读取.plist文件的内容..

NSString* plistPath = [[NSBundle mainBundle] pathForResource:@"league" ofType:@"plist"];
contentArray = [NSArray arrayWithContentsOfFile:plistPath];

写入.plist文件。

NSMutableDictionary * myDictionary;
NSString* plistPath = [[NSBundle mainBundle] pathForResource:@"league" ofType:@"plist"];
[myDictionary writeToFile:plistPath atomically:YES];

注意：
字典必须包含 plist 对象（NSData、NSDate、NSNumber、NSString、NSArray 的实例代码> 或 NSDictionary）。并且字典键必须是 NSString 对象

Reading content of .plist file ..

NSString* plistPath = [[NSBundle mainBundle] pathForResource:@"league" ofType:@"plist"];
contentArray = [NSArray arrayWithContentsOfFile:plistPath];

Writing to .plist file.

NSMutableDictionary * myDictionary;
NSString* plistPath = [[NSBundle mainBundle] pathForResource:@"league" ofType:@"plist"];
[myDictionary writeToFile:plistPath atomically:YES];

Note that:
Dictionary must contain plist objects (instances of NSData, NSDate, NSNumber, NSString, NSArray, or NSDictionary). And dictionary keys must be NSString objects
