I have code like this:
我有这样的代码:
NSData *data = [NSData dataWithContentsOfURL:objURL];
const void *buffer = [data bytes];
[self _loadData:buffer];
[data release];
the "_loadData" function takes an argument like:
“_loadData”函数接受如下参数:
- (void)_loadData:(const char *)data;
How do I convert "const void " to a "const char" on Objective-C?
如何将“const void”转换为Objective-C中的“const char”?

Just like you would in C:
就像你在C中写的那样:
[self _loadData:(const char *)buffer];
should work.
应该工作。

You mustn't release the data object because you did not explicitly allocate it. Also, you could do a simple cast:
您不能释放数据对象，因为您没有显式地分配它。同样，你也可以做一个简单的石膏模型:
[self _loadData:(const char *) buffer];
