IOS development tutorial -- How to Use the image at, ios --

Prepare an image in advance:

UIImage * image = [UIImageimageNamed: @ "red.png"];

This can be used before iOS 5.0:

NSInteger leftCapWidth = image. size. width * 0.5f;

NSInteger topCapHeight = image. size. height * 0.5f;

Image = [image stretchableImageWithLeftCapWidth: leftCapWidthtopCapHeight: topCapHeight];

In iOS 5.0, this can be used as follows:

CGFloat top = 8; // height of top Cover

CGFloat bottom = 8; // End Cover height

CGFloat left = 8; // width of the left End Cover

CGFloat right = 8; // right End Cover width

UIEdgeInsets insets = UIEdgeInsetsMake (top, left, bottom, right );

// Assign a value after scaling

Image = [image resizableImageWithCapInsets: insets];

This can be used in iOS6.0:

CGFloat top = 12; // height of top Cover

CGFloat bottom = 12; // End Cover height

CGFloat left = 10; // width of the left End Cover

CGFloat right = 10; // right End Cover width

UIEdgeInsets insets = UIEdgeInsetsMake (top, left, bottom, right );

// Specify the stretch mode and assign a value after scaling.

Image = [image resizableImageWithCapInsets: insetsresizingMode: UIImageResizingModeStretch];
