我希望有人可以在这里帮助我,我不知道还能做什么。我有一个 UIScrollView 加载一组 44 图像,然后允许用户翻阅它们。我的代码正在工作,然后突然停止了。我不知道我做了什么改变,所以任何帮助将不胜感激:
前一个视图是一个 UITableView,它传递一个字符串以及所选单元格的名称。这是 ScrollView 中的 ViewDidLoad 方法:
- (void)viewDidLoad
{
[super viewDidLoad];
UIBarButtonItem *rightButton = [[UIBarButtonItem alloc] initWithTitle:@"Answer"
style:UIBarButtonItemStyleBordered
target:self
action:@selector(answerPressed:)];
self.navigationItem.rightBarButtonItem = rightButton;
if([questionSetName isEqualToString:@"Limitations"]){
[self limitationsView];
}
}
这是限制视图:
-(void)limitationsView{
UIScrollView *scroll = [[UIScrollView alloc] initWithFrame:CGRectMake(0, -44, self.view.frame.size.width, self.view.frame.size.height)];
scroll.pagingEnabled = YES;
NSArray *unsortedArray = [[NSBundle mainBundle] pathsForResourcesOfType:@"png" inDirectory:@"Images/Limitations"];
NSMutableArray *limitationImages = [[NSMutableArray alloc] init];
for (int x = 0; x<[unsortedArray count]; x++) {
NSString *fileName = [[unsortedArray objectAtIndex:x] lastPathComponent];
[limitationImages insertObject:fileName atIndex:x];
}
NSArray *sortedArray = [limitationImages sortedArrayUsingFunction:finderSortWithLocal
context:(__bridge void *)([NSLocale currentLocale])];
for(int i = 0; i< [sortedArray count]; i++){
CGFloat xOrigin = i * self.view.bounds.size.width;
UIImageView *limitationImageView = [[UIImageView alloc] initWithFrame:CGRectMake(xOrigin, 0, self.view.frame.size.width, self.view.frame.size.height)];;
[limitationImageView setImage:[UIImage imageNamed:[sortedArray objectAtIndex:i]]];
limitationImageView.contentMode = UIViewContentModeScaleAspectFit;
[scroll addSubview:limitationImageView];
}
scroll.contentSize = CGSizeMake(self.view.frame.size.width * [sortedArray count], self.view.frame.size.height);
[self.view addSubview:scroll];
}
当我到达 LimitationsView 方法的末尾时,sortedArray 包含所有 44 个图像和正确的名称,如果我尝试设置滚动视图的背景颜色,我可以成功地做到这一点。但是我的图像没有加载,我不知道为什么?
