iOS 异常处理，将bug信息发送到开发者邮箱

标签：ios   异常   try   xcode   select   

1.iOS

在程序的开发中我们难免会遇到崩溃的问题。然后在用户体验的时候，我们如何来防止崩溃的发生呢，并将我们的崩溃原因发送给开发者来处理它。

来看一个例子

NSString *str = @"523";
        arr = @[@"sdad", @"dwada", @"ffwwra"];
        [str substringFromIndex:111];

    @try {
        NSString *str = @"523";
        arr = @[@"sdad", @"dwada", @"ffwwra"];
        [str substringFromIndex:111];
    }
    @catch (NSException *exception) {
        NSLog(@"%s %@", __FUNCTION__, exception);
    }
    @finally {
        //如何来对待这个异常处理
        NSLog(@"tryTwo - 我一定会执行");
    }

怎么样来实现发送给开发者邮件呢？

在iOS中发送邮件是很简单的。

封装来如下方法
