在iOS-NSException上实例化视图在动画图像数组时捕获

Question

Ken View是IBOutlet JBKenView * kenView的名称 我把它连接到UIView

-(void)viewDidLoad
{

[super viewDidLoad];
// Do any additional setup after loading the view.
self.view.backgroundColor=[UIColor whiteColor];
// NSArray *collage = [NSArray arrayWithObjects:[UIImage imageNamed:@"collage1.jpg"],[UIImage imageNamed:@"collage 2.png"],[UIImage imageNamed:@"collage 3.png"],nil];
self->kenView.layer.borderWidth = 1;
self->kenView.layer.borderColor = [UIColor blackColor].CGColor;


//img.animationImages=collage;
// img.animationDuration=8.0;
//img.animationRepeatCount=0;
//[img startAnimating];
btn.backgroundColor=[UIColor colorWithRed:100.0/255 green:260.0/255 blue:183.0/255 alpha:1.0];
UIDatePicker *datePicker = [[UIDatePicker alloc]init];
[datePicker setDate:[NSDate date]];
[datePicker addTarget:self action:@selector(updateTextField:) forControlEvents:UIControlEventValueChanged];
[text2 setInputView:datePicker];
UITapGestureRecognizer *tap = [[UITapGestureRecognizer alloc]
                               initWithTarget:self
                               action:@selector(dismissKeyboard)];

[self.view addGestureRecognizer:tap];
UIDatePicker *picker = (UIDatePicker*)text2.inputView;

picker.datePickerMode=UIDatePickerModeDate;

}

-(void)viewDidAppear:(BOOL)animated
{
[super viewDidAppear:animated];
NSArray *myImages = @[[UIImage imageNamed:@"collage1.jpg"],
                      [UIImage imageNamed:@"collage2.png"],
                      [UIImage imageNamed:@"collage3.png"],];



[kenView animateWithImages:myImages
        transitionDuration:6
              initialDelay:0
                      loop:YES
               isLandscape:YES];

}

实现此操作会出错：
