弹出方向改变

Question

在此应用程序中启动纵向模式.

.

代码段

NSInteger heightOne;
    NSInteger heightTwo;
    NSInteger imgV;
    CGRect Bounds = [[UIScreen mainScreen] bounds];
if (Bounds.size.height == 568) {
    // code for 4-inch screen
    heightOne = 480+38;
    heightTwo = 240+38;//370
    imgV = 360;

} else {
    // code for 3.5-inch screen
    heightOne = 480;
    heightTwo = 240;//330
    imgV = 310;

}

UIView *firstView = [[UIView alloc] initWithFrame:CGRectMake(00, 00,320,heightOne)];
firstView.opaque = NO;
firstView.tag = 1000;
firstView.backgroundColor = [[UIColor blackColor] colorWithAlphaComponent:0.5f];
[self.view addSubview:firstView];



UIImageView *img = [[UIImageView alloc]initWithFrame:CGRectMake(250,imgV,50,50)];
img.image = [UIImage imageNamed:@"Zoom.jpg"];
[firstView addSubview:img];

UIView *secondView= [[UIView alloc] initWithFrame:CGRectMake(0,0,320,heightOne)];
[secondView setBackgroundColor:[UIColor clearColor]];
[firstView addSubview:secondView];

UIView *thirdView = [[UIView alloc] initWithFrame:CGRectMake(15,60,290,heightTwo)];//30
[thirdView setBackgroundColor:[UIColor whiteColor]];
thirdView.layer.cornerRadius = 2.0f;
thirdView.layer.borderWidth = 4.0f;
thirdView.layer.borderColor = [UIColor colorWithRed:0.0/255.0 green:100.0/255.0 blue:0.0/255.0 alpha:1.0].CGColor;
[secondView insertSubview:thirdView atIndex:0];    


///////////////////////////// Creating custom close button ////////////////////////////////


UIButton *button = [UIButton buttonWithType:UIButtonTypeCustom];
[button setFrame:CGRectMake(287,48,30,30)];//24
[button setBackgroundImage:[UIImage imageNamed:@"Close-Gr.png"] forState:UIControlStateNormal];
[button addTarget:self action:@selector(dismissOverViewController) forControlEvents:UIControlEventTouchUpInside];
button.backgroundColor = [UIColor clearColor];
[secondView insertSubview:button aboveSubview:thirdView];
secondView.frame = CGRectMake(0,0,320,480);
[UIView animateWithDuration:0.3
                 animations:^{
                     secondView.frame = CGRectMake(0,0,320,480);
                 }];


[thirdView setBackgroundColor:[UIColor grayColor]];        

}

在这里我只需要弹出旋转.任何参考链接或建议,真的很感激.

Answer 1

从中返回NO

 - (void)willRotateToInterfaceOrientation:(UIInterfaceOrientation)toInterfaceOrientation duration:(NSTimeInterval)duration

通过本地通知处理设备旋转: -

  [[NSNotificationCenter defaultCenter] addObserver:self 
                                         selector:@selector(didRotate:)
                                             name:UIDeviceOrientationDidChangeNotification
                                           object:nil];

并根据需要旋转视图: -

 self.theView.transform = CGAffineTransformIdentity;
 self.theView.transform = CGAffineTransformMakeRotation(degreesToRadians(-90));

愿这对你有所帮助.
