调取本地图片传输到其他的页面,在方法
- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info; 中,info为字典值,期中包含你所选择的图片的URL值,可以通过URL值进行传值操作,下面为具体代码:
.h文件
#import <UIKit/UIKit.h>
//签订协议
@interface ViewController : UIViewController<UINavigationControllerDelegate,UIImagePickerControllerDelegate>
@end
.m文件
#import "ViewController.h"
@interface ViewController ()
@end
@implementation ViewController
- (void)viewDidLoad {
[super viewDidLoad];
UIImageView *imageView = [[UIImageView alloc] init];
imageView.frame = CGRectMake(80, 50, 200, 120);
imageView.backgroundColor = [UIColor greenColor];
imageView.tag = 1001;
[self.view addSubview:imageView];
UIButton *button = [UIButton buttonWithType:UIButtonTypeRoundedRect];
button.frame = CGRectMake(0, 200, 100, 30);
[button setTitle:@"打开相册" forState:UIControlStateNormal];
[button addTarget:self action:@selector(openPics) forControlEvents:UIControlEventTouchUpInside];
[self.view addSubview:button];
UIButton *button2 = [UIButton buttonWithType:UIButtonTypeRoundedRect];
button2.frame = CGRectMake(0, 300, 100, 30);
[button2 setTitle:@"打开相机" forState:UIControlStateNormal];
[button2 addTarget:self action:@selector(openCamera) forControlEvents:UIControlEventTouchUpInside];
[self.view addSubview:button2];
}
// 打开相机
- (void)openCamera {
// UIImagePickerControllerCameraDeviceRear 后置摄像头
// UIImagePickerControllerCameraDeviceFront 前置摄像头
BOOL isCamera = [UIImagePickerController isCameraDeviceAvailable:UIImagePickerControllerCameraDeviceRear];
if (!isCamera) {
NSLog(@"没有摄像头");
return ;
}
UIImagePickerController *imagePicker = [[UIImagePickerController alloc] init];
imagePicker.sourceType = UIImagePickerControllerSourceTypeCamera;
imagePicker.delegate = self;
// 编辑模式
imagePicker.allowsEditing = YES;
[self presentViewController:imagePicker animated:YES completion:^{

}
// 打开相册
- (void)openPics {
UIImagePickerController *imagePicker = [[UIImagePickerController alloc] init];
imagePicker.sourceType = UIImagePickerControllerSourceTypePhotoLibrary;
imagePicker.delegate = self;
imagePicker.allowsEditing =YES;
[self presentViewController:imagePicker animated:YES completion:^{

}
// 选中照片
- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info{
NSLog(@"%@", info);
UIImageView *imageView = (UIImageView *)[self.view viewWithTag:1001];
// UIImagePickerControllerOriginalImage 原始图片
// UIImagePickerControllerEditedImage 编辑后图片
UIImage *image = [info objectForKey:UIImagePickerControllerEditedImage];
imageView.image = image;
[picker dismissViewControllerAnimated:YES completion:NULL];
}
// 取消相册
