iOS獲取App各種文件的路徑方法匯集

[super viewDidLoad];
    // 獲取App的Sandbox路徑
    NSString sandboxPath = NSHomeDirectory();
    NSLog(@"%@",sandboxPath);
    //獲取Documents路徑
    NSString doc = [sandboxPath stringByAppendingPathComponent:@"Documents"];
    NSLog(@"doc:%@",doc);
    //另一種獲取Documents路徑的方式
    NSArray paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
    NSString doc1 = [paths firstObject];
    NSLog(@"Doc:%@",doc1);


//獲取Library的路徑
NSString *lib = [NSSearchPathForDirectoriesInDomains(NSLibraryDirectory, NSUserDomainMask, YES) firstObject];
NSLog(@"%@",lib);

//獲取Library下的Caches目錄
NSString *caches = [NSSearchPathForDirectoriesInDomains(NSCachesDirectory, NSUserDomainMask, YES)firstObject];
NSLog(@"Caches:%@",caches);

//獲取臨時目錄下tmp
NSString *tmp = NSTemporaryDirectory();
NSLog(@"tmp:%@",tmp);

//如何獲取應用程序本身的路徑
NSBundle *mainBundle = [NSBundle mainBundle];//mainBundle 對象代表應用程序本身的內容
NSString *path = [mainBundle pathForResource:@"a" ofType:@"jpg"];
NSLog(@"%@",path);
//獲取Url
NSURL *url = [mainBundle URLForResource:@"a" withExtension:@"jpg"];
NSLog(@"url:%@",url);</pre>
