同様の質問がたくさんあることは知っていますが、どの回答も私の問題を解決するのに役立ちませんでした。
1つのウィンドウを移動すると機能があります：
-(void)flowLayout:(SEssentialsFlowLayout *)flow didDragView:(UIView *)view{
NSLog(@"drag");
BOOL needDeleteFavourites = NO;
CGPoint dragScrollPosition = [flow convertPoint:view.center toView:self];
CGPoint dragPosition = [flow convertPoint:view.center toView:self.scroll];
// original grupe view
UIGroupView * orgGrView = (UIGroupView *)flow.superview.superview;
UIScrollView * orgScroll = (UIScrollView *)flow.superview;
for (SEssentialsFlowLayout * destinationFlow in self.flows) {
// destination grupe view
UIGroupView * grView = (UIGroupView *)destinationFlow.superview.superview;
UIScrollView * scroll = (UIScrollView *)destinationFlow.superview;
if (flow != destinationFlow && grView.grupes.type == GrupeTypeEditable) {
if (CGRectContainsPoint(destinationFlow.superview.superview.frame, dragPosition)) {
view.center = [scroll convertPoint:dragPosition toView:scroll];
// calculate cube space
int numberOfCubeOnScreen = grView.frame.size.width / (grView.frame.size.height * grView.cubeWidth) ;
int delta = grView.frame.size.width - (grView.frame.size.height * grView.cubeWidth * numberOfCubeOnScreen);
float oneDelta = (float) delta/(numberOfCubeOnScreen );
// destination grupe view
int numberOfpage = ceil((grView.frame.size.height * grView.cubeWidth + oneDelta)* (destinationFlow.managedViews.count + 2) / grView.frame.size.width);
destinationFlow.frame = CGRectMake(0, 0, grView.frame.size.width * numberOfpage, grView.frame.size.height * 0.68);
scroll.contentSize = CGSizeMake(destinationFlow.frame.size.width, destinationFlow.frame.size.height);
[grView.pageControll setNumberOfPages:numberOfpage];
if (orgGrView.grupes.type == GrupeTypeNotEditable) {
// grabcube view
UICubeVeiw * oldCubeView = (UICubeVeiw *)view;
// create new cube and new cube view
Cube * newCube = [oldCubeView.cube copyCube];
UICubeVeiw * newCubeVew = [oldCubeView copyCubeView:oldCubeView.cube];
// copy new cube into old cube view
oldCubeView.cube = newCube;
// add new cube view on old flow
int newIndex = [flow.managedViews indexOfObject:view];
if (newIndex > 0 && newIndex< flow.managedViews.count) {
[flow unmanageSubview:view];
[flow addManagedSubview:newCubeVew atIndex:newIndex];
// move old cube view on new flow
[destinationFlow addManagedSubview:view];
}
}
else{
// original grupe view
int orgNumberOfpage = ceil((orgGrView.frame.size.height * grView.cubeWidth +oneDelta ) * (flow.managedViews.count ) / orgGrView.frame.size.width);
flow.frame = CGRectMake(0, 0, orgGrView.frame.size.width * orgNumberOfpage, orgGrView.frame.size.height * 0.68);
orgScroll.contentSize = CGSizeMake(flow.frame.size.width, flow.frame.size.height);
[orgGrView.pageControll setNumberOfPages:orgNumberOfpage];
[flow unmanageSubview:view];
[destinationFlow addManagedSubview:view];
[orgGrView.grupes removeCube:((UICubeVeiw *)view).cube];
}
needDeleteFavourites = YES;
}
}
}
NSLog(@"pozicija originala : %f ", orgGrView.grupes.positionIndex);
if (orgGrView.grupes.positionIndex == 1 && needDeleteFavourites && orgGrView.grupes.cubes.count<1) {
NSLog(@"remove");
[self removeFavouritesFromView];
}
// move scroll view up and down
if (dragScrollPosition.y < self.frame.size.height * 0.16) {
NSLog(@"move down");
if (!self.timerIsSet) {
NSLog(@"move down 1");
self.timerIsSet = YES;
NSLog(@"move down 2");
self.timer = [NSTimer scheduledTimerWithTimeInterval:0.5f target:self selector:@selector(moveScrollVeiwUp) userInfo:nil repeats:NO ];
}
}
else if (dragScrollPosition.y > self.frame.size.height * 0.88) {
if (!self.timerIsSet) {
NSLog(@"move up");
self.timerIsSet = YES;
self.timer = [NSTimer scheduledTimerWithTimeInterval:0.5f target:self selector:@selector(moveScrollVeiwDown) userInfo:nil repeats:NO ];
}
}
else{
NSLog(@"move none");
self.timerIsSet = NO;
[self.timer invalidate];
self.timer = nil;
self.isFavouriteCurrentlyVisible = NO;
}
}
大量のコードであることはわかっていますが、このウィンドウを移動すると奇妙なエラーが発生します。

これは、私が正しく理解している場合、どこかで無効なインデックスを取得し、それを使用して配列を調べる必要があることを意味します。
しかし、インデックスが許容値の範囲内にあるかどうかを常に確認します。
編集 ：
アドバイスされたように、例外ブレークポイントを設定しましたが、残念ながらブレークポイントは次の場所で停止します:
int main(int argc, char *argv[])
{
@autoreleasepool {
return UIApplicationMain(argc, argv, nil, NSStringFromClass([AppDelegate class]));
}
}
役立つ場合は、スタック トレースを出力しました。
