一. 更換了友盟分享的第三方庫之后，就開始報這個警告或者是更新了bugtags的第三方之后，也會報這個警告
warning: Could not resolve external type c:objc(cs)NSObject

解決方法:
I had this problem too. Here's how I fixed it.
- Go to Build Settings -> Build Options -> Debug Information Format
- Change the Debug setting from "DWARF with dSYM File" to "DWARF"
- Leave the Release setting at "DWARF with dSYM File"
The problem appears to be that Xcode was trying to create dSYM files for Debug builds. You don't need dSYM files for Debug builds -- it's release builds where you need them.
二. Xcode7 中 directory not found for option 'xxxx' 警告
ld: warning: directory not found for option '-F/Applications/Xcode-beta.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS9.0.sdk/Developer/Library/Frameworks'
解決方法:
1選擇工程, 編譯的 (targets)
2選擇 Build Settings 菜單
3查找 Library Search Paths 和 Framework Search Paths， 刪掉編譯報warning的路徑即OK
