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
