关于uiimagepicker拍照与录像按钮是否显示问题

导入

#import <MobileCoreServices/UTCoreTypes.h>

如果只想拍照，设置

iPicker.mediaTypes = [[NSArray alloc] initWithObjects: (NSString *) kUTTypeImage, nil];

如果只想录像，设置

iPicker.mediaTypes = [[NSArray alloc] initWithObjects: (NSString *) kUTTypeMovie, nil];

默认都显示的，设置

iPicker.mediaTypes = [UIImagePickerController availableMediaTypesForSourceType: UIImagePickerControllerSourceTypeCamera];
