我有一个viewcontroller,我在其中模拟一个视图。我有一个firstViewController,我有loginViewController。以下是我在firstViewcontroller上弹出loginViewontroller的代码。
在firstViewController.m中
LoginViewController *login = [[LoginViewController alloc]initWithNibName:@"LoginViewController" bundle:NULL];
[self presentModalViewController:login animated:YES];
在loginViewController中我有以下功能。
-(void)initialDelayEnded {
self.view.transform = CGAffineTransformScale(CGAffineTransformIdentity, 0.001, 0.001);
self.view.alpha = 0.0;
[UIView animateWithDuration:1.0/1.5 animations:^{
self.view.transform = CGAffineTransformScale(CGAffineTransformIdentity, 1.1, 1.1);
}completion:^(BOOL complete){
[UIView animateWithDuration:1.0/2 animations:^{
self.view.transform = CGAffineTransformScale(CGAffineTransformIdentity, 0.9, 0.9);
}completion:^(BOOL complete){
[UIView animateWithDuration:1.0/2 animations:^{
self.view.transform = CGAffineTransformIdentity;
}];
}];
}];
}
在firstViewcontroller中我有一个背景图片。我现在要做的是,loginViewcontroller弹出图像仍然可见。
有人能帮助我吗?
提前致谢。
答案 0 :(得分:0)
您无法通过viewcontroller堆栈查看。最简单的解决方案是将firstviewcontroller中的背景图像传递给第二个并将其设置为背景。
在LoginViewController.h上有一个属性
@property (nonatomic, strong) UIImage* image;
然后在实例化控制器时
LoginViewController *login = [[LoginViewController alloc]initWithNibName:@"LoginViewController" bundle:NULL];
login.image = self.backgroundImage; //Set the image to the background image
[self presentModalViewController:login animated:YES];
最后,在loginViewController.m的viewDidLoad
self.view.backgroundColor = [UIColor colorWithPatternImage:self.image];
