Question

我正在编写显示某些图片的应用程序，当用户点击图片时会调用某些功能

在纵向模式下，我将图像设置为可点击以大规模预览：

[imgv addTarget:self action:@selector(funShowPhoto) forControlEvents:UIControlEventTouchUpInside];

我希望在横向模式下跳过这个功能，我试试这个但是功能还在调用，我该怎么办？

[imgv addTarget:self action:nil forControlEvents:UIControlEventTouchUpInside];

Answer 1

只需在funShowPhoto方法

中添加条件即可

-(void)funShowPhoto
{
// check if device is in portrait orientation
  if([[UIDevice currentDevice]orientation] == UIInterfaceOrientationPortrait | UIInterfaceOrientationPortraitUpsideDown)
  {

   // run your code here device is in Portrait Mode

  }
}

Answer 2

您可以添加以前给出的代码Panayot Panayotov：

imgv.userInteractionEnabled = NO;

这样你就不必改变行动。

Answer 3

- (void)viewDidLoad
{

    UIButton *button_barcord = [UIButton buttonWithType:UIButtonTypeRoundedRect];  // .....button_faves....
    [button_barcord addTarget:self
                       action:@selector(bMethod:)
             forControlEvents:UIControlEventTouchUpInside];
    [button_barcord setBackgroundImage:[UIImage imageNamed:@"yourimag.png"] forState:UIControlStateNormal];

    [button_barcord setTitleColor:[UIColor whiteColor] forState:UIControlStateNormal];

    button_barcord.frame = CGRectMake(240,75,54,54);
    [self.view addSubview:button_barcord];
    [super viewDidLoad];
}
-(IBAction)bMethod:(id)sender
{


}

如何使图像（un-）可点击？
