I created a UICollectionView using CSStickyHeaderFlowLayout, because i wanted to have separate Header for UICollectionView and its sections. It is showing data successfully, but when i scroll up or down and as soon as it touches to top or bottom boundary it crashes, giving following error, I simply want separate Headers for collection view and its sections like we have in UITableView. If someone can help resolve this issue or point some alternative.

I'm trying to change the picker rows after the window was loaded. The picker was created in the xml file but when a row was attempted to be added to it an error is thrown (see below).
How do i add the picker rows once the picker is already added?
view.xml
<!-- other parent views above -->
<Picker id="languagePicker" selectionIndicator="true" useSpinner="true"
width="Ti.Platform.displayCaps.platformWidth" right="0">
</Picker>
view.js
var languages = db.execute("SELECT * FROM language");
while(languages.isValidRow()){
$.languagePicker.add(Ti.UI.createPickerRow({title:languages.fieldByName('language')}));
languages.next();
}

The picker.add() method expects an array of PickerRow objects. This works in my app:
var data = [],
picker = Ti.UI.createPicker();
data.push(
Ti.UI.createPickerRow({
title: 'Row 1'
}));
data.push(
Ti.UI.createPickerRow({
title: 'Row2'
}));
picker.add(data);
See http://docs.appcelerator.com/platform/latest/#!/api/Titanium.UI.Picker-method-add

Please check if your root view controller UIViewController connections are intact. It usually happens due to broken link on the Interface Builder. If you are using Storyboards, make sure you haven't hooked up duplicate referencing outlets. Also ensure that you are importing AppDelegate.h.
Again there could be n number of reason for this crash. Please use exception or symbolic break point to come to a conclusion.
I'm trying to add UITableViewController to Today Widget, but every time I drag UITableViewController to Storyboard and run the Widget it crashes with the following error.
I've tried multiple times. I've tried it by using Table View object, but problem persists.
Note: It crashes even before loading viewDidLoad() method.

When you delete the default layout and drag a new table view controller, you need to mark the new view controller as 'Intial View Controller'
Here's the Apple's document which explains how to do it. https://developer.apple.com/library/ios/recipes/xcode_help-IB_storyboard/chapters/SetInitialController.html
In the storyboard, if you are using a custom view controller class made in swift, make sure you check the box 'Inherit Module From Target':
I've been stuck on this all day, and struggling to identify the source of a NSRangeException crash.
The app builds fine, but in the process of loading the first scene it throws:

It's a large app, and I cannot identify which objectAtIndex is causing the issue.
After looking at similar issues, I added an Exception breakpoint:
However the breakpoint just keeps taking me back to the main.m file:
int main(int argc, char * argv[]) {
#autoreleasepool {
return UIApplicationMain(argc, argv, nil, NSStringFromClass([AppDelegate class]));
}
Can anyone point me towards how I can identify the line that is causing this exception?
Thanks!
Edit:
When I click on the My360 icon at the top of the debugging console, it shows this:
I am new to Xcode and I keep getting this error and I am not quite sure what it means and how to fix it:

Thank you to all who help in advance!
The error says you are missing reuseIdentifier. For this,
just select tableViewCell in yourTableView in Storyboard and set reuseIdentifier in attributes Inspector.
use that reuse identifier in cellForRowAtIndex method as
[tableView dequeueReusableCellWithIdentifier:#"xxxx"]
