Titanium SDK UI/UX patterns and components expert. Use when working with, reviewing, analyzing, or examining Titanium layouts, ListView/TableView performance optimization, event handling and bubbling, gestures (swipe, pinch), animations, accessibility (VoiceOver/TalkBack), orientation changes, custom fonts/icons, app icons/splash screens, or platform-specific UI (Action Bar, Navigation Bar).

Titanium SDK UI expert

A practical guide to Titanium SDK UI. Covers layouts, event handling, animations, performance, and platform-specific components for iOS and Android.

Project detection

:::info auto-detects titanium projects This skill detects Titanium projects and provides UI guidance.

Detection happens automatically. You do not need to run a command.

Titanium project indicator:

```
tiapp.xml
```
(required for all Titanium projects)

Applicable to both:

Alloy projects (app/ folder structure)
Classic projects (Resources/ folder)

Behavior based on detection:

Titanium detected: Provide UI guidance for Alloy and Classic, ListView/TableView patterns, and platform differences
Not detected: State this is for Titanium projects only and skip UI guidance :::

Critical rules

Performance

Do not use
```
Ti.UI.SIZE
```
in ListViews. It causes jerky scrolling. Use fixed heights.
Prefer ListView over TableView for new apps with large datasets.
Batch updates with
```
applyProperties
```
to reduce bridge overhead.
Avoid WebView inside TableView. It kills scrolling performance.

iOS accessibility

Do not set accessibility properties on container views. It blocks child interaction.
Do not set
```
accessibilityLabel
```
on text controls on Android. It overrides visible text.

Layout

Use
```
dp
```
units for cross-platform consistency.
Android ScrollView is vertical or horizontal, not both. Set
```
scrollType
```
.

Platform-specific properties

:::danger critical: platform-specific properties require modifiers Using

Ti.UI.iOS.*

or

Ti.UI.Android.*

properties without platform modifiers will crash cross-platform compilation.

Example of the damage:

javascript

// Wrong: adds Ti.UI.iOS to an Android build
const win = Ti.UI.createWindow({
  statusBarStyle: Ti.UI.iOS.StatusBar.LIGHT_CONTENT
})

Correct approaches:

Option 1: TSS modifier (Alloy projects):

tss

"#mainWindow[platform=ios]": {
  statusBarStyle: Ti.UI.iOS.StatusBar.LIGHT_CONTENT
}

Option 2: Conditional code:

javascript

if (OS_IOS) {
  $.mainWindow.statusBarStyle = Ti.UI.iOS.StatusBar.LIGHT_CONTENT
}

Properties that always require platform modifiers:

iOS:

statusBarStyle

,

modalStyle

,

modalTransitionStyle

, any

Ti.UI.iOS.*

Android:
```
actionBar
```
config, any
```
Ti.UI.Android.*
```
constant

For platform-specific UI patterns, see platform-ui-ios.md and platform-ui-android.md. :::

Event management

Remove global listeners (
```
Ti.App
```
,
```
Ti.Gesture
```
,
```
Ti.Accelerometer
```
) on pause to save battery.
Input events bubble up. System events do not.

App architecture

Limit tabs to 4 or fewer for better UX across platforms.
Use NavigationWindow for iOS hierarchical navigation.
Handle
```
androidback
```
to prevent unexpected exits.

Platform differences summary

Feature	iOS	Android
3D Matrix	Full support	No support
Pinch gesture	Full support	Limited
ScrollView	Bidirectional	Unidirectional
TableView	Full support	Full support
ListView	Full support	Full support
Default template image	Left side	Right side
ListView action items	Swipe actions	No
Modal windows	Fills screen, covers tab bar	No effect (always full)
Navigation pattern	NavigationWindow	Back button + Menu

UI design workflow

Choose app structure: tab-based or window-based
Pick a layout mode: composite, vertical, or horizontal
Decide sizing:
```
SIZE
```
or
```
FILL
```
based on component defaults
Plan events: bubbling, app-level events, lifecycle
Optimize performance: templates, batch updates
Apply accessibility per platform
Add motion: animations, 2D/3D transforms, transitions
