重要
PhotoPicker 组件已被完全重构。
如果您正在使用旧遗留代码，可以在 pp-v1-legacy 分支中找到。阅读文档并迁移到新的 Photo Picker 版本。它包含库和示例项目，您可以用作参考。
原生 Android 组件
Android 组件已被移动到其自身的独立 GitHub 仓库。
您可以在以下链接找到它以及示例项目： https://github.com/chute/photo-picker-plus-android
PhotoPickerPlus
除了 Chute SDK（您也可以在这里找到它）之外的任何外部依赖项
https://github.com/chute/Chute-SDK-v2-iOS
描述
此类允许您从任何受支持的在线源（例如 Facebook、Instagram 和 Dropbox 等）中选择照片或视频。它还替换了标准选择器，因为它允许您从设备中选择照片和视频，使用相机拍照或录制视频，或者仅选择您的库中的最新照片/视频。它支持多图选择，就像苹果的原生 Image Picker。

配置
首先，您需要设置配置。按照Photo Picker 配置的说明，使用合适的配置初始化 PhotoPicker+ 组件。
初始化
- isMultipleSelectionEnabled -
BOOL- 如果是 YES，选择器进行多图选择，如果是 NO，选择器进行单图选择。 - delegate
NSObject <PhotoPickerPlusDelegate>- 此组件的代理。它应根据单图还是多图选择实现以下两个代理方法之一。-
- (void)imagePickerController:(PhotoPickerViewController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info; -
- (void)imagePickerController:(PhotoPickerViewController *)picker didFinishPickingArrayOfMediaWithInfo:(NSArray *)info; -
- (void)imagePickerControllerDidCancel:(PhotoPickerViewController *)picker;
-
实现
您需要将 PhotoPickerViewController.h 实现在您的 .h 文件中。您还需要添加 <PhotoPickerViewControllerDelegate>
- (void)imagePickerControllerDidCancel:(PhotoPickerViewController *)picker{
if (self.popoverController) {
[self.popoverController dismissPopoverAnimated:YES];
}
else {
[self dismissViewControllerAnimated:YES completion:nil];
}
}
///////////////////////////
// Single Selection //
///////////////////////////
- (void)showPhotoPickerPlus {
PhotoPickerViewController *picker = [PhotoPickerViewController new];
[picker setDelegate:self];
[picker setIsMultipleSelectionEnabled:NO];
if (UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPad) {
if (![[self popoverController] isPopoverVisible]) {
UIPopoverController *popover = [[UIPopoverController alloc] initWithContentViewController:picker];
[popover presentPopoverFromRect:[sender frame] inView:self.view permittedArrowDirections:UIPopoverArrowDirectionAny animated:YES];
self.popoverController = popover;
}
else {
[[self popoverController] dismissPopoverAnimated:YES];
}
}
else {
[self presentViewController:picker animated:YES completion:nil];
}
}
- (void)imagePickerController:(PhotoPickerViewController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info{
//place code for when the user picks photos here and do any
//additional work such as removing the picker from the screen
}
///////////////////////////
// Multi Selection //
///////////////////////////
- (void)showPhotoPickerPlus {
PhotoPickerViewController *picker = [PhotoPickerViewController new];
[picker setDelegate:self];
[picker setIsMultipleSelectionEnabled:YES];
if (UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPad) {
if (![[self popoverController] isPopoverVisible]) {
UIPopoverController *popover = [[UIPopoverController alloc] initWithContentViewController:picker];
[popover presentPopoverFromRect:[sender frame] inView:self.view permittedArrowDirections:UIPopoverArrowDirectionAny animated:YES];
self.popoverController = popover;
}
else {
[[self popoverController] dismissPopoverAnimated:YES];
}
}
else {
[self presentViewController:picker animated:YES completion:nil];
}
}
- (void)imagePickerController:(PhotoPickerViewController *)picker didFinishPickingArrayOfMediaWithInfo:(NSArray *)info{
//place code for when the user picks photos here and do any
//additional work such as removing the picker from the screen
}
