*抓取日志并解析

1. 改为.crash后缀
   2.选择 view device logs;

8DE18528-DD81-41DD-825D-95DF0F9A12AA.png

3.把内容清空以后把.crash文件推进去

B4860B38-CCEA-4034-BFF8-CCA40FC4E5AC.png

4.找到last Exception Backtrace 看看崩在哪了

添加阴影shadowPath

添加QuartzCore框架到项目中（如果不存在的话）
导入QuartzCore到您的执行文件
[_backGroundView.layer setShadowOpacity:1];
[_backGroundView.layer setShadowPath:[[UIBezierPath bezierPathWithRect:_backGroundView.bounds] CGPath]];

优化

优化Table View

Table view需要有很好的滚动性能，不然用户会在滚动过程中发现动画的瑕疵。

为了保证table view平滑滚动，确保你采取了以下的措施:

· 正确使用reuseIdentifier来重用cells

· 尽量使所有的view opaque，包括cell自身

· 避免渐变，图片缩放，后台选人

· 缓存行高

· 如果cell内现实的内容来自web，使用异步加载，缓存请求结果

· 使用shadowPath来画阴影

· 减少subviews的数量

· 尽量不适用cellForRowAtIndexPath:，如果你需要用到它，只用一次然后缓存结果

· 使用正确的数据结构来存储数据

· 使用rowHeight, sectionFooterHeight和 sectionHeaderHeight来设定固定的高，不要请求delegate

在Model中找ViewContoller

UIStoryboard *storyboard = [UIStoryboard storyboardWithName:@"Main" bundle:[NSBundle mainBundle]];
PublicDetailViewController *detailController = [storyboard instantiateViewControllerWithIdentifier:@"PublicDetailViewController"];
detailController.publicModel = publicModel;
[superController.navigationController pushViewController:detailController animated:YES];

打包发布时去掉所有的NSLog：NSLog打印比较耗费性能，特别是打印字符串的拼接，解决方法可以在pch文件中定义一个宏来替换NSLog，用自己定义的log函数，等到发布之前将自己的定义注释掉

当创建了大量的临时对象时，最好加入autorelesaepool保证对象及时的释放

-----------------Method swizzle 全局AOE-----------------

+ (void)load
{
static dispatch_once_t onceToken;
dispatch_once(&onceToken, ^{
    
    Class class = [self class];
    SEL originalSelector = @selector(init);
    SEL swizzledSelector = @selector(swizzleinit);
    Method swizzledMethod = class_getInstanceMethod(class, swizzledSelector);
    Method originalMethod = class_getInstanceMethod(class, originalSelector);
    class_addMethod(class,originalSelector,method_getImplementation(swizzledMethod),method_getTypeEncoding(swizzledMethod));
    class_replaceMethod(class, swizzledSelector, method_getImplementation(originalMethod), method_getTypeEncoding(originalMethod));

  //        [self exchangeSelector:@selector(init) withSelector:@selector(swizzleinit) class:self];
});
  }

GCD 代码 : http://git.oschina.net/fengyingjie/gcd/blob/master/FYJ_GCD/FYJ_GCD/ViewController.m?dir=0&filepath=FYJ_GCD%2FFYJ_GCD%2FViewController.m&oid=de9b56e3c1116dce34d9cbe61b02836acb7c4c0f&sha=dc57fd791361ae721a772f323eaa01ed282572fd

//异步执行 + 并行队列
- (void)asyncConcurrent{
//创建一个并行队列
dispatch_queue_t queue = dispatch_queue_create("标识符", DISPATCH_QUEUE_CONCURRENT);

    NSLog(@"---start---");

    //使用异步函数封装三个任务
    dispatch_async(queue, ^{
    NSLog(@"任务1---%@", [NSThread currentThread]);
    });
    dispatch_async(queue, ^{
    NSLog(@"任务2---%@", [NSThread currentThread]);
    });
dispatch_async(queue, ^{
    NSLog(@"任务3---%@", [NSThread currentThread]);
});

NSLog(@"---end---");
}

打印结果：
---start---
---end---
任务3---{number = 5, name = (null)}
任务2---{number = 4, name = (null)}
任务1---{number = 3, name = (null)}

//异步执行 + 串行队列
- (void)asyncSerial{
//创建一个串行队列
dispatch_queue_t queue = dispatch_queue_create("标识符", DISPATCH_QUEUE_SERIAL);

NSLog(@"---start---");
//使用异步函数封装三个任务
dispatch_async(queue, ^{
    NSLog(@"任务1---%@", [NSThread currentThread]);
});
dispatch_async(queue, ^{
    NSLog(@"任务2---%@", [NSThread currentThread]);
});
dispatch_async(queue, ^{
    NSLog(@"任务3---%@", [NSThread currentThread]);
});
NSLog(@"---end---");
}

