iOS10 Xcode8适配7个常见问题汇总

ios10 xcode8问题汇总

【1】、xcode8代码出现ubsystem: com.apple.uikit, category: hideventfiltered, enable_level: 0, persist_level: 0, default_ttl: 0, info_ttl: 0, debug_ttl: 0, generate_symptoms: 0, enable_oversize: 1, privacy_setting: 2, enable_private_data: 0 2016-09-14 17:18:55.843428 myapp[6880:340837]

解决办法： 【product】-【scheme】-【edit scheme】-【run】-【argument】-【environment variable】添加keyvalue【os_activity_mode   disable】可以停止输出打印此日志

遗留问题：还会出现class plbuildversion is implemented in both /applications/xcode.app/contents/developer/platforms/iphonesimulator.platform/developer/sdks/iphonesimulator.sdk/system/library/privateframeworks/assetslibraryservices.framework/assetslibraryservices (0x10a39a910) and /applications/xcode.app/contents/developer/platforms/iphonesimulator.platform/developer/sdks/iphonesimulator.sdk/system/library/privateframeworks/photolibraryservices.framework/photolibraryservices (0x10a1c4210). one of the two will be used. which one is undefined.

【2】mjrefresh出现崩溃现象 

 解决办法：类库增加判断

if (range.location != nsnotfound) {
   language = [language substringtoindex:range.location];
} 

【3】ios10字体隐藏问题

label的话写一个扩展类

@implementation uilabel (extend)
 
- (void)lableadaptios10{
 
 cgfloat ios10 = [[uidevice currentdevice] systemversion].floatvalue >= 10;
 if (ios10) {
//  self uifont 的preferredfontfortextstyle: 意思是指定一个样式，并让字体大小符合用户设定的字体大小。
  [self sizetofit];
 
//  self.font =[uifont preferredfontfortextstyle: uifonttextstyleheadline]; 
  //是否更新字体的变化
//  self.adjustsfontforcontentsizecategory = yes;
 }
}

 [4] stroyboard问题

<1>xcode 打开sb频繁出现崩溃现象

<2>xcode 打开sb后 约束出现大量警告⚠️

【5】xcode8注释失效

打开终端，命令运行： sudo /usr/libexec/xpccachectl 重启电脑

【6】xcode7 8兼容问题

this version does not support documents saved in the xcode 8 format. open this document with xcode 8.0 or later.

删除sb中代码：

【7】xcode8不能真机打印log问题

#ifdef debug
#define hystring [nsstring stringwithformat:@"%s", __file__].lastpathcomponent
#define hylog(...) printf("%s 第%d行: %s\n\n", [hystring utf8string] ,__line__, [[nsstring stringwithformat:__va_args__] utf8string]);
 
#else
#define hylog(...)
#endif
