- UIImagePickerController 编辑/选取图片时
最近测试报出来，当双击选择照片时，就会触发2次点击事件，调查发现确实触发了2次代理方法，
原代码
- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info
{
// 业务处理逻辑
[self doSomeWorking];
picker.delegate = nil;
[picker dismissViewControllerAnimated:YES completion:nil];
}
解决方法如下
- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info
{
// 先将代理置空，防止触发多次。
picker.delegate = nil;
[picker dismissViewControllerAnimated:YES completion:nil];
// 业务处理逻辑
[self doSomeWorking];
}
