总会遇到一些应用 要拍照 设置图片之类的的 总结一个方法备用 以后 会 继续拓展到 多图
@interface AddCustomerViewController : UIViewController<UIImagePickerControllerDelegate,UINavigationControllerDelegate>
{
UIImage *chosenImage;//做显示在self.view 上的image
NSString *tempImagePath;//图片路径
UIButton *button_Photo;//点击从系统选图片
}
@end
//以上代理 和参数 都是必须有的
-(void)TakePhoto
{
UIActionSheet *actionSheet =[[UIActionSheet alloc]initWithTitle:@"您想如何获取照片?" delegate:self cancelButtonTitle:@"取消" destructiveButtonTitle:nil otherButtonTitles:@"拍照", nil];
[actionSheet showInView:self.view];
}
-(void)actionSheet:(UIActionSheet *)actionSheet clickedButtonAtIndex:(NSInteger)buttonIndex
{
/*
NSLog(@"%ld",(long)buttonIndex);//2--->取消
UIImagePickerController *picker = [[UIImagePickerController alloc] init];
picker.delegate = self;
picker.allowsEditing = YES;
if(buttonIndex==0)
{//拍照
picker.sourceType=UIImagePickerControllerSourceTypeCamera;
}
else if(buttonIndex==1)
{//图库
picker.sourceType = UIImagePickerControllerSourceTypePhotoLibrary;
}
[self presentViewController:picker animated:YES completion:NULL];
*/
NSLog(@"%ld",(long)buttonIndex);//2--->取消 if(buttonIndex==)
{//拍照
UIImagePickerController *picker = [[UIImagePickerController alloc] init];
picker.delegate = self;
picker.allowsEditing = YES;
picker.sourceType=UIImagePickerControllerSourceTypeCamera;
[self presentViewController:picker animated:YES completion:NULL];
} } #pragma -mark UIImagePickerController delegate
-(void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info
{
chosenImage = [info objectForKey:@"UIImagePickerControllerOriginalImage"];
//删除缓存文件
if ([[NSFileManager defaultManager] fileExistsAtPath:tempImagePath]) {
NSLog(@"the image is exist");
NSFileManager *defaultManager; defaultManager = [NSFileManager defaultManager];
NSError *error = [[NSError alloc] init];
[defaultManager removeItemAtPath:tempImagePath error:&error]; }
[UIImagePNGRepresentation(chosenImage) writeToFile:[ NSTemporaryDirectory() stringByAppendingPathComponent:@"temp_image.png"] atomically:YES]; BOOL fileExists = [[NSFileManager defaultManager] fileExistsAtPath:tempImagePath]; if (fileExists) {
NSLog(@"success");
customer_Inform.image_Head=chosenImage;
[button_Photo setImage:chosenImage forState:UIControlStateNormal]; }
[picker dismissViewControllerAnimated:YES completion:NULL]; if (fileExists) {
NSLog(@"success");
[SGInfoAlert showInfo:@" 照片添加成功! "
bgColor:[[UIColor darkGrayColor] CGColor]
inView:self.view
vertical:0.5];
}
else
{
[SGInfoAlert showInfo:@" 照片添加不成功! "
bgColor:[[UIColor darkGrayColor] CGColor]
inView:self.view
vertical:0.5];
}
// //也能用
// [button_Photo setImage:[info objectForKey:@"UIImagePickerControllerOriginalImage"] forState:UIControlStateNormal];
// [picker dismissViewControllerAnimated:YES completion:NULL];
