10:button显示设置不同字体
[_headerFansCountBtn setAttributedTitle:[self getStringWithTitle:@"粉丝"andValue:_curUser.fans_count.stringValue] forState:UIControlStateNormal];
方法(根据长度来设置其不同的样式显示):- (NSMutableAttributedString*)getStringWithTitle:(NSString *)title andValue:(NSString *)value{
NSMutableAttributedString*attriString = [[NSMutableAttributedString alloc] initWithString:[NSString stringWithFormat:@"%@ %@", title, value]];
[attriString addAttributes:@{NSFontAttributeName : [UIFont systemFontOfSize:15],
NSForegroundColorAttributeName : [UIColor blackColor]}
range:NSMakeRange(0, title.length)];
[attriString addAttributes:@{NSFontAttributeName : [UIFont systemFontOfSize:15],
NSForegroundColorAttributeName : [UIColor colorWithHexString:@"0x3bbd79"]}
range:NSMakeRange(title.length+1, value.length)];returnattriString;
}
11:UITableviewcell的accessoryType属性
cell.accessoryType = UITableViewCellAccessoryNone;//cell没有任何的样式 cell.accessoryType = UITableViewCellAccessoryDisclosureIndicator;//cell的右边有一个小箭头,距离右边有十几像素;cell.accessoryType = UITableViewCellAccessoryDetailDisclosureButton;//cell右边有一个蓝色的圆形button; cell.accessoryType = UITableViewCellAccessoryCheckmark;//cell右边的形状是对号;
12:layoutSubviews在以下情况下会被调用
a、init初始化不会触发layoutSubviews。
b、addSubview会触发layoutSubviews。
c、设置view的Frame会触发layoutSubviews,当然前提是frame的值设置前后发生了变化。
d、滚动一个UIScrollView会触发layoutSubviews。
e、旋转Screen会触发父UIView上的layoutSubviews事件。
f、改变一个UIView大小的时候也会触发父UIView上的layoutSubviews事件。
g、直接调用setLayoutSubviews。
13:导航栏的按键(自定义图片)
UIButton *settingBtn = [self navButtonWithImageName:@"settingBtn_Nav"action:@selector(settingBtnClicked:)];
self.navigationItem.rightBarButtonItem=[[UIBarButtonItem alloc] initWithCustomView:settingBtn];
UIButton*addUserBtn = [self navButtonWithImageName:@"addUserBtn_Nav"action:@selector(addUserBtnClicked:)];
self.navigationItem.leftBarButtonItem= [[UIBarButtonItem alloc] initWithCustomView:addUserBtn];
14:自定义表格行(继承UITableViewCell)
@interface TitleRImageMoreCell ()
@property (strong, nonatomic) UILabel*titleLabel;
@property (strong, nonatomic) UIImageView*userIconView;
@end
@implementation TitleRImageMoreCell- (id)initWithStyle:(UITableViewCellStyle)style reuseIdentifier:(NSString *)reuseIdentifier
{
self=[super initWithStyle:style reuseIdentifier:reuseIdentifier];if(self) {//Initialization codeself.accessoryType =UITableViewCellAccessoryDisclosureIndicator;if(!_titleLabel) {
_titleLabel= [[UILabel alloc] initWithFrame:CGRectMake(kPaddingLeftWidth, ([TitleRImageMoreCell cellHeight] -30)/2,100,30)];
_titleLabel.backgroundColor=[UIColor clearColor];
_titleLabel.font= [UIFont systemFontOfSize:16];
_titleLabel.textColor=[UIColor blackColor];
[self.contentView addSubview:_titleLabel];
}if(!_userIconView) {
_userIconView= [[UIImageView alloc] initWithFrame:CGRectMake((kScreen_Width- kTitleRImageMoreCell_HeightIcon)- kPaddingLeftWidth-30, ([TitleRImageMoreCell cellHeight] -kTitleRImageMoreCell_HeightIcon)/2, kTitleRImageMoreCell_HeightIcon, kTitleRImageMoreCell_HeightIcon)];
[_userIconView doCircleFrame];
[self.contentView addSubview:_userIconView];
}
}returnself;
}- (void)layoutSubviews{
[super layoutSubviews];if(!_curUser) {return;
}
self.titleLabel.text=@"头像";
[self.userIconView sd_setImageWithURL:[_curUser.avatar urlImageWithCodePathResizeToView:_userIconView] placeholderImage:kPlaceholderMonkeyRoundView(_userIconView)];
}+(CGFloat)cellHeight{return70.0;
}
@end
