]; cell.textLabel.text = [(NSMutableDictionary *)[appDel.arrEqp objectAtIndex:countEqpIndex] objectForKey:@"EQP_NAME"]; cell.textLabel.font = [UIFont fontWithName:@"Arial" size:14]; if(![[(NSMutableDictionary *)[appDel.arrEqp objectAtIndex:indexPath.row] objectForKey:@"select"] isEqualToString:@"0"]) { cell.accessoryType = UITableViewCellAccessoryCheckmark; } else cell.accessoryType = UITableViewCellAccessoryNone; } // Set up the cell... return cell; } I am trying to use indexPath.row but its values initialises from 0 in every section I can not get data from array in this case as i dont have index of array to get data. How will i get the index of array whose values i need to display????

  • 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.

  • 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.

  • Push notification is successfully sent, but the device does not receive (occasionally)

    - by ashiina
    I have been having a problem where some devices will not receive a push notification, since yesterday. The certificate / devicetoken seem to be correct, since the device used to successfully receive push notifications until yesterday. On the server-side, there are no errors or connection refusals, and the push notification seems to be successfully sent every time. But still, there are many occasions where the device does not correctly receive the push. Some surrounding information: I am doing this on the production environment. No errors / connection refusals on the server-side I am sending the exactly same JSON everytime. 2 of our devices are not receiving the push notification AT ALL since yesterday 1 of our device receives push notifications at a lower success rate (about 70%) than yesterday 1~2 of our devices still receive push notifications successfully even now. All of the above devices were able to receive push notifications properly on the production environment until yesterday. There is no difference in the server-side result for when the push is successful, and when the device doesn't receive it... Therefore it is virtually impossible to identify the problem. This is the server-side PHP code I am using: $ctx = stream_context_create(); stream_context_set_option($ctx, 'ssl', 'local_cert', $this->apnsData[$development]['certificate']); $fp = stream_socket_client($this->apnsData[$development]['ssl'], $error, $errorString, 100, (STREAM_CLIENT_C ONNECT|STREAM_CLIENT_PERSISTENT), $ctx); if(!$fp){ $this->_pushFailed($pid); $this->_triggerError("Failed to connect to APNS: {$error} {$errorString}."); } else { $msg = chr(0).pack("n",32).pack('H*',$token).pack("n",strlen($message)).$message; $fwrite = fwrite($fp, $msg); if(!$fwrite) { error_log("[APNS] push failed..."); $this->_pushFailed($pid); $this->_triggerError("Failed writing to stream.", E_USER_ERROR); } else { error_log("[APNS] push successful! ::: $token -> $message ($fwrite bytes)"); } } fclose($fp); The log tells me that the push was successful (Cutting out the token for privacy) : [Wed Dec 12 11:42:00 2012] [error] [client 10.161.6.177] [APNS] push successful! ::: aa4f******44 -> {"aps":{"alert":{"body":"\\u300casdfasdf\\u300d","action-loc-key":"OK"},"badge":4,"sound":"chime"}} (134 bytes) Is there any way I can get help on this problem? Or is there anybody who is having the same problem?? Please help! I am getting complaints from some users on this....

  • Why I cant be able to change the UITableViewCell detailTextLabel's frame (just the label's position)?

    - by Simon
    Hi.. I am having a table view with default UITableViewCell of style UITableViewCellStyleValue2. I just want to move detailTextLabel few pixels to the right. I know it makes no sense to adjust its width and height :). I am trying to set detailTextLabel's frame with my x and y value. But its not affecting the its frame. I prefer to use default UITableViewCell, in this case, over a customized cell because the default UITableViewCell automatically manages the text alignment and centering of the labels.. How to change UITableViewCell detailTextLabel's frame? Am I allowed to change its frame? Thanks everyone..

  • Objective-C retain clarification

    - by Maverick
    I'm looking at this code: NSMutableArray *controllers = [[NSMutableArray alloc] init]; for (unsigned i = 0; i < kNumberOfPages; i++) { [controllers addObject:[NSNull null]]; } self.viewControllers = controllers; [controllers release]; Later on... - (void)dealloc { [viewControllers release]; ... } I see that self.viewControllers and controllers now point to the same allocated memory (of type NSMutableArray *), but when I call [controllers release] isn't self.viewControllers released as well, or is setting self.viewControllers = controllers automatically retains that memory?

  • Are there concurrency problems when using -performSelector:withObject:afterDelay: ?

