xcode debug

Use Xcode-debug and release modes, and xcode-debugrelease In the development process, we often need to use NSLog to output some information, or even some development processes, which must be viewed in the console, experienced programmers can use the console to output the entire data interaction process. However, a published program contains too many NSLog outputs

source of the crash produced.But in this case, we can only guess the error in which class, try to set a breakpoint on the code that might appear crash, step-by-step debugging to finally locate the line of code that really produces crash.This efficiency is obviously very low, there is no way to quickly locate the wrong specific location?Yes!Find show the breakpoint Navigator in our Xcode, set a global exception breakpoint as inWhen we run the program

If a exc_bad_access error occurs, it is basically due to a memory leak, an error release, and a release operation on an already freed object. But Xcode does not sometimes tell you where the error is (Visual Studio does it well). However, we can view the source of the error by setting the XCODE environment variable environment variable nszombieenabled,mallocstacklogging:1, Menu Product > Manage schemes;2, ch

DetailsDebug XcodeThe program is the content to be introduced in this article. Let's talk about it. There are two ways to solve the problem of long-standing debugging: first, brute force.DebuggingThe second is to use the debugger.Debugging. What is brute force debugging? Brute-force debugging adds NSLog to your program to output control processes and important data of the program to the terminal. Debugger debugging: The debugger is a program between the application you write and the operating sy

After XCode4.0, the compiler replaced the LLVM compiler 2.0More powerful than before:The 1.LLVM compiler is the next area of open source compilation technology. Fully supports C, objective-c, and C + +.The 2.LLVM is twice times faster than GCC, and the established program runs faster. Because it better utilizes the structure of the modern chip.The 3.LLVM and Xcode 4 are fully integrated. Including keyword highlighting, code integrity, and so on, are a
