You can use NSAssert() to debug your code, just like NSLog().

i.e.

NSAssert(X <= 0, @"x must large than zero!");

 

 

If x<=0 return NO , it will throw exception.You can see a message "x must large than zero!", and also other related details.

 

 

调试cocoa程序在程序出错时，不会马上停止。使用宏NSAssert可以让程序出错时马上抛出异常。
在debug情况下，所有NSAssert都会被执行。在release下不希望NSAssert被执行，我们通常在release种将断言设置成禁用。
设置方法：在targets种选择build，选择release。在gcc preprocessing下增加Preprocessor Macros 值为 NS_BLOCK_ASSERTIONS.

IOS 使用NSAssert()和NSParameterAssert调试程序

`NSAssert()`和`NSParameterAssert()`是Apple提供的两种强大的调试工具，它们可以帮助开发者在开发阶段快速定位并修复问题。下面我们将详细探讨这两个宏的使用方法和作用。 首先，`NSAssert()`是一个用于调试目的的...

前言任何代码都会发生错误，这些错误有些是可以补救的，有些则只能让程序崩溃。良好的错误处理能够让你的代码健壮性提高，提高程序的稳定性。本文的Swift版本：Swift 3Objective C返回nil如果出错了，就返回空是Objective C中的一种常见的处理方式。因为在Objective C中，向nil发送消息是安全的。比如：- (instancetype)init { self = [

NSAssert()是一个宏，用于开发阶段调试程序中的Bug，通过为NSAssert()传递条件表达式来断定是否属于Bug，满足条件返回真值，程序继续运行，如果返回假值，则抛出异常，并且可以自定义异常描述。 NSAssert()是这样定义的： #define NSAssert(condition, desc) condition是条件表达式，值为YES或NO；desc为异常描述，通常为NS

今天突然发现了一个开发ios程序时调试的好帮手—NSAssert()函数。而且和NSLog()函数一样简单易用，代码如下： NSAssert(x!=0,@”x must not be zero”); 在表达式“x!=0”不成立时，程序就会抛出异常，并显示自定义的消息”x must not be zero”，并同时显示出错的文件、代码和调用函数等信息，是一个程序追踪的很好手段。 ...

苹果在foundation.framework中定义了这么一个宏： #define NSAssert(condition, desc, ...) 第一个参数为一个条件判断，如果为假，则抛出异常，显示第二个参数所描述的信息。 例如 NSAssert(2>=4.4, @"2>=4.4 is false!"); 在debug模式下运行，会终止程序，并抛出如下异常： 2

断言（assertion）是指在开发期间使用的、让程序在运行时进行自检的代码（通常是一个子程序或宏）。断言为真，则表明程序运行正常，而断言为假，则意味着它已经在代码

NSAssert()只是一个宏，用于开发阶段调试程序中的Bug，通过为NSAssert()传递条件表达式来断定是否属于Bug，满足条件返回真值，程序继续运行，如果返回假值，则抛出异常，并切可以自定义异常描述。NSAssert()是这样定义的： #define NSAssert(condition, desc) condition是条件表达式，值为YES或NO；desc为异常描述，通常为NSSt...

开发ios程序时调试的好帮手---NSAssert()函数。而且和NSLog()函数一样简单易用，代码如下：    NSAssert(x!=0,@"x must not be zero"); 在表达式“x!=0”不成立时，程序就会抛出异常，并显示自定义的消息"x must not be zero"，并同时显示出错的文件、代码和调用函数等信息，是一个程序追踪的很好手段。 假设x!=0，不

NSAssert在debug下生效，在release下不起作用的。通常我们用下图切换版本模式： 但在时常所有工作又都在debug下完成，有什么办法，在debug版本下也能禁用NSAssert呢？答案就是定义NS_BLOCK_ASSERTIONS宏，但是简单添加#define NS_BLOCK_ASSERTIONS，是起不了作用的，解决办法如下： ...

NSAssert断言的使用，即可以使用NSAssert进行变量等的异常判断，在开发环境中避免代码异常，造成在真机中使用时造成闪退。 作用相当于对变量使用条件语句进行有效判断。 使用NSAssert断言时，如果非真时，在模拟器会停止继续运行，且跳转到异常代码处；而在真机中则不会。 NSAssert(self.fileKey != nil, @"fileKey must be not n
