iOS Performselector withObject 传

- (BOOL)connectionRoom:(BOOL)isReconncet：{
}

之前这些写，以为调用connectionRoom的参数isReconncet是NO，在debug模式下确实是NO，但是在release模式下参数isReconncet是YES，害的问题查了好久，坑啊

原因：

withObject参数传nil才是NO

传任何其他参数代表YES

以下是stackoverflow给出的相关解释：

The simplest way is as follows:

If you have method

-(void)doSomething:(BOOL)flag

and want to performSelecor with flag=NO use

[object performSelector:@selector(doSomething:) withObject:nil];

In case of flag=YES you can send any object, for example, @YES - number from bool

[object performSelector:@selector(doSomething:) withObject:@YES];

Note: don't use @NO ! Only nil will be interpreted as NO in your method with bool argument.
