斷點(diǎn)
1.添加斷點(diǎn)
1.給test1函數(shù)添加斷點(diǎn)（C函數(shù)）set 是子命令， -n 是選項(xiàng)，是--name 的縮寫(xiě)：????????
????????????breakpoint set -n test1
2.給系統(tǒng)所有這個(gè)方法加斷點(diǎn): ???????????????????
??????????breakpoint set --selector touchesBegan:withEvent:
3.指定文件 的某個(gè)方法添加斷點(diǎn): ??????????????
? ? ? ? ? ?breakpoint set --file ViewController.m --selector touchesBegan:withEvent:
4.給ViewController類(lèi)里面的三個(gè)方法添加斷點(diǎn) ? ??????????
????????breakpoint?set -n "-[ViewController save:]" -n "-[ViewController pauseGame:]" -n "-[ViewController continueGame:]"
5.遍歷整個(gè)項(xiàng)目中滿足Game:這個(gè)字符的所有方法添加斷點(diǎn)：???????
?????????breakpoint set -r Game:
6.遍歷整個(gè)項(xiàng)目中滿足?hank?這個(gè)字符的所有方法：????????
?????????breakpoint set -r hank
????????b ?hank
7.給指定類(lèi)添加方法 ? 敲 ? ? ? ? b hankT ? ? ? ?就會(huì)出現(xiàn)提示，回車(chē)即可
????????b -[ViewController hankTest1:]
2.刪除斷點(diǎn)（只能刪除某一組）
刪除第1組斷點(diǎn)：????breakpoint delete 1
刪除所有斷點(diǎn)：????breakpoint delete
breakpoint delete 1.1????輸出：0 breakpoints deleted; 1 breakpoint locations disabled. ?沒(méi)有斷點(diǎn)被刪除，只是被禁用
3.啟用/禁用斷點(diǎn) ?enable/disable ?en/dis
啟用第1組斷點(diǎn)：breakpoint enable 1????????????????????簡(jiǎn)寫(xiě)：break? en?1 ? ?
啟用 第1組的第1個(gè)斷點(diǎn)：breakpoint enable 1.1
?禁用所有斷點(diǎn)：breakpoint disable ? ??? ? ? ? ????????? 簡(jiǎn)寫(xiě)：break? dis ??
4.查看斷點(diǎn)列表
breakpoint list
5.流程控制
繼續(xù)執(zhí)行(continue的簡(jiǎn)寫(xiě)) ??c ? ? ??
單步運(yùn)行,將子函數(shù)當(dāng)做整體一步執(zhí)行(next的簡(jiǎn)寫(xiě))? ?n
單步運(yùn)行,遇到子函數(shù)會(huì)進(jìn)去????????s
6.查看幫助
breakpoint help
p/expression 用法
????????????expression self.view.subviews
????????????po self.view.subviews?? ?
????????????p self.view.subviews
????????????p 是?expression 的簡(jiǎn)寫(xiě)
po? ?調(diào)用oc的description方法
更改背景顏色????????????p self.view.backgroundColor = [UIColor redColor]
調(diào)出斷點(diǎn)函數(shù)調(diào)用棧????????????bt
斷點(diǎn)回退指令 ?回到調(diào)用這個(gè)方法的地方????????????????up ? ? ?down
?代碼回退到上一個(gè)調(diào)用的地方，然后return掉 ? ? ? ? ? ? ? thread return
//可以設(shè)置成功
p (Person*)self.models.lastObject
p $7.name = @“hnak"
調(diào)出斷點(diǎn)函數(shù)調(diào)用棧????????????????bt
斷點(diǎn)回退/前進(jìn)指令 ,回到調(diào)用這個(gè)方法的地方 ????????????? ?up ????????down
回到函數(shù)調(diào)用棧的某一個(gè) ? ?定位到某個(gè)方法的具體調(diào)用位置 ???frame select 3
打印出整個(gè)函數(shù)的參數(shù) ? ?frame variable

command + shift + M ?可查看內(nèi)存存儲(chǔ)情況
breakpoint set --file ViewController.m --selector? touchesBegan:withEvent:
Breakpoint 1: where = 001--LLDB`-[ViewController touchesBegan:withEvent:] + 92 at ViewController.m:86, address = 0x0000000104bee3b0
?po self.models
p [self.models addObject:[[Person alloc]init]]
po self.models
p (Person*)self.models[3]?
????????????????(Person *) $2 = 0x00000001c0220d80
p $2.name
????????????????(NSString *) $3 = nil
p $2.name = @"xiaoming"
????????????????(NSTaggedPointerString *) $4 = 0xa006412031812da8 @"xiaoming"
po $2.name
????????????????xiaoming ? ?????????
po $2.age =? 254
????????????????254 ? ?????
po $2
????????????????<Person:?0x1c0220d80>
po sizeof($2)
????????????????8 ? ?????
?control + 回車(chē)。可以代碼換行
p Person *p5 = [[Person alloc]init];
p5.name = @"我是p5";
p5.age = 31;
[self.models addObject:p5];
p (Person *)self.models[4]
? ??????????????(Person *) $14 = 0x00000001c0221ac0
p (Person *)self.models.lastObject
????????????????(Person *) $5 = 0x00000001c0224ba0
? 打印對(duì)象地址 ? p $5
????????????????(Person *) $5 = 0x00000001c0224ba0 ? ?????????
p $5.age
????????????????(int) $6 = 256
po $6
????????????????256
設(shè)置對(duì)象屬性值 ?p $5.age = 19
獲取對(duì)象字節(jié)大小 ? ? ? po sizeof($6)
????????????????4
取地址 ? ? ? ? ? ? ??p &($6)
????????????????0x00000001034b46f0 ? ?????
添加斷點(diǎn)，當(dāng)改變p1的value值時(shí)斷住
watchpoint set variable p1->_name
打印出內(nèi)存存儲(chǔ)的值
po 0x0000000100620198
給第一組斷點(diǎn)添加代碼 ? ?????????break command add 1
查看command列表 ? ? ? ? ? ? ? ? ?breakpoint command list 1
調(diào)試數(shù)組越界奔潰
調(diào)用[self test2];函數(shù)。
image lookup -a 0x183c53fd8
可打印 出異常的棧調(diào)用
