I just started my first project in iOS, recently I have encountered a problem in the UI when i receive it from the designer.
The expected output is shown as below and i can do most of it without any problem.
Now the problem came when I am about to implement this :
As the number of colour varies depending on item, I cannot add it like what I did for the share and love button I have no idea how can i implement something like this, I have look through the Object Library in the storyboard and cannot find any that can produce the output as expected .Any helps and guides are much apprecited!

When I go to type a message into my JSQMessagesViewController, the view is not being pushed up when the keyboard appears.
I can't send a message and I can't see the message I'm typing.
I don't even see any code in my VC that would be causing this / that would have changed this so I don't know where to start looking or what code to supply. I've downloaded examples using JSQMessages and I feel like this is just built in functionality behind the scenes.
Any ideas?
If you have viewDidAppear/viewDidDissapear being used you have to use
super.viewDidAppear(true)
and
super.viewDidDissapear(true)
also called respectively.
Adding those in fixed the issue.
I've got a TableViewController with static table; one of it's cells houses an UIView named graphArea. The view renders a chart, it's background and an axis line - all inside it's drawRect(). There are also two another views (sunView & markerView), that are made with Interface Builder and used for chart dynamics (moving marker line and point on touch events).
All worked buttery smooth until I've implemented and tried to test a share button, that employs the ordinary activityViewController mechanism.
The magic begins, when one from a couple of share activities, whose share plugin window takes the full screen, is finished (no matter whether sharing succeeded or cancelled). The app crashes.
Discovery using debugger made apparent to me, that the crash happens, because some views, including graphArea, sunView, markerView are nil after return from sharing screen.
Only some of fullscreen share plugins (like preinstalled Mail and Messages, or, in my case, "Download to DropBox" action) lead app to crash. Other fullscreen share plugins do not (tested Telegram, WhatsApp, Skype). No one of those non-fullscreen plugins has ever caused crash (Evernote, Twitter, 2Do etc.).
It looks like graphArea, sunView, markerView are deallocated from memory when "malicious" share plugins take full screen. I haven't figured out, why.
Here's some debug info:
The traceback and assembly of fatalErrorMessage.
The next screenshot shows a part of controller code and properties, that are nil on return from share plugin (gray selection). And yes, they were all non-nil before.
Please, help me! Thank you in advance!
Thank you, Palpatim. My friend also pointed me at the same thing: I've put graphArea.removeFromSuperview() in viewDidDisappear(), and this caused the exception after share plugins, that have .presentationStyle = fullScreen. So at the point, when the app is to show again, there is no more graphArea in on the tableView.
I need to show error message as a tooltip in iOS 8 but i don't know how to do it. What I want is something similar to the one shown in below image (I'm referring to the tooltip with messages Select and Select All):
There is a great collection of libraries which already target your problem.
For example have a look at: AMPopTip.
Then you could show the popover like:
self.popTip = [AMPopTip popTip];
[self.popTip showText:errorMessage direction:AMPopTipDirectionUp maxWidth:200 inView:self.view fromFrame:textField.frame];
and hide it:
[self.popTip hide];
Have a look at the github repo there are more examples for customizing this control.
You can find more which might suit your needs better here: cocoacontrols.com
I had a similar problem and wrote my own custom tooltip.
You can init with your custom view (i assume you write some delegations to detect actions within.) and present from anywhere.
Maybe not the best replacement of UIPopoverController but still works great. And a lifesaver for iPhone. Also highly customisable.

Hope this helps.
It seems all codes inside fx:Script blocks are black with no highlights. That's pretty inconvenient. Can anyone please let me know how to turn it on? Thanks!
First check that the active perspective is "Flash".
Then Window->Preferences. On the left side of the window expand Flash Builder->Editors->Syntax Coloring. On the right side you can set the colors for ActionsScript, CSS and MXML.
If after tinkering around you cannot fix the problem try to delete the "Adobe Flash Builder 4.5" folder located in the user's folder.
Hope this helps
Problem solved. I was using two different namespaces in Application and Module. It's "adobe.com/2006/mxml"; in mx:Application and "library://ns.adobe.com/flex/mx" in mx:Module. After the namespace in mx:Application was made consistent with the one from mx:Module, all syntax are highlighted correctly.
I'm currently playing with a bar chart implemented through Open Flash Charts (I believe version 1, might be version 2...) with PHP. Unfortunately, we're having real trouble with the tooltip not showing the correct thing. I am trying to get it to show the x-axis label for the hovered-over column, then a ":", then the value of the bar. The code is as follows:
$Colour = '#3465A4';
$BarChart= new bar();
$BarChart->set_values($Bar);
$BarChart->set_colour($Colour);
$BarChart->set_tooltip('#x_label#:#val#');
$x_labels = new x_axis_labels();
$x_labels->set_labels($Roles);
$x_labels->rotate(-60);
$x = new x_axis();
$x->set_labels($x_labels);
$chart = new open_flash_chart();
$chart->add_element($BarChart);
$chart->set_bg_colour( '#FFFFFF' );
$chart->set_x_axis($x);
$tooltip = new tooltip();
$tooltip->set_hover();
$chart->set_tooltip($tooltip);
$JSONArray['my_chart_1'] = $chart->toPrettyString();
As far as I can tell, this should be correct - the bar chart appears, with the correct values (populated from $bar, whose generation is not shown above). However, the hover-over tool-tip for a column only shows ":value" - the label name is missing!
Does anyone know where we might have gone wrong, and how I can fix it?
EDIT:
An update for any Bounty Hunters coming in to try and answer this question. The reason I have not accepted the below answer is that it only provides a work-around, and does not explain why the work-around is necessary. I am looking either for an answer to my original question (how to make the labels show in a normal bar-chart), or a reasonable explanation regarding why one must use a stacked bar chart (including sources makes your answer so much better!). If the latter, example code or an explanation of how stacked charts are created would be much appreciated as well!
If you are happy with the simple bar visuals then use stacked bar (using it with an array of one element will draw it just like the simple bar). That one will replace #x_label# correctly.
Alternatively you can copy the missing code from Bars/Stack.as to other bar types and recompile the code.
As per: http://forums.openflashchart.com/viewtopic.php?p=7433#p7433
It's a bug in OFC2 in the latest versions (at least). I've found what is causing the issue with #x_label#, but my understanding of the code/Flash isn't good enough to know why it's happened/broken.
I've done a quick fix that I need to test some more, but it now works on bar charts. Assuming I've not broken anything else beyond repair, it'll make it's way into the next community release.
If anyone wants the source code changes before the next release let me know.
(I am currently maintaining the community releases)
