Answer 1

You can use the method

- (UIImage *)resizableImageWithCapInsets:(UIEdgeInsets)capInsets resizingMode:(UIImageResizingMode)resizingMode;

capInsets is a specific area(e.g. UIEdgeInsetsMake(10, 18, 10, 18)), resizingMode should select UIImageResizingModeStretch .

UIImage *image = [[UIImage imageNamed:@"bubble.png"] resizableImageWithCapInsets:UIEdgeInsetsMake(10, 18, 10, 18) resizingMode:UIImageResizingModeStretch];
bubbleImageView.image = image;
