我的 ImageView 动画有问题。在我看来，有超过 10 个 View ，每个 View 都通过其标签值进行标识，并且我有 UIImageView 和 UIButton。当点击按钮时， View 的特定图像必须被动画化。如果有任何其他图像处于动画状态，则必须停止它。这是我的代码:
-(void)makeAnimation:(UIButton *)sender {
UIView *tagView=(UIView *)[self.view viewWithTag:sender.tag];
UIView *next=nil;
UIView *previous=nil;
NSLog(@"%d",sender.tag);
for (UIImageView * imageview in [tagView subviews]) {
if ([imageview isKindOfClass:[UIImageView class]]) {
if ([imageview isAnimating]) {
NSLog(@"Animation Happens");
}
else{
imageview.animationDuration=2.0;
imageview.animationImages=[animationArray objectAtIndex:sender.tag-1];
imageview.animationRepeatCount=2;
imageview.tag=sender.tag;
[imageview startAnimating];
}
}
}
next=(UIView*)[self.view viewWithTag:sender.tag+1];
previous=(UIView*)[self.view viewWithTag:sender.tag-1];
NSLog(@"NOT IDEA");
[self previousview:previous nextview:next];
}
-(void)previousview:(UIView *)previous nextview:(UIView*)next
{
for (UIImageView * imageview in [previous subviews]) {
if ([imageview isKindOfClass:[UIImageView class]]) {
[imageview stopAnimating];
NSLog(@"PRREVIOUS");
}
}
for (UIImageView * imageview in [next subviews]) {
if ([imageview isKindOfClass:[UIImageView class]]) {
[imageview stopAnimating];
NSLog(@"NEXT");
}
}
}
现在我的问题是，当我依次选择 4 个以上按钮时，我的应用程序崩溃并出现内存警告。
最佳答案
运行时使用配置文件查找泄漏的确切位置，并使用@autorelease{}手动处理内存 像这样..
-(void)makeAnimation:(UIButton *)sender {
@autorelease{
UIView *tagView=(UIView *)[self.view viewWithTag:sender.tag];
UIView *next=nil;
UIView *previous=nil;
NSLog(@"%d",sender.tag);
for (UIImageView * imageview in [tagView subviews]) {
if ([imageview isKindOfClass:[UIImageView class]]) {
if ([imageview isAnimating]) {
NSLog(@"Animation Happens");
}
else{
imageview.animationDuration=2.0;
imageview.animationImages=[animationArray objectAtIndex:sender.tag-1];
imageview.animationRepeatCount=2;
imageview.tag=sender.tag;
[imageview startAnimating];
}
}
}
next=(UIView*)[self.view viewWithTag:sender.tag+1];
previous=(UIView*)[self.view viewWithTag:sender.tag-1];
NSLog(@"NOT IDEA");
[self previousview:previous nextview:next];
}
}
