本文修改了来自网络上旧代码中一些不再被推荐使用的方法。
废话不多说，直接上代码！以下代码均为.m源文件
#import "ViewController.h"
@interface ViewController ()<UIImagePickerControllerDelegate,UINavigationControllerDelegate>
@end
@implementation ViewController
- (void)viewDidLoad {
[superviewDidLoad];
UIButton *takePhoto = [UIButtonbuttonWithType:UIButtonTypeRoundedRect];
[takePhoto setTitle:@"录像"forState:UIControlStateNormal];
[takePhoto addTarget:selfaction:@selector(takePhoto)forControlEvents:UIControlEventTouchUpInside];
takePhoto.frame = CGRectMake(50,100,100,30);
[self.view addSubview:takePhoto];
}
- (void)didReceiveMemoryWarning {
[superdidReceiveMemoryWarning];
}
-(void)takePhoto
{
UIImagePickerControllerSourceType sourceType=UIImagePickerControllerSourceTypeCamera;
if (![UIImagePickerControllerisSourceTypeAvailable:UIImagePickerControllerSourceTypeCamera]) {
sourceType=UIImagePickerControllerSourceTypePhotoLibrary;
}
UIImagePickerController * picker = [[UIImagePickerControlleralloc]init];
picker.delegate=self;
picker.allowsEditing=YES;
picker.sourceType=sourceType;
[selfpresentViewController:pickeranimated:YEScompletion:nil];
}
-(void)saveImage:(UIImage*)image
{
NSLog(@"保存");
}
-(void)imagePickerController:(UIImagePickerController*)picker didFinishPickingMediaWithInfo:(NSDictionary *)info
{
[picker dismissViewControllerAnimated:YEScompletion:nil];
UIImage * image=[info objectForKey:UIImagePickerControllerEditedImage];
[selfperformSelector:@selector(saveImage:)withObject:imageafterDelay:0.5];
}
-(void)imagePickerControllerDIdCancel:(UIImagePickerController*)picker
{
[picker dismissViewControllerAnimated:YEScompletion:nil];
}
真机亲测可用，能进行调焦距。
