我在调用此自定义刷新时遇到无法关闭 CDVViewController 的问题，它会在后台保持加载并加载一个新的导致内存泄漏/高内存使用的新的。我尝试对 webView、子视图、CDVViewController、ChildViewController 使用 release 和 removeFromSuperview，但它们都不起作用。我正在通过 Storyboard 运行选项卡栏控制器，（我必须调用 CDVViewController 作为子视图的另一个原因）当我通过 safari 使用网络检查器时，我可以看到在该选项卡上建立的页面，当我在另一个选项卡上刷新时（不使用 CDVViewController/phonegap）它工作正常。任何帮助深表感谢。
所以这是我的 .h
#import <UIKit/UIKit.h>
#import <ifaddrs.h>
#import <arpa/inet.h>
#import <Cordova/CDVViewController.h>
@interface ThirdViewController : CDVViewController <UIWebViewDelegate>
{
IBOutlet CDVViewController *webView;
IBOutlet UIActivityIndicatorView *activityind;
}
- (IBAction)Refresh:(id)sender;
@end
还有我的.m
@interface ThirdViewController ()
@end
@implementation ThirdViewController
- (void)viewDidLoad
{
webView = [CDVViewController new];
webView.startPage = @"MYWEBSITE";
[self addChildViewController:webView];
[self.webView addSubview:webView.view];
webView.view.frame = CGRectMake(0, 0, 0, 0);
[activityind startAnimating];
[self.webView addSubview: activityind];
[self CustomActivity];
}
-(void) CustomActivity
{
if ([webView.reference isEqualToString:@"TRUE"]){ //webView.reference is something I added into phonegap CDVViewController so that I am able to see when it is being loaded/used to load the custom activity/activity ind to work.
[activityind removeFromSuperview];
}else{
[NSTimer scheduledTimerWithTimeInterval:.5 target:self selector:@selector(CustomActivity) userInfo:nil repeats:NO];
}
}
- (IBAction)Refresh:(id)sender {
webView = [CDVViewController new];
webView.startPage = @"MYWEBSITE";
[self addChildViewController:webView];
[self.webView addSubview:webView.view];
webView.view.frame = CGRectMake (0,0,self.view.frame.size.width,(self.view.frame.size.height -44));
[activityind startAnimating];
[self.webView addSubview: activityind];
[self CustomActivity];
}
- (void)webViewDidStartLoad:(UIWebView *)webView {}
- (void)webViewDidFinishLoad:(UIWebView *)subview {}
- (void)loading {}
- (void)didReceiveMemoryWarning{[super didReceiveMemoryWarning];}
