and Retake
button titles of the UIImagePickerController
. 目前我正在开发一个多语言应用程序,我想更改
UIImagePickerController
的Cancel
, Use
和Retake
按钮标题。 How can I do that? 我怎样才能做到这一点?
My problem is solved by using custom overlay class. 我的问题是通过使用自定义覆盖类解决的。
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];
Just add needed localizations in your project: 只需在项目中添加所需的本地化:
1) Select project file; 1)选择工程文件;
2) Select your project in "Project and Targets" list; 2)在“项目和目标”列表中选择项目;
3) Select "Info" (in top part of screen); 3)选择“信息”(在屏幕顶部);
4) Add needed languages in "Localizations" section. 4)在“本地化”部分中添加所需的语言。
It'll be automatically changed to device language. 它会自动更改为设备语言。
You don't need o worry about this. 你不需要担心这个。 Also you can't change it's behavior.
你也无法改变它的行为。
Controls like: MFMessageComposer
, MFMailComposer
, UIImagePicker
etc. Will change it's default controls text to device language automatically. 诸如
MFMessageComposer
, MFMailComposer
, UIImagePicker
等控件。将默认控件文本自动更改为设备语言。
Assign delegate as self to your imagepicker controller and add the following code : 将委托作为self分配给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;
}
Only good solution is here... 这里只有好的解决方案...
//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];
}
Just find and change text of UIButton 只需查找并更改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];
}
}
}
}
