# uiEdgeInsets(for:)

Returns a UIKit edge insets structure based on the data in the specified string.

```
class func uiEdgeInsets(for string: String) -> UIEdgeInsets
```

## Parameters

`string`

A string whose contents are of the form “{*top*, *left*, *bottom*, *right*}”, where *top*, *left*, *bottom*, *right* are the floating-point component values of the <doc://com.apple.documentation/documentation/UIKit/UIEdgeInsets> structure. An example of a valid string is @”{3.0,8.0,3.0,5.0}”. The string is not localized, so items are always separated with a comma.

## Return Value

An edge insets data structure. If the string is not well-formed, the function returns <doc://com.apple.documentation/documentation/UIKit/UIEdgeInsets/zero>.

## Discussion

In general, you should use this function only to convert strings that were previously created using the [`string(for:)`](/documentation/Foundation/NSCoder/string(for:)-26b4z) function.
