ios - 如何在 iOS 上删除 UIBarButtonItem tintColor 动画？

Question

我这里有一个 BarButtonItem 动画:

[UIView animateWithDuration:AnimDurationTintColorHint delay:0 options:UIViewAnimationOptionRepeat | UIViewAnimationOptionAutoreverse animations:^{
    [view performSelector:@selector(setTintColor:) withObject:UIColor.blackColor];
} completion:^(BOOL finished) {
  ........
}];

因为 UIBarButtonItem 没有层属性，我不能使用 .layer removeAllAnimations 来停止分配的无尽动画。

如何删除它？

Answer 1

您必须使用 leftBarButtonItem 或 rightBarButtonItem，然后将 UIBarButtonItem 的 enabled 属性设置为 NO。

UIImage *img = [UIImage imageNamed:@"your image"];
    UIButton *btnMenu = [UIButton buttonWithType:UIButtonTypeCustom];
    btnMenu.frame = CGRectMake( 10, 0, img.size.width, img.size.height);
    [btnMenu addTarget:self action:@selector(handleBack:) forControlEvents:UIControlEventTouchUpInside];
    [btnMenu setImage:img forState:UIControlStateNormal];
    UIBarButtonItem *backButton = [[UIBarButtonItem alloc] initWithCustomView:btnMenu];
    self.navigationItem.leftBarButtonItem = backButton;
self.navigationItem.leftBarButtonItem.enabled = NO;
