1.项目中出现了如下警告

警告

具体代码如下

self.navigationController.navigationBar.titleTextAttributes = 
[NSDictionary dictionaryWithObjectsAndKeys:BIMRGBA(51, 51, 51, 1), UITextAttributeTextColor,
 [UIFont systemFontOfSize:19], UITextAttributeFont,
 [UIColor clearColor], UITextAttributeTextShadowColor, nil];

具体如下：

'UITextAttributeFont' is deprecated: first deprecated in iOS 7.0 - Use NSFontAttributeName

'UITextAttributeTextColor' is deprecated: first deprecated in iOS 7.0 - Use NSForegroundColorAttributeName

'UITextAttributeTextShadowColor' is deprecated: first deprecated in iOS 7.0 - Use NSShadowAttributeName with an NSShadow instance as the value
这个一般一起出现。
修改如下，注意下NSShadow 的位置，不能直接用[UIColor clearColor] ，必须使用NSShadow 对象，否则crash。

正确代码如下：

  NSShadow *shadow = [[NSShadow alloc] init];
    shadow.shadowColor = [UIColor clearColor];
    shadow.shadowOffset = CGSizeMake(1,0);
    self.navigationController.navigationBar.titleTextAttributes = [NSDictionary dictionaryWithObjectsAndKeys:BIMRGBA(51, 51, 51, 1), NSForegroundColorAttributeName,
     [UIFont systemFontOfSize:19], NSFontAttributeName, 
     shadow, NSShadowAttributeName, nil];

2.关于warning: no rule to process file的问题

warning: no rule to process file '/Users/xx/ThirdParty/SDK-ThirdParty/TTTAttributedLabel/README.md' of type net.daringfireball.markdown for architecture i386
warning: no rule to process file '/Users/xx/ThirdParty/SDK-ThirdParty/TTTAttributedLabel/README.md' of type net.daringfireball.markdown for architecture x86_64

解决的方法很简单：在【build phases】—>【compile sources】 里面将对应的文件移除即可。

删除编译文件
