IOS in Shake achieve screenshots (question feedback function can be realized)

　　There was a time not update the blog update today an article on a recent function used in the work, briefly describe: We know that the testers in the test client product, when there is a problem or BUG, had first screenshot of the page, then select an album from the screenshot, add a description into the TD library or directly by e-mail to the developer, in order to facilitate the development of personnel changes, process cumbersome . By introducing the following features, you can easily let the testers when it came to the BUG, shake the device, then automatically capture and save the sandbox application in. After saving the screenshot after the sandbox, you can customize the feedback page of a problem, describe the issue (Description You can use a third-party platforms such as hearing fly voice, to achieve the effect of voice recording), will be sent with the information and description page screenshot to developers (can be e-mail, it can also be sent directly to the background).

　　Let's look at how the function is implemented.

　　First, define a category: ShakeAndCutter

　　UIViewController + ShakeAndCutter.h file Source:

#import <UIKit/UIKit.h>

@interface UIViewController (ShakeAndCutter)

@end

　　UIViewController + ShakeAndCutter.m file Source:

 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 *)event
15 {
16     NSLog(@"began");
17 }
18 
19 - (void)motionCancelled:(UIEventSubtype)motion withEvent:(UIEvent *)event
20 {
21     NSLog(@"cancel");
22 }
23 
24 - (void)motionEnded:(UIEventSubtype)motion withEvent:(UIEvent *)event
25 {
26     NSLog(@"end");
27     [self cutterViewToDocument];
28     
29     //This is the feedback from the problem definition page, or go directly to the page message sent by the system 
30      TestFeedbackViewController testFeedbackViewController * = [[[TestFeedbackViewController the alloc] initWithNibName: @ " TestFeedbackViewController " the bundle: nil] the autorelease];
 31 is      [self.navigationController pushViewController : Animated testFeedbackViewController: YES];
 32  }
 33 is  
34 is  #pragma Mark - processing screenshots
 35  
36 - ( void ) cutterViewToDocument
 37 [  {
 38 is      the UIWindow screenWindow * = [[sharedApplication the UIApplication] 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

　　At this point, shake and screenshot function has been completed, then how to use it in the application?

• For IOS6.0 above devices, only you need to project pch introduction header file #import "UIViewController + ShakeAndCutter.h" can ( I IOS6.0.1 , IOS6.1.5 , IOS7.0.6 has been tested on the device ) , after the completion of this test, you only need this line of code or comments can be deleted;
• For IOS6.0 following equipment, the page needs to implement a shake effect, it is possible to add the following code (do not have IOS6.0 following equipment, if any, everyone, to help verify it, thank you very much):

　　1.viewDidLoad method, add two lines of code:

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

        2.viewDidAppear method, add a line:

1 [self becomeFirstResponder];

        3.viewDidDisappear method, add a line:

1 [self resignFirstResponder];

　　Of course, the above features, you can also achieve other effects: for example, the issue of user feedback, etc., can be based on specific application requirements.

　　

　　Here, the sample code then attach message sent to the function:
