doesn't work correctly. addSubview problem
Help me. addSubview doesn't work. I want to add "ContentView" on scrollView. But "ContentView" doesn't appear on screen. "ContentView" is UIView.
When I change to self.view=scrollView from [self.view addSubview:scrollView], addSubview doesn't work.
Please teach me how to add UIView on this screen!!
- (void)viewDidLoad {
[super viewDidLoad];
scrollViewMode = ScrollViewModeNotInitialized;
mode = 1;
imageViewArray = [[NSMutableArray alloc] init];
mainStatic = [[MainStatics alloc] init];
[mainStatic setSetting];
NSString* path = [[NSBundle mainBundle] pathForResource:@"Files" ofType:@"plist"];
NSArray* dataFiles = [NSArray arrayWithContentsOfFile:path];
kNumImages = [dataFiles count];
CGRect frame = [UIScreen mainScreen].applicationFrame;
scrollView = [[touchClass alloc] initWithFrame:frame];
scrollView.delegate = self;
scrollView.maximumZoomScale = 5.0f;
scrollView.minimumZoomScale = 1.0f;
[scrollView setBackgroundColor:[UIColor blackColor]];
[scrollView setDelegate:self];
scrollView.delaysContentTouches=NO;
scrollView.userInteractionEnabled = YES;
[scrollView setCanCancelContentTouches:NO];
NSUInteger i;
for (i=0;i<[dataFiles count];i++)
{
UIImage* image = [UIImage imageNamed:[dataFiles objectAtIndex:i]];
UIImageView *imageView = [[UIImageView alloc] initWithImage:image];
imageView.contentMode = UIViewContentModeScaleAspectFit;
imageView.userInteractionEnabled = NO;
CGRect rect = imageView.frame;
rect.size.height = 480;
rect.size.width = 320; 开发者_开发技巧
imageView.frame = rect;
imageView.tag = i+1;
[imageViewArray addObject:imageView];
}
self.view = scrollView;
[self setPagingMode];
UIView* contentView;
CGRect scRect = CGRectMake(0, 436, 320, 44);
contentView = [[UIView alloc] initWithFrame:scRect];
[contentView addSubview:toolView];
[self addSubview:contentView];
}
I used image array in following function. toolView is UIView with UIToolbar. So I want to add toolbar to screen. Yes, touchClass is subclass of UIScrollView. 1.I see.I forgot release this.Thank you. 2.OK. I modified this.But "ContentView" didn't apear.
are there another reason?
- (void)setPagingMode {
CGSize pageSize = [self pageSize];
NSUInteger page = 0;
for (UIView *view in imageViewArray){
[scrollView addSubview:view];
view.frame = CGRectMake(pageSize.width * page++, 0, pageSize.width, pageSize.height);
}
scrollView.pagingEnabled = YES;
scrollView.showsVerticalScrollIndicator = scrollView.showsHorizontalScrollIndicator = YES;
scrollView.contentSize = CGSizeMake(pageSize.width * [imageViewArray count], pageSize.height);
scrollView.contentOffset = CGPointMake(pageSize.width * currentPage, 0);
scrollViewMode = ScrollViewModePaging;
}
Source isn't clear.
You never use array with UIImageView. There is no info what is toolView etc...
Please provide more detailed source. Is touchClass
a subclass of UIScrollView
?
What I noticed in your code:
- You don't release
image
andimageView
. All this images imageViews will be leaked. At the end of loop you should add[imageView release];
and[image release];
- I don't think that it is good idea to send
[self addSubview:contentView];
Try to use[self.view addSubview:contentView];
