iCarousel 不显示我的图片 objective C
iCarousel doesn't show my images objective C
我想使用 iCarousel 在视图控制器中显示多个图像。
我在 NSMutableArray 中列出了我所有的图像 foto,
然后我在 iCarousel 方法中调用数组照片 viewForItemAtIndex.
我已经按照一些教程进行操作，但仍然无法正常工作。
请帮我。
这是我的 .m 代码
#import "TestController.h"
@interface TestController () <UIActionSheetDelegate>
@property (nonatomic, retain) NSMutableArray *foto;
@end
@implementation TestController
@synthesize carousel;
@synthesize foto;
- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil
{
self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil];
if (self) {
// Custom initialization
foto = [NSArray arrayWithObjects:
[UIImage imageNamed:@"Seleb1.jpg"],
[UIImage imageNamed:@"Seleb2.jpg"],
[UIImage imageNamed:@"Seleb3.jpg"],
nil];
}
return self;
}
- (void)dealloc
{
carousel.delegate = nil;
carousel.dataSource = nil;
}
- (void)viewDidLoad
{
[super viewDidLoad];
carousel.type = iCarouselTypeCoverFlow2;
}
- (void)viewDidUnload
{
[super viewDidUnload];
self.carousel = nil;
}
#pragma mark -
#pragma mark iCarousel methods
- (NSUInteger)numberOfItemsInCarousel:(iCarousel *)carousel
{
return [foto count];
}
- (UIView *)carousel:(iCarousel *)carousel viewForItemAtIndex:(NSUInteger)index reusingView:(UIView *)view
{
view = [[UIImageView alloc] initWithImage:[UIImage imageNamed:[foto objectAtIndex:index]]];
return view;
}
@end
有人可以帮助我吗？
我的代码有什么问题？

更改此行
view = [[UIImageView alloc] initWithImage:[UIImage imageNamed:[foto objectAtIndex:index]]];
到
Reason : you have already defined your array as [UIImage imageNamed:@"Seleb1.jpg"] , so in here you need call directly like
view = [[UIImageView alloc] initWithImage:[foto objectAtIndex:index]];
选择-2
创建一个类似
的数组
foto = [NSArray arrayWithObjects:
@"Seleb1.jpg",
@"Seleb2.jpg",
@"Seleb3.jpg",
nil];
并像
一样打电话
view = [[UIImageView alloc] initWithImage:[UIImage imageNamed:[foto objectAtIndex:index]]];
如果你需要
使用这个
- (void)viewDidLoad
{
[super viewDidLoad];
carousel.type = iCarouselTypeCoverFlow2;
[carousel reloadData];
}

@TomKnapen : where should i set it ? if it's on the story board, i've
set it already. in the TestController.h, i've set it too here's my
code in .h : TestController : UIViewController – Shasapo
我不确定你是如何在故事板中设置它的，但在代码中，你没有设置委托。此行没有设置委托 TestController : UIViewController <iCarouselDataSource,iCarouselDelegate>，它的作用是使您的控制器（在本例中为 TestController）遵守 iCarouselDelegate 协议。您需要做的是在 viewDidLoad 中显式设置委托和数据源，例如
carousel.delegate = self;
carousel.datasource = self;
2 - 首先尝试调试那些委托方法。从 nimberOfItems 方法开始，检查 foto 数组是否为 nil。然后在 viewForItem 方法中检查您 return 的图像是否不为零。
因为您使用的是故事板，所以您的 initWithNibName 方法没有被调用，这就是为什么您的照片数组没有被初始化，我假设。在我看来，您的 numberofitems 方法 returns 0。尝试在此方法中放置断点并查看，或者仅添加 NSLog 语句并检查 foto 数组是否为 nil
3 - 您没有将 iCarousel 视图添加到您的视图中。
我过去使用过这个框架，所以我决定包含我实现的代码片段

self.projectsTableview.tag = tableTag++;
return self.projectsTableview; }
