我正在尝试将一些项目存储到pList中.这是数组循环:
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];
解决方法
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 !!!
