如何抑制“类可能无法响应具有变量方法名称的‘-method’警告？

如何使用变量选择器名称来防止此警告？

NSString *methodName;

SEL method = NSSelectorFromString(methodName);

if ([self respondsToSelector:method]) {

    if ([methodName hasSuffix:@":"])
        [self method:dict];
    else
        [self method];

}

Use

[self performSelector:method];

代替

[self method];

And

[self performSelector:method withObject:dict];

代替

[self method:dict];
