我的应用程序中有一部分用户可以快速拍摄照片并将其保存到相机胶卷中。我的唯一的一点是，在拍完照片后，它会使用方形裁剪器进入屏幕（我猜它就是这样），然后在底部显示“重拍”和“使用照片”。我希望使用照片说“保存照片”（无论如何它都是这样）。反正有没有这样做？ 这是我的代码
- (IBAction)takePhoto:(UIButton *)sender {
UIImagePickerController *picker = [[UIImagePickerController alloc] init];
picker.delegate = self;
picker.allowsEditing = YES;
picker.sourceType = UIImagePickerControllerSourceTypeCamera;
[self presentViewController:picker animated:YES completion:NULL];
}
- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info {
UIImage *chosenImage = info[UIImagePickerControllerEditedImage];
self.imageView.image = chosenImage;
UIImageWriteToSavedPhotosAlbum(chosenImage, nil, nil, nil);
[picker dismissViewControllerAnimated:YES completion:NULL];
}
- (void)imagePickerControllerDidCancel:(UIImagePickerController *)picker {
[picker dismissViewControllerAnimated:YES completion:NULL];
}

您可以将取消按钮更改为您想要的任何标题：
在viewController中添加以下代码：
- (void)navigationController:(UINavigationController *)navigationController willShowViewController:(UIViewController *)viewController animated:(BOOL)animated {
[[UIApplication sharedApplication] setStatusBarHidden:YES];
[self changeCancelToAnythingUWantOf:viewController andReplacementString:@"Your Replacement String"];
}
- (void)changeCancelToAnythingUWantOf:(UIViewController*)vc andReplacementString:(NSString*)title {
for(UIView *subView in vc.view.subviews) {
if ([subView isKindOfClass:[UIButton class]]) {
UIButton *btn = (UIButton *)subView;
if([btn.titleLabel.text isEqualToString:@"Cancel"]) {
[btn setTitle:title forState:UIControlStateNormal];
break;
}
}
if (subView.subviews) {
for (UIView *subSubView in subView.subviews) {
if ([subSubView isKindOfClass:[UIButton class]]) {
UIButton *btn = (UIButton *)subSubView;
if([btn.titleLabel.text isEqualToString:@"Cancel"]) {
[btn setTitle:title forState:UIControlStateNormal];
break;
}
}
if (subSubView.subviews) {
for (UIView *subSubSubView in subSubView.subviews) {
if ([subSubSubView isKindOfClass:[UIButton class]]) {
UIButton *btn = (UIButton *)subSubSubView;
if([btn.titleLabel.text isEqualToString:@"Cancel"]) {
[btn setTitle:title forState:UIControlStateNormal];
break;
}
}
}
}
}
}
}
}

你可以通过recusrion方式找到它
func buttonWithTitle(forView view: UIView, title: String) -> UIButton? {
guard view.subviews.count > 0 else { return nil }
var needButton: UIButton? = nil
for subview in view.subviews {
if subview is UIButton {
let button = subview as! UIButton
if button.titleLabel?.text == title {
return button
}
}
needButton = buttonWithTitle(forView: subview, title: title)
if needButton != nil { return needButton }
}
return needButton
}