    - by mystify
    For example, I often use this: [self performSelector:@selector(doSomethingAfterDelay:) withObject:someObject afterDelay:someDelay]; Now, lets say I call this 10 times to perform at the exact same delay, like: [self performSelector:@selector(doSomethingAfterDelay:) withObject:someObject afterDelay:2.0]; [self performSelector:@selector(doSomethingAfterDelay:) withObject:someObject afterDelay:2.0]; [self performSelector:@selector(doSomethingAfterDelay:) withObject:someObject afterDelay:2.0]; [self performSelector:@selector(doSomethingAfterDelay:) withObject:someObject afterDelay:2.0]; [self performSelector:@selector(doSomethingAfterDelay:) withObject:someObject afterDelay:2.0]; [self performSelector:@selector(doSomethingAfterDelay:) withObject:someObject afterDelay:2.0]; [self performSelector:@selector(doSomethingAfterDelay:) withObject:someObject afterDelay:2.0]; [self performSelector:@selector(doSomethingAfterDelay:) withObject:someObject afterDelay:2.0]; [self performSelector:@selector(doSomethingAfterDelay:) withObject:someObject afterDelay:2.0]; - (void)doSomethingAfterDelay:(id)someObject { /* access an array, read stuff, write stuff, do different things that would suffer in multithreaded environments .... all operations are nonatomic! */ } I have observed pretty strange behavior when doing things like this. For my understanding, this method schedules a timer to fire on the current thread, so in this case the main thread. But since it doesn't create new threads, it actually should not be possible to run into concurrency problems, right?

  • How to know when the user touches the OK button of the last StoreKit alert "Thank you. Your purchase

    - by Walchy
    I have integrated "In App Purchase" in a game to let the user unlock more levels. Everything works fine, but I have a little problem with the last alert "Thank You. Your purchase was successful. [OK]". My program gets informed that the transaction was successfully completed before this last alert pops up and so my game starts running again - then the alert comes up, annoying the user. I would like to wait with my game running until the user touches the "OK" button, but since it is an alert from StoreKit I have no idea when this happens or how I could catch it. I don't want to create another dialog (this time my own, therefor under my control) below the alert, just asking for touching "OK" again - would be a bad user experience. Anybody have any ideas?

  • living column in instruments

    - by dubbeat
    In the context of allocations what exactly does the living column mean? Does it mean the number of times an object was created or does it mean how many instances of an object there is? I ask because I'm testing going in and out of a view. When I enter the view I create a class "myClass". When I exit the view I nil "myClass" and release it. If I go in and out of the view 6 times for example the living column in instruments for "myClass" says 6. Is this normal or is it not being released properly?

  • Need help with text animation within UITableViewCell

    - by gdiphone
    I'm trying to implement a simple text animation in a custom UITableViewCell without having to go into editing mode which automatically brings up the delete button on the right. What I'm trying to accomplish is that when the label is updated by a button within the UITableviewcell, the text in the label is updated but with some smooth animation like sliding to the right since the updated text is prepended to the string. Any sample code would be great. thanks

    Hi, I'm getting the screenshots from the following code:- CGImageRef cgScreen = UIGetScreenImage(); if (cgScreen) { UIImage *result = [UIImage imageWithCGImage:cgScreen]; CGImageRelease(cgScreen); return result; } I'm calling the above code in a timer of 1/1.0 seconds as:- [array addObject:[UIImage imageWithScreenContents]]; where imagewithScreenContents is a function. But after some seconds i.e after adding 90 frames application crashes. I'm unable to understand the problem. Can somebody help me in solving the problem. Thanks in Adv.

  • 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.

  • iOS sdk question: how do I cast a UIView to a UIImage View (alternativly how do I get a UIImageView from a GestureRecognzer?)

    - by user439299
    Desired end result: user taps a UIImageView and the image changes to another image (a subsequent tap returns the image to the original state) Problem: I add a (unique) selector to a bunch of UIImageViews (in an array) and point the action at the same function - let's call this function imageTapped: for now. Here is my code so far: -(void)imageTapped:(UITapGestureRecognizer *)tapGesture { UIImageView *view = tapGesture.view; // rest of code... } This code actually works fine but gets a warning when I run it: "Incompatible objective c types initilizing 'struct UIView *', expected 'struct UIImageView *' Any way to get rid of this? Not sure how casting works in objective c... primitive types seem to work fine such as (int)someFloat works fine but (UIImageView)someUiView doesn't work. Like I said, code works alright when I run it but would like to get ride of the compiler warning. Any help would be awesome.... I am very new to objective c (or any non java language for that matter) so be gentle. Thanks in advance.

  • Optional Navigation Controller

    - by Kevin Sylvestre
    I have an application containing a variety of view controllers linked together in different ways (Welcome Browse Preview OR Browse Preview OR Settings Splash). The first view controller is presented modally using a navigation controller from a main controller, then the next set of view controllers are added using pop and push. This works correctly, but I need to be able to define my 'UINavigationBar' and 'UIToolbar' within interface builder, so they still work as expected if they are presented without using a navigation controller. Is this possible? Currently I get this if I try:
