응용 프로그램의 특정 부분에서 사용자가 카메라에서 사진을 찍거나 앨범에서 사진을 찍을 수 있으며이 이미지가 표시됩니다. ViewController에. 이것은 쉽지만, 내가 할 수없는 일은 다음과 같습니다. - 카메라를 전체 화면으로 열지 않고 ViewController에서 '열어'싶습니다. 사용자는 이미지가있는 곳과 정확히 같은 곳에 원 안에 있습니다. 카메라를 전체 화면으로 열 수 없도록 만들었지 만이보기를 원보기 안에 넣고 원에 따라 사진을자를 수는 없습니다. 여기 사용자 정의 카메라가 전체 화면이 아닌 UIView에 있음
는 표준 프로젝트를 만드는 경우가 작동하지 않을 수 있습니다, 내 코드와 나는 그에서 무슨 일이 일어나고 있는지 이해하는 데 도움이 될 것입니다 생각 :@property (nonatomic, strong) UIImagePickerController * picker;

는 fullcode입니까? – mbm29414앨범에서 사진을 찍거나 사진을 선택하여 내 화면에 표시 할 수 있습니다 (서클/자르기에 맞게 편집하지 않아도 됨). –
코드가 업데이트되었습니다. 이제 이미지는 괜찮지 만 조금 올라간다. –
