Making by background image dim when the keyboard is present in IOS 7

Hey guys and girls,

I am building a simple-ish login screen.

When the keyboard raises the text fields move up out the way so they can be seen when editing. but how do I make the imageView object darker when that happens so it does not interfere?

First, you have to set the tintColor property of your imageView to a color

imageView.tintColor = [UIColor darkGrayColor];

then, when the keyboard is visible, change the rendering mode of the image...

UIImage *theImage = [imageView.image imageWithRenderingMode:UIImageRenderingModeAlwaysTemplate];
imageView.image = theImage;

...and when the keyboard disappears, change it back to the original rendering mode

UIImage *theImage = [imageView.image imageWithRenderingMode:UIImageRenderingModeAlwaysOriginal];
imageView.image = theImage;
