10：button顯示設(shè)置不同字體

[_headerFansCountBtn setAttributedTitle:[self getStringWithTitle:@"粉絲" andValue:_curUser.fans_count.stringValue] forState:UIControlStateNormal];方法（根據(jù)長(zhǎng)度來設(shè)置其不同的樣式顯示）：- (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)];return attriString; }

11:UITableviewcell的accessoryType屬性

cell.accessoryType?=?UITableViewCellAccessoryNone;//cell沒有任何的樣式?? cell.accessoryType?=?UITableViewCellAccessoryDisclosureIndicator;//cell的右邊有一個(gè)小箭頭，距離右邊有十幾像素； cell.accessoryType?=?UITableViewCellAccessoryDetailDisclosureButton;//cell右邊有一個(gè)藍(lán)色的圓形button；? cell.accessoryType?=?UITableViewCellAccessoryCheckmark;//cell右邊的形狀是對(duì)號(hào)；?

12:layoutSubviews在以下情況下會(huì)被調(diào)用

a、init初始化不會(huì)觸發(fā)layoutSubviews。 b、addSubview會(huì)觸發(fā)layoutSubviews。 c、設(shè)置view的Frame會(huì)觸發(fā)layoutSubviews，當(dāng)然前提是frame的值設(shè)置前后發(fā)生了變化。 d、滾動(dòng)一個(gè)UIScrollView會(huì)觸發(fā)layoutSubviews。 e、旋轉(zhuǎn)Screen會(huì)觸發(fā)父UIView上的layoutSubviews事件。 f、改變一個(gè)UIView大小的時(shí)候也會(huì)觸發(fā)父UIView上的layoutSubviews事件。 g、直接調(diào)用setLayoutSubviews。

13：導(dǎo)航欄的按鍵(自定義圖片)

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:自定義表格行（繼承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];}}return self; }- (void)layoutSubviews{[super layoutSubviews];if (!_curUser) {return;}self.titleLabel.text = @"頭像";[self.userIconView sd_setImageWithURL:[_curUser.avatar urlImageWithCodePathResizeToView:_userIconView] placeholderImage:kPlaceholderMonkeyRoundView(_userIconView)]; }+ (CGFloat)cellHeight{return 70.0; }@end然后進(jìn)行調(diào)用時(shí)（可以屬性傳值，并在不同的地方加載不同的行及其高度）：- (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];return cell; ｝ else { TitleValueMoreCell *cell = [tableView dequeueReusableCellWithIdentifier:kCellIdentifier_TitleValueMore forIndexPath:indexPath]; } return cell; ｝

15:當(dāng)給按鍵的圖標(biāo)進(jìn)行方向改變

[self setImage:[UIImage imageNamed:@"nav_arrow_down"] forState:UIControlStateNormal]; self.imageView.transform = CGAffineTransformRotate(self.imageView.transform, DEGREES_TO_RADIANS(180));//這這是進(jìn)行180度轉(zhuǎn)到，向下或向下

16:在導(dǎo)航欄中間增加一個(gè)帶圖片文字的控件

- (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];}return self; }- (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)];//獲得文字的寬度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]; }其中幾個(gè)值：#define kNavTitleFontSize 19 #define kScreen_Width [UIScreen mainScreen].bounds.size.width #define kNavImageWidth (15.0+5.0)然后直接賦給titleview：UIDownMenuButton *navBtn = [[UIDownMenuButton alloc] initWithTitles:titleList andDefaultIndex:index andVC:self];navBtn.menuIndexChanged = block;self.navigationItem.titleView = navBtn;注意：button都是有帶文字跟圖片的，只是圖片都是在左邊，要通過uiedgeinsetsmake對(duì)圖片跟文字進(jìn)行位置的改變。可以在導(dǎo)航欄的titleview做文章，放一些其它控件，或視圖；

17:集合視圖UICollectionView的簡(jiǎn)單使用

要遵循三個(gè)協(xié)議：UICollectionViewDataSource,UICollectionViewDelegate,UICollectionViewDelegateFlowLayout設(shè)置單元格的布局 UICollectionViewFlowLayout *flowLayout = [[UICollectionViewFlowLayout alloc]init]; [flowLayout setItemSize:CGSizeMake(70, 100)];//設(shè)置cell的尺寸 [flowLayout setScrollDirection:UICollectionViewScrollDirectionVertical];//設(shè)置其布局方向 flowLayout.sectionInset = UIEdgeInsetsMake(5, 5, 5, 5);//設(shè)置其邊界 //其布局很有意思，當(dāng)你的cell設(shè)置大小后，一行多少個(gè)cell，由cell的寬度決定 然后設(shè)置集合視圖： _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:[BMCollectionCell class] forCellWithReuseIdentifier:CELL_ID];[self.view addSubview:_collectionView];注意：其它委托事件沒全寫出,比如numberOfSectionsInCollectionView等；
