我将下面显示的代码更改为ARC兼容。
我刚刚在Xcode建议时更改了它,并且它在Xcode上没有显示错误。但是一旦事件发生,代码就会崩溃。有人有想法解决这个问题吗?
我不确定这种迷恋是否因为acapela SDK而发生。
这是非ARC代码,它运行正常。
void MyInterruptionListener(void *inClientData, UInt32 inInterruptionState) {
AcapelaSpeech* anAcapelaSpeech = *(AcapelaSpeech**)inClientData;
if (inInterruptionState == kAudioSessionBeginInterruption) {
[anAcapelaSpeech setActive:NO];
status = AudioSessionSetActive(NO);
}
if (inInterruptionState == kAudioSessionEndInterruption) {
status = AudioSessionSetActive(YES);
[anAcapelaSpeech setActive:YES];
}
}
这是ARC兼容的,但它会破坏[anAcapelaSpeech setActive:NO] ;.
void MyInterruptionListener(void *inClientData, UInt32 inInterruptionState) {
AcapelaSpeech* anAcapelaSpeech = (__bridge_transfer AcapelaSpeech*)inClientData;
if (inInterruptionState == kAudioSessionBeginInterruption) {
[anAcapelaSpeech setActive:NO];
AudioSessionSetActive(NO);
}
if (inInterruptionState == kAudioSessionEndInterruption) {
AudioSessionSetActive(YES);
[anAcapelaSpeech setActive:YES];
}
}
其他信息。 我正在使用Acapela音频SDK,音频中断代码显示在此PDF的中断。 http://www.ecometrixem.com/cms-assets/documents/44729-919017.acapela-for-iphone.pdf
这是暗恋的截图。
解决 这段代码很有效,谢谢。
void MyInterruptionListener(void *inClientData, UInt32 inInterruptionState) {
AcapelaSpeech *anAcapelaSpeech = (__bridge id) (*(void **) inClientData);
if (inInterruptionState == kAudioSessionBeginInterruption) {
[anAcapelaSpeech setActive:NO];
AudioSessionSetActive(NO);
}
if (inInterruptionState == kAudioSessionEndInterruption) {
AudioSessionSetActive(YES);
[anAcapelaSpeech setActive:YES];
}
}
答案 0 :(得分:6)
你需要这样的东西:
id asObject = (__bridge id) (*(void **) ptr);
