ios 获取 crash 日志

#import <Foundation/Foundation.h>

@interface CatchCrash :
NSObject
void uncaughtExceptionHandler(NSException *exception);
@end

#import "CatchCrash.h"

@implementation CatchCrash
void uncaughtExceptionHandler(NSException *exception)

{
    
    // 异常的堆栈信息
    
    NSArray *stackArray = [exception
callStackSymbols];
    
    // 出现异常的原因
    
    NSString *reason = [exception
reason];
    // 异常名称
    
    NSString *name = [exception
name];
    
    NSString *exceptionInfo = [NSString
stringWithFormat:@"Exception reason：%@\nException name：%@\nException stack：%@",name,
reason, stackArray];
    
    NSLog(@"crashLog------------%@-------------crashLog", exceptionInfo);

还可以 发送日志我自己哦
//    NSString *syserror = [NSString stringWithFormat:@"mailto://595814260@qq.com?subject=bug报告&body=感谢您的配合!<br><br><br>"
//                          "Error Detail:<br>%@<br>--------------------------<br>%@<br>---------------------<br>%@",
//                          name,reason,[stackArray componentsJoinedByString:@"<br>"]];
//    
////    NSMutableArray *tmpArr = [NSMutableArray arrayWithArray:stackArray];
////    
////    [tmpArr insertObject:reason atIndex:0];
//    NSURL *url = [NSURL URLWithString:[syserror stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding]];
//    [[UIApplication sharedApplication] openURL:url];
    //保存到本地  -- 
当然你可以在下次启动的时候，上传这个log
    
    //[exceptionInfo writeToFile:[NSString stringWithFormat:@"%@/Documents/error.log",NSHomeDirectory()]  atomically:YES encoding:NSUTF8StringEncoding error:nil];
