iOS flutter 混编 tabBar 隐藏flutter 界面出现黑边
记录 问题
问题描述，
在UITabBarController 中加一个 flutter 界面，
flutter 界面跳转到二级页面，隐藏tabbar
tabbar 位置出现黑色底边，flutter 页面不能全屏。
解决方法 ：
自己的 controller 继承 FlutterViewController
重写viewDidAppear方法
找到self.view 上的子控件，重设frame
- (void)viewDidAppear:(BOOL)animated{
[super viewDidAppear:animated];
self.tabBarController.tabBar.hidden = NO;
NSArray *views = self.view.subviews;
UIScrollView *scrollerView;
for (UIView *view in views) {
if ([view isKindOfClass:[UIScrollView class]]) {
scrollerView = (UIScrollView *)view;
}
}
self.view.frame = CGRectMake(0, 0, SCREEN_WIDTH, SCREEN_HEIGHT);
scrollerView.frame = CGRectMake(0, 0, SCREEN_WIDTH, SCREEN_HEIGHT);
}
相关代码：
- (instancetype)init
{
self = [super init];
if (self) {
[self setInitialRoute:@"home"];
NSString *channelName = @"zhe li sui yi xie";
FlutterMethodChannel *methodChannel = [FlutterMethodChannel methodChannelWithName:channelName binaryMessenger:[self binaryMessenger]];
NSString *eventName = @"zhe li sui yi xie";
self.eventChannel = [FlutterEventChannel eventChannelWithName:eventName binaryMessenger:[self binaryMessenger]];
[self.eventChannel setStreamHandler:self];
[methodChannel setMethodCallHandler:^(FlutterMethodCall * _Nonnull call, FlutterResult _Nonnull result) {
NSLog(@"method=%@ \narguments = %@", call.method, call.arguments);
if ([call.method isEqualToString:@"scan"]) {
NSLog(@"扫码");
}
if ([call.method isEqualToString:@"config"]) {
NSDictionary *dic = @{@"baseURL":CommonURL,@"token":[kUserDefaults objectForKey:UserToken],@"themeType":@NO};
result(dic);
}
if ([call.method isEqualToString:@"setToolBar"]) {
BOOL hidden = call.arguments;
if ([call.arguments isEqual:@"true"]) {
hidden = YES;
}else{
hidden = NO;
}
self.tabBarController.tabBar.hidden = hidden;
result(@YES);
}
if ([call.method isEqualToString:@"logout"]) {
NSLog(@"退出登录");
}
}];
}
return self;
}
