iOS 崩溃日志

#import <Foundation/Foundation.h>

@interface ZRUncaughtExceptionHandler : NSObject

+ (void)setDefaultHandler;
+ (NSUncaughtExceptionHandler*)getHandler;

@end

#import "ZRUncaughtExceptionHandler.h"

@implementation ZRUncaughtExceptionHandler

NSString *applicationDocumentsDirectory() {
    return [NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES) lastObject];
}

void UncaughtExceptionHandler(NSException *exception) {
    NSArray *arr = [exception callStackSymbols];
    NSString *reason = [exception reason];
    NSString *name = [exception name];
    
    NSString *url = [NSString stringWithFormat:@"=============异常崩溃报告=============\nname:\n%@\nreason:\n%@\ncallStackSymbols:\n%@",
                     name,reason,[arr componentsJoinedByString:@"\n"]];
    NSString *path = [applicationDocumentsDirectory() stringByAppendingPathComponent:@"Exception.txt"];
    [url writeToFile:path atomically:YES encoding:NSUTF8StringEncoding error:nil];
}

- (NSString *)applicationDocumentsDirectory {
    return [NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES) lastObject];
}

+ (void)setDefaultHandler
{
    NSSetUncaughtExceptionHandler (&UncaughtExceptionHandler);
}

+ (NSUncaughtExceptionHandler*)getHandler
{
    return NSGetUncaughtExceptionHandler();
}

@end

使用如下

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
    
    [ZRUncaughtExceptionHandler setDefaultHandler];
    
    return YES;
}
