有人成功将 SpeakHere 移植到 ARC 吗?
当我尝试集成 SpeakHere 中的录制/播放代码时,我的编译器报告了很多错误。 我遵循建议使用 .mm 文件来包含 cpp 包含文件,唯一的例外是我使用启用了 ARC 的 iOS 5。
我的代码是:
//header file
#import "AQPlayer.h"
#import "AQRecorder.h"
@interface MyClass : NSObject {
UIButton *record;
UIButton *cancel;
UIButton *stop;
UIButton *play;
//
AQPlayer* player;
AQRecorder* recorder;
BOOL playbackWasInterrupted;
BOOL playbackWasPaused;
CFStringRef recordFilePath;
}
@property (nonatomic, retain) IBOutlet DrawerAudioNote *dnote;
@property (nonatomic, retain) IBOutlet UIButton *record;
@property (nonatomic, retain) IBOutlet UIButton *cancel;
@property (nonatomic, retain) IBOutlet UIButton *stop;
@property (nonatomic, retain) IBOutlet UIButton *play;
- (IBAction) doRecord:(id)sender;
- (IBAction) doStop:(id)sender;
- (IBAction) doCancel:(id)sender;
- (IBAction) doPlay:(id)sender;
//
@property (readonly) AQPlayer *player;
@property (readonly) AQRecorder *recorder;
//.mm file (no compile error)
@import "MyClass.h"
@implementation MyClass
@synthesize record, cancel, stop, play;
@synthesize playbackWasInterrupted;
@synthesize player, recorder;
//CAXException.h (an example cpp file with compile errors)
......
class CAX4CCString {
//ERROR: Expect ';' after top level declarator
//ERROR: Unknown type name; do you mean 'Class'?
public:
CAX4CCString(OSStatus error) {
// see if it appears to be a 4-char-code
char *str = mStr;
*(UInt32 *)(str + 1) = CFSwapInt32HostToBig(error);
if (isprint(str[1]) && isprint(str[2]) && isprint(str[3]) && isprint(str[4])) {
str[0] = str[5] = '\'';
str[6] = '\0';
} else if (error > -200000 && error < 200000)
// no, format it as an integer
sprintf(str, "%d", (int)error);
else
sprintf(str, "0x%x", (int)error);
}
const char *get() const { return mStr; }
operator const char *() const { return mStr; }
private:
char mStr[16];
};
通过“CAX4CCString”类中的编译错误,编译器似乎不明白他正在处理 CPP 文件。 我知道我会在某个地方错过一些东西,有人可以指出吗?
预先感谢,

My compiler reported a lot of error when I were trying to integrate record/play code from SpeakHere.
I have followed suggestions to use a .mm file to include cpp include file, the only exception is I am using iOS 5 with ARC enabled.
My code is:
//header file
#import "AQPlayer.h"
#import "AQRecorder.h"
@interface MyClass : NSObject {
UIButton *record;
UIButton *cancel;
UIButton *stop;
UIButton *play;
//
AQPlayer* player;
AQRecorder* recorder;
BOOL playbackWasInterrupted;
BOOL playbackWasPaused;
CFStringRef recordFilePath;
}
@property (nonatomic, retain) IBOutlet DrawerAudioNote *dnote;
@property (nonatomic, retain) IBOutlet UIButton *record;
@property (nonatomic, retain) IBOutlet UIButton *cancel;
@property (nonatomic, retain) IBOutlet UIButton *stop;
@property (nonatomic, retain) IBOutlet UIButton *play;
- (IBAction) doRecord:(id)sender;
- (IBAction) doStop:(id)sender;
- (IBAction) doCancel:(id)sender;
- (IBAction) doPlay:(id)sender;
//
@property (readonly) AQPlayer *player;
@property (readonly) AQRecorder *recorder;
//.mm file (no compile error)
@import "MyClass.h"
@implementation MyClass
@synthesize record, cancel, stop, play;
@synthesize playbackWasInterrupted;
@synthesize player, recorder;
//CAXException.h (an example cpp file with compile errors)
......
class CAX4CCString {
//ERROR: Expect ';' after top level declarator
//ERROR: Unknown type name; do you mean 'Class'?
public:
CAX4CCString(OSStatus error) {
// see if it appears to be a 4-char-code
char *str = mStr;
*(UInt32 *)(str + 1) = CFSwapInt32HostToBig(error);
if (isprint(str[1]) && isprint(str[2]) && isprint(str[3]) && isprint(str[4])) {
str[0] = str[5] = '\'';
str[6] = '\0';
} else if (error > -200000 && error < 200000)
// no, format it as an integer
sprintf(str, "%d", (int)error);
else
sprintf(str, "0x%x", (int)error);
}
const char *get() const { return mStr; }
operator const char *() const { return mStr; }
private:
char mStr[16];
};
By compilation errors in class 'CAX4CCString', the compiler seems does not understand he is working on CPP file.
I know I would have missed something in somewhere, anyone can point out?
Thanks in advance,
Sean

为什么不对特定文件禁用 ARC?除了有问题的文件外,您的项目仍保留在 ARC 中。将
-fno-objc-arc
添加到您不希望使用 ARC 的文件的编译器标志中。在 Xcode 中,您可以在您的目标 -> 下执行此操作构建阶段 ->编译源。Why not disable ARC for specific files? Your project remains with ARC, except the problematic files. Add
-fno-objc-arc
to the compiler flags for the files you don't want with ARC. In Xcode, you can do this under your target -> Build Phases -> Compile Sources.声明 C++ 类
您正在Objective-C 类
MyClass
中 。我担心 Objective-C 不支持这一点。我认为你可以在全局范围内声明
CAX4CCString
,然后从你的 Objective-C 类中实例化并使用它:You are declaring the C++ class
inside of the Objective-C class
MyClass
. I fear this is not supported by Objective-C.What I think you could so is declare
CAX4CCString
in the global scope and then instantiate and use it from your Objective-C class:
