问题描述
我编写了这小段代码以写入plist文件.我没有从XCode收到任何错误或警告,所以我真的迷路了.此代码节中未定义根",但这只是我从plist中提取的数据的字典.
I wrote this small bit of code to write to a plist file. I am not getting any errors or warnings from XCode, so I am really lost. "Root" is not defined in this code section, but it is just a dictionary of the data that I pulled from the plist.
有人知道为什么不将其写入plist文件吗?它实际上根本不会更改文件.
Does anyone have an idea of why this would not write to a plist file? It literally does not change the file at all.
NSMutableArray *newReports = [[NSMutableArray alloc] init];
newReports = [[Root objectForKey:@"Reports"] mutableCopy ];
//Creating data model for new report
NSMutableDictionary *newReport = [[NSMutableDictionary alloc] init];
NSString *tempTitle = titleField.text;
NSString *tempEmployee = employeeField.text;
NSArray *tempNodes = [[NSArray alloc] init];
[newReport setObject:tempTitle forKey:@"Title"];
[newReport setObject:tempEmployee forKey:@"Employee"];
[newReport setObject:tempNodes forKey:@"Nodes"];
[newReports addObject:newReport];
NSMutableDictionary *newRoot = [[NSMutableDictionary alloc] init];
[newRoot setObject:newReports forKey:@"Reports"];
//Writing data to plist
NSString *Path = [[NSBundle mainBundle] bundlePath];
NSString *filePath = [Path stringByAppendingPathComponent:@"data.plist"];
[newRoot writeToFile:filePath atomically: YES];

推荐答案
尝试像这样构建文件路径
try constructing your file path like this
NSArray *paths = NSSearchPathForDirectoriesInDomains( NSDocumentDirectory,
NSUserDomainMask, YES);
NSString *documentsDirectoryPath = [paths objectAtIndex:0];
NSString *filePath = [documentsDirectoryPath
stringByAppendingPathComponent:@"data.plist"];
[newRoot writeToFile:filePath atomically: YES];
