iOS关于通知传值Bool类型的注意点

    [[NSNotificationCenter defaultCenter] postNotificationName:@"Notification_Name" object:nil userInfo:@{@"paramName":@YES}];

-(void)Handle:(NSNotification *)notification{
    BOOL isFirst = notification.userInfo[@"isFirstLocation"];
    NSLog(@"isFirst:%d",isFirst);
    //这里不能直接写 if (isFirst),必须如下写法
    if (isFirst == 1) {
        //表示Yes
    }
}
