本文介绍了保存Array对的plist的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!
问题描述
我想一些项目存储到的plist
。这里是阵列环
为(以项目ID OBJ)
的NSLog(@OBJ:%@,OBJ);
输出的NSLog:
2013年3月27日13:00:40.072我的code [47436:C07] OBJ:红
2013年3月27日13:00:40.073我的code [47436:C07] OBJ:蓝
2013年3月27日13:00:40.073我的code [47436:C07] OBJ:绿
//该arrayWithObjects的作品。但我不知道如何(循环?)通过我的物品保存到plist文件...
的NSArray *路径= NSSearchPathForDirectoriesInDomains(NSDocumentDirectory,NSUserDomainMask,YES);
的NSString * documentsDirectory = [路径objectAtIndex:0];
* NSString的路径= [documentsDirectory stringByAppendingPathComponent:@data.plist];
*的NSFileManager filemgr;
filemgr =的NSFileManager defaultManager] 如果([filemgr fileExistsAtPath:路径]){
的NSLog(@%@,路径); *的NSMutableDictionary =的plist [[NSDictionary的dictionaryWithContentsOfFile:路径] mutableCopy]
NSMutableArray里* newArray = [[[NSMutableArray里的alloc]初始化]自动释放];
newArray = [NSArray的arrayWithObjects:@红,@绿色,@蓝无]。 //< --- WORKS!
newArray = [NSArray的arrayWithObjects:项目,无] //<? -
[plist中的setObject:newArray forKey:@你好];
[的plist将writeToFile:路径原子:YES];
[plist中释放];
}其他{
的NSLog(@找不到文件);
} [filemgr发布]
解决方案
也许这块code的帮助你。
的NSMutableArray * newArray = [[[NSMutableArray里的alloc]初始化]自动释放];
NSMutableArray里* targetArray = [[[NSMutableArray里的alloc]初始化]自动释放];newArray = [NSArray的arrayWithObjects:@红,@绿色,@蓝无]。
的for(int i = 0; I< newArray.count;我++)
{
[targetArray ADDOBJECT:[newArray objectAtIndex:我]];}
[plist中的setObject:targetArray forKey:@你好];
[的plist将writeToFile:路径原子:YES];
或另一种方法
的NSMutableArray * targetArray = [[[NSMutableArray里的alloc]初始化]自动释放];为(以项目ID OBJ)
{
[targetArray ADDOBJECT:项目];
}
[plist中的setObject:targetArray forKey:@你好];
[的plist将writeToFile:路径原子:YES];
希望这有助于!
I'm trying to store some items into a pList
. Here is the array loop:
for (id obj in items)
NSLog(@"obj: %@", obj);
Output 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
// The arrayWithObjects works. But I don't know how to (loop?) through my items for saving into the plist file...
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];
解决方案
Maybe this piece of code helps you.
NSMutableArray *newArray = [[[NSMutableArray alloc] init] autorelease];
NSMutableArray *targetArray = [[[NSMutableArray alloc] init] autorelease];
newArray = [NSArray arrayWithObjects:@"Red", @"Green", @"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];
or another method
NSMutableArray *targetArray = [[[NSMutableArray alloc] init] autorelease];
for (id obj in items)
{
[targetArray addObject:items];
}
[plist setObject:targetArray forKey:@"Hi"];
[plist writeToFile:path atomically:YES];
Hope this helps !!!
