ios界面切换效果实例代码

先看效果：

下面贴代码：

#import "ViewController.h" 
 
@interface ViewController () 
 
@property (weak, nonatomic) IBOutlet UIImageView *backgroundView; 
@property (strong,nonatomic) NSArray *array; 
 
@end 
 
@implementation ViewController 
 
-(NSArray *)array { 
  if (_array == nil) { 
    UIImage *image1 = [UIImage imageNamed:@"01.jpg"]; 
    UIImage *image2 = [UIImage imageNamed:@"02.jpg"]; 
    _array = @[image1,image2]; 
  } 
  return _array; 
} 
 
- (void)viewDidLoad { 
  [super viewDidLoad]; 
  self.backgroundView.image = self.array[0]; 
  // Do any additional setup after loading the view, typically from a nib. 
} 
 
-(void)changeImage { 
  if (self.backgroundView.image == self.array[0]) { 
    self.backgroundView.image = self.array[1]; 
  }else { 
    self.backgroundView.image = self.array[0]; 
  } 
} 
 
- (IBAction)pushClick:(id)sender { 
  [self changeImage]; 
  CATransition *transtion = [[CATransition alloc] init]; 
  transtion.type = @"push"; 
  transtion.subtype = kCATransitionFromBottom; 
  transtion.startProgress = 0.5; 
  transtion.endProgress = 0.8; 
  [self.view.layer addAnimation:transtion forKey:nil]; 
} 
 
/* 
 效果有好多种，上面代码只贴出了其中一种，如果需要其他效果，只需要将 
 transtion.type = @"push";中的type改一下就行。 
 比如： 
 transtion.type = @"fade"; 
 type的类型还有以下几种： 
 fade，reveal，moveIn，cube，suckEffect，oglFlip，rippleEffect，pageCurl，pageCurl，camerAIrisHollowOpen，cameraIrisHollowClose，pageUnCurl，pageCurl，pageCurl，pageCurl
