【1】、Xcode8代碼出現(xiàn)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]

解決辦法：【product】-【scheme】-【Edit Scheme】-【Run】-【Argument】-【Environment Variable】添加keyValue【OS_ACTIVITY_MODE?? disable】可以停止輸出打印此日志

遺留問題：還會(huì)出現(xiàn)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.

【3】iOS10字體隱藏問題

label的話寫一個(gè)擴(kuò)展類

@implementation?UILabel?(Extend)??

???

-?(void)lableAdaptIOS10{??

???

????CGFloat?iOS10?=?[[UIDevice?currentDevice]?systemVersion].floatValue?>=?10;??

????if?(iOS10)?{??

//????????self????UIFont?的preferredFontForTextStyle:?意思是指定一個(gè)樣式，并讓字體大小符合用戶設(shè)定的字體大小。??

????????[self?sizeToFit];??

???

//??????self.font?=[UIFont?preferredFontForTextStyle:?UIFontTextStyleHeadline];???

????????//是否更新字體的變化??

//????????self.adjustsFontForContentSizeCategory?=?YES;??

????}??

}??

另外需要注意的是iOS10字體寬度比之前多一個(gè)像素，高度不變，這個(gè)是個(gè)坑，需要注意一下！

解決方法1:

在文件開頭加入 #ifdef DEBUG #define NSLog(FORMAT, ...) fprintf(stderr,"%s\n",[[NSString stringWithFormat:FORMAT, ##__VA_ARGS__] UTF8String]); #else #define NSLog(...) #endif 即可。

解決方法2:

第一步：

第二步：

第三步：

添加參數(shù)：

Name ：OS_ACTIVITY_MODE?

Value : ?disable

?[6]?xcode8莫名其妙crash

以前也會(huì)有這個(gè)問題，具體不清楚
命令行

xcrun?simctl?list?devices?|?grep?-v?'^[-=]'?|?cut?-d?"("?-f2?|?cut?-d?")"?-f1?|?xargs?-I?{}?xcrun?simctl?delete?"{}"??
