下面的是其中背景图片的素材。

使用的时候在你想调用的地方：

UIView*waitView=[WaitViewCreateWaitView:@"正在努力加载....." tag:100];

 [self.view addSubview:waitView];

不要忘记导入 ：  

#import "WaitView.h"

//****************************************************和上面无关。

- (void)showWaitView:(NSString*)info;

- (void)dismissWaitView;

- (void)showWaitView:(NSString*)info

{

    UIView *waitView = [WaitViewCreateWaitView:info tag:(EFAMILYNUMTAG*2)];

    [self.view addSubview:waitView];

    self.view.userInteractionEnabled =NO;

}

- (void)dismissWaitView

{

    [[self.viewviewWithTag:(EFAMILYNUMTAG*2)]removeFromSuperview];

    self.view.userInteractionEnabled =YES;

}
