我正在检查目录是否存在,但我收到警告
不兼容的整数到指针转换发送'BOOL'(又名'签名' char')到'BOOL *'类型的参数(又名'signed char *')
BOOL isFile ;
isFile = [[NSFileManager defaultManager] fileExistsAtPath:[dirurl path] isDirectory:YES];
为什么我会收到此警告以及如何解决此问题
答案 0 :(得分:9)
像这样使用:
BOOL isDir;
BOOL isFileExists;
isFileExists = [[NSFileManager defaultManager] fileExistsAtPath:[dirurl path] isDirectory:&isDir];
if (isDir) {...}
官方文档示例developer.apple.com:
NSArray *subpaths;
BOOL isDir;
NSArray *paths = NSSearchPathForDirectoriesInDomains
(NSLibraryDirectory, NSUserDomainMask, YES);
if ([paths count] == 1) {
NSFileManager *fileManager = [[NSFileManager alloc] init];
NSString *fontPath = [[paths objectAtIndex:0] stringByAppendingPathComponent:@"Fonts"];
if ([fileManager fileExistsAtPath:fontPath isDirectory:&isDir] && isDir) {
subpaths = [fileManager subpathsAtPath:fontPath];
// ...
[fileManager release];
