iphone开发返回Documents Tmp 应用程序资源文件夹路径
大伙都知道iphone开发下要经常返回文件夹的路径,但是苹果提供的api返回不同的文件夹又不一样,我在这里统一定义下接口,
以后无论是返回Documents还是Tmp还是应用程序资源文件夹路径都只要直接调用:
- (NSString *)dataFilePath:(NSString *)file ofType:(int)kType{ NSString *pathFile = nil; switch (kType) { case kDocuments: { // NSDocumentDirectory代表查找Documents路径,NSUserDomainMask代表在应用程序沙盒下找 NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES); // ios下Documents文件夹只有一个 NSString *documentsDirectory = [paths objectAtIndex:0]; pathFile = [documentsDirectory stringByAppendingPathComponent:file]; break; } case kTmp: { NSString *str = NSTemporaryDirectory(); pathFile = [str stringByAppendingPathComponent:file]; break; } case kAPP: { // 获得文件名 NSString *str =[file stringByDeletingPathExtension]; // 获得文件扩展路径 NSString *str2 = [file pathExtension]; pathFile = [[NSBundle mainBundle] pathForResource:str ofType:str2]; break; } default: break; } return pathFile;}
