Property cannot be found on forward class object?

Question

I have a UIView and I\'m trying to set its layer properties.

self.colorSwatch = [[UIView alloc] initWithFrame:CGRectMake(400, 150, 100, 100)];
self.colorSwat         


        

Answer 1

It doesn't know what type of object the layer property is. Add #import <QuartzCore/QuartzCore.h> to the top of your file.

Answer 2

You need to import the file #import < QuartzCore/QuartzCore.h> in ViewController.m class if and only if xcode version is less than 5.

See if you are using xcode version 5 or latest than that then not required to import .It is automatically included.
