ジグソーアプリケーションを作成しています。各ピースに触れると、正しい場所に配置され、間違った場所にドロップされた場合にブール(droppedInPlace
)が割り当てられるという考え方です。次に、40個のブール(ジグソーピースの数)の配列を作成する必要があると思います。これらの各エントリは、最初はNOに設定されます。YES
NO
次に、このブール値(droppedInPlace
)は、を使用して配列に挿入されreplaceObjectAtIndex
ます。次に、この配列をループします。すべてのエントリがtrue/yes / 1の場合、ジグソーパズルは完了し、いくつかのコードを実行します。
これを行うのに問題があります。上記のアイデアをコーディングする方法がわかりません。以下は私のコードです:
-(void) touchesEnded:(NSSet *)touches withEvent:(UIEvent *)event {
UITouch *touch = [touches anyObject];
UIView *touchedView = [touch view];
// filename to be read from
NSString *filePath = [[NSBundle mainBundle]
pathForResource:
@"jigsawHomeCenterPoints"
ofType:@"plist"];
// array of cgpoints in string format
NSArray *jigsawHomeCentersArray = [NSArray arrayWithContentsOfFile:filePath];
// the tag number of the selected image
int tag = touchedView.tag;
NSLog(@"tag: %i", tag);
// says that the piece has not been dropped in it's holder
bool droppedInPlace = NO;
// if what has been touched is part of the array of images
if ([imagesJigsawPieces indexOfObject:touchedView] != NSNotFound) {
// preparing new snap-to-center position
// using (tag-1) as an index in the HomeCentersArray corresponds to where the image should be placed
// this was a conscious decision to make the process easier
CGPoint newcenter = CGPointFromString([jigsawHomeCentersArray objectAtIndex:tag-1]);
// the location of the current touch
CGPoint location = [touch locationInView:self.view];
// call the animate method upon release
[self animateReleaseTouch:touchedView withLocation:location];
// setting a proximity range - if it is within this 80x80 area the image will snap to it's corresponding holder (HomeCenter)
if (location.x > newcenter.x-40 && location.x < newcenter.x+40
&& location.y > newcenter.y-40 && location.y < newcenter.y+40) {
touchedView.center = newcenter;
touchedView.alpha = 1.0;
droppedInPlace = YES;
} else {
touchedView.alpha = 0.5;
droppedInPlace = NO;
}
NSLog(@"True or false: %i", droppedInPlace);
[self checkJigsawCompleted:droppedInPlace withTag:tag];
}
}
そしてチェック機能:
-(void) checkJigsawCompleted:(BOOL)inPlace withTag:(NSInteger)tag {
NSMutableArray *piecesInPlace;
[piecesInPlace replaceObjectAtIndex:tag-1 withObject:[NSNumber numberWithBool:inPlace]];
//code to loop through array - check if all entries are true/yes/1
//if so, jigsaw is completed - run some other code
//else, do nothing
}
