今天調用系統的照相和本地相冊，編輯圖片的功能，但是按鈕都是英文，我想改為中文的 取消，選擇，重拍

需要改變兩種方法

1. UIImagePickerController頁面的Cancel和Choose按鈕以及截取中得重拍按鈕，想改成中文

本來打算通過獲取這些按鈕的指針進行設置的，最後發現可以在工程中直接 project-->info-->Localization--->language中add一個簡體中文就可以了

參考：http://www.cocoachina.com/bbs/read.php?tid=132828

2.定制當然也有方法

首先通過遞歸的方法不斷地在self.view的hierarchy中不斷遍歷，直到查找到這個view，獲取其指針進行操作

-(UIView *)findView:(UIView *)aView withName:(NSString *)name{
    Class cl = [aView class];
    NSString *desc = [cl description];
    if ([name isEqualToString:desc])
        return aView;
    for (UIView *view in aView.subviews) {
        Class cll = [view class];
        NSString *stringl = [cll description];
        if ([stringl isEqualToString:name]) {
            return view;
        }
    }    
    return nil;
}
 
-(void)addSomeElements:(UIViewController *)viewController{
    UIView *PLCameraView = [self findView:viewController.view withName:@"PLCameraView"];
    UIView *PLCropOverlay = [self findView:PLCameraView withName:@"PLCropOverlay"];
    UIView *bottomBar = [self findView:PLCropOverlay withName:@"PLCropOverlayBottomBar"];
    UIImageView *bottomBarImageForSave = [bottomBar.subviews objectAtIndex:0];
    UIButton *retakeButton=[bottomBarImageForSave.subviews objectAtIndex:0];
    [retakeButton setTitle:@"重拍"  forState:UIControlStateNormal];
    UIButton *useButton=[bottomBarImageForSave.subviews objectAtIndex:1];
    [useButton setTitle:@"保存" forState:UIControlStateNormal];
    UIImageView *bottomBarImageForCamera = [bottomBar.subviews objectAtIndex:1];
    UIButton *cancelButton=[bottomBarImageForCamera.subviews objectAtIndex:1];
    [cancelButton setTitle:@"取消" forState:UIControlStateNormal];
}
 
- (void)navigationController:(UINavigationController *)navigationController willShowViewController:(UIViewController *)viewController animated:(BOOL)animated
{
    [self addSomeElements:viewController];
}
