1. 字符串转时间 ： 时区问题

    formatter.timeZone = [NSTimeZone timeZoneForSecondsFromGMT:0];

    NSLog(@"%@",[NSTimeZone systemTimeZone]);
    NSLog(@"%@",[NSTimeZone localTimeZone]);

2.

    // 通知中心监听屏幕方向
    [[NSNotificationCenter defaultCenter]addObserver:self selector:@selector(changeRotate:) name:UIApplicationDidChangeStatusBarFrameNotification object:nil];

#pragma mark - 监听屏幕方向
- (void)changeRotate:(NSNotification*)noti {
    if ([[UIDevice currentDevice] orientation] == UIInterfaceOrientationPortrait
        || [[UIDevice currentDevice] orientation] == UIInterfaceOrientationPortraitUpsideDown) {
        //竖屏
        NSLog(@"竖屏");
        CGFloat scale = 368.0/GUIScreenWidth;
        self.player.playerView.frame = CGRectMake(0, 20, GUIScreenWidth, 640/scale);
        self.ppBtn = [[UIButton alloc] initWithFrame:CGRectMake(0, CGRectGetMaxY(self.player.playerView.frame), 49, 49)];
        
    } else {
        //横屏
        NSLog(@"横屏");
        self.player.playerView.frame = CGRectMake(0, 0, GUIScreenWidth, GUIScreenHeight);
    }
