IOS隐藏键盘-白红宇

最近遇到二个键盘会自动弹出的问题：

1、UIWebView加载网页后，点击网页内的链接在UIWebView内进行跳转时，键盘自动弹起；

2、调用选择照片时，iPod上选择照片后也会自动弹出键盘，比如从图库进到具体某个文件夹内，或者再返回图库，直接点中照片然后编辑的时候，都会自动弹出；

问题一是这样处理的

- (void)webViewDidStartLoad:(UIWebView*)webView {
       [activityIndicatorView_ startAnimating];         // update by zhangyi     [[[UIApplication sharedApplication] keyWindow] endEditing:YES];     [[UIApplication sharedApplication] sendAction:@selector(resignFirstResponder) to:nil from:nil forEvent:nil]; } - (void)webViewDidFinishLoad:(UIWebView*)webView {
       [activityIndicatorView_ stopAnimating];         [[[UIApplication sharedApplication] keyWindow] endEditing:YES];     [[UIApplication sharedApplication] sendAction:@selector(resignFirstResponder) to:nil from:nil forEvent:nil]; } - (void)webView:(UIWebView*)webView didFailLoadWithError:(NSError*)error {
       [activityIndicatorView_ stopAnimating];         UIAlertView *alterview = [[UIAlertView alloc] initWithTitle:@"" message:[error localizedDescription]  delegate:nil cancelButtonTitle:nil otherButtonTitles:@"OK", nil];     [alterview show];     [alterview release]; }

网页开始加载或加载结束时关闭键盘并发送关闭键盘的事件，如果webViewDidFinishLoad()不被调用是因为uiwebview对象需要设置delegate为self。UIWebView的透明设置，只需要增加二个属性

webView_.opaque = NO; webView_.backgroundColor = [UIColor clearColor];

第二个问题的处理方案是，在导航切换的时候隐藏键盘并发送关闭键盘的事件

-(void)navigationController:(UINavigationController *)navigationController willShowViewController:(UIViewController *)viewController animated:(BOOL)animated {
       viewController.contentSizeForViewInPopover = navigationController.topViewController.view.frame.size;     [self HiddenStatusBarForIOS7];         // update by zhangyi     [[[UIApplication sharedApplication] keyWindow] endEditing:YES]; }   // update by zhangyi -(void)navigationController:(UINavigationController *)navigationController didShowViewController:(UIViewController *)viewController animated:(BOOL)animated {
       [[[UIApplication sharedApplication] keyWindow] endEditing:YES];        [[UIApplication sharedApplication] sendAction:@selector(resignFirstResponder) to:nil from:nil forEvent:nil]; }

因为接触ios也不算特别多，暂时就使用了上述的方法来处理了。
