在实现上下文中缺少@end [英] @end missing in implementation context

问题描述

我没有足够的声誉来发布图片..因此希望您能够为我提供帮助.在第三行显示"@implementation viewcontroller"的地方，我的xcode告诉我此"@end在实现上下文中丢失" 预先感谢！

I do not have enough reputation to post an image.. so hopefully you will be able to help me through this. on the third line where is says "@implementation viewcontroller" my xcode is telling me this "@end is missing in implementation context" thanks in advance!

@interface ViewController ()
@end

@implementation ViewController

- (void)viewDidLoad {
    mainInt = 0;
    randomMain = [NSTimer scheduledTimerWithTimeInterval:(1.0/1.0) target:self selector:@selector(randomMainvoid) userInfo:nil repeats:YES];
}


- (void)randomMainvoid {
    mainInt +=1;
    label.text = [NSString stringWithFormat:@"%d", mainInt];       
}    


- (IBAction)Start {
    [startButton setHidden:YES];
    timer = [NSTimer scheduledTimerWithTimeInterval:(0.0088) target:self selector:@selector(onTimer) userInfo:nil repeats:YES];
    pos = CGPointMake(5.0, 6.0);
}

推荐答案

在@implementation ViewController的末尾，您需要@end

您的.m应该如下所示:

Your .m should look like this:

@interface ViewController ()
@end

@implementation ViewController

- (void)viewDidLoad {
    mainInt = 0;
    randomMain = [NSTimer scheduledTimerWithTimeInterval:(1.0/1.0) target:self selector:@selector(randomMainvoid) userInfo:nil repeats:YES];
}


- (void)randomMainvoid {
    mainInt +=1;
    label.text = [NSString stringWithFormat:@"%d", mainInt];       
}    


- (IBAction)Start {
    [startButton setHidden:YES];
    timer = [NSTimer scheduledTimerWithTimeInterval:(0.0088) target:self selector:@selector(onTimer) userInfo:nil repeats:YES];
    pos = CGPointMake(5.0, 6.0);
}

@end
