This is a small category on UIView that adds a few methods to aid in manual frame layout.
There are already a million libraries like this out there; I can't make a strong argument why mine's inherently better than any other.
Using Cocoapods:
pod "MWLayoutHelpers"
If you're not using CocoaPods, just drag the "Classes" folder into your project.
In general, there are two types of methods in here:
Shorthand accessors: Lets you avoid deeply introspecting into child properties. For example, to get the width of a view, instead of using someview.frame.size.width or CGRectGetWidth(someView) you can just use someView.width.
Shorthand setters: Lets you avoid creating throwaway instance variables to muck around with setting inner properties of a view's frame. If you just want to move a view while keeping its size, instead of doing this:
CGRect frame = someView.frame;
frame.origin = CGPointMake(0, 0);
someView.frame = frame;
You can just call:
someView.x = 0;
someView.y = 0;
Alternatively, you could also call [someView moveToPoint:CGPointZero];
For full usage, check out the UIView+MWLayoutHelpers.h header file.
