iphone - 弹出方向更改

Question

在此应用程序中，从纵向模式开始。

.

代码片段

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轮换。任何参考链接或建议，真的很感激。

Answer 1

返回 NO 从

 - (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。

Answer 2

请在 viewdidlod 注册轮换通知

• (void)viewDidLoad

{

UIInterfaceOrientation currentOrientation = [[UIApplication sharedApplication]   statusBarOrientation];

if (currentOrientation == UIInterfaceOrientationLandscapeLeft || currentOrientation == UIInterfaceOrientationLandscapeRight)
    [self willRotateToLandscape];
else
    [self willRotateToPortrait];


[[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(willRotateToLandscape) name:@"Interface will rotate to landscape" object:nil];


[[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(willRotateToPortrait) name:@"Interface will rotate to portrait" object:nil];

}

//然后在以下函数中调整弹出视图大小。- (void)willRotateToLandscape { } - (void)willRotateToPortrait { }
