iOS应用中网络等待Loading的实现方法

概述iOS应用中网络等待Loading的实现方法

下面是内存溢出 jb51.cc 通过网络收集整理的代码片段。

内存溢出小编现在分享给大家，也给大家做个参考。

//创建UIWebVIEwWebVIEw = [[UIWebVIEw alloc] initWithFrame:CGRectMake(0,44,320,400)];[WebVIEw setUserInteractionEnabled:NO];[WebVIEw setBackgroundcolor:[UIcolor clearcolor]];[WebVIEw setDelegate:self];[WebVIEw setopaque:NO];//使网页透明Nsstring *path = @"http://www.baIDu.com";NSURL *url = [NSURL URLWithString:path];[WebVIEw loadRequest:[NSURLRequest requestWithURL:url]];//创建UIActivityIndicatorVIEw背底半透明VIEw    UIVIEw *vIEw = [[UIVIEw alloc] initWithFrame:CGRectMake(0,480)];[vIEw setTag:103];[vIEw setBackgroundcolor:[UIcolor blackcolor]];[vIEw setAlpha:0.8];[self.vIEw addSubvIEw:vIEw];activityIndicator = [[UIActivityIndicatorVIEw alloc] initWithFrame:CGRectMake(0.0f,0.0f,32.0f,32.0f)];[activityIndicator setCenter:vIEw.center];[activityIndicator setActivityIndicatorVIEwStyle:UIActivityIndicatorVIEwStyleWhite];[vIEw addSubvIEw:activityIndicator];[self.vIEw addSubvIEw:WebVIEw];[vIEw release];[WebVIEw release];//开始加载数据- (voID)webVIEwDIDStartLoad:(UIWebVIEw *)webVIEw {          [activityIndicator startAnimating];         }//数据加载完- (voID)webVIEwDIDFinishLoad:(UIWebVIEw *)webVIEw {     [activityIndicator stopAnimating];         UIVIEw *vIEw = (UIVIEw *)[self.vIEw vIEwWithTag:103];     [vIEw removeFromSupervIEw];}

  第二种方法：使用UIAlertVIEw and UIActivityIndicatorVIEw

/加载网页动画- (voID)webVIEwDIDStartLoad:(UIWebVIEw *)webVIEw{    if (myAlert==nil){               myAlert = [[UIAlertVIEw alloc] initWithTitle:nil                                                               message: @"读取中..."                                                                delegate: self                                                 cancelbuttonTitle: nil                                                 otherbuttonTitles: nil];     UIActivityIndicatorVIEw *activityVIEw = [[UIActivityIndicatorVIEw alloc] initWithActivityIndicatorStyle:UIActivityIndicatorVIEwStyleWhite];     activityVIEw.frame = CGRectMake(120.f,48.0f,38.0f,38.0f);     [myAlert addSubvIEw:activityVIEw];     [activityVIEw startAnimating];     [myAlert show];     }}- (voID)webVIEwDIDFinishLoad:(UIWebVIEw *)webVIEw{       [myAlert dismissWithClickedbuttonIndex:0 animated:YES];}
