this is the view controller.h

#import <UIKit/UIKit.h>
#import <AudioToolbox/AudioToolbox.h>

@interface ViewController : UIViewController
- (IBAction)yooo:(id)sender;

- (IBAction)boom:(id)sender;


@end

this is the view controller.m

- (IBAction)yooo:(id)sender {

    CFBundleRef mainbundle = CFBundleGetMainBundle();
    CFURLRef soundFileUrlRef;
    soundFileUrlRef = CFBundleCopyResourceURL(mainbundle, (CFStringRef) @"tb1", CFSTR ("wav"), NULL); 
    UInt32 soundID;
    AudioServicesCreateSystemSoundID(soundFileUrlRef, &soundID);
    AudioServicesPlaySystemSound(soundID);}

- (IBAction)boom:(id)sender {


    CFBundleRef mainbundle = CFBundleGetMainBundle();
    CFURLRef soundFileUrlRef;
    soundFileUrlRef = CFBundleCopyResourceURL(mainbundle, (CFStringRef) @"ta1", CFSTR ("wav"), NULL); 
    UInt32 soundID;
    AudioServicesCreateSystemSoundID(soundFileUrlRef, &soundID);
    AudioServicesPlaySystemSound(soundID);
}

Answer 1

您需要做的是找到构建阶段，然后单击+并添加audio.framework ，然后尝试run and build ，一切都应该很好。

Answer 2

You need to set an exception breakpoint. See "Run > Stop on Objective-C exception" in Xcode 4? . If you don't have an exception breakpoint and an exception occurs, all you will see is just a SIGABRT with no stack, so you can't find out, what really happened.
