最佳回答

它通常最能读到文件上,因为它通常告诉你要做的事情。

阅读后,你可以看到,有一套系统,采用国家数据库系统。

你的最好之子大概就是这样。 假设你们想能够将图像用于各州。 否则,让我知道,我可以更新答案。

UIToolbar *toolbar = [[UIToolbar alloc] init];
NSMutableArray *arrayOfButtons = [NSMutableArray new];

UIImage *image = [UIImage imageNamed:@"image.png"];
UIBarButtonItem *button1 = [[UIBarButtonItem alloc] initWithImage:image style:UIBarButtonItemStyleBlack target:self action:@selector(doSomething)];

[array addObject:button1];

[toolbar setItems:arrayOfButtons];
