說明跳轉到的控制器主線程負荷太大了,所以解決方法以下:spa
OtherCardViewController *card = [self.storyboard instantiateViewControllerWithIdentifier:@"OtherCard"];線程
card.data=data;orm
__block id copyself=self;get
dispatch_async(dispatch_get_main_queue(), ^{it
[copyself presentViewController:cardio
animated:YESqueue
completion:nil];方法
});