然后进行调用时(可以属性传值,并在不同的地方加载不同的行及其高度):- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath{if(indexPath.section ==0&& indexPath.row ==0) {
TitleRImageMoreCell*cell =[tableView dequeueReusableCellWithIdentifier:kCellIdentifier_TitleRImageMore forIndexPath:indexPath];
cell.curUser=_curUser;
[tableView addLineforPlainCell:cell forRowAtIndexPath:indexPath withLeftSpace:kPaddingLeftWidth];returncell;
}else{
TitleValueMoreCell*cell =[tableView dequeueReusableCellWithIdentifier:kCellIdentifier_TitleValueMore forIndexPath:indexPath];
}returncell;
}
15:当给按键的图标进行方向改变
[self setImage:[UIImage imageNamed:@"nav_arrow_down"] forState:UIControlStateNormal];
self.imageView.transform= CGAffineTransformRotate(self.imageView.transform, DEGREES_TO_RADIANS(180));//这这是进行180度转到,向下或向下
16:在导航栏中间增加一个带图片文字的控件
- (UIDownMenuButton *)initWithTitles:(NSArray *)titleList andDefaultIndex:(NSInteger)index andVC:(UIViewController *)viewcontroller{
self=[super init];if(self) {
_titleList=titleList;
_curIndex=index;
_curShowing=NO;
_mySuperView=viewcontroller.view;
self.backgroundColor=[UIColor clearColor];
[self setTitleColor:[UIColor whiteColor] forState:UIControlStateNormal];
[self setTitleColor:[UIColor lightGrayColor] forState:UIControlStateHighlighted];
[self.titleLabel setFont:[UIFont systemFontOfSize:kNavTitleFontSize]];
[self.titleLabel setMinimumScaleFactor:0.5];
[self addTarget:self action:@selector(changeShowing) forControlEvents:UIControlEventTouchUpInside];
[self refreshSelfUI];
}returnself;
}- (void)refreshSelfUI{
NSString*titleStr =@"";
DownMenuTitle*menuObj =[self.titleList objectAtIndex:self.curIndex];
titleStr=menuObj.titleValue;
CGFloat titleWidth= [titleStr getWidthWithFont:self.titleLabel.font constrainedToSize:CGSizeMake(kScreen_Width,30)];//获得文字的宽度CGFloat btnWidth = titleWidth +kNavImageWidth;
self.frame= CGRectMake((kScreen_Width-btnWidth)/2, (44-30)/2, btnWidth,30);
self.titleEdgeInsets= UIEdgeInsetsMake(0, -kNavImageWidth,0, kNavImageWidth);
self.imageEdgeInsets= UIEdgeInsetsMake(0, titleWidth,0, -titleWidth);
[self setTitle:titleStr forState:UIControlStateNormal];
[self setImage:[UIImage imageNamed:@"nav_arrow_down"] forState:UIControlStateNormal];
}
其中几个值:#definekNavTitleFontSize 19#definekScreen_Width [UIScreen mainScreen].bounds.size.width#definekNavImageWidth (15.0+5.0)然后直接赋给titleview:
UIDownMenuButton*navBtn =[[UIDownMenuButton alloc] initWithTitles:titleList andDefaultIndex:index andVC:self];
navBtn.menuIndexChanged=block;
self.navigationItem.titleView=navBtn;
注意:button都是有带文字跟图片的,只是图片都是在左边,要通过uiedgeinsetsmake对图片跟文字进行位置的改变。可以在导航栏的titleview做文章,放一些其它控件,或视图;
17:集合视图UICollectionView的简单使用
要遵循三个协议:UICollectionViewDataSource,UICollectionViewDelegate,UICollectionViewDelegateFlowLayout
设置单元格的布局
UICollectionViewFlowLayout*flowLayout =[[UICollectionViewFlowLayout alloc]init];
[flowLayout setItemSize:CGSizeMake(70,100)];//设置cell的尺寸[flowLayout setScrollDirection:UICollectionViewScrollDirectionVertical];//设置其布局方向flowLayout.sectionInset = UIEdgeInsetsMake(5,5,5,5);//设置其边界//其布局很有意思,当你的cell设置大小后,一行多少个cell,由cell的宽度决定然后设置集合视图:
_collectionView= [[UICollectionView alloc]initWithFrame:CGRectMake(0,0,320, self.view.frame.size.height) collectionViewLayout:flowLayout];
_collectionView.dataSource=self;
_collectionView.delegate=self;
_collectionView.backgroundColor=[UIColor clearColor];
[_collectionView registerClass:[BMCollectionCellclass] forCellWithReuseIdentifier:CELL_ID];
[self.view addSubview:_collectionView];
注意:其它委托事件没全写出,比如numberOfSectionsInCollectionView等;
