Expected identifier on if (UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPhone) - ios

Question

*This is the whole code :)
I have been trying to fix this for an hour now, but i can still not make it.
I would be happy if someone could help me :)
Still can't make the UI_USER_INTERFACE_IDIOM code work.*
#import "ViewController.h"
#interface ViewController ()
#end
#implementation ViewController
-(void)Collision{
if (CGRectIntersectsRect(Heli.frame, Obstacle.frame)) {
[self EndGame];
}
if (CGRectIntersectsRect(Heli.frame, Obstacle2.frame)) {
[self EndGame];
}
if (CGRectIntersectsRect(Heli.frame, Bottom1.frame)) {
[self EndGame];
}
if (CGRectIntersectsRect(Heli.frame, Top1.frame)) {
[self EndGame];
}
}
-(void)EndGame{
if (Scorenumber > HighScore) {
HighScore = Scorenumber;
[[NSUserDefaults standardUserDefaults] setInteger:HighScore
forKey:#"HighScoreSaved"];
}
Heli.hidden = YES;
[timer invalidate];
[Scorer invalidate];
[self performSelector:#selector(NewGame) withObject: nil afterDelay:2];
}
-(void)NewGame{
if (UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPhone) {
// For iPhone
Bottom1.hidden = YES;
Top1.hidden = YES;
Obstacle.hidden = YES;
Obstacle2.hidden = YES;
corona.hidden = YES;
Intro1.hidden = NO;
Intro2.hidden = NO;
Intro3.hidden = NO;
Heli.hidden = NO;
Heli.center = CGPointMake(88, 286);
Heli.image = [UIImage imageNamed:#"buss til app opp.png"];
Start = YES;
Scorenumber = 0;
Score.text = [NSString stringWithFormat:#"Score: 0"];
Intro3.text = [NSString stringWithFormat:#"HighScore: %i", HighScore];
}
} else{
// For iPad
Bottom1.hidden = YES;
Top1.hidden = YES;
Obstacle.hidden = YES;
Obstacle2.hidden = YES;
corona.hidden = YES;
Intro1.hidden = NO;
Intro2.hidden = NO;
Intro3.hidden = NO;
Heli.hidden = NO;
Heli.center = CGPointMake(153, 515);
Heli.image = [UIImage imageNamed:#"buss til app opp.png"];
Start = YES;
Scorenumber = 0;
Score.text = [NSString stringWithFormat:#"Score: 0"];
Intro3.text = [NSString stringWithFormat:#"HighScore: %i", HighScore];

Answer 1

Just look at following code:
-(void)NewGame{
if (UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPhone) {
// For iPhone
Bottom1.hidden = YES;
Top1.hidden = YES;
Obstacle.hidden = YES;
Obstacle2.hidden = YES;
corona.hidden = YES;
Intro1.hidden = NO;
Intro2.hidden = NO;
Intro3.hidden = NO;
Heli.hidden = NO;
Heli.center = CGPointMake(88, 286);
Heli.image = [UIImage imageNamed:#"buss til app opp.png"];
Start = YES;
Scorenumber = 0;
Score.text = [NSString stringWithFormat:#"Score: 0"];
Intro3.text = [NSString stringWithFormat:#"HighScore: %i", HighScore];
}
} else{
and see - "}" symbol on line before "} else{" is wrong. It is the pair for
if (UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPhone) {
opening construction, so "else" is "standalone - it is wrong.
Try to delete this "}".
