我的应用程序崩溃，同时使用3个视图，每个视图包含12个按钮，这些按钮使用相同的图像，但每次使用不同的颜色，所以我使用
-(void) addViewsToscroll
{
NSMutableArray *imgArray = [[NSMutableArray alloc] init];
[imgArray addObject:FirstView];
[imgArray addObject:secondView];
[imgArray addObject:ThirdView];
CGSize pageSize = scrollView.frame.size; // scrollView is an IBOutlet for our UIScrollView
NSUInteger page = 0;
for(UIView *view in imgArray) {
[scrollView addSubview:view];
// This is the important line
view.frame = CGRectMake(pageSize.width * page++ +3, 0, pageSize.width-6 , pageSize.height);
// We're making use of the scrollView's frame size (pageSize) so we need to;
// +10 to left offset of image pos (1/2 the gap)
// -20 for UIImageView's width (to leave 10 gap at left and right)
}
scrollView.contentSize = CGSizeMake(pageSize.width * [imgArray count], pageSize.height);
}
-(void) setButtonsColor{
NSString *localPath = [NSHomeDirectory() stringByAppendingPathComponent:@"Documents"];
NSString *imageBouton1 = [localPath stringByAppendingPathComponent:[[NSString alloc]initWithFormat:@"%ld-shapeDisplayUrl.png",(long)button.tag]];
NSData *imgData = [[NSData alloc] initWithContentsOfURL:[NSURL fileURLWithPath: imageBouton1]];
if (imgData == nil)
{
}else
{
UIImage *tintedImage = [[[UIImage alloc] initWithData:imgData] imageWithRenderingMode:UIImageRenderingModeAlwaysTemplate];
[button setImage:tintedImage forState:UIControlStateNormal];
button.tintColor=color1;
button.backgroundColor = color2;
}
}
但是当imaged分配给按钮并且颜色改变时，如果我从视图滚动到视图应用程序崩溃。
感谢您的帮助
