封装Plugin组件注意事项
iOS组件可能要用到appdelegate中的相关的回调方法。此时针对具有bool返回值会有的回调方法会有问题:
- 如果返回
YES ,则先调用的组件会导致后调用的组件相同的回调方法无法执行
- 如果返回
NO,在冷启动的时候,回调方法不会被吊起。
处理方法
可以通过统一返回FlutterPluginAppLifeCycleDelegate调用方法来处理
1.声明FlutterPluginAppLifeCycleDelegate

| @interface YochatsharePlugin()
@property FlutterMethodChannel *methodChannel;
@property (nonatomic, strong) NSMutableDictionary *shareDataSource;
@property (nonatomic, strong) FlutterPluginAppLifeCycleDelegate* lifeCycleDelegate;
@end
|
2.初始化FlutterPluginAppLifeCycleDelegate

| - (instancetype)init {
if (self = [super init]) {
_lifeCycleDelegate = [[FlutterPluginAppLifeCycleDelegate alloc] init];
}
return self;
}

3.通过FlutterPluginAppLifeCycleDelegate返回

[MCShareConfig shareInstance].groupId = @"group.com.atomcloudstudio.splashchat";
[MCShareConfig shareInstance].containAppScheme = @"yochatshare://";
__weak typeof(self) weakSelf = self;
if (self.shareDataSource.count == 0) return YES;
[self.shareDataSource removeAllObjects];
[self.methodChannel invokeMethod:@"sendPhoto" arguments:self.shareDataSource result:^(id _Nullable result) {
[weakSelf.shareDataSource removeAllObjects];
[MCShareTool mcs_clearData];
}];
return [_lifeCycleDelegate application:application didFinishLaunchingWithOptions:launchOptions];
}
