如何从文档目录中提取路径组件直到我的文件名？ [英] How to extract a path components from documents directory till my file name?

问题描述

在我的iPhone应用程式中，

我要提取路径元件....

  / Users / priyadarshanjoshi / Library / Application Support / iPhone Simulator / 5.0 / Applications / A2CD9285-62E9-4447-9945-5D8CE090FB3A / Documents / Wine_12.png 
  
 
 
 
我要提取
  Wine_12.png 
  
我正在编写此代码... 
 
 $ b 
  NSString * relativePathImage1 = @; 
 BOOL append = NO; 
 for（NSString * get in [imagePath pathComponents]）
 {
 if（[get isEqualToString：@Documents]）
 {
 append = YES; 
} 
 if（append == YES）
 {
 relativePathImage1 = [relativePathImage1 stringByAppendingPathComponent：get]; 
} 
} 
 NSLog（@relativePathImage1％@，relativePathImage1）; 
  
 
 
解决方案
为什么不帮助下面的函数？它将导致在一个数组中的2个字符串，在文档和after文档之前。然后可以使用字符串后的文档和附加文档/在相同的和使用它。 
  [strPath componentsSeparatedByString：@Document] 
  
 
In my iPhone Application,

I want to extract a path components....
/Users/priyadarshanjoshi/Library/Application Support/iPhone Simulator/5.0/Applications/A2CD9285-62E9-4447-9945-5D8CE090FB3A/Documents/Wine_12.png
I want to extract
/Documents/Wine_12.png
I am writing this code...

Is there any easier way to do the same?
NSString *relativePathImage1=@"";
        BOOL append=NO;
        for(NSString *get in [imagePath pathComponents])
        {
            if([get isEqualToString:@"Documents"])
            {
                append=YES;
            }
            if(append==YES)
            {
            relativePathImage1=[relativePathImage1 stringByAppendingPathComponent:get];
            }
    }
        NSLog(@"relativePathImage1 %@",relativePathImage1);

解决方案
why don't you take help of below function? It would result into 2 strings in an array,before document and after document. Yu can then use the string after document and append document/ in the same and use it.  
   [strPath componentsSeparatedByString:@"Document"]
