我正在尝试将一些项目存储到pList中.这是数组循环：
@H_404_26@解决方法
for (id obj in items) NSLog(@"obj: %@",obj);
输出NSLog：
2013-03-27 13:00:40.072 mycode[47436:c07] obj: Red 2013-03-27 13:00:40.073 mycode[47436:c07] obj: Blue 2013-03-27 13:00:40.073 mycode[47436:c07] obj: Green
// arrayWithObjects有效.但我不知道如何(循环？)通过我的项目保存到plist文件…
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory,NSUserDomainMask,YES);
NSString *documentsDirectory = [paths objectAtIndex:0];
NSString *path = [documentsDirectory stringByAppendingPathComponent:@"data.plist"];
NSFileManager *filemgr;
filemgr = [NSFileManager defaultManager];
if ([filemgr fileExistsAtPath: path]) {
NSLog(@"%@",path);
NSMutableDictionary *plist = [[NSDictionary dictionaryWithContentsOfFile:path] mutableCopy];
NSMutableArray *newArray = [[[NSMutableArray alloc] init] autorelease];
newArray = [NSArray arrayWithObjects:@"Red",@"Green",@"Blue" nil]; // <--- WORKS!
newArray = [NSArray arrayWithObjects:items,nil]; // <-- ?
[plist setObject:newArray forKey:@"Hi"];
[plist writeToFile:path atomically:YES];
[plist release];
} else {
NSLog(@"File not found");
}
[filemgr release];
也许这段代码可以帮助你.
NSMutableArray *newArray = [[[NSMutableArray alloc] init] autorelease];
NSMutableArray *targetArray = [[[NSMutableArray alloc] init] autorelease];
newArray = [NSArray arrayWithObjects:@"Red",@"Blue" nil];
for(int i=0;i<newArray.count;i++)
{
[targetArray addObject:[newArray objectAtIndex:i]];
}
[plist setObject:targetArray forKey:@"Hi"];
[plist writeToFile:path atomically:YES];
或另一种方法
NSMutableArray *targetArray = [[[NSMutableArray alloc] init] autorelease];
for (id obj in items)
{
[targetArray addObject:items];
}
[plist setObject:targetArray forKey:@"Hi"];
[plist writeToFile:path atomically:YES];
希望这可以帮助 ！！！
