UILabel的簡單使用

UILabel * oper2=[[UILabelalloc] initWithFrame:CGRectMake(200,
100, 30, 30)];//初始化

    oper2.text=@"=";

    oper2.textColor=[UIColorblackColor];//字型為黑色

    oper2.backgroundColor=[UIColorclearColor];//清除背景顏色

    oper2.textAlignment=1;//字置中

    oper2.font=[UIFont
systemFontOfSize:25];
//字型的大小

    oper2.shadowOffset=CGSizeMake(2,
1);//陰影的位移位置

    oper2.shadowColor=[UIColorgrayColor];//陰影顏色

    [self.view
addSubview:oper2];//載入顯示

    [oper2 release];//記憶體管理

隨字數改變高度

//初始化UILable  用於顯示影院乘車路線

    UILabel * buslinelbl = [UILabel
labelWithFrame:CGRectMake(NUM_TEN,
NUM_TEN, SCREENFRAME_WIDTH-2*NUM_TEN,
100) text:[NSString
stringWithFormat:@"乘車路線：%@",[self.cinemaMessage
objectForKey:@"busline"]] textColor:[UIColor
whiteColor] setFont:[UIFont
systemFontOfSize:NUM_THIRTEEN]];

    buslinelbl.lineBreakMode
= NSLineBreakByCharWrapping;//設定自動換行

    buslinelbl.numberOfLines =
10;//設定行數

    CGSize size = CGSizeMake(buslinelbl.frame.size.width,200); 
//設定寬高，其中高為允許的最大高度

    CGSize labelsize = [buslinelbl.text
sizeWithFont:buslinelbl.font
constrainedToSize:size lineBreakMode:1];   
//通過文本_lblContent.text的字數，字型的大小，限制的高度大小以及模式來擷取label的大小

    [buslinelbl setFrame:CGRectMake(buslinelbl.frame.origin.x,buslinelbl.frame.origin.y,labelsize.width,labelsize.height)]; 
//最後根據這個大小設定label的frame即可

    [scroll addSubview:buslinelbl];//載入在滾動視圖上

CGSize size = CGSizeMake(_lblContent.frame.size.width,10000);  //設定寬高，其中高為允許的最大高度

CGSize labelsize = [_lblContent.text sizeWithFont:_lblContent.font constrainedToSize:size lineBreakMode:UILineBreakModeWordWrap];    //通過文本_lblContent.text的字數，字型的大小，限制的高度大小以及模式來擷取label的大小

[_lblContent setFrame:CGRectMake(_lblContent.frame.origin.x,_lblContent.frame.origin.y,labelsize.width,labelsize.height)];  //最後根據這個大小設定label的frame即可

UIFont 設定字型

label.font = [UIFont fontWithName:@"Arial-BoldItalicMT" size:24];
