Type Method

imageWithData:scale:

Creates and returns an image object that uses the specified image data and scale factor.

Declaration

+ (UIImage *)imageWithData:(NSData *)data scale:(CGFloat)scale;

Parameters

data

The image data. This can be data from a file or data you create programmatically.

scale

The scale factor to use when interpreting the image data. Specifying a scale factor of 1.0 results in an image whose size matches the pixel-based dimensions of the image. Applying a different scale factor changes the size of the image as reported by the size property.

Return Value

A new image object for the specified data, or nil if the method could not initialize the image from the specified data.

Discussion

This method does not cache the image object.
