经过我的实验，都是只能在动画快结束时能被点击，偏移过程中无法点击。不知道是为什么？
代码如下：（useAutolayout已取消）
#import "ViewController.h"

@interface ViewController ()
@property (weak, nonatomic) IBOutlet UIButton *btnImg;

@end

@implementation ViewController

- (void)viewDidLoad
{
  [super viewDidLoad];
  NSLog(@"btnImg.frame=%@",NSStringFromCGRect(self.btnImg.frame));
  self.btnImg.frame = CGRectMake(100, 0, 200, 200);

  [self.btnImg addTarget:self action:@selector(btNc) forControlEvents:UIControlEventTouchUpInside];
  NSLog(@"btnImg.frame=%@",NSStringFromCGRect(self.btnImg.frame));
  [UIView animateWithDuration:10 delay:1 options:UIViewAnimationOptionAllowUserInteraction animations:^{
    self.btnImg.frame = CGRectMake(100, 400, 200, 200);
        NSLog(@"userInteractionEnabled = %d",self.btnImg.userInteractionEnabled);
        NSLog(@"Enabled = %d",self.btnImg.enabled);
  } completion:nil];
}

oc吗?我还没学到,刚开始学c
