iCarousel不会加载图像
问题描述:
因此,我试图使用iCarousel以图像的形式显示产品,然后用户可以简单地滚动并查看所有可用的产品。iCarousel不会加载图像
因为当您加载视图 - 控制它根本不会显示任何图像,甚至表现出传送带某些原因,我用它为int等
我的代码遵循的号码时之前曾:
ApparelViewController.m
#import "ApparelViewController.h"
@interface ApparelViewController()
@property (nonatomic, strong) NSMutableArray *images;
@end
@implementation ApparelViewController
@synthesize carouselView = _carouselView;
@synthesize images = _images;
- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil
{
if ((self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil]))
{
//get image paths
NSArray *imagePaths = [[NSBundle mainBundle] pathsForResourcesOfType:@"png" inDirectory:@"Products"];
//preload images (although FXImageView can actually do this for us on the fly)
_images = [[NSMutableArray alloc] init];
for (NSString *path in imagePaths)
{
[_images addObject:[UIImage imageWithContentsOfFile:path]];
}
}
return self;
}
- (void)dealloc
{
//it's a good idea to set these to nil here to avoid
//sending messages to a deallocated viewcontroller
_carouselView.delegate = nil;
_carouselView.dataSource = nil;
}
- (void)viewDidLoad {
[super viewDidLoad];
self.view.backgroundColor = [UIColor colorWithRed:236/255 green:240/255 blue:241/255 alpha:1];
// Do any additional setup after loading the view.
_carouselView.type = iCarouselTypeRotary;
}
- (void)viewDidUnload
{
[super viewDidUnload];
//free up memory by releasing subviews
self.carouselView = nil;
}
- (NSInteger)numberOfItemsInCarousel:(iCarousel *)carousel
{
return [_images count];
}
- (UIView *)carousel:(iCarousel *)carousel viewForItemAtIndex:(NSInteger)index reusingView:(UIView *)view
{
if (view == nil)
{
FXImageView *imageView = [[FXImageView alloc] initWithFrame:CGRectMake(0, 0, 200.0f, 200.0f)];
imageView.contentMode = UIViewContentModeScaleAspectFit;
imageView.asynchronous = YES;
imageView.reflectionScale = 0.5f;
imageView.reflectionAlpha = 0.25f;
imageView.reflectionGap = 10.0f;
imageView.shadowOffset = CGSizeMake(0.0f, 2.0f);
imageView.shadowBlur = 5.0f;
imageView.cornerRadius = 10.0f;
view = imageView;
}
//show placeholder
((FXImageView *)view).processedImage = [UIImage imageNamed:@"page.png"];
((FXImageView *)view).image = _images[index];
return view;
}
- (void)didReceiveMemoryWarning {
[super didReceiveMemoryWarning];
// Dispose of any resources that can be recreated.
}
- (IBAction)goBack:(id)sender {
NSString * storyboardName = @"Main";
UIStoryboard *storyboard = [UIStoryboard storyboardWithName:storyboardName bundle: nil];
UIViewController * vc = [storyboard instantiateViewControllerWithIdentifier:@"navBar"];
[self presentViewController:vc animated:YES completion:nil];
}
@end
然后在ApparelViewController.h
文件我有以下代码:
#import <UIKit/UIKit.h>
#import "iCarousel.h"
#import "FXImageView.h"
@interface ApparelViewController : UIViewController <iCarouselDelegate, iCarouselDelegate>
@property (strong, nonatomic) IBOutlet UIButton *backButton;
@property (strong, nonatomic) IBOutlet iCarousel *carouselView;
@end
真的很烦人的是我之前使用过iCarousel,但对于Swift,所以我知道它是如何工作的,但我不知道Obj-C那么好!
关于如何去显示图像的任何想法?
答
你可以检查有几件事情,
- 检查“图像”是返回比“numberOfItemsInCarousel” 0伟大的,很明显,但值得一试的值。
- 检查图像是否实际加载,即检查图像[index]实际加载图像。
- 我并不熟悉FXImageView,但尝试使用
(void)setImage:(UIImage *)image;
而不是分配@property (nonatomic, strong) UIImage *image;
。该文件说,.image实际上不设置图像,但添加效果。
如果这些都不能解决您的问题,请评论,我会继续寻找,祝你好运。
我已经尝试了很多东西,包括你的建议和运气:(有没有机会,也许你可以尝试使用iCarousel创建一个项目,看看你是否可以得到它显示不同的图像请 – Konsy