打印结果：

---start---
---end---
任务1---{number = 3, name = (null)}
任务2---{number = 3, name = (null)}
任务3---{number = 3, name = (null)}

（三）同步执行 + 并行队列

实现代码：
//同步执行 + 并行队列
- (void)syncConcurrent{
//创建一个并行队列
dispatch_queue_t queue = dispatch_queue_create("标识符", DISPATCH_QUEUE_CONCURRENT);

NSLog(@"---start---");
//使用同步函数封装三个任务
dispatch_sync(queue, ^{
    NSLog(@"任务1---%@", [NSThread currentThread]);
});
dispatch_sync(queue, ^{
    NSLog(@"任务2---%@", [NSThread currentThread]);
});
dispatch_sync(queue, ^{
    NSLog(@"任务3---%@", [NSThread currentThread]);
});
NSLog(@"---end---");
  }

打印结果：
---start---
任务1---{number = 1, name = main}
任务2---{number = 1, name = main}
任务3---{number = 1, name = main}
---end---

（四）同步执行+ 串行队列

实现代码：
- (void)syncSerial{
//创建一个串行队列
dispatch_queue_t queue = dispatch_queue_create("标识符", DISPATCH_QUEUE_SERIAL);

NSLog(@"---start---");
//使用异步函数封装三个任务
dispatch_sync(queue, ^{
    NSLog(@"任务1---%@", [NSThread currentThread]);
});
dispatch_sync(queue, ^{
    NSLog(@"任务2---%@", [NSThread currentThread]);
});
dispatch_sync(queue, ^{
    NSLog(@"任务3---%@", [NSThread currentThread]);
});
NSLog(@"---end---");
}

打印结果：
---start---
任务1---{number = 1, name = main}
任务2---{number = 1, name = main}
任务3---{number = 1, name = main}
---end---

（五）异步执行+主队列

实现代码：
- (void)asyncMain{
//获取主队列
dispatch_queue_t queue = dispatch_get_main_queue();

NSLog(@"---start---");
//使用异步函数封装三个任务
dispatch_async(queue, ^{
    NSLog(@"任务1---%@", [NSThread currentThread]);
});
dispatch_async(queue, ^{
    NSLog(@"任务2---%@", [NSThread currentThread]);
});
dispatch_async(queue, ^{
    NSLog(@"任务3---%@", [NSThread currentThread]);
});
NSLog(@"---end---");
}

打印结果：
---start---
---end---
任务1---{number = 1, name = main}
任务2---{number = 1, name = main}
任务3---{number = 1, name = main}

（六）同步执行+主队列（死锁）

实现代码：
- (void)syncMain{
//获取主队列
dispatch_queue_t queue = dispatch_get_main_queue();

NSLog(@"---start---");
//使用同步函数封装三个任务
dispatch_sync(queue, ^{
    NSLog(@"任务1---%@", [NSThread currentThread]);
});
dispatch_sync(queue, ^{
    NSLog(@"任务2---%@", [NSThread currentThread]);
});
dispatch_sync(queue, ^{
    NSLog(@"任务3---%@", [NSThread currentThread]);
});
NSLog(@"---end---");
}

打印结果：
---start---
解释

主队列中的任务必须按顺序挨个执行

任务1要等主线程有空的时候（即主队列中的所有任务执行完）才能执行

主线程要执行完“打印end”的任务后才有空

“任务1”和“打印end”两个任务互相等待，造成死锁

跳转到TabBar的第几个界面

    self.tabBarController.selectedViewController = [self.tabBarController.viewControllers objectAtIndex:3];
    
 [self.navigationController popToRootViewControllerAnimated:YES];

自动生成模型
http://www.oschina.net/p/ESJsonFormat-Xcode?fromerr=dL1ZRfFR

生成公私匙

1. cd 到桌面
2. openssl
3. genrsa -out rsa_private_key.pem 1024
4. pkcs8 -topk8 -inform PEM -in rsa_private_key.pem -outform PEM –nocrypt
5. rsa -in rsa_private_key.pem -pubout -out rsa_public_key.pem

1、创建证书请求（按照提示输入信息）

openssl req -new -out cert.csr -key private_key.pem
2、自签署根证书

openssl x509 -req -in cert.csr -out rsa_public_key.der -outform der -signkey rsa_private_key.pem -days 3650
3、验证证书。把public_key.der拖到xcode中，如果文件没有问题的话，那么就可以直接在xcode中打开，看到证书的各种信息。
