IOS应用开发，如何加载图片库中的Image到view中？下面我们来学习一下吧！
操作步骤：
1.创建一个SingleView的项目，然后启动模拟器，点击模拟器上的浏览器，然后将本地的图片拖放上去，然后点击图片长按，点击saveImage到图片库。
2.修改ViewController
ViewController.h:
#import <UIKit/UIKit.h> @interface DXWViewController : UIViewController<UIImagePickerControllerDelegate,UINavigationControllerDelegate> @property (retain, nonatomic) IBOutlet UIImageView *imageView; @property (retain, nonatomic) IBOutlet UIButton *Button; @property(retain,nonatomic) UIImage *image; - (IBAction)click:(id)sender; @end
ViewController.m:
#import "DXWViewController.h"
@interface DXWViewController ()
@end
@implementation DXWViewController
- (void)viewDidLoad
{
[super viewDidLoad];
}
-(void)viewWillAppear:(BOOL)animated
{
self.imageView.image = self.image;
}
//加载成功
-(void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info
{
self.Image = [info objectForKey:UIImagePickerControllerEditedImage];
[picker dismissViewControllerAnimated:YES completion:nil];
}
//取消
-(void)imagePickerControllerDidCancel:(UIImagePickerController *)picker
{
[picker dismissViewControllerAnimated:YES completion:nil];
}
- (void)dealloc {
[_imageView release];
[_image release];
[_Button release];
[super dealloc];
}
//打开图库获取图片
- (IBAction)click:(id)sender {
if ([UIImagePickerController isSourceTypeAvailable:UIImagePickerControllerSourceTypePhotoLibrary]) {
UIImagePickerController *picker = [[UIImagePickerController alloc] init];
picker.sourceType = UIImagePickerControllerSourceTypePhotoLibrary;
picker.delegate = self;
picker.allowsEditing = YES;
[self presentViewController:picker animated:YES completion:nil];
}
}
@end
