我有一個問題:我可以'找到一種方法來正確保存我的UITextView在NSString中。 我已經創建了4個UITextViews,我希望它們被保存在同一個文件中。 繼承人的代碼:從UITextVIEW保存文本?
-(void)destinataireTextView {
self.destiView = [[[UITextView alloc] initWithFrame:CGRectMake(200, 160, 150, 120)] autorelease];
[self.view addSubview: self.destiView];
}
-(void)expediteurTextView {
self.expediView = [[[UITextView alloc] initWithFrame:CGRectMake(430, 200, 150, 120)] autorelease];
[self.view addSubview: self.expediView];
}
-(void)objetTextView {
self.objetView = [[[UITextView alloc] initWithFrame:CGRectMake(200, 295, 150, 120)] autorelease];
[self.view addSubview: self.objetView];
}
-(void)corpsTextView {
self.corpsView = [[[UITextView alloc] initWithFrame:CGRectMake(200, 335, 150, 120)] autorelease];
[self.view addSubview: self.corpsView];
}
-(void)viewDidLoad{
[super viewDidLoad];
[self destinataireTextView];
[self expediteurTextView];
[self objetTextView];
[self corpsTextView];
}
I've tried this piece of code :
-(void)viewDidLoad
[super viewDidLoad];
NSString *filePath = [self pathOfFile];
if ([[NSFileManager defaultManager]fileExistsAtPath:filePath]) {
NSArray *array = [[NSArray alloc] initWithContentsOfFile:filePath];
desti.text = [array objectAtIndex:0];
[array release];
}
UIApplication *notif = [UIApplication sharedApplication];
[[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(applicationWillTermite:) name:UIApplicationWillTerminateNotification object:notif];
}
-(NSString *) pathOfFile{
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentFolder = [paths objectAtIndex:0];
return [documentFolder stringByAppendingFormat:@"SaveData.plist"];
}
-(void)applicationWillTermite:(NSNotification *)notification{
NSMutableArray *save = [[NSMutableArray alloc] init];
[save addObject:field1.text];
[save writeToFile:[self pathOfFile]atomically:YES];
[save release];
}
我迫切需要幫助。

我不知道你的應用程序,但我從來沒有'白蟻的。錯字?或者你的問題的原因? – 2010-10-22 09:29:40
