locationManager didUpdateToLocation FromLocation 
     - (void)locationManager:(CLLocationManager *)manager 
    didUpdateToLocation:(CLLocation *)newLocation 
    fromLocation:(CLLocation *)oldLocation { 
     NSLog(@"%@", newLocation); 
     self.speedView.text = [[NSString stringWithFormat:@"%d", (speedCount) 
    I Receive the error on this line [newLocation speed]]; 

     } 

Answer 1

讓我們來看看你的代碼：

- (void)locationManager:(CLLocationManager *)manager 
     didUpdateToLocation:(CLLocation *)newLocation 
     fromLocation:(CLLocation *)oldLocation 
{ 
    NSLog(@"%@", newLocation); 
    self.speedView.text = [[NSString stringWithFormat:@"%d", (speedCount) 
    [newLocation speed]]; 
} 

好吧，你可以看到，與self.speedView.text盯着行不以分號結束，它也沒有一個方形支架終止stringWithFormat通話，它有一個額外的方括號。

你可能打算這樣做：

self.speedView.text = [NSString stringWithFormat:@"%d %f", speedCount, [newLocation speed]]; //Show both speedCount and speed in your text view(?) 

OR：

self.speedView.text = [NSString stringWithFormat:@"%f", [newLocation speed]]; //Show only speed
