目前我正在一个多语言的应用程序，我想改变Cancel ， Use和Retake的按钮标题UIImagePickerController 。 我怎样才能做到这一点？
Answer 1:
我的问题是通过使用自定义覆盖类解决。
self.picker = [[UIImagePickerController alloc] init];
self.picker.sourceType = UIImagePickerControllerSourceTypeCamera;
self.picker.cameraCaptureMode = UIImagePickerControllerCameraCaptureModePhoto;
self.picker.cameraDevice = UIImagePickerControllerCameraDeviceRear;
self.picker.showsCameraControls = NO;
self.picker.navigationBarHidden = YES;
self.picker.toolbarHidden = YES;
self.picker.wantsFullScreenLayout = YES;
// Insert the overlay
self.overlay = [[OverlayViewController alloc] initWithNibName:@"Overlay" bundle:nil];
self.overlay.pickerReference = self.picker;
self.picker.cameraOverlayView = self.overlay.view;
self.picker.delegate = self.overlay;
[self presentModalViewController:self.picker animated:NO];
Answer 2:
只需添加所需的本地化在您的项目：
1）选择工程文件;
2）在“项目和目标”列表中选择您的项目;
3）选择“信息”（在屏幕的顶部部分）;
4）在“本地化”部分添加需要的语言。
Answer 3:
它会自动转换为设备语言。
你不需要这个Ø担心。 此外，你不能改变它的行为。
控制喜欢： MFMessageComposer ， MFMailComposer ， UIImagePicker等都会发生变化，将自动默认控件文本的设备语言。
Answer 4:
指定委托作为自我的imagepicker控制器并添加以下代码：
- (void)navigationController:(UINavigationController *)navigationController willShowViewController:(UIViewController *)viewController animated:(BOOL)animated {
UINavigationItem *ipcNavBarTopItem;
// add done button to right side of nav bar
UIBarButtonItem *doneButton = [[UIBarButtonItem alloc] initWithTitle:@\"Done\"
style:UIBarButtonItemStylePlain
target:self
action:@selector(saveImages:)];
UINavigationBar *bar = navigationController.navigationBar;
[bar setHidden:NO];
ipcNavBarTopItem = bar.topItem;
ipcNavBarTopItem.title = @\"Pick Images\";
ipcNavBarTopItem.rightBarButtonItem = doneButton;
}
Answer 5:
这是所有一堆垃圾。 只有很好的解决办法是在这里...
//this is your camera method
- (void)startCameraControllerUsingDelegate:(id<UIImagePickerControllerDelegate, UINavigationControllerDelegate>)delegate gallery:(BOOL)openGallery
{
if (([UIImagePickerController isSourceTypeAvailable:UIImagePickerControllerSourceTypeCamera] == NO)
|| (delegate == nil))
return;
UIImagePickerController *cameraUI = [[UIImagePickerController alloc] init];
if (openGallery) {
cameraUI.sourceType = UIImagePickerControllerSourceTypePhotoLibrary;
} else {
cameraUI.sourceType = UIImagePickerControllerSourceTypeCamera;
}
cameraUI.allowsEditing = YES;
//set your delegate type UINavigationControllerDelegate here! It will trigger function bellow!
cameraUI.delegate = delegate;
[self presentViewController:cameraUI animated:YES completion:nil];
}
//UINavigationControllerDelegate function
- (void)navigationController:(UINavigationController *)navigationController willShowViewController:(UIViewController *)viewController animated:(BOOL)animated
{
//this is where magic happends! This leaves button empty and it will not ruin title center position!... or give it your desired string
viewController.navigationItem.backBarButtonItem = [[UIBarButtonItem alloc] initWithTitle:@"" style:UIBarButtonItemStylePlain target:nil action:nil];
}
Answer 6:
只要找到和改变的UIButton的文本
-(void)navigationController:(UINavigationController *)navigationController willShowViewController:(UIViewController *)viewController animated:(BOOL)animated
{
for (UIView *v in viewController.view.subviews)
{
if ([v isKindOfClass:[NSClassFromString(@"CMKBottomBar") class]])
{
SEL se = NSSelectorFromString(@"cancelButton");
if ([v respondsToSelector:se])
{
UIButton *cancelButton = [v performSelector:se];
[cancelButton setTitle:@"New title" forState:UIControlStateNormal];
}
}
}
}
