Question

我正在尝试创建一个噪音应用程序，但卡住了。我不是开发人员而只是为了好玩而创建它！

问题在于我收到一条错误，上面写着＆＃34;预期的标识符或＆＃39;（＆＃39;＆＃34;在＆＃34; @interface ViewController：NSObject：UIViewController＆＃34; line在ViewController.h中。

ViewController.h的代码是：

@interface ViewController : NSObject  :UIViewController {
}

-(IBAction)sound1;
-(IBAction)sound2;
-(IBAction)sound3;
-(IBAction)sound4;
-(IBAction)sound5;
-(IBAction)sound6;

@end

ViewController.m的代码是：

#import "ViewController.h"

@implementation ViewController : NSObject;

-(IBAction)five {
    CFBundleRef mainBundle = CFBundleGetMainBundle();
    CFURLRef soundFileURLRef;
    soundFileURLRef = CFBundleCopyResourceURL(mainBundle, (CFStringRef) @"sound1", CFSTR("wav"), NULL);
    UInt32 soundID;
    AudioServicesCreateSystemSoundID(soundFileURLRef, &soundID);
    AudioServicesPlaySystemSound(soundID);
}

-(IBAction)cramp {
    CFBundleRef mainBundle = CFBundleGetMainBundle();
    CFURLRef soundFileURLRef;
    soundFileURLRef = CFBundleCopyResourceURL(mainBundle, (CFStringRef) @"sound2", CFSTR("wav"), NULL);
    UInt32 soundID;
    AudioServicesCreateSystemSoundID(soundFileURLRef, &soundID);
    AudioServicesPlaySystemSound(soundID);
}

-(IBAction)cycling {
    CFBundleRef mainBundle = CFBundleGetMainBundle();
    CFURLRef soundFileURLRef;
    soundFileURLRef = CFBundleCopyResourceURL(mainBundle, (CFStringRef) @"sound3", CFSTR("wav"), NULL);
    UInt32 soundID;
    AudioServicesCreateSystemSoundID(soundFileURLRef, &soundID);
    AudioServicesPlaySystemSound(soundID);
}

-(IBAction)iLoveBanking {
    CFBundleRef mainBundle = CFBundleGetMainBundle();
    CFURLRef soundFileURLRef;
    soundFileURLRef = CFBundleCopyResourceURL(mainBundle, (CFStringRef) @"sound4", CFSTR("wav"), NULL);
    UInt32 soundID;
    AudioServicesCreateSystemSoundID(soundFileURLRef, &soundID);
    AudioServicesPlaySystemSound(soundID);
}

-(IBAction)sound5 {
    CFBundleRef mainBundle = CFBundleGetMainBundle();
    CFURLRef soundFileURLRef;
    soundFileURLRef = CFBundleCopyResourceURL(mainBundle, (CFStringRef) @"sound5", CFSTR("wav"), NULL);
    UInt32 soundID;
    AudioServicesCreateSystemSoundID(soundFileURLRef, &soundID);
    AudioServicesPlaySystemSound(soundID);
}

-(IBAction)sound6 {
    CFBundleRef mainBundle = CFBundleGetMainBundle();
    CFURLRef soundFileURLRef;
    soundFileURLRef = CFBundleCopyResourceURL(mainBundle, (CFStringRef) @"sound6", CFSTR("wav"), NULL);
    UInt32 soundID;
    AudioServicesCreateSystemSoundID(soundFileURLRef, &soundID);
    AudioServicesPlaySystemSound(soundID);
}

@end

HELP !!!!!!

Answer 1

这段代码迫不及待重构......

帮助查找导致问题的原因。
让它更容易使用。

你去......

#import "ViewController.h"

@implementation ViewController

-(IBAction)five {
    [self playSoundWithName:@"sound1"];
}

-(IBAction)cramp {
    [self playSoundWithName:@"sound2"];
}

-(IBAction)cycling {
    [self playSoundWithName:@"sound3"];
}

-(IBAction)iLoveBanking {
    [self playSoundWithName:@"sound4"];
}

-(IBAction)sound5 {
    [self playSoundWithName:@"sound5"];
}

-(IBAction)sound6 {
    [self playSoundWithName:@"sound6"];
}

- (void)playSoundWithName:(NSString *)name
{
    CFBundleRef mainBundle = CFBundleGetMainBundle();
    CFURLRef soundFileURLRef;
    soundFileURLRef = CFBundleCopyResourceURL(mainBundle, (CFStringRef)name, CFSTR("wav"), NULL);
    UInt32 soundID;
    AudioServicesCreateSystemSoundID(soundFileURLRef, &soundID);
    AudioServicesPlaySystemSound(soundID);
}

@end

此外，您的标题应该是......

@interface ViewController : UIViewController

@end

如果您只是从按钮调用IBAction方法，则根本不需要在标题中声明它们。

Answer 2

@interface ViewController：NSObject：UIViewController

这是错误的，你不能有多个班级。你只能从一个子类。由于你在.m文件中有一些IBAction，我想你是用它作为视图控制器而在.h文件中删除NSObject。 @interface ViewController : UIViewController

在.m中它应该是

@implementation ViewController

Answer 3

你不能继承两个班级;只需使用UIViewController：

@interface ViewController : UIViewController

Answer 4

像这样编写.h文件

   @interface ViewController :UIViewController

  -(IBAction)sound1;
-(IBAction)sound2;
 -(IBAction)sound3;
-(IBAction)sound4;
-(IBAction)sound5;
  -(IBAction)sound6;
  @end

和.m文件用UIViewController替换NSObject

    #import "ViewController.h"
      @implementation ViewController : UIViewController;

解析问题预期标识符或＆＃34;（＆＃34;
