## Important notes about PinLayout's Objective-c interface
#### `pinObjc` property
The PinLayout's objective-c interface is available using the property `pinObjc` (instead of `pin` in Swift)
```
[[view.pinObjc top] layout];
```
#### `layout()`
**Method:**
* **`layout()`**
When using the Objective-c interface, the `layout` method must be called explicitly to complete the view's layout. The method will execute PinLayout commands immediately. In Swift, PinLayout executes this method implicitly, it is not necessary to call it.
```
// Swift
view.pin.width(100)
// Objective-c
[[view.pinObjc width:100] layout];
```
