I'm trying to use the FXlabel when following this (Adding a gradient label section) tutorial. This is some of the code inside my viewDidLoad method:

self.logoLabel = [[FXLabel alloc] initWithFrame:CGRectMake(14, 11, 280, 87)];

[logoLabel setFont:[UIFont boldSystemFontOfSize:45]];

[logoLabel setTextColor:[UIColor whiteColor]];
[logoLabel setShadowColor:[UIColor blackColor]];
[logoLabel setShadowOffset:CGSizeMake(0, 2)];
[logoLabel setTextAlignment:UITextAlignmentCenter];
[logoLabel setBackgroundColor:[UIColor clearColor]];
[logoLabel setText:@"Attorney Biz"];

[logoLabel setGradientStartColor:[UIColor colorWithRed:163.0/255 green:203.0/255 blue:222.0/255 alpha:1.0]];
[logoLabel setGradientEndColor:[UIColor whiteColor]];

Unfortnuately, I get an error "No visible @interface for 'UILabel' declares the selector 'setGradientStartColor'" at the second-to-last line and "No visible @interface for 'UILabel' declares the selector 'setGradientEndColor'"

Can somebody explain how to remove these errors?
