基本屬性、方法如上,大家在實際開發中可根據實際需求選取適當屬性和方法。
使用技巧:
在導航欄中添加UISegmentedControl ,實現的效果:
實現的代碼:
//自定義UISegmentedcontrol
UISegmentedControl *segmentedControl=[[UISegmentedControl alloc] initWithFrame:CGRectMake(80.0f, 8.0f, 200.0f, 30.0f) ];
[segmentedControl insertSegmentWithTitle:@"Food to eat" atIndex:0 animated:YES];
[segmentedControl insertSegmentWithTitle:@"Food to avoid" atIndex:1 animated:YES];
segmentedControl.segmentedControlStyle = UISegmentedControlStyleBar;
segmentedControl.momentary = YES;
segmentedControl.multipleTouchEnabled=NO;
[segmentedControl addTarget:self action:@selector(Selectbutton:) forControlEvents:UIControlEventValueChanged];
UIBarButtonItem *segButton = [[UIBarButtonItem alloc] initWithCustomView:segmentedControl]; //自定義UIBarButtonItem,封裝定義好的UIsegmented。
[segmentedControl release];
self.navigationItem.rightBarButtonItem = segButton; //添加到導航欄中
[segButton release];
