我正在使用这种方法,它的工作 100%
- (void) writeToPlist: (NSString*)fileName withData:(NSMutableArray *)data
{
NSString *documentsDirectory = [NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES) objectAtIndex:0];
NSString *finalPath = [documentsDirectory stringByAppendingPathComponent:fileName];
[data writeToFile:finalPath atomically: YES];
/* This would change the firmware version in the plist to 1.1.1 by initing the NSDictionary with the plist, then changing the value of the string in the key "ProductVersion" to what you specified */
}
以及这种从 plist 文件中读取的方法:
- (NSMutableArray *) readFromPlist: (NSString *)fileName {
NSString *documentsDirectory = [NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES) objectAtIndex:0];
NSString *finalPath = [documentsDirectory stringByAppendingPathComponent:fileName];
BOOL fileExists = [[NSFileManager defaultManager] fileExistsAtPath:finalPath];
if (fileExists) {
NSMutableArray *arr = [[NSMutableArray alloc] initWithContentsOfFile:finalPath];
return arr;
} else {
return nil;
}
}
希望它可以帮助你。
