因此,我的照片应用程序中的过滤器按钮出现问题。我不确定为什么,但他们突然停止工作。当选择器被轻敲时不会被调用,但我不知道为什么。他们几天前工作得很好,但由于某种原因,他们现在不是。我已经检查过UIView子视图数组,验证它是正确的。我需要一种方法来查看是否由于某种原因,触摸没有进入按钮。我不知道如何做到这一点。UIButton突然停止工作
我希望我有更多的信息给予,但这是我所拥有的。我希望有人提出一些建议,因为我的智慧已经结束了。
在此先感谢!
按钮创建方法:
-(void)createFilterButtonsForThumbnail:(UIImage *)thumbnail
{
UIView *filtersContainer = self.filterContainer;
CGRect buttonFrame = CGRectMake(kFilterFrameThickness, kFilterFrameThickness,
thumbnail.size.width, thumbnail.size.height);
CGFloat frameWidth = thumbnail.size.width+(2*kFilterFrameThickness);
CGFloat frameHeight = kFilterPickerHeight;
UIEdgeInsets backgroundInsets = UIEdgeInsetsMake(0, kFilterFrameThickness, 0, kFilterFrameThickness);
UIImage *buttonBackgroundImage = [[UIImage imageNamed:@"FilmReel"] resizableImageWithCapInsets:backgroundInsets];
for (int i = 0;i<(self.filterPaths.count+kFilterNonLookups+1);i++){
UIImageView *buttonBackground = [[UIImageView alloc] initWithFrame:CGRectMake(kFilterSidePadding+(i*(frameWidth+kFilterSidePadding)),
0,
frameWidth,
frameHeight)];
[buttonBackground setImage:buttonBackgroundImage];
UIButton *thumbnailButton = [[UIButton alloc] initWithFrame:buttonFrame];
UIImage *filteredThumbnail = [self applyFilterAtIndex:i ToImage:thumbnail];
[thumbnailButton setImage:filteredThumbnail forState:UIControlStateNormal];
[thumbnailButton addTarget:self action:@selector(filterSelected:) forControlEvents:UIControlEventTouchUpInside];
[thumbnailButton setTag:i];
[buttonBackground addSubview:thumbnailButton];
[filtersContainer addSubview:buttonBackground];
if ((i > (kFilterProMinimumIndex)) && ([self isProVersion]) == NO){
UIImageView *proTag = [[UIImageView alloc] initWithImage:nil];
CGRect proFrame = CGRectMake(buttonFrame.origin.x,
buttonFrame.origin.y + buttonFrame.size.height - kFilterProIconHeight-kFilterFrameThickness,
kFilterProIconWidth,
kFilterProIconHeight);
[proTag setBackgroundColor:[UIColor orangeColor]];
[proTag setFrame:proFrame];
[thumbnailButton addSubview:proTag];
[self.filterProTags addObject:proTag];
}
}
}
选择方法:
-(void)filterSelected:(UIButton *)button
{
NSLog(@"Pressed button for index %i",button.tag);
int buttonTag = button.tag;
if ((buttonTag < kFilterProMinimumIndex+1) || ([self isProVersion] == YES)){
[self.imageView setImage:[self applyFilterAtIndex:buttonTag ToImage:self.workingImage]];
}
else {
[self processProPurchaseAfterAlert];
}
}
我实际上已经尝试了顶部,它没有修复它,所以我抹去了它。为了约定,我把它放回去了。但是,在背景和按钮上的userInteractionEnabled都设置为YES,这明确地解决了这个问题。非常感谢你,我无法弄清楚这一点! – Rob
