Tired of typing "CGRectMake" a million times for simple alignment stuff? Me too.
Here's an alignment category for UIView in iOS. See the .h file for method options and descriptions.
Align myView
to the far left of its superview, with a 10px margin:
[myView alignTo:UIViewAlignmentLeft margins:UIEdgeInsetsMake(0,10,0,0)];
Align myView
to the top-left of its superview:
[myView alignTo:(UIViewAlignmentTop | UIViewAlignmentLeft)];
Align myView
bottom & centered in the given rect:
[myView alignTo:(UIViewAlignmentCenterHorizontal | UIViewAlignmentBottom) ofRect:otherRect];
