Eu tenho um erro quando tentei criar um UIImageView. Veja este código:

UIImage* backgroundPanel = [[UIImage imageNamed:@"loginPanelBackground.png"] resizableImageWithCapInsets:UIEdgeInsetsMake(90, 0, 149, 416)];

self.connexionBackgroundImgView = [[UIImageView alloc] initWithImage:backgroundPanel];
self.connexionBackgroundImgView.frame = CGRectMake(0, 0, 416, 390); // THIS LINE PROVOC THE INVALID CONTEXT
[self.connexionView insertSubview:self.connexionBackgroundImgView aboveSubview:self.connexionToCreationCompteView];

Ele lança esse erro no log:
