iOS查看类的私有方法

    #import 
    const char *cClassName = [@"UIEvent" UTF8String];
    id classM = objc_getClass(cClassName);
    unsigned int *outCount;
    
    Method *methods = class_copyMethodList(classM, &outCount);
    for (int i = 0; i < outCount; i++) {
        Method method = methods[i];
        NSString *attributeName = NSStringFromSelector(method_getName(method));
        NSLog(@"Method %d: %@", i, attributeName);
    }

输出如下：
