iOS图片浏览功能
Qu_qipa 人气:0这是整体的效果图:
其中main.stroyboard中的控件有2个button,2个label,一个imageView。
设置他们的位置大小和背景颜色和图片。
让main.storyboard连接ViewController.m
下面是它的代码:
#import "ViewController.h" @interface ViewController () @property (weak, nonatomic) IBOutlet UILabel *topLabel; @property (weak, nonatomic) IBOutlet UILabel *descLabel; @property (weak, nonatomic) IBOutlet UIButton *leftBtn; @property (weak, nonatomic) IBOutlet UIButton *rightBtn; @property (weak, nonatomic) IBOutlet UIImageView *imageView; @property (nonatomic, assign) int index; @property (nonatomic, strong) NSArray *imageDicts; @end @implementation ViewController - (NSArray *)imageDicts { if (!_imageDicts) { NSString *path = [[NSBundle mainBundle] pathForResource:@"imageDate.plist" ofType:nil]; _imageDicts = [NSArray arrayWithContentsOfFile:path]; } return _imageDicts; } - (IBAction)leftBtnOnClick:(UIButton *)sender { self.index --; [self btnClickChange]; } - (IBAction)rightBtnOnClick:(id)sender { self.index ++; [self btnClickChange]; } - (void)btnClickChange { self.topLabel.text = [NSString stringWithFormat:@"%d/%d", (self.index + 1), self.imageDicts.count]; self.descLabel.text = self.imageDicts[self.index][@"description"]; self.imageView.image = [UIImage imageNamed:self.imageDicts[self.index][@"name"]]; self.leftBtn.enabled = (self.index != 0); self.rightBtn.enabled = (self.index != 4); } - (void)viewDidLoad { [super viewDidLoad]; // Do any additional setup after loading the view, typically from a nib. } - (void)didReceiveMemoryWarning { [super didReceiveMemoryWarning]; // Dispose of any resources that can be recreated. } @end
这样就完成了一个简单的图片浏览的应用。
