邮件发送异常信息

在- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions方法中加上以下一句代码：

 

NSSetUncaughtExceptionHandler(&UncaughtExceptionHandler);

 

UncaughtExceptionHandler(NSException *exception)的实现如下：

 

void UncaughtExceptionHandler(NSException *exception) {
	NSArray *arr = [exception callStackSymbols];
	NSString *reason = [exception reason];
	NSString *name = [exception name];
	
	NSString *urlStr = [NSString stringWithFormat:@"mailto://[e-mail]?subject=bug报告&body=感谢您的配合!<br><br><br>错误详情:<br>%@<br><br>%@<br><br>%@", 
						name, reason, [arr componentsJoinedByString:@"<br>"]];
	
	NSURL *url = [NSURL URLWithString:[urlStr stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding]];
    
	[[UIApplication sharedApplication] openURL:url];
}

 

这样，当程序发生异常的时候，会自动打开邮件发送页面。
