If the developer is not familiar with the functionality of these methods and the parameters, they can use the Help Documentation. So how does the help text open and find the relevant content? The following will solve these problems for YOU.1. Open the Help documentto Use the Help text, you must open it.

There are several steps you need to implement to debug in Xcode :1. Add a breakpoint before proceeding with program debugging, you first need to add a breakpoint to the Program. Breakpoints are places where the debugger stops the program and allows developers to see it. Move the cursor to where you want to add a breakpoint, press and hold command+\ in the menu bar. degbug| breakpoints| Add breakpoint at the current line "command for adding breakpoints, You will then see a blue arrow at the far left of the Add breakpoint code, which is a new breakpoint, 1.76 Figure 1.76 Add Breakpoint2. running the programWhen you click the Run button, the program runs, and the running program stays at the point where the breakpoint is located, and the code line appears with a green arrow indicating where the program is now running, 1.77 is Shown. Not only that, but theiOS emulator will also be displayed, but there is no content. Figure 1.77 Run the program3. Breakpoint Navigationafter the program stops, the Program Debugging Information window will appear, which shows some debugging Information. At the top of the program debugging information window, a breakpoint navigation appears, as shown in1.78 . Figure 1.78 Navigation <ul class=" list-paddingleft-2" style="margin:0px; width:656.4375px; padding-left:30px; font-family:微软雅黑,Verdana,sans-serif,宋体; font-size:12.5px"> <li style="clear:both"><li style="clear:both">q Toggle Global Breakpoint state Button: Select the thread you want to VIEW. </li></li> <li style="clear:both"><li style="clear:both">q Continue Program Execution button: resumes execution of the current code and, if there is a next breakpoint, stops at the next Breakpoint. </li></li> <li style="clear:both"><li style="clear:both">q Step over Button: executes the next Code. If the current row is a method call, it does not go inside the Method. </li></li> <li style="clear:both"><li style="clear:both">q Step into Button: Enter the method Content. </li></li> <li style="clear:both"><li style="clear:both">q Step out Button: skips the current method, i.e. executes to the end of the current method. </li></li> </ul>at this point in the breakpoint navigation, click Continue Program Execution button to continue executing the current Code. If there is an error at this point, the program will not jump to the next breakpoint, or the program will continue to execute if there is no problem. Now there is only one breakpoint, click this button and the program will output the final Result. 4. Delete or discard breakpointsIf the program is not a problem, then the breakpoints set in the program should be deleted or Discarded. There are three ways to remove a breakpoint long: <ul class=" list-paddingleft-2" style="margin:0px; width:656.4375px; padding-left:30px; font-family:微软雅黑,Verdana,sans-serif,宋体; font-size:12.5px"> <li style="clear:both"><li style="clear:both">q Right-click on the set breakpoint and select delete Breakpoint command. </li></li> <li style="clear:both"><li style="clear:both">q Select the line where the breakpoint is set, and in xcode menu bar Select debug| breakpoints| Remove breakpoint at current line command. </li></li> <li style="clear:both"><li style="clear:both">q Select a breakpoint and drag it somewhere else. At this point, the breakpoint is Deleted. </li></li> </ul>to discard a breakpoint, click the Breakpoint. At this point, the breakpoint is changed from dark blue to light Blue. A light blue breakpoint indicates that the breakpoint has been discarded, as shown in1.79 .
