I am still pretty new to objective-c and I am doing a finale project for my class. What i want to do is read from NSUserDefaults the array of 3 high scores and display them on the first screen.
Here is my code
self.backgroundColor = [SKColor colorWithRed:0.15 green:0.15 blue:0.3 alpha:1.0];
NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults];
NSArray *highscores = [[NSArray alloc] initWithArray:[defaults arrayForKey:@"highscores"]];
SKLabelNode *myLabel = [SKLabelNode labelNodeWithFontNamed:@"Chalkduster"];
myLabel.text = @"High Scores \n 1)%f \n 2)%f \n 3) %f",highscores(0),highscores(1),highscores(2); //error on this line
myLabel.fontSize = 30;
myLabel.position = CGPointMake(CGRectGetMidX(self.frame),
CGRectGetMidY(self.frame));
[self addChild:myLabel];
when i try to pass the highscores i get a error that NSArrays are not functions or function points
Edit the line of error with this line,
myLabel.text = [NSString stringWithFormat:@"High Scores \n 1)%f \n 2)%f \n 3) %f",
[[highscores objectAtIndex:0] floatValue],
[[highscores objectAtIndex:1] floatValue],
[[highscores objectAtIndex:2] floatValue]];
replace line
myLabel.text = @"High Scores \n 1)%f \n 2)%f \n 3) %f",highscores(0),highscores(1),highscores(2);
with
myLabel.text = @"High Scores \n 1)%f \n 2)%f \n 3) %f",[highscores objectAtIndex:0],[highscores objectAtIndex:1],[highscores objectAtIndex:2];
Hope this will solve the problem.
Try bellow code .......
self.backgroundColor = [SKColor colorWithRed:0.15 green:0.15 blue:0.3 alpha:1.0];
NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults];
NSArray *highscores = [[NSArray alloc] initWithArray:[defaults arrayForKey:@"highscores"]];
highscores = [highscores sortedArrayUsingComparator:
^NSComparisonResult(id obj1, id obj2) {
if ([obj1 intValue] < [obj2 intValue]) {
return NSOrderedAscending;
} else if ([obj1 intValue] > [obj2 intValue]) {
return NSOrderedDescending;
} else {
return NSOrderedSame;
}
}];
SKLabelNode *myLabel = [SKLabelNode labelNodeWithFontNamed:@"Chalkduster"];
myLabel.text = @"High Scores \n 1)%f \n 2)%f \n 3) %f",highscores(0),highscores(1),highscores(2); //error on this line
myLabel.fontSize = 30;
myLabel.position = CGPointMake(CGRectGetMidX(self.frame),
CGRectGetMidY(self.frame));
[self addChild:myLabel];
