868 PointsExpected Identifier in Xcode 6.1
When I write the code under #pragma mark - Prediciton
- (void) makePrediction {
[self.backgroundImageView.startAnimating];
self.predictionLabel.text = [self.crystalBall randomPrediction];
}
Xcode 6.1 gives me a "build failed" message, and a error "! Expected Identifier" on the startAnimating. When I read the documentation it says starAnimating is written in the form
- (void) startAnimating
So, what am I doing wrong??? it works for Amit!?

47,913 PointsWhat you're doing wrong is you're still using dot notation in the first line of code you gave. Your makePrediction method should look something like this:
- (void) makePrediction {
//Notice how there's no period between "self.backgroundImageView" and "startAnimating"
[self.backgroundImageView startAnimating];
self.predictionLabel.text = [self.crystalBall randomPrediction];
}
In Objective-C you call methods between square brackets by writing the object you want to call the method on first, then a space, then the method after that, like this:
[object method];
