RestKit RKObjectMapping error, update from 0.10 to 0.20

Question

I'm updating RestKit from 0.10 to 0.20 and getting some errors I'm trying to figure out.

I'm getting errors on the Spring.m file for the MappingForClass:usingBlock, no @interface for mapKeyPathsToAttributes, and no @interface for hasMany:withMapping.

Can't seem to figure this out myself.

Spring.h

@interface Spring : NSObject

@property (nonatomic, strong) NSString *name;
@property (nonatomic, strong) NSNumber *id;
@property (nonatomic, strong) NSArray *leafs;

+ (RKObjectMapping *)mapping;

@end

Spring.m

@implementation Spring

// Creating RestKit object mapping variable, THIS IS WHERE ERRORS OCCUR
+ (RKObjectMapping *)mapping {
    RKObjectMapping *objectMapping = [RKObjectMapping mappingForClass:[self class] usingBlock:^(RKObjectMapping *mapping) {
       [mapping mapKeyPathsToAttributes:
            @"name", @"name",
            @"id", @"id",
            nil];
        [mapping hasMany:@"leafs" withMapping:[Leaf mapping]];
    }];

    return objectMapping;
}

@end

I'm using https://github.com/RestKit/RestKit/wiki/Upgrading-from-v0.10.x-to-v0.20.0 to help me try to figure this out.
