ios - Property is nil after having been assigned -


the private property declared as:

@interface camera () {     se3 *_transformationfromworld; } @end

is assigned when camera object initialized:

self = [super init]; se3 *transformation = [[se3 alloc] initwithrotation:r withtranslation:t]; _transformationfromworld = transformation; [self initintrinsics];  return self;

but in debugger window can see remains nil, while transformation object assigned normally. (i expanded code check wasn't se3 initialization method returning nil)

how possible?

solution:

comments @shahar pointed me right direction. when declared property (always in .m file):

@interface camera () @property se3 *transformationfromworld; @end

it magically worked. care explain difference between way of declaring property , previous one?
