将"const void*"转换为"const char*"

Question

我有这样的代码:

NSData *data = [NSData dataWithContentsOfURL:objURL];
const void *buffer = [data bytes];
[self _loadData:buffer];
[data release];

"_loadData"函数采用如下参数:

- (void)_loadData:(const char *)data;

如何在Objective-C上将"const void "转换为"const char "？

Answer 1

就像你在C中一样:

[self _loadData:(const char *)buffer];

应该管用.
