解決方法根第一個(gè)一樣
3.升級Xcode8之后弥奸，會(huì)打印一些煩人的Log信息承绸，隱藏不需要的Xcode8日志，
解決的辦法：就是設(shè)置 OS_ACTIVITY_MODE = disable勉盅，這樣做在模擬器上是正常的铆农，但是iOS10真機(jī)測試所有的Log日志全部被屏蔽了牺氨！這不是之前設(shè)置導(dǎo)致的，而是iOS10為了在真機(jī)上提高性能墩剖，所以把Log日志給屏蔽了猴凹。
解決方案：
自定義Log 需要用printf()進(jìn)行轉(zhuǎn)換，真機(jī)才能輸出日志
// 可以輸出純凈的內(nèi)容：NSLog去掉時(shí)間戳及其他輸出樣式#ifdefDEBUG#defineNNSLog(FORMAT, ...) fprintf(stderr,"%s\n",[[NSString stringWithFormat:FORMAT, ##__VA_ARGS__] UTF8String]);#else#defineNNSLog(...)#endif// 我推薦用這個(gè)打印我們的日志:功能岭皂、行數(shù)#ifdefDEBUG#defineNSSLog(FORMAT, ...) fprintf(stderr,"%s:%d\t%s\n",[[[NSString stringWithUTF8String:__FILE__] lastPathComponent] UTF8String], __LINE__, [[NSString stringWithFormat:FORMAT, ##__VA_ARGS__] UTF8String]);#else#defineNSSLog(...)#endif
3.報(bào)錯(cuò)：-[__NSCFNumber length]: unrecognized selector sent to instance
解決方案：
這個(gè)問題大部分是類型轉(zhuǎn)換錯(cuò)誤郊霎，檢查起來可能比較麻煩，個(gè)人聚的最好的辦法就是一個(gè)一個(gè)的控制器注釋爷绘，這樣查找問題也快很多
