【问题描述】:
我目前在 react native 上使用 imagepicker。当我使用 android 来选择图像时,它工作正常。但是,当我使用 iOS 时,当我选择照片时它会崩溃。
这是它在 xcode 调试器中显示的错误:
2020-04-03 11:54:27.802434+0800 app[7218:1993193] -[NSURLResponse allHeaderFields]:无法识别的选择器发送到实例 0x28281aba0 2020-04-03 11:54:27.802766+0800 app[7218:1993193] * 由于未捕获的异常“NSInvalidArgumentException”而终止应用程序,原因:“-[NSURLResponse allHeaderFields]:无法识别的选择器发送到实例 0x28281aba0” * 首先抛出调用栈: (0x19d01c164 0x19cd30c1c 0x19cf1a7e0 0x19d02085c 0x102b27bc8 0x102b27a90 0x102b27a90 0x102b01ce0 0x1059f5d10 0x1059f718c 0x1059ff718c 0x1059ff580 0x1059ff580 0x1059ff580 0x105a0b0f0 0x19cd23714 0x19cd299c8) libc++abi.dylib:以 NSException 类型的未捕获异常终止
这是我的代码:
chooseImage = async (id) => {
//await this.askPermissionsAsync();
let options = {
title: 'Select Image',
storageOptions: {
skipBackup: true,
path: 'images',
},
};
ImagePicker.showImagePicker(options, (response) => {
console.log('Response = ', response.error);
if (response.didCancel) {
console.log('User cancelled image picker');
} else if (response.error) {
console.log('ImagePicker Error: ', response.error);
} else {
const source = { uri: response.uri };
// You can also display the image using data:
// const source = { uri: 'data:image/jpeg;base64,' + response.data };
// alert(JSON.stringify(response));
let file_data = [...this.state.fileData];
file_data[id] = response.data;
let file_uri = [...this.state.fileUri];
file_uri[id] = response.uri;
this.setState({filePath:response, fileData: file_data, fileUri: file_uri});
}
});
}
我还在 info.plist 中添加了权限:
<key>NSCameraUsageDescription</key>
<string></string>
<key>NSPhotoLibraryUsageDescription</key>
<string></string>
<key>NSPhotoLibraryAddUsageDescription</key>
<string></string>
<key>NSDocumentsFolderUsageDescription</key>
<string></string>
但问题仍然存在于 ios。
