是否有人设法在arc下使用objc_getClassList,而不是为相关文件关闭弧线?
基本问题是其中一个参数是C类指针类。
答案 0 :(得分:34)
此代码应在ARC下运行:
int numClasses;
Class *classes = NULL;
classes = NULL;
numClasses = objc_getClassList(NULL, 0);
NSLog(@"Number of classes: %d", numClasses);
if (numClasses > 0 )
{
classes = (__unsafe_unretained Class *)malloc(sizeof(Class) * numClasses);
numClasses = objc_getClassList(classes, numClasses);
for (int i = 0; i < numClasses; i++) {
NSLog(@"Class name: %s", class_getName(classes[i]));
}
free(classes);
}
