-(void)Uiconfig{

NSArray*arr = [[NSArrayalloc]initWithObjects:@"學(xué)生",@"老師",nil];

//先創(chuàng)建一個數(shù)組用于設(shè)置標(biāo)題

UISegmentedControl*segment = [[UISegmentedControlalloc]initWithItems:arr];

//在沒有設(shè)置[segment setApportionsSegmentWidthsByContent:YES]時(shí)，每個的寬度按segment的寬度平分

[segmentsetTintColor:[UIColorcolorWithHexString:@"#ff6121"]];//設(shè)置segments的顏色

segment.selectedSegmentIndex=0;

segment.frame=CGRectMake(0,0,100,30);

self.navigationItem.titleView= segment;

[segmentaddTarget:selfaction:@selector(change:)forControlEvents:UIControlEventValueChanged];

//當(dāng)選中不同的segment時(shí)，會執(zhí)行change:方法

//設(shè)置frame

}

-(void)change:(id)sender{

UISegmentedControl* control = (UISegmentedControl*)sender;

switch(control.selectedSegmentIndex) {

case0:

DLog(@"學(xué)生");

break;

case1:

DLog(@"老師");

break;

default:

break;

}

效果如下
