为什么在iphone应用程序中保存NSArray总是失败
我想保存为什么在iphone应用程序中保存NSArray总是失败,iphone,ios,objective-c,Iphone,Ios,Objective C,我想保存NSArray，但它失败了，为什么 -(void)SaveDataAll:(NSMutableArray *)dataToSave:(NSString *)name { NSArray *array = [NSArray arrayWithArray:dataToSave]; // save path NSArray *paths = NSSearchPathForDirectoriesInDoma
NSArray -(void)SaveDataAll:(NSMutableArray *)dataToSave:(NSString *)name
{
NSArray *array = [NSArray arrayWithArray:dataToSave];
// save path
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory,
NSUserDomainMask, YES);
if ([paths count] > 0)
{
// Array path
NSString *arrayPath = [[paths objectAtIndex:0]
stringByAppendingPathComponent:name];
NSLog(@"SaveDataAll array====%@",array);
NSLog(@"SaveDataAll dataToSave====%@",dataToSave);
// save array
[array writeToFile:arrayPath atomically:YES];
// getout
NSArray *arrayFromFile = [NSArray arrayWithContentsOfFile:arrayPath];
NSLog(@"SaveDataAll ====%@",arrayFromFile);
}
}
