本文详细介绍了如何使用Objective-C编程语言实现视图隐藏与显示，并通过代码实例展示了如何加载并显示指定图片，适用于iOS应用开发场景。
- (void)loadView {
[[UIApplication sharedApplication] setStatusBarHidden:YES withAnimation: UIStatusBarAnimationSlide];
UIImage *image=[UIImage imageNamed:@"1.jpg"];
CGRect rect = CGRectMake(60, 80, 331, 353);//创建矩形框
UIImageView *contentView = [[UIImageView alloc] initWithFrame:rect];
contentView.image=[UIImage imageWithCGImage:CGImageCreateWithImageInRect([image CGImage], rect)];
self.view=[[UIView alloc] initWithFrame:[[UIScreen mainScreen] applicationFrame]];
[self.view addSubview:contentView];
[image release];
}
[[UIApplication sharedApplication] setStatusBarHidden:YES withAnimation: UIStatusBarAnimationSlide];
UIImage *image=[UIImage imageNamed:@"1.jpg"];
CGRect rect = CGRectMake(60, 80, 331, 353);//创建矩形框
UIImageView *contentView = [[UIImageView alloc] initWithFrame:rect];
contentView.image=[UIImage imageWithCGImage:CGImageCreateWithImageInRect([image CGImage], rect)];
self.view=[[UIView alloc] initWithFrame:[[UIScreen mainScreen] applicationFrame]];
[self.view addSubview:contentView];

}
