按鈕不會禁用IOS目標C

Question

我正在編寫一個按鈕，當它被按下時發射彈丸。但是，我試圖禁用此按鈕，直到我希望它被使用。這是我的代碼，這是行不通的：

#import "GameViewController.h" 

@interface GameViewController() 

@end 

@implementation GameViewController 

//What happens when shoot button is pressed 

-(IBAction)Shoot:(id)sender{ 

    Shoot.enabled = NO; 

    //Step 1: upload image Step 2: Load image into image view Step 3: set coordinates and size 
    UIImage * Bulletimage= [UIImage imageNamed:@"bullet.png"]; 
    UIImageView * Bullet = [[UIImageView alloc] initWithImage:Bulletimage]; 
    [Bullet setFrame:CGRectMake(130,430,35,35)]; 
    [self.view addSubview:Bullet]; 

    //Creating Animation 
    [UIView animateWithDuration:0.7 delay:0 options: UIViewAnimationOptionAllowAnimatedContent animations:^{ [Bullet setFrame: 
                               CGRectMake (130, 20, 35, 35)];} 
        completion:^(BOOL finished) {Bullet.hidden = YES;}]; 

} 


//what happens when ready button is pressed 
-(IBAction)Ready:(id)sender{ 

    //button disapears 
    Ready.hidden = YES; 

} 

-(IBAction)Ready2:(id)sender{ 

    //button disapears 
    Ready2.hidden = YES; 

    if (Ready.hidden= YES, Ready2.hidden = YES) 
    { 
     //declaring images for animation 
     Countdown.animationImages = [NSArray arrayWithObjects: 
            [UIImage imageNamed:@"3.png"], 
            [UIImage imageNamed:@"2.png"], 
            [UIImage imageNamed:@"1.png"], 
            nil]; 

     [Countdown setAnimationRepeatCount:1]; 
     Countdown.AnimationDuration = 3; 
     [Countdown startAnimating]; 

     //end of loop 
     } 

} 


- (void)viewDidLoad { 
    [super viewDidLoad]; 
    // Do any additional setup after loading the view. 
} 

- (void)didReceiveMemoryWarning { 
    [super didReceiveMemoryWarning]; 
    // Dispose of any resources that can be recreated. 
} 

/* 
#pragma mark - Navigation 

// In a storyboard-based application, you will often want to do a little preparation before navigation 
- (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender { 
    // Get the new view controller using [segue destinationViewController]. 
    // Pass the selected object to the new view controller. 
} 
*/ 

@end

把Shoot.enabled = NO;到您的-()viewDidLoad功能。現在你不告訴按鈕被禁用，直到按鈕被按下。另外，你應該養成在Objective-C中不用大寫變量和函數名中第一個字的第一個字母的習慣，例如你可以命名字符串myString或函數-(void)buttonPressed。您通常只會使用類名稱的第一個詞，如MyCustomObject。
