ID付きのボールを追加する場所にUIViewがあります。ID 1のボールに触れると、指に沿って破線を描きます。
指を他のボールに移動したときに、これらのボールを検出してIDを確認する方法がわからない場合の問題。私が起こらなければならないことは、ID 2の次のボールに触れると、ラインフィニッシュがボール1からボール2に描画されたままになり、2から指に新しいボールを作成します。
コード:
#import "DrawView.h"
@implementation DrawView
- (id)init
{
self = [super initWithFrame:CGRectMake(0, 0, 1024, 768)];
if (self) {
self.backgroundColor = [UIColor clearColor];
self.opaque = YES;
checkPointCircle = [[CheckPointCircle alloc] initWithPosX:315 posY:138 andNumber:1];
checkPointCircle.userInteractionEnabled = YES;
[self addSubview:checkPointCircle];
checkPointCircle = [[CheckPointCircle alloc] initWithPosX:706 posY:138 andNumber:2];
checkPointCircle.userInteractionEnabled = YES;
[self addSubview:checkPointCircle];
checkPointCircle = [[CheckPointCircle alloc] initWithPosX:315 posY:526 andNumber:3];
checkPointCircle.userInteractionEnabled = YES;
[self addSubview:checkPointCircle];
checkPointCircle = [[CheckPointCircle alloc] initWithPosX:706 posY:526 andNumber:4];
checkPointCircle.userInteractionEnabled = YES;
[self addSubview:checkPointCircle];
}
return self;
}
- (Line *)drawLine {
return drawLine;
}
- (void)setDrawLine:(Line *)line
{
drawLine = line;
}
-(void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event
{
UITouch *touch = [touches anyObject];
CheckPointCircle * checkTouch = (CheckPointCircle *)touch.view;
if (touch.view.class == checkPointCircle.class) {
if ([checkTouch getObjectID] == 1) {
startTouchPoint = CGPointMake([checkTouch center].x, [checkTouch center].y);
endTouchPoint = [touch locationInView:self];
}
}
self.drawLine = [[Line alloc] initWithPoint:[touch locationInView:self]];
[self setNeedsDisplay];
}

NSLog(@"Que toco: %@ ", secondaryTouch.view);
if (touch.view.class == checkPointCircle.class) {
CheckPointCircle * checkTouch = (CheckPointCircle *)touch.view;
if ([checkTouch getObjectID] == 1) {
endTouchPoint = [touch locationInView:self];
}
}

}
[self setNeedsDisplay];
}
- (void)drawRect:(CGRect)rect

IDを取得するために他のボールを検出する方法。
誰か助けてもらえますか?ありがとう!
