iOS catches exceptions and sends pictures for easy resolution of bugs

In the development process, we sometimes leave a bug, users in the use of our app, sometimes there will be a flashback, this time we can let users send us email, so that our developers more high-speed status to the location of the bug. Solve the problem in the quickest time. Also improve the user experience at the same time.

in the APPDELEGATE.M file, add code such as the following:

01	NSUncaughtExceptionHandler* _uncaughtExceptionHandler = nil;

02	voidUncaughtExceptionHandler(NSException *exception) {

03	NSLog(@"CRASH: %@", exception);

04	NSLog(@"Stack Trace: %@", [exception callStackSymbols]);

05

06	// 异常的堆栈信息

07	NSArray *stackArray = [exception callStackSymbols];

08	// 出现异常的原因

09	NSString *reason = [exception reason];

10

// 异常名称

11	NSString *name = [exception name];

12

13	NSString *syserror = [NSString stringWithFormat:@"mailto://[email protected]?subject=bug报告&body=感谢您的配合!<br><br><br>"

14	"Error Detail:<br>%@<br>--------------------------<br>%@<br>---------------------<br>%@",

15	name,reason,[stackArray componentsJoinedByString:@"<br>"]];

16

17	NSURL *url = [NSURL URLWithString:[syserror stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding]];

18	[[UIApplication sharedApplication] openURL:url];

19

return;

20

}

And then in- ( BOOL ) Application: ( uiapplication *) Application didfinishlaunchingwithoptions: (nsdictionary *) Add code to the Launchoptions method:

1	// 保存系统处理异常的Handler

2	_uncaughtExceptionHandler = NSGetUncaughtExceptionHandler();

3

4	// 设置处理异常的Handler

5	NSSetUncaughtExceptionHandler(&UncaughtExceptionHandler);
