问题描述
我遇到了问题：我可以找到一种方法在NSString中正确保存我的UITextView。
我创建了4个UITextViews，我希望它们保存在同一个文件中。
下面代码：
I'm having a problem : i can' find a way to save properly my UITextView in a NSString.I have created 4 UITextViews and i want them to be saved in the same file.Heres the code :
-(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];
}
我迫切需要帮助。
Thx
推荐答案
你真的没有给我们太多的帮助。没有错误消息。没有关于你尝试过什么或失败的建议。
You don't really give us much to go on. No error messages. No suggestion of what you've tried or where it failed.
我的猜测是这一行：
return [documentFolder stringByAppendingFormat:@"SaveData.plist"];
我想你可能意味着：
return [documentFolder stringByAppendingPathComponent:@"SaveData.plist"];
否则你的文件名看起来像 /some/pathSaveData.plist ，显然无效。
Otherwise your filename will look something like /some/pathSaveData.plist, which, obviously, is not valid.
