参考文章：http://www.2cto.com/kf/201301/186676.html

NSString * headerData = model.content;
headerData = [headerData stringByTrimmingCharactersInSet:[NSCharacterSet whitespaceAndNewlineCharacterSet]]; //去除掉首尾的空白字符和换行字符
headerData = [headerData stringByReplacingOccurrencesOfString:@” ” withString:@”“];
headerData = [headerData stringByReplacingOccurrencesOfString:@” ” withString:@”“];

    label.text = [NSString stringWithFormat:@"通知:%@",headerData];
