嗨,我是iPhone開發新手。
我以編程方式在按鈕單擊上創建UIImageViews。但每次我點擊按鈕,他們都會在同一個地方畫出來。圖像繪製代碼如下。檢查顯示在UIScrollview的圖像
- (IBAction)Button
{
arrayOfImages = [[NSMutableArray alloc]init];
float x = 15.0,y = 15.0, width = 100.0, height = 100;
CGRect frame = CGRectMake(x, y, width, height);
int i= 0;
if ([shape isEqualToString:@"Rectangle"])
{
UIGraphicsBeginImageContext(frame.size);
CGContextRef context = UIGraphicsGetCurrentContext();
CGContextSetLineWidth(context, 2.0);
CGRect main =CGRectMake(x, y, 70.0, 30.0);
CGContextFillRect(context, main);
CGRect topSeat1 = CGRectMake(15.0, 0.0, 15.0, 13.0);
CGRect topSeat2 = CGRectMake(42.5, 0.0, 15.0, 13.0);
CGRect topSeat3 = CGRectMake(70.0, 0.0, 15.0, 13.0);
CGRect leftSeat = CGRectMake(0.0, 22.5, 13.0, 15.0);
CGRect rightSeat = CGRectMake(87.0, 22.5, 13.0, 15.0);
[[UIColor redColor]set];
//UIRectFill(main);
UIRectFill(topSeat1);
UIRectFill(topSeat2);
UIRectFill(topSeat3);
UIRectFill(leftSeat);
UIRectFill(rightSeat);
UIRectFrame(main);
[[UIColor blackColor]set];
UIRectFrame(topSeat1);
UIRectFrame(topSeat2);
UIRectFrame(topSeat3);
UIRectFrame(leftSeat);
UIRectFrame(rightSeat);
UIImage * images = [[UIImage alloc]init];
images = UIGraphicsGetImageFromCurrentImageContext();
UIImageView* myImage=[[UIImageView alloc]initWithFrame:frame];
[myImage setImage:images];
myImage.tag= i;
i++;
UIGraphicsEndImageContext();
[self.view addSubview:myImage];
[arrayOfImages addObject:myImage];
[myImage setUserInteractionEnabled:YES];
}
}
所有我想的是,如果我點擊它應檢查是否有已經UIImageView的在那個地方畫的按鈕,然後它繪製的UIImageView有點遠離它。
我將不勝感激,如果你幫我一些代碼。
因爲它依賴於用戶,然後他什麼時候按一下按鈕,如何將我能調整我的runtime.If的UIImageViews的地方ü可以給我這樣的代碼什麼的一些例子。 – Hanny 2011-03-07 11:10:33
