读写plist文件的奇怪问题
|
我有一个从plist文件读取信息的应用程序。为此，我使用以下代码：
NSData *plistData;
NSString *error;
NSPropertyListFormat format;
id plist;
localizedPath = [[NSBundle mainBundle] pathForResource:@\"settings\" ofType:@\"plist\"];
plistData = [NSData dataWithContentsOfFile:localizedPath];
plist = [NSPropertyListSerialization propertyListFromData:plistData mutabilityOption:NSPropertyListImmutable format:&format errorDescription:&error];
if (!plist) {
NSLog(@\"Error reading plist from file \'%s\', error = \'%s\'\", [localizedPath UTF8String], [error UTF8String]);
[error release];
}
NSString *tel=[NSString stringWithFormat:@\"tel:%@\",[plist objectForKey:@\"number\"]];
NSURL *telephoneURL = [NSURL URLWithString:tel];
[[UIApplication sharedApplication] openURL:telephoneURL];
- (IBAction) saveSetting:(id)sender{
NSData *plistData;
NSString *error;
NSPropertyListFormat format;
id plist;
NSString *localizedPath = [[NSBundle mainBundle] pathForResource:@\"settings\" ofType:@\"plist\"];
plistData = [NSData dataWithContentsOfFile:localizedPath];
plist = [NSPropertyListSerialization propertyListFromData:plistData mutabilityOption:NSPropertyListMutableContainers format:&format errorDescription:&error];
if (!plist) {
NSLog(@\"Error reading plist from file \'%s\', error = \'%s\'\", [localizedPath UTF8String], [error UTF8String]);
[error release];
}
NSLog([plist objectForKey:@\"message\"]);
[plist setValue:textMex.text forKey:@\"message\"];
NSLog([plist objectForKey:@\"message\"]);
NSLog([plist objectForKey:@\"number\"]);
[plist setValue:textNumero.text forKey:@\"number\"];
NSLog([plist objectForKey:@\"number\"]);
[plist setValue:@\"NO\" forKey:@\"firstTime\"];
[plist writeToFile:localizedPath atomically:YES];
[self aggiorna];
[settingScreen removeFromSuperview];
}

NSArray *paths = NSSearchPathForDirectoriesInDomains(NSLibraryDirectory, NSUserDomainMask, YES); NSString libraryPath = [paths objectAtIndex:0]; NSString plistPath = [libraryPath stringByAppendingPathComponent:@\"settings.plist\"]; // Checks if the file exists at the writable location. if ( ![[NSFileManager defaultManager] fileExistsAtPath:plistPath] ) { NSString *masterFilePath = [[NSBundle mainBundle] pathForResource:@\"settings\" ofType:@\"plist\"]; // Try to copy the master file to the writable location NSError *error; if ( ![[NSFileManager defaultManager] copyItemAtPath:masterFilePath toPath:plistPath error:&error] ) { NSLog(@\"Error: %@\", [error localizedDescription]); // Serious error. } } ... // Ready for use. NSData *plistData = [NSData dataWithContentsOfFile:plistPath];
