初始化NSDictionary：（工作经验）两种方法有时候效果不一样

方法1:

NSMutableDictionary *dic = [[NSMutableDictionary alloc] init];

[dic setObject:[Hp_KeysArray objectAtIndex:_textField.tag] forKey:@"hpb_id"];

[dic setObject:[NSNumber numberWithInt:_currentPage] forKey:@"currentPage"];

[dic setObject:[NSNumber numberWithInt:_pageSize] forKey:@"pageSize"];

[dic setObject:_seachtextField.text forKey:@"addr"];

方法2:

NSDictionary *dic = [[NSDictionary alloc]initWithObjectsAndKeys:

[Hp_KeysArray objectAtIndex:_textField.tag] ,@"hpb_id",

_seachtextField.text,@"addr",

_currentPage,@"currentPage",

_pageSize,@"pageSize",

nil];
