　　有一段时间没有更新博客了，今天更新一篇关于最近工作中用到的一个功能，先简单描述一下：我们知道，测试人员在测试客户端产品时，当出现问题或者BUG的时候，都得先对页面截图，然后从相册中选择截图，加上一段描述放到TD库或者直接通过邮件发给开发人员，以方便开发人员进行修改，过程繁琐。通过下面功能的介绍，您可以很方便的让测试人员遇到BUG的时候，摇一摇设备，然后自动截图并保存到应用的沙盒之中。截图保存到沙盒之后，您可以自定义一个问题反馈的页面，对问题进行描述(描述可使用第三方平台，如讯飞语音，实现语音录入的效果)之后，将描述信息和页面截图一起发送给开发人员(可以是邮件，也可以是直接发送到后台)。

　　下面来看看功能是怎么实现的。

　　首先，定义了一个category：ShakeAndCutter

　　UIViewController+ShakeAndCutter.h文件源码：

#import <UIKit/UIKit.h>@interface UIViewController (ShakeAndCutter)@end

　　UIViewController+ShakeAndCutter.m文件源码：

 1 #import "UIViewController+ShakeAndCutter.h" 2 #import <QuartzCore/QuartzCore.h> 3 #import "TestFeedbackViewController.h" 4  5 @implementation UIViewController (ShakeAndCutter) 6  7 - (BOOL)canBecomeFirstResponder 8 { 9     return YES;10 }11 12 #PRagma mark - 摇一摇动作处理13 14 - (void)motionBegan:(UIEventSubtype)motion withEvent:(UIEvent *)event15 {16     NSLog(@"began");17 }18 19 - (void)motionCancelled:(UIEventSubtype)motion withEvent:(UIEvent *)event20 {21     NSLog(@"cancel");22 }23 24 - (void)motionEnded:(UIEventSubtype)motion withEvent:(UIEvent *)event25 {26     NSLog(@"end");27     [self cutterViewToDocument];28     29     // 这里是自定义的问题反馈页面,也可以直接跳转到系统邮件发送的页面30     TestFeedbackViewController *testFeedbackViewController = [[[TestFeedbackViewController alloc] initWithNibName:@"TestFeedbackViewController" bundle:nil] autorelease];31     [self.navigationController pushViewController:testFeedbackViewController animated:YES];32 }33 34 #pragma mark - 截屏处理35 36 - (void)cutterViewToDocument37 {38     UIWindow *screenWindow = [[UIapplication sharedApplication] keyWindow];39     40     UIGraphicsBeginImageContext(screenWindow.frame.size);41     [screenWindow.layer renderInContext:UIGraphicsGetCurrentContext()];42     UIImage *screenShot = UIGraphicsGetImageFromCurrentImageContext();43     UIGraphicsEndImageContext();44     45     NSData *screenShotPNG = UIImagePNGRepresentation(screenShot);46     NSError *error = nil;47     [screenShotPNG writeToFile:[[NSHomeDirectory() stringByAppendingPathComponent:@"Documents"] stringByAppendingPathComponent:@"error.png"] options:NSAtomicWrite error:&error];48 }49 50 @end

　　至此，摇一摇和截图功能就已经完成了，那么在应用中怎么使用呢？

对于IOS6.0以上的设备，只需要在项目的pch文件中引进头文件#import "UIViewController+ShakeAndCutter.h"即可(我在IOS6.0.1、IOS6.1.5、IOS7.0.6设备上已经测试过)，这样测试工作完成之后，您只需要将这行代码注释或者删除就可以了；
对于IOS6.0以下的设备，在需要实现摇一摇效果的页面，有可能要加入如下代码(手头没有IOS6.0以下的设备，如果大家有的话，帮忙验证一下，非常感谢)：

　　1.viewDidLoad方法中，添加两行代码：

1 [[UIApplication sharedApplication] setApplicationSupportsShakeToEdit:YES];2 [self becomeFirstResponder];

2.viewDidAppear方法中，添加一行代码：

1 [self becomeFirstResponder];

3.viewDidDisappear方法中，添加一行代码：

1 [self resignFirstResponder];

　　当然，以上的功能，您也可以实现其他的效果：比如说用户问题的反馈等等，具体可以根据应用的需求而定。

　　这里，再附上发送到邮件功能的示例代码：

　　MailViewController.h文件源码：

 1 #import <UIKit/UIKit.h> 2 #import <MessageUI/MessageUI.h> 3 #import<MessageUI/MFMailComposeViewController.h> 4  5 @interface MailViewController : UIViewController<MFMailComposeViewControllerDelegate, 6 MFMessageComposeViewControllerDelegate> 7 { 8     UIButton                    *shareToMailButton; 9 }10 11 @end

　　MailViewController.m文件源码：

  1 #import "MailViewController.h"  2 #import "Constants.h"  3   4 @interface MailViewController ()  5   6 @end  7   8 @implementation MailViewController  9  10 - (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil 11 { 12     self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil];

25      26     shareToMailButton = [self buttonWithFrame:CGRectMake(20, 100, 280, 40) action:@selector(btnClicked:) withTag:1000]; 27     [shareToMailButton setTitle:@"Bug反馈" forState:UIControlStateNormal]; 28 } 29  30 - (void)didReceiveMemoryWarning 31 { 32     [super didReceiveMemoryWarning]; 33     // Dispose of any resources that can be recreated. 34 } 35  36 #pragma mark - 自定义方法 37  38 - (void)btnClicked:(id)sender 39 { 40     UIButton *btnSender = (UIButton *)sender;
