数组新添加法

NSMutableArray *mArray = [NSMutableArray new];

for (int i = 0; i < 3; i ++) {

[mArray addObject:@[@"one",@"tow",@"three"][i]];

}

输出mArray：@"one",@"tow",@"three"

NSDictionary *tempDict = @{@"expand3":@{@"res":@{@"time": @"2013-10-31"}}};

NSLog(@"expand3.res = %@ time = %@",[tempDict valueForKeyPath:@"expand3.res"],[tempDict valueForKeyPath:@"expand3.res.time"]);

输出@"2013-10-31"
