ExtAudioFileSetProperty 崩溃的问题

原地址: http://hulefei29.iteye.com/blog/1910362

问题：We are using CocosDenshion for our games. When we turn on exception breakpoints in xcode we keep getting exceptions from

status = ExtAudioFileSetProperty(extRef, kExtAudioFileProperty_ClientDataFormat, sizeof(theOutputFormat), &theOutputFormat);

In CDOpenALSupport.m

(note that this exception does not crash the game as it is caught by CocosDenshion but still we want to see if we can prevent these exceptions).

 

答案：Set the exception breakpoint to handle only Objective-C exceptions. This prevents these Cocosdenshion exceptions from being caught by the breakpoint.

I wager they're nothing to worry about, it's been like that for as long as I can remember.

 

总结：ExtAudioFileSetProperty会抛出异常，但这个异常不会影响程序崩溃，只要忽略这个异常，就可以运行了
