预期的方法体误差？

Question

当我尝试在Xcode上运行我的应用程序时，我继续收到“预期方法正文”错误。粗体的地方是我收到错误的地方。救命！！！还有一件事，我继续在“@implementation SoundnoardFirstViewController”部分收到错误说“不完整的实现”。救命！！感谢

#import "SoundnoardFirstViewController.h"

@interface SoundnoardFirstViewController ()

@end

@implementation SoundnoardFirstViewController

-(IBAction)PlaySound1:(id)sender1

**-(IBAction)PlaySound2:(id)sender2**

-(IBAction)PlaySound3:(id)sender3

-(IBAction)PlaySound4:(id)sender4

-(IBAction)PlaySound5:(id)sender5

-(IBAction)PlaySound6:(id)sender6

(IBAction)PlaySound1:(id)sender1:(id)sender { 
    CFBundleRef mainBundle = CFBundleGetMainBundle();
    CFURLRef soundFileURLRef;
    soundFileURLRef = CFBundleCopyResourceURL(mainBundle, (CFStringRef) @"This is the name of the clip", CFSTR ("sound file type"), NULL);
    UInt32 soundID;
    AudioServicesCreateSystemSoundID(soundFileURLRef, &soundID);
    AudioServicesPlaySystemSound(soundID);
 }

-(IBAction)PlaySound2:(id)sender2:(id)sender{ 
    CFBundleRef mainBundle = CFBundleGetMainBundle();
    CFURLRef soundFileURLRef;
    soundFileURLRef = CFBundleCopyResourceURL(mainBundle, (CFStringRef) @"DoYouHave?", CFSTR ("mp3"), NULL);
    UInt32 soundID;
    AudioServicesCreateSystemSoundID(soundFileURLRef, &soundID);
    AudioServicesPlaySystemSound(soundID);
}

-(IBAction)PlaySound3:(id)sender3:(id)sender {
    CFBundleRef mainBundle = CFBundleGetMainBundle();
    CFURLRef soundFileURLRef;
    soundFileURLRef = CFBundleCopyResourceURL(mainBundle, (CFStringRef) @"Hello", CFSTR ("mp3"), NULL);
    UInt32 soundID;
    AudioServicesCreateSystemSoundID(soundFileURLRef, &soundID);
    AudioServicesPlaySystemSound(soundID);
}

-(IBAction)PlaySound4:(id)sender4:(id)sender {
    CFBundleRef mainBundle = CFBundleGetMainBundle();
    CFURLRef soundFileURLRef;
    soundFileURLRef = CFBundleCopyResourceURL(mainBundle, (CFStringRef) @"SoupBetter?", CFSTR ("mp3"), NULL);
    UInt32 soundID;
    AudioServicesCreateSystemSoundID(soundFileURLRef, &soundID);
    AudioServicesPlaySystemSound(soundID);
}

在SoundnoardFirstViewController ()

中声明私有方法

@interface SoundnoardFirstViewController ()

  //declare the private methods here

@end

示例：

#import "SoundnoardFirstViewController.h"

@interface SoundnoardFirstViewController ()

-(IBAction)PlaySound1:(id)sender1:(id)sender;
-(IBAction)PlaySound2:(id)sender2:(id)sender

@end

@implementation SoundnoardFirstViewController

-(IBAction)PlaySound1:(id)sender1:(id)sender { 
    CFBundleRef mainBundle = CFBundleGetMainBundle();
    CFURLRef soundFileURLRef;
    soundFileURLRef = CFBundleCopyResourceURL(mainBundle, (CFStringRef) @"This is the name of the clip", CFSTR ("sound file type"), NULL);
    UInt32 soundID;
    AudioServicesCreateSystemSoundID(soundFileURLRef, &soundID);
    AudioServicesPlaySystemSound(soundID);
 }

-(IBAction)PlaySound2:(id)sender2:(id)sender{ 
    CFBundleRef mainBundle = CFBundleGetMainBundle();
    CFURLRef soundFileURLRef;
    soundFileURLRef = CFBundleCopyResourceURL(mainBundle, (CFStringRef) @"DoYouHave?", CFSTR ("mp3"), NULL);
    UInt32 soundID;
    AudioServicesCreateSystemSoundID(soundFileURLRef, &soundID);
    AudioServicesPlaySystemSound(soundID);
}
@end

您在执行发件人之前错过了-：

(IBAction)PlaySound1:(id)sender1:(id)sender {
