我想在UITableView的标题部分显示UIButton。这是我曾尝试设置按钮框架适合视图
UIView *headerView = [[UIView alloc] initWithFrame:CGRectMake(0,0, 285, 44)];
UIButton *headerViewButton = [UIButton buttonWithType:UIButtonTypeCustom];
headerViewButton.frame = CGRectMake(headerView.bounds.size.width * 7/5, headerView.bounds.size.height * 1/4, 320.0, 30.0);
headerViewButton.backgroundColor = [UIColor grayColor];
[headerViewButton setTitle:@"Import main list from other field >" forState:UIControlStateNormal];
[headerViewButton addTarget:self
action:@selector(buttonPressed:)
forControlEvents:UIControlEventTouchDown];
[headerView addSubview:headerViewButton];
的问题是我有调节按钮框很难,所以,它在横向模式适合精细以及肖像模式的代码。我对使用Interface Builder不太舒服。如何正确调整按钮框架以适合视图。
我一直在使用setAutoresizingMask
UIView *headerView = [[UIView alloc] initWithFrame:CGRectMake(0,0, 320, 44)];
UIButton *headerViewButton = [UIButton buttonWithType:UIButtonTypeCustom];
headerViewButton.frame = CGRectMake(headerView.bounds.size.width * 7/5, headerView.bounds.size.height * 1/4, 290, 30.0);
headerViewButton.backgroundColor = [UIColor grayColor];
[headerViewButton setTitle:@"Import main list from other field >" forState:UIControlStateNormal];
[headerViewButton addTarget:self
action:@selector(buttonPressed:)
forControlEvents:UIControlEventTouchDown];
[headerViewButton setAutoresizingMask:UIViewAutoresizingFlexibleRightMargin | UIViewAutoresizingFlexibleTopMargin|UIViewAutoresizingFlexibleWidth];
[headerView addSubview:headerViewButton];
由于应用程序加载的第一次,该按钮丢失试过,但我改变了方向,会出现按钮。每次尝试时,它都是一样的模式。应用程序第一次加载时,该按钮将丢失,并在此之后出现在两个方向上。
作为rmaddy指出,你设置奇怪的按钮位置:'headerViewButton.frame = CGRectMake(headerView.bounds.size.width * 7/5,headerView.bounds.size.height * 1/4,290,30.0) ;'所以'x = headerview.width * 1.4 = 320 * 1.4'这是屏幕外 – 2013-03-19 20:35:00
